Abstract

Techniques and architecture are disclosed for a fuze setter adapter that operationally engages an incompatible fuze and fuze setter with each other so that fuze setting may be undertaken. The fuze and fuze setter each include at least one wireless or direct connect interface for electrical power transfer and/or data communications. The fuze setter adapter provides complementary interfaces configured to couple with the interfaces of the fuze and fuze setter. A processor control in the fuze setter adapter links the fuze setter adapter interfaces. The processor control is programmed to receive data communications from the fuze setter, convert those signals to fuze-compatible signals, and transfer the fuze-compatible signals to the fuze, and vice versa. The processor control is further programmed to receive electrical power from the fuze setter, convert that electrical power to fuze-compatible power, and transfer the fuze-compatible power to the fuze.

Description

FUZE SETTER ADAPTER SYSTEMS AND TECHNIQUES

TECHNICAL FIELD

[0001] The following disclosure relates generally to fuze setting systems and, in particular, to a fuze setter adapter utilized to operatively engage a fuze with an incompatible fuze setter and enable communication between the fuze and incompatible fuze setter so that fuze setting is able to occur.

BACKGROUND

[0002] Artillery fuzes are typically attached to a leading end of an artillery projectile prior to launch from a gun platform. Fuze setting is the process of quickly programming targeting and other data into artillery fuzes. Fuze setting has to occur prior to launch and is typically accomplished by engaging the fuze with a fuze setter. The fuze setter may be part of an autoloader system used to automatically load artillery projectiles into the gun platform while minimizing the need for operator intervention. Alternatively, the fuze setter may be a handheld device that is brought into engagement with the nose of the artillery fuze.

[0003] Legacy fuze setters for artillery fuzes have used inductive coupling- based communications and power transfer interfaces to transfer targeting and other information to legacy fuzes prior to launch. Electrical power has also been transferred from the legacy fuze setter to the legacy fuze during fuze setting.“Next generation” artillery fuzes, i.e. , artillery fuzes with precision guidance capability that can correct for firing errors and steer the projectile to a desired target impact point, require larger amounts of data to be transferred to them during fuze setting. Interfaces on legacy fuze setters are too slow to transfer the quantity of data necessary to next generation fuzes in the short time available for the fuze setting process prior to launch. Additionally, next generation fuzes may incorporate a different high speed interface that is not backwards compatible with legacy inductive fuze setters. This incompatibility between the legacy fuze setters and the next generation fuzes typically prevents next generation fuzes from being programmed by legacy fuze setters, even if the slower data transfer can be tolerated. Legacy fuzes and next generation fuze setters are also incompatible for similar reasons and this incompatibility prevents legacy fuzes from being programmed by next generation fuze setters. This situation is problematic because there are significant existing inventories of legacy fuze setters that cannot be used to program next generation fuzes and, conversely, inventories of legacy fuzes that cannot be programmed using next generation fuze setters.

[0004] Different types of next generation fuzes and next generation fuze setters may also be incompatible because they use different components to transfer electrical power and data signals.

SUMMARY

[0005] The present disclosure is directed to a fuze setter adapter that is capable of mating with a fuze and a fuze setter which are typically incompatible with each other, and enabling a fuze setting operation to occur despite the inherent incompatibility between the fuze and fuze setter. Internal electronics in the fuze setter adapter supports data capture, storage, and reformatting as the communications protocols on either side of the fuze setter adapter may require. The fuze setter adapter also supports the ability to convert electrical power input from a legacy fuze setter into a form compatible with a next generation fuze. Power for the fuze setter adapter may be derived from the fuze setter, thereby avoiding the need for a separate power supply for the fuze setter adapter.

[0006] A first exemplary fuze setter adapter is disclosed herein that provides both an inductive communications interface and a direct connect power interface. The first exemplary fuze setter adapter disclosed herein contains electronics capable of communicating with legacy fuze setters (via the inductive interface) and with the next generation fuze (via the direct connect interface). A second exemplary fuze setter adapter is disclosed herein that provides an inductive communications interface and an inductive power interface. The second exemplary fuze setter adapter disclosed herein contains electronics capable of communicating with legacy fuze setters and with the next generation fuze via two separate inductive interfaces.

[0007] An example embodiment of the present disclosure provides a system including a fuze having an interface; a fuze setter having an interface; and a fuze setter adapter configured to operatively communicate with both the fuze and the fuze setter, wherein the fuze setter adapter is mated to the fuze setter. [0008] Particular implementations may include one or more of the following features. The system may further comprise a control element situated inside the fuze setter adapter, wherein the control element is configured to handle communications operations including data translation, data buffering other data manipulation operations as may be necessary, and communications operations between fuze setter and fuze, as well as electrical power conversion and distribution to the fuze. The control element may further comprise processor control capability. The interface of the fuze may be incompatible with the interface of the fuze setter.

[0009] Another example embodiment provides a system including a fuze having an interface and a fuze setter having an interface. There is a fuze setter adapter configured to operatively communicate with both the fuze and the fuze setter, wherein the fuze setter adapter is mated to the fuze setter. A locking mechanism may be provided to secure the fuze setter adapter to one or both of the fuze and fuze setter. A process control element is provided on the fuze setter adapter.

[0010] Particular implementations may include one or more of the following features. The interface of the fuze may be incompatible with the interface of the fuze setter. The interface to the fuze may be one or more of an electrical direct connect interface and a wireless interface, where the wireless interface may include one or more induction coils, optical transceivers, and radio frequency (RF) transceivers. In some examples, optical transceivers and RF transceivers are used for communications and inductive interfaces are used for electrical power transfer. The interface of the fuze may be an inductive communications interface, and it may be a direct connect communications interface, whereby direct connect refers to a direct electrical connection interface, or more broadly, a non-inductive interface. The interface of the fuze setter may be the inductive communications interface, and it may be the direct connect communications interface. The system may include a processor control capability.

[0011] In one aspect, an exemplary embodiment of the present disclosure may provide a method of fuze setting comprising engaging a fuze setter adapter between a fuze setter and a fuze, where the fuze setter and the fuze are incompatible with each other; establishing communication between the fuze setter adapter and both the fuze setter and the fuze; transferring fuze setting data from the fuze setter to the fuze setter adapter; and transferring the fuze setting data from the fuze setter adapter to the fuze.

[0012] In one exemplary embodiment, the transferring of the fuze setting data from the fuze setter to the fuze setter adapter further comprises encoding the fuze setting data into waveforms; and transferring the waveforms of the encoded fuze setting data from the fuze setter to the fuze setter adapter. In one example, the method further comprises receiving the waveforms of the encoded fuze setting data; decoding the fuze setting data from the waveforms; encoding the decoded fuze setting data into a fuze-compatible format; and transferring the fuze-compatible format of the fuze setting data from the fuze setter adapter to the fuze. In one exemplary embodiment, the method includes transferring the waveforms of the encoded fuze setting data from the fuze setter to the fuze setter adapter via a first interface; and transferring the fuze- compatible format of the fuze setting data from the fuze setter adapter to the fuze via a second interface. In one example, the method includes utilizing one of a direct connect interface and a wireless interface as one or both of the first interface and the second interface.

[0013] In one exemplary embodiment, the method further comprises applying electrical power from the fuze setter to the fuze setter adapter; generating fuze- compatible electrical power; and applying the fuze-compatible electrical power to the fuze. In one example, one or both of applying of electrical power from the fuze setter to the fuze setter adapter and applying of the fuze-compatible electrical power occurs through utilizing one of a direct connect interface and a wireless interface.

[0014] In an exemplary embodiment, the method further comprises sending a discrete electrical signal from the fuze setter to the fuze setter adapter; converting the discrete electrical signal to a fuze-compatible format; and sending the converted discrete electrical signal from the fuze setter adapter to the fuze. In one example, the method further includes sending a fuze discrete electrical signal from the fuze to the fuze setter adapter; converting the fuze discrete electrical signal to a fuze-setter- compatible format; and sending the converted fuze discrete electrical signal from the fuze setter adapter to the fuze setter.

[0015] In one exemplary embodiment, the method further comprises engaging the fuze with the fuze setter adapter via a first mechanical interface; and engaging the fuze setter adapter with the fuze setter via a second mechanical interface. In one embodiment, the method further includes utilizing programming provided in a processor control of the fuze setter adapter to perform one or more of an electrical signal conversion, a communications conversion, and a communications translation on the fuze setting data prior to transferring the fuze setting data from the fuze setter adapter to the fuze.

[0016] In one aspect, an exemplary embodiment of the present disclosure may provide a fuze setting system comprising a fuze and a fuze setter; wherein the fuze and the fuze setter are incompatible in a way that prevents the fuze setter from performing a fuze setting operation on the fuze; and a fuze setter adapter configured to matingly engage and communicate with the fuze and the fuze setter such that the fuze setting operation is able to occur.

[0017] In another aspect, an exemplary embodiment of the present disclosure may provide a fuze setter adapter, comprising a first interface adapted to couple with a fuze; a second interface adapted to couple with a fuze setter, where the fuze setter is incompatible with the fuze; a processor control operatively engaged with the first interface and the second interface; wherein programming provided in the processor control establishes communication between the fuze and the fuze setter and enables fuze setting to occur.

[0018] In one exemplary embodiment, each of the first interface and the second interface is one or more of an electrical signal interface, an electrical power interface, and a communications interface. In one example, each of the first interface and the second interface is one or more of a wireless interface and a direct connect interface. In one example, the wireless interface is one of an inductive coil, a Radio Frequency (RF) transceiver, a Height of Burst (HoB) sensor, and an optical transceiver. In one example, the direct connect interface is one of a contact pad, a continuous contact ring, a segmented contact ring, and a contact pin. In one example, the fuze setter adapter includes a first mechanical interface adapted to engage the fuze; and a second mechanical interface adapted to engage the fuze setter.

[0019] In another aspect, an exemplary embodiment of the present disclosure may provide a fuze setting system, comprising a fuze adapted to be engaged with a projectile; a fuze setter; wherein the fuze and the fuze setter are incompatible in at least one way that prevents fuze setting; and a fuze setter adapter configured to matingly engage with the fuze and the fuze setter; said fuze setter adapter including a processor control that establishes communication between the fuze and the fuze setter such that fuze setting occurs.

[0020] In one example, the fuze setting system includes a fuze interface provided on the fuze; a fuze setter interface provided on the fuze setter; wherein the fuze interface and the fuze setter interface are incompatible; a first interface provided on the fuze setter adapter that couples with the fuze interface; and a second interface provided on the fuze setter adapter that couples with the fuze setter interface; and wherein the processor control is engaged with the first and second interface. In one example, the fuze interface, the fuze setter interface, the first interface, and the second interface are all electrical signal interfaces and the processor control enables bi- directional communication between the fuze setter and the fuze. In one example, the fuze interface, the fuze setter interface, the first interface, and the second interface are all electrical power interfaces; and the processor control enables electrical power to be transferred from the fuze setter to the fuze.

[0067] Similar numbers refer to similar parts throughout the drawings. DETAILED DESCRIPTION

[0068] FIG. 1 shows a fuze setting system that includes a PRIOR ART legacy fuze 10 and a PRIOR ART legacy fuze setter 12. The PRIOR ART legacy fuze 10 will be referred to hereafter as“LF 10" and the PRIOR ART legacy fuze setter will be referred to hereafter as “LFS 12”. The system uses an inductive interface for communications and electrical power transfer between LF 10 and LFS 12. LFS 12 and LF 10 are compatible with each other and LFS 12 is able to be utilized to perform a fuze setting operation on LF 10.

[0069] LF 10 includes a housing 14 having a front end 14a and a rear end 14b. The housing 14 defines an interior compartment 14c. A region of LF 10, including rear end 14b, is configured to be engaged with a projectile (not shown). A nose region of LF 10, including front end 14a, is tapered and configured to be engaged with a LFS 12. An inductive interface coil 16 is provided within compartment 14c of the nose region. It will be understood that coil 16 is operatively engaged with an electronic system provided on LF 10.

[0070] LFS 12 includes a housing 18 having a wall 18a with an opening to a chamber 18b defined therein. Chamber 18b is bounded and defined by an inwardly extending and tapered sidewall 18c and an end wall 18d and is shaped to receive the nose region of LF 10 therein. An inductive coil 20 is provided within LFS 12 with that coil 20 being located adjacent to interior wall 18b.

[0071] As indicated by the arrow“A”, LF 10 is selectively inserted into chamber 18b of LFS 12. When LF 10 is received within chamber 18b, an inductive interface is formed via inductive coupling of inductive coil 16 and inductive coil 20. The inductive interface is utilized for communications and electrical power transfer between LFS 12 and LF 10. In particular, the inductive interface is used to alternately transfer communications and electrical power between LFS 12 and LF 10. Because of the alternating nature of the communications and electrical power transfer in this system, a relatively long time is required to transfer the necessary data and power from LFS 12 to LF 10.

[0072] LF 10 and LFS 12 are compatible with respect to a mechanical interface, i.e., the nose region of the LF 10 is complementary to the chamber 14c in LFS 12 and is able to be received therein. The inductive coil 16 in LF 10 inductive coil 20 in LFS 12 are configured to inductively couple and permit power and data to move from LFS 12 to LF 10. LFS 12 is sufficiently compatible with LF 10 to perform a fuze setting operation on LF 10.

[0073] “Next generation” fuzes and fuze setters, such as those illustrated in FIG. 2, transfer electrical power and communications differently from LS 10 and LFS 12. A number of next generation fuzes and next generation fuze setters are disclosed in PCT application number PCT/US2019/014682, filed January 23, 2019, and in United States patent application serial number 16/294,505 filed March 6, 2019. In particular, a plurality of embodiments of direct connect next generation fuzes and fuze setters is disclosed in PCT/US2019/014682. These direct connect fuzes and fuze setters transfer electrical power and high speed communications and data through complementary electrical contacts provided on the fuze and fuze setter. With respect to the present disclosure, the fuzes illustrated in FIGS. 2 through 11 and FIG. 18A, and the fuze setter illustrated in FIGS. 17A through 17E, and FIG. 18B, are examples of next generation direct connect fuzes and fuze setters disclosed in PCT/US2019/014682.

[0074] US16/294,505 discloses a plurality of embodiments of next generation fuzes and fuze setters that communicate wirelessly, i.e., through induction coils, Radio Frequency (RF) transceivers, optical transceivers, and/or Height of Burst (HoB) sensors. These devices enable wireless transfer of electrical power as well as high speed communications and data. With respect to this disclosure, the fuzes illustrated in FIGS. 12A through 15 and the fuze setters illustrated in FIGS. 17F through 18A, are examples of next generation wireless fuzes and fuze setters disclosed in US16/294,505.

[0075] It should be understood that the direct connect next generation fuzes and next generation fuze setters, and the wireless next generation fuzes and next generation fuze setters illustrated and discussed herein are exemplary only and other, differently configured next generation fuzes and fuze setters may be utilized with the fuze setter adapter that is the subject of the present disclosure. Some details of the structure and functioning of the exemplary next generation fuzes and fuze setters is provided herein. For more complete information as to the structure and function of these next generation fuzes and fuze setters, the referenced PCT and US patent applications may be reviewed. In the following description, the term“next generation fuze” will be referred to hereafter by the acronym“NGF”, the term "next generation fuze setter” will be referred to by the acronym“NGFS”, and the term“fuze setter adapter” will be referred to herein by the acronym TSA”.

[0076] FIG. 2 is a side elevation view of a first embodiment of a NGF 100 and a first embodiment of a NGFS 102 that is compatible with NGF 100 and is typically used to perform a fuze setting operation on NGF 100. NGF 100 and NGFS 102 are exemplary of next generation fuzes and fuze setters that utilize an exemplary direct connect interface for communications and electrical power transfer.

[0077] NGF 100 includes a radome housing 104 and a fuze body 106 that are operatively engaged with each other. Radome housing 104 includes an exterior sidewall 104a, a front end 104b, and a rear end 104c. Sidewall 104a and front end 104b bound and define an interior cavity within which various components are housed. Radome housing 104 forms the nose or nose region of NGF 100. Fuze body 106 includes an exterior sidewall 106a having a first end 106b (FIG. 2), a second end 106c and an extension 106d that extends rearwardly from second end 106c. Extension 106d is of a smaller circumference than sidewall 106a and is adapted to be received within a cavity of a projectile body. The projectile body is fabricated from a material, such as metal, that is structurally sufficient to enable projectile 10 to carry an explosive charge. Together, NGF 100 and the projectile body comprise a guided projectile. The sidewall 106a of NGF 100 bounds and defines an interior cavity within which a number of components are housed. First end 106b of fuze body 106 is operatively engaged with rear end 104c of radome housing 104 or be integrally formed therewith. NGF 100 has a longitudinal axis Ύ" extending between front end 104b of radome housing 104 and an end 106e of extension 106d. Extension 106d of fuze body 106 is coupled to a coupling region of the projectile body. The engagement between NGF 100 and the projectile body is one that permits NGF 100 to rotate relative to the projectile body and about longitudinal axis Ύ”.

[0078] Referring still to FIG. 2, one or more canards 108 are provided on fuze body 106. Canards 108 are utilized to alter the trajectory of the projectile while in flight and are operatively engaged with a control actuation system (not shown) located within fuze body 106. Although not illustrated herein, it will be understood that NGF 100 may include various systems within radome housing 104 and fuze body 106. These systems typically will include a guidance, navigation, and control (GNC) assembly that includes a Global Positioning System (GPS) receiver. At least one GPS antenna 110 (FIG. 2) is provided on an exterior surface of the sidewall 106a. The GNC assembly may include a plurality of other sensors, including, but not limited to, laser guided sensors, electro-optical sensors, imaging sensors, inertial navigation systems (INS), inertial measurement units (IMU), and any other sensors suitable or necessary to navigate and guide the projectile to a location programmed during fuze setting. NGF 100 typically includes at least one non-transitory computer-readable storage medium and at least one processor or microprocessor housed within fuze body 106. The storage medium may include instructions encoded thereon that, when executed by the processor or microprocessor, implements various functions and operations to aid in guidance, navigation and control of the guided projectile. A power source, such as a battery, is operatively engaged with any of the aforementioned components that require power to operate. In some examples, some of the above-mentioned components may be omitted from NGF 100. In other examples, additional components may be included in NGF 100. Some or all of the components are operatively engaged with each other via wiring. It will be understood that any type of connection may be provided between the various components within NGF 100.

[0079] NGF 100 includes a first configuration of electrical contacts and NGFS 102 includes a complementary electrical contact configuration. The first embodiment electrical contact configurations of NGF 100 and NGFS 102 form an electrical interface between NGF 100 and NGFS 102. The electrical interface enables power and/or data to be transferred from NGFS 102 to NGF 100 during a fuze setting operation. FIG. 2 shows that the first configuration of electrical contacts on NGF 100 comprises a plurality of electrical contact pads 1 12 provided on the exterior surface of sidewall 104a of radome housing 104. Contact pads 112 are utilized as a direct connect interface for both communications and electrical power transfer.

[0080] A single segmented ring of contact pads 112 with any desired number of discrete, spaced-apart contact pads is provided. The segmented ring shown in FIG.

2 includes eight discrete electrical contact pads 112. In one example, the electrical contact pads 112 comprise two power electrical contact pads, two loopback electrical contact pads, two Time Mark Indicator (TMI) electrical contact pads, and two serial communications electrical contact pads. One electrical contact pad 112 is provided for each signal. Electrical contact pads 112 are operatively engaged with an electronic system of NGF 100 via wiring. For example, each electrical contact pad 112 is operatively engaged with one or more of the computer readable storage medium, the processor, the battery and any other electronic components on NGF 100. The TMI electrical contact pads, for example, are utilized in the transfer of GPS time signals from NGFS 102 to NGF 100, allowing NGF 100 to synchronize to GPS time. TMI signals are only relevant to examples of NGF 100 that utilize GPS. In other examples of NGF 100, these TMI electrical contact pads are used for other purposes, or they can be omitted.

[0081] The location of electrical contact pads 112 on sidewall 104a as illustrated in FIG. 2 helps to avoid obscuration of any Height of Burst (HoB) sensor transmitter located within radome housing 104. There is furthermore more surface area available on sidewall 104a than on front end 104b and therefore the use of larger electrical contact pads 1 12 is possible than if the electrical contact pads were placed on front end 104a. Electrical contact pads 112 are shown positioned closer to rear end 104c of radome housing 104, thus providing a shorter electrical path length to electronics within radome housing 104. Placing electrical contact pads 1 12 on sidewall 104a makes them more readily accessed by NGFS 102 if the fuze setter utilizes a nose approach, a side approach, or a clamshell approach for engaging with NGF 100. The placement of contact pads 112 on sidewall 104a also helps to accommodate larger mechanical misalignments between contact pads 112 and complementary electrical contacts provided on NGFS 102. (The electrical contacts on NGFS 102 will be described later herein.) Furthermore, placing electrical contact pads 112 on sidewall 104a may allow for higher electrical current carrying ability (for power / ground signals). Since there are eight electrical contact pads 112, the connection to electronics within radome housing 104 is simplified.

[0082] Electrical contact pads 112 are applied to sidewall 104a in any suitable manner. One suitable manner may be through contact metallization. In one example, electrical contact pads 112 may be bonded to the exterior surface of sidewall 104a using an adhesive. In one example, a recess is defined in the exterior surface of sidewall 104a for each electrical contact pad 1 12 and an associated electrical contact pad is placed into each recess. In one example, an outermost surface of the electrical contact pad 1 12 within a recess is substantially flush with the exterior surface of the sidewall 104a. In one example, an outermost surface of the electrical contact pad 112 within a recess is located a short distance outwardly beyond the exterior surface of the sidewall 104a. In one example, an outermost surface of the electrical contact pad 112 within a recess is located a short distance inwardly from the exterior surface of the sidewall 104a. Electrical contact pads 112 are arranged in a rotationally symmetric pattern. This rotationally symmetric pattern aids in accommodating an unknown rotational orientation of NGF 100 when the fuze is engaged by NGFS 102. Providing electrical contact pads 112 in a rotationally symmetric pattern also helps to avoid the need to physically rotationally orient NGF 100 prior to engagement with NGFS 102.

[0083] FIG. 2 shows electrical contact pads 112 arranged in pattern on the sidewall 104a. Electrical contact pads are arranged an annular ring that circumscribes the exterior surface of sidewall 104a and are spaced circumferentially from each other around the circumference of sidewall 104a. In one example, the electrical contact pads 112 are spaced at regular intervals around the circumference of sidewall 104a. In one example, adjacent electrical contact pads 112 are separated from each other by a space or by a section of sidewall 104a. Each electrical contact pad 112 and each space extends longitudinally rearwardly away from front end 104a. In one example, each electrical contact pad 112 is generally rectangularly-shaped when sidewall 104a is viewed from the side. In one example, electrical contact pads 112 are aligned with each other along a vertical plane "X” that is oriented at right angles to longitudinal axis

[0084] NGFS 102 includes a housing 114 having a wall 1 14a defining an opening to a port 114b. Port 114b is bounded and defined by an interior sidewall 114c and an interior front wall 1 14d of NGFS 102. The sidewall 114c and front wall 114d are shaped to be complementary to the exterior surfaces of a nose region of NGF 100. Port 114b is of slightly greater dimensions than the nose region of NGF 100 so that the nose region is received within port 114b. The nose region of NGF 100 is introduced into port 114b through the opening defined in wall 114a either manually or by an autoloader.

[0085] NGFS 102 includes a plurality of electrical contacts configured to come into direct contact with contact pads 112 of NGF 100 to form an direct connect interface. Electrical contacts 1 16 are arranged in a pattern complementary to the pattern of electrical contact pads 112 on NGF 100. As illustrated, electrical contacts 116 are arranged in an annular ring that circumscribes an interior surface of sidewall 114c that bounds port 114b. Contacts 1 16 are spaced circumferentially from each other around the circumference of sidewall 114c. In one example, the contacts 116 are spaced at regular intervals around the circumference of sidewall 114c. In one example, adjacent contacts 116 are separated from each other by a space or by a section of sidewall 1 14c.

[0086] Electrical contacts 116 may be of any construction that will establish an electrical connection with electrical contact pads 1 12. In one example, the electrical contacts 116 on NGFS 102 are spring contacts such as axially aligned electrical contacts 116 (e.g. pogo electrical contact pins) or any other configuration of spring contact that provides mechanical compliance and wiping action. The electrical contacts 116 are used for transfer of electrical power or signals. It will be understood that the electrical contacts 116 on NGFS 102 are not limited to electrical contact pins but may be of any other desired construction. Electrical contacts 116 are capable of transferring power or data to electrical contact pads 112.

[0087] Electrical contacts 116 are arranged in a pattern substantially identical to the pattern of electrical contact pads 112 on NGF 100. Electrical contacts 116 arranged radially on NGFS 102 are capable of extending outwardly beyond the interior surface of sidewall 114c and into port 114b. Electrical contacts 116 are aligned with each other along a vertical plane“XT’ that is oriented at right angles to the longitudinal axis Ύ1” of fuze setter port 114b. Electrical contacts 116 are arranged in a circular pattern. In one example there are equivalent numbers of electrical contact pads 112 on NGF 100 and electrical contacts 116 on NGFS 102. In other words, there is a one- to-one ratio between electrical contact pads 112 and electrical contacts 116. Electrical contacts 116 are operatively engaged with the electronics within NGFS 102 and are utilized to transfer power and/or data to NGF 100.

[0088] The placement of electrical contacts 116 on sidewall 114c is such that when radome housing 104 is received in port 114b, electrical contacts 116, and electrical contact pads 112 will come sufficiently into alignment and contact with each other that an electrical interface is formed between them. Each electrical contact pad 112 engages a corresponding electrical contact pin 116 on NGFS 102 that is unassigned to a signal. In one example, power will be transferred from NGFS 102 to NGF 100 via the interface formed between electrical contacts 116 and electrical contact pads 112. In one example, data will be transferred or shared between NGFS 102 and NGF 100 via the interface formed between electrical contacts 116 and electrical contact pads 112. In one example, data will be bi-directionally shared between NGFS 102 and NGF 100 via this interface.

[0089] The placement of electrical contact pads 112 relative to the placement of electrical contacts 1 16 and thereby the development of the electrical interface is such that no matter the rotational orientation of NGF 100 relative to projectile body 20 (and to NGFS 102), power and/or data is able to be transferred across the interface. The illustrated and described configuration of electrical contact pads 112 and electrical contacts 116 negates the need for a specific physical orientation of NGF 100 to be adopted relative to NGFS 102 before power/and or data is able to be transferred between NGFS 102 and NGF 100. When NGF 100 is placed on an autoloader and is engaged by NGFS 102, the fuze rotational position is initially undefined relative to NGFS 102.

[0090] In one example, feedthroughs on each of electrical contact pads 112 can be used to bring electrical signals through to the interior of the radome housing 104, e.g. via wiring 44, where electrical contact can be made using conventional techniques. These feedthroughs allow fuze setting to occur. In other words, the feedthroughs permit downloading of programs that include targeting information into NGF 100. The feedthroughs also enable power to be transferred to NGF 100. The feedthroughs are engaged with the electronic system of NGF 100. The system of NGF 100 and NGFS 102 is able to use fuze setting for other purposes. For example, the system may be used for periodic monitoring of the fuze while the fuze is in storage, and/or reprogramming the fuze operating software in a more efficient manner. The system may also be used as a general communications interface for purposes including status query, and for checking fuze configuration, including part number, serial number, and revision. The interface may further be used to initiate built-in testing and other diagnostic tests of NGF 100, and may have NGF 100 report back the results of the test. In other examples, the disclosed interface may also be utilized to test equipment used to support various diagnostic, maintenance and upgrade and repair functions. The test equipment could incorporate an interface akin to what is used on NGF 100 and NGFS 102.

[0091] NGF 100 and NGFS 102 are compatible with respect to a mechanical interface, i.e., the nose region of the NGF 100 is complementary to the NGFS 102 and is able to be received therein. NGF 100 and NGFS 102 are compatible with respect to an electrical signal interface, electrical power interface and electrical communication interface in that the contact pads 1 12 of NGF 100 and electrical contacts 116 of NGFS 102 are configured to communicate with each other. NGFS 102 is sufficiently compatible with NGF 100 to perform a fuze setting operation on NGF 100.

[0092] FIG. 3A is a diagrammatic longitudinal section of LF 10 and LFS 12 located on the drawing sheet above the exemplary NGF 100 and NGFS 102. This figure is provided to show that there is inherent incompatibility between the NGF 100 and the LFS 12. In particular, the legacy induction coil 20 of LFS 12 is incapable of establishing communication and electrical power interfaces with the direct connect electrical contact pads 112 of NGF 100. Additionally, an adequate mechanical interface may not be able to be formed because of the different shape of the nose region of NGF 100 and the chamber defined by LFS 12. LFS 12 is unable to perform a fuze setting operation on NGF 100 because of this incompatibility.

[0093] Similarly, FIG. 3B is a side elevation view of LF 10 and LFS 12 located on the drawing sheet above the exemplary NGF 100 and NGFS 102. This figure is provided to show that there is inherent incompatibility between the LF 10 and NGFS 102. In particular, the direct connect electrical contacts 116 of NGFS 102 are inherently incapable of establishing communication and electrical power interfaces with the legacy induction coil 16 of LF 10. Additionally, an adequate mechanical interface may not be able to be formed because of the different shape of the nose region of LS 10 and the chamber defined by NGFS 102. NGFS 102 is therefore unable to perform a fuze setting operation on LF 10 because of this incompatibility.

[0094] In order to resolve the inherent incompatibility between various fuzes and fuze setters and to enable a fuze setter to perform a fuze setting operation on an incompatible fuze, a fuze setter adapter in accordance with the present disclosure is described hereafter and is shown in the attached figures. [0095] An example of the fuze setter adapter disclosed herein is capable of being coupled with and establishing engagement and communication between a fuze and an incompatible fuze setter. The fuze and fuze setter are incompatible in at least one aspect relative to each other. Aspects that cause incompatibility include but are not necessarily limited to, that a mechanical interface is not possible because of a difference in an exterior shape of the nose region of the fuze relative to a chamber defined in the fuze setter; one of the fuze and fuze setter utilizes direct connect technology and the other of the fuze and fuze setter utilizes wireless technology, one of the fuze and fuze setter utilizes legacy technology and the other of the fuze and fuze setter utilizes next generation technology; or the fuze and fuze setter transmit and receive data at different rates. Data is typically communicated between fuze and fuze setter via a set of messages, each message defined to transmit a defined set of data. For example, a status message to communicate status, a control message to communicate a command to be executed, etc. Each message comprises a message header and a data block. The structure of the message (size, data content, location of specific data elements within the data block) must be commonly understood between both fuze and fuze setter. The fuze and fuze setter might therefore be incompatible if the structure of the messages from the fuze setter, for example, was not understood by the fuze. Another factor that results in incompatibility between fuze setter and fuze is that the fuze and fuze setter have different power capabilities, e.g., the fuze setter provides either a higher or lower electrical voltage than the fuze requires to operator, or provides Alternating Current (AC) power via an inductive interface where the fuze requires Direct Current (DC power, in which case electrical voltage conversion is necessary. In other instances, the fuze setter may output a DC voltage different (either higher or lower) than what the fuze requires to operate. Many other factors could affect compatibility between fuze and fuze setter and thereby prevent fuze setting from being able to occur. The fuze setter adapter disclosed herein is provided to resolve these incompatibility issues. For example, one of the functions of the fuze setter adapter in accordance with the present disclosure would be to receive messages from the fuze setter, extract the data, and reformat the data into a message format compatible with what the fuze is expecting, and vice versa from fuze to fuze setter as necessary. In other examples where the fuze and fuze setter have different power capabilities, the fuze setter adapter would accept the input power from the fuze setter and convert it into a form compatible with what the fuze requires.

[0096] In accordance with an aspect of the present disclosure, an example of a fuze setter adapter is disclosed herein that is capable of being coupled with and establishing communication and electrical power interfaces between a legacy fuze and an incompatible next generation fuze setter. As will be further discussed herein the fuze setter adapter is configured to be interposed between the legacy fuze and the next generation fuze setter and to be matingly engaged therewith.

[0097] In accordance with an aspect of the present disclosure, an example of a fuze setter adapter is disclosed that is capable of being coupled with and establishing communication and electrical power interfaces between a next generation fuze and an incompatible next generation fuze setter. As will be further discussed herein this example of the fuze setter adapter is configured to be interposed between the next generation fuze and the next generation fuze setter and to be matingly engaged therewith.

[0098] In accordance with an aspect of the present disclosure, an example of a fuze setter adapter is disclosed that is capable of being coupled with and establishing communication and electrical power interfaces between any fuze and any fuze setter that are incompatible with each other because of their physical shapes. As will be further discussed herein this example of the fuze setter adapter is configured to be interposed between the fuze and fuze setter and to be matingly engaged therewith.

[0099] Although the narrative of this disclosure largely addresses legacy versus next generation fuzes and fuze setters, it will be understood that a fuze setter adapter in accordance with the present disclosure may be utilized with a variety of different families of fuzes that would otherwise be incompatible with a fuze setter designed for one type of fuze only, and vice versa. Thus, in accordance with an aspect of present disclosure, one example of a fuze setter is able to communicate with a variety of different fuze types by individually and independently engaging an appropriate fuze setter adapter between each of the different fuzes and the fuze setter. In other words, in this particular example, the fuze setter adapter will only couple with a single fuze and a single fuze setter. In other exemplary embodiments, a single fuze type could be programmed across a variety of otherwise incompatible fuze setters if a compatible fuze setter adapter in accordance with the present disclosure is used. Again, in this particular embodiment, each of the different fuze setters will be individually and independently coupled with the fuze setter adapter so that one fuze and fuze setter is engaged with the fuze setter adapter. Later in this disclosure, a fuze setter adapter is disclosed that is able to be utilized as a general or universal fuze setter adapter that resolves incompatibility between a variety of different fuzes and fuze setters. In yet another exemplary embodiment, a fuze setter adapter has one interface to a fuze setter and multiple fuze interfaces that are configured to accommodate more than one type of fuze, and vice versa. In the latter example, the fuze setter adapter would have one interface to a particular fuze type, and multiple interfaces to support different fuze setters.

[0100] FIGS. 4 through 11 show a variety of next generation fuzes that include various electrical contact pad arrangements that are able to be interfaced with a common fuze setter through the provision of an example of a fuze setter adapter in accordance with the present disclosure. The common fuze setter illustrated in these figures is LFS 12 (FIG. 1) but it will be understood that any a different fuze setter may be utilized as the common fuze setter provided appropriate changes are made to the fuze setter adapter that is utilized. This will be explained in greater detail below.

[0101] Referring now to FIGS. 3A, 3B, and 4A through 4C, there is shown LFS 12 and a NGF 100 that are inherently incompatible. A first embodiment of a FSA 130 in accordance with an aspect of the present disclosure is utilized to interface between NGF 100 and LFS 12. In other words, FSA 130 enables LFS 12 and NGF 100 to matingly engage with other and establish communication with each other.

[0102] FSA 130 has a first region 130A configured to engage with NGF 100 and a second region 130B configured to engage with LFS 12. FSA 130 includes a housing 132. Housing 132 in first region 130A of FSA 130 includes a wall 132a that defines an opening to a port 132b defined by housing 132. In particular, port 132b is bounded and defined by an inwardly extending and tapered sidewall 132c and an end wall 132d. Port 132b is shaped and sized to be complementary to the nose region of NGF 100 and to physically receive the nose region therein. Port 132b comprises a first mechanical interface provided on FSA 130 and is utilized to matingly engage with NGF 100. [0103] The first region 130A of FSA 130 includes a plurality of electrical contacts 134 that are of a substantially identical construction, placement and function as electrical contacts 1 16 of the aforementioned NGFS 102 (FIG. 2). Electrical contacts 134 are configured to selectively extend into cavity 132b of fuze setter adapter and come into direct contact with contact pads 112. When radome housing 104 is physically received in port 132b, there is direct contact between electrical contacts 134 and contact pads 112 and this results in a high power, low speed interface for efficient electrical power transfer from FSA 130 to NGF 100 and high speed bi-directional communication between FSA 130 and NGF 100.

[0104] Second region 130B of FSA 130 comprises a connector region that is complementary in shape and size to the chamber 18b defined by LFS 12. The second region 130B, i.e. , the connector region, comprises a second mechanical interface provided on FSA 130 and is utilized to matingly engage the fuze setter adapter and LFS 12. The second region 130B is configured to be physically received within chamber 18b of LFS 12. The connector region as illustrated in FIG. 4A is complementary in shape to chamber 18b and includes a tapered sidewall 132e and an end wall 132f. Sidewall 132e includes an interior surface 132e’ that bounds and defines an interior compartment 132g. Second region 130B of FSA 130 is provided with a single fuze setter adapter induction coil 136 located within interior compartment 132g, adjacent the interior surface 132e’ of sidewall 132e. Fuze setter adapter induction coil 136 is of a type that is compatible with induction coil 20 of LFS 12. Induction coil 136 is capable of electrical power transfer and data/communications with induction coil 20. When second region 130B of FSA 130 is received within chamber 18b, an electrical and communications interface is established between induction coil 20 and induction coil 136 that enables electrical power to be transferred from LFS 12 to FSA 130 and that further enables bidirectional data communication between LFS 12 and FSA 130.

[0105] In accordance with another aspect of the present disclosure, FSA 130 includes a processor control 160 operatively engaged with electrical contacts 134 by wiring 162. Processor control 160 includes a processor, memory, and programming to manage communications and power distribution between NGF 100 and LFS 12. It will be understood that the wiring 162 illustrated herein diagrammatica!ly is representative of the connectivity between processor control 160 and electrical contacts 134. Processor control 160 is also operatively engaged with the single fuze setter adapter induction coil 136 by wiring 164. it will be understood that the wiring 164 illustrated herein diagrammatically is representative of the connectivity between processor control 160 and the induction coil 136. The processor control 160 includes control and electrical power electronics that enable NGF 100 and the LFS 12 to be placed in communication with each other and that further allows the LFS 12 to perform a fuze setting operation on NGF 100. The manner in which processor control 160 connects the electronics of LFS 12 and NGF 100 will be discussed later herein.

[0106] FIG. 4B shows NGF 100 mechanically received within port 132b of FSA 130 and shows second region 130B of FSA 130 mechanically received within chamber 18b of LFS 12. FIG. 4B further shows an electrical power and communications interface formed between contact pads 112 of NGF 100 and electrical contacts 134 of FSA 130. FIG. 4B additionally shows an electrical power and communications interface formed between fuze setter adapter induction coil 136 and legacy fuze setter induction coil 20. The direction arrows“C” in FIG. 4A are provided to show that NGF 100 is selectively inserted into port 132b in FSA 130 and is selectively removed from port 132b. The direction arrows“D” in FIG. 4A are provided to show that second region 130B of FSA 130 is selectively inserted into the chamber 18b of LFS 12 and is selectively removed from chamber 18b.

[0107] FIG. 4C illustrates a retention arm 132h that is pivotally engaged with the housing 132 of FSA 130 by a pivot pin 132j. Retention arm 132h is able to be pivoted in a first direction and into interlocking engagement with a locking member 18e on LFS 12in order to hold FSA 130 in mechanical engagement with LFS 12. Retention arm 132h is able to be pivoted in a second direction and out of engagement with locking member 18e when it is desired to disengage fuze setter adapter 12 from LFS 12. The arrow Έ" is provided to show the selectively pivotal motion of retention arm 132h either toward locking member 18e or away from locking member 18e. It will be understood that retention arm 132h and locking member 18e are exemplary of any type of locking mechanism that may be utilized to hold a fuze setter adapter in engagement with a fuze setter. Although not shown in any of the figures, it will be further understood that a locking mechanism for holding a fuze to fuze setter adapter may also be provided. [0108] FIGS. 5 to 9 show a plurality of different examples of direct connect communications interface type fuzes that are able to be placed in electrical power and data communication with LFS 12 by complementary configured fuze setter adapters in accordance with aspects of the present disclosure. Each fuze setter adapter is designed to have a first region that is compatible and complementary to the fuze in question and to have a second region that is compatible and complementary with the LFS 12. It will be understood that the configurations of the various fuzes and therefore of the first regions of the various fuze setter adapters is exemplary only and should not be construed as limiting the scope of the present disclosure. It will be further understood that the configuration of the processor control and the wiring provided in the various fuze setter adapters and the functioning thereof may vary based on the specific arrangement of electrical contact pads and electrical contacts provided on the fuze and the fuze setter adapter. However, the purpose of the processor control and wiring in the following examples remains the same, i.e., to operatively engage the LFS 12 with the various fuzes.

[0109] FIG. 5 shows a second embodiment of a NGF 200 and a second embodiment of a FSA 230 in accordance with the present disclosure. FSA 230 is capable of operatively engaging NGF 200 with LFS 12.

[0110] FIG. 5 shows only a portion of the nose region of NGF 200. NGF 200 includes a radome housing 204 and a fuze body 206 that are operatively engaged with each other. Radome housing 204 includes an exterior sidewall 204a, a front end 204b, and a rear end 204c. Radome housing 204 defines an interior cavity (not shown) within which various components may be housed. Rear end 204c of radome housing 204 is engaged with front end 206a of fuze body 206.

[0111] A plurality of electrical contacts are provided on an exterior surface of sidewall 204a of radome housing 204. These electrical contacts are in the form of a plurality of longitudinally spaced-apart annular contact rings or bands 212. The contact rings 212 are located a distance longitudinally rearwardly of front end 204b and are operatively engaged with the electronics of NGF 200. Contact rings 212 function in substantially the same manner as contact pads 112.

[0112] FSA 230 has a first region 230A configured to engage with NGF 100 and a second region 230B configured to engage with LFS 12. FSA 230 includes a housing 232 Housing 232 in first region 230A of FSA 230 includes a wall 232a that defines an opening to a port 232b defined by housing 232. In particular, port 232b is bounded and defined by an inwardly extending and tapered sidewall 232c and an end wall 232d. Port 232b is shaped and sized to be complementary to the nose region of NGF 200 and to physically receive the nose region therein.

[0113] The first region 230A of FSA 230 includes a plurality of electrical contacts

234 that are of a substantially identical construction and function as electrical contacts 116, 134 of the aforementioned NGFS 102 and FSA 130, respectively. Electrical contacts 234, however, are positioned differently to electrical contacts 134 in that they are located spaced longitudinally from each other along sidewall 232c. The number and the location of each contact pad 234 is complementary to the number and location of the contact rings 212 on radome housing 204. Each electrical contact 234 is configured to selectively extend into cavity 232b of fuze setter adapter 232. When radome housing 204 is physically received in port 232b, there is direct contact between electrical contacts 234 and contact rings 212 and this results in a high power, low speed interface for efficient electrical power transfer from FSA 230 to NGF 200 and for high speed bi-directional communication between FSA 230 and NGF 200.

The direction arrows“D” in FIG. 8 are provided to show that second region 430B of FSA 430 is selectively inserted into the chamber 18b of LFS 12 and is selectively removed from chamber 18b. Although not illustrated herein, it will be understood that locking mechanisms may be provided to secure FSA 530 to NGF 500 and LFS 12. [0138] FIG. 11 shows a sixth embodiment of a NGF 600 and a fifth embodiment of FSA 630 in accordance with the present disclosure. FSA 630 is capable of operatively engaging NGF 600 with LFS 12.

[0139] FIG. 11 shows only a portion of the nose region of NGF 600. NGF 600 includes a radome housing 604 and a fuze body 606 that are operatively engaged with each other.

[0140] A plurality of grooves 604e are defined in sidewall 604a of radome housing 604. An electrical contact 612 is provided in each groove 604e of radome housing 604. Grooves 604e may extend around the entire circumference of sidewall 604a and if this is the case then electrical contact 612 seated within groove 604e is a substantially continuous contact ring similar to annular contact rings 212 (FIG. 5). In other examples, grooves 604e comprises a plurality of segmented groove sections that are spaced circumferentially from each other. If this is the case, then electrical contacts 612 comprise smaller segments that are substantially similar to electrical contacts 312a, 312b, 312c shown in FIG. 6 but are seated with the spaced-apart groove segments. As illustrated in FIG. 11 , two longitudinally spaced-apart grooves 604e are defined in sidewall 604a of radome housing 604. Consequently, two longitudinal spaced-apart electrical contacts 612 are provided on radome housing 604.

[0142] The first region 630A of FSA 630 includes a plurality of electrical contacts 634 that are of a substantially identical construction and function as electrical contacts 116 of the aforementioned NGFS 102 (FIG. 2). Electrical contacts 634 are configured to selectively extend into cavity 632b of fuze setter adapter and come into direct contact with contact pads 612 and thereby form a direct connect interface that is used for electrical power transfer. In particular, electrical contacts 634 are provided adjacent sidewall 632c in locations that are complementary to the placement of contact pads 612 on NGF 600. When radome housing 604 is physically received in port 632b, there is direct contact between electrical contacts 634 and contact pads 612.

[0149] FIGS. 12A through 12C show a nose region of a seventh embodiment of a next generation fuze, generally indicated at 700 and a LFS 12. The figures also show a sixth embodiment of a FSA 730 that is able to be used to physically and electronically connect NGF 700 and LFS 12 so that a fuze setting operation is able to occur. NGF 700 is an example from US16/294,505 of a next generation fuze that is capable of wireless electrical power transfer and wireless data communications.

[0150] NGF 700 is substantially identical to NGF 100 except for a few features that are discussed further herein.

For this reason, first fuze induction coil 742 may also be referred to herein as a fuze power inductor 742 and the second fuze induction coil 744 may also be referred to herein as a fuze signal inductor 744.

[0152] Fuze power inductor 742 and fuze signal inductor 744 are each configured as an annular inductive coil that is positioned within interior cavity 704d of radome housing 704. Fuze power inductor 742 and fuze signal inductor 744 are located inwardly from and adjacent to the interior circumferential surface 704a’ of sidewall 704a of radome housing 704. No part of fuze power inductor 742 or of fuze signal Inductor 744 extends through sidewall 704a to the exterior surface 704a” thereof. In other words, the exterior surface 704a” of sidewall 704a is substantially continuous and uninterrupted between front wall 704b and rear end 704c. Fuze power inductor 742 and fuze signal inductor 744 are longitudinally spaced a distance apart from each other. Fuze power inductor 742 and fuze signal inductor 744 may be operatively engaged with various appropriate components housed within interior cavity 704d of radome housing 704 or within fuze body 706, such as the previously described fuze power supply and microprocessor.

[0153] It will be understood that either of fuze power inductor 742 and fuze signal inductor 744 may be located closest to front wall 704b and the other of fuze power inductor 742 and fuze signal inductor 744 is then located further away from front wall 704b.

[0154] In one example, fuze power inductor 742 and fuze signal inductor 744 share a common lead, in effect being realized as a single, center-tapped coil, with one tap being used for power transfer and the other for bidirectional communications.

[0155] As is evident from FIG. 12A, this dual coil configuration of NGF 700 is, incompatible with the single induction coil 20 of LFS 12. In accordance with an aspect of the present disclosure, a first embodiment of a FSA 730 is proposed that enables operational engagement between NGF 700 and LFS 12. FSA 730 operatively engages NGF 700 and LFS 12 in such a way that LFS 12 is able to perform a fuze setting operation on NGF 700; i.e., electrical power and communications and data signals are able to be transferred between LFS 12 and NGF 700.

[0156] FSA 730 has a first region 730A configured to engage with NGF 700 and a second region 730B configured to engage with LFS 12. FSA 730 includes a housing 732. The first region 730A of FSA 730 includes a wall 732a that defines an opening to a port 732b defined by housing 732. In particular, port 732b is bounded and defined by an inwardly extending and tapered sidewall 732c and an end wall 732d. Port 732b is shaped and sized to be complementary to the nose region of NGF 700 and to physically receive the nose region therein. [0157] FSA 730 differs from the fuze setter adapters disclosed above in that it does not include any direct connect communications interface type electrical connector regions. Instead, first region 730A of FSA 730 includes a first fuze setter adapter induction coil 746 and a second fuze setter adapter induction coil 748. First fuze setter adapter induction coil 746 is configured to be capable of electrical power transfer. Second fuze setter adapter induction coil 748 is configured to be capable of high speed communications. For these reasons, first fuze setter adapter induction coil 746 may also be referred to herein as fuze setter adapter power inductor 746 and the second fuze setter adapter induction coil 748 may be referred to herein as fuze setter adapter signal inductor 748.

[0158] Fuze setter adapter power inductor 746 and fuze setter adapter signal inductor 748 may each be an annular inductive coil that is positioned outwardly from and adjacent to the interior circumferential surface 732c’ of sidewall 732c of FSA 730. No part of fuze setter adapter power inductor 746 or of fuze setter adapter signal inductor 748 may extend through sidewall 732c to the exterior surface 732c” thereof and into cavity 732c. The exterior surface 732c” of sidewall 732c is therefore free of any obstructions or breaks. Fuze setter adapter power inductor 746 and fuze setter adapter signal inductor 748 may be longitudinally spaced from each other. Fuze setter adapter power inductor 746 is positioned to matingly align with fuze power inductor 742 and fuze setter adapter signal inductor 748 is positioned to matingly align with fuze setter adapter signal inductor 748 when fuze 704 is received in port 732b. Each of fuze setter adapter power inductor 746 and fuze setter adapter signal inductor 748 may be configured as annular coils that will circumscribe fuze power inductor 742 and fuze signal inductor 744, respectively, when radome housing 704 of NGF 700 is inserted into port 732b. It will be understood that if the locations of fuze power inductor 742 and fuze signal inductor 744 are swapped in position relative to what is illustrated in FIG. 12A, then fuze setter adapter power inductor 746 and fuze setter adapter signal inductor 748 will be similarly swapped in position. In one example, fuze setter adapter power inductor 746 and fuze setter adapter signal inductor 748 may share a common lead, in effect being realized as a single, center-tapped coil, with one tap being used for power transfer and the other for bidirectional communications.

[0159] When radome housing 704 is received in port 732b, there is inductive coupling between fuze power inductor 742 and fuze setter adapter power inductor 746 and this results in a high power, low speed interface for efficient electrical power transfer from FSA 730 to NGF 700. Additionally, there is inductive coupling between fuze signal inductor 744 and fuze setter adapter signal inductor 748 and this results in a high speed, lower power coupling for bidirectional data communications between FSA 730 and NGF 700.

[0160] Second region 730B of FSA 730 comprises a connector region that is complementary in shape and size to the chamber 18b defined by LFS 12. The second region 730B is configured to be physically received within chamber 18b. The connector region as illustrated in FIG. 12A includes a tapered sidewall 732e and an end wall 732f. Sidewall 732e includes an interior surface 732e’ that bounds and defines an interior compartment 732g.

[0161] Second region 730B of FSA 730 is provided with a single fuze setter adapter induction coil 736 located within interior compartment 732g, adjacent the interior surface 732e’ of sidewall 732e. Fuze setter adapter induction coil 736 is of a type that is compatible with induction coil 20 of LFS 12. Induction coil 736 is capable of electrical power transfer and data/communications transfer with induction coil 20.

[0162] In accordance with another aspect of the present disclosure, FSA 730 also includes a processor control 760 operatively engaged with fuze setter adapter power inductor 746 and fuze setter adapter signal inductor 748 by wiring 762. It will be understood that the wiring 762 illustrated herein diagrammatically is representative of the connectivity between processor control 760 and the inductors 746, 748. Processor control 760 is also operatively engaged with the single fuze setter adapter induction coil 736 by wiring 764. It will be understood that the wiring 764 illustrated herein diagrammatically is representative of the connectivity between processor control 760 and the inductor 736. The processor control 760 includes control and electrical power electronics that enable NGF 700 and the LFS 12 to be placed in communication with each other and that further allows the LFS 12 to perform a fuze setting operation on NGF 700. The manner in which processor control 760 connects the electronics of LFS 12 and NGF 700 will be discussed later herein.

[0163] FIG. 12B shows NGF 700 mechanically received within port 732b of FSA 730 and second region 730B of FSA 730 mechanically received within chamber 18b of LFS 12. FIG. 12B further shows an electrical power interface formed between fuze power inductor 742 and fuze setter adapter power inductor 746; and a communications interface formed between fuze communications inductor 744 and fuze setter adapter communications inductor 748. FIG. 12B additionally shows a power and communications interface formed between fuze setter adapter induction coil 736 and legacy fuze setter induction coil 20. The direction arrows“C” are provided to show that NGF 700 is selectively inserted into port 732b in FSA 730 and is selectively removed from port 732b. The direction arrows“D" are provided to show that second region 730B of FSA 730 is selectively inserted into the chamber 18b of LFS 12 and is selectively removed from chamber 18b.

[0164] FIG. 12C illustrates a retention arm 732h that is pivotally engaged with the housing 732 of FSA 730 by a pivot pin 732j. Retention arm 732h is able to be pivoted in a first direction and into interlocking engagement with a locking member 18e on LFS 12in order to hold FSA 730 in mechanical engagement with LFS 12. Retention arm 732h is able to be pivoted in a second direction and out of engagement with locking member 18e when it is desired to disengage fuze setter adapter 12 from LFS 12. The arrow Έ” is provided to show the selectively pivotal motion of retention arm 732h either toward locking member 18e or away from locking member 18e. It will be understood that retention arm 732h and locking member 18e are exemplary of any type of locking mechanism that may be utilized to hold a fuze setter adapter in engagement with a fuze setter. Although not shown in any of the figures, it will be further understood that a locking mechanism for holding a fuze to fuze setter adapter may also be provided.

[0165] FIG. 13 is diagrammatic longitudinal section of an eighth embodiment of a NGF 800, a LFS 12, and a seventh embodiment of a FSA 830 in accordance with the present disclosure. FSA 830 is used to operationally engage NGF 800 and LFS 12 with each other.

[0166] NGF 800 is substantially identical to NGF 700 except for a few features that are discussed further herein. NGF 800 includes a radome housing 804 and a fuze body 806 extending rearwardly from radome housing 804. Radome housing 804 includes a sidewall 804a, a front end 804b, and a rear end 804c that bound and define an interior cavity 804d. A front end 806a of fuze body 806 extends rearwardly from rear end 804c of radome housing 804. Although not illustrated herein it will be understood that NGF 800 also includes canards, GPS antennae and various components and sensors as previously discussed. Instead of first and second induction coils 742, 744 that are present in NGF 700, NGF 800 has a single induction coil 844 and an RF transceiver 850. RF transceiver 850 is of a type that communicates wirelessly, e.g. RF transceiver 850 may be a BLUETOOTH ® transceiver. In another example, the RF transceiver 850 may be a custom-built RF transceiver for the specific application of fuze setting utilizing a fuze setter adapter. RF transceiver 850 is used for communications and induction coil 844 is utilized for electrical power transfer. As is evident from FIG. 13, both of the induction coil 844 and the RF transceiver 850 are located adjacent interior surfaces 804a’ of sidewall 804a and 804b’ of front end 804b, respectively. No part of the induction coil 844 or RF transceiver 850 extends through the associated sidewall 804a and front end 804b. By including the wireless interface within the cavity of FSA 830, the interface can be very low power because of the close proximity between transmitter and receiver. Also, the fuze setter adapter may be designed to provide shielding, such that Radio Frequency energy (or optical energy as will be described later herein) is not broadcast into the environment. Each of these elements helps to ensure a high degree of data security and covertness in that little to no energy escapes into the ambient environment where it may be detected.

[0167] FSA 830 has a first region 830A configured to engage with NGF 800 and a second region 830B configured to engage with LFS 12. FSA 830 differs from the fuze setter adapters disclosed above in a number of ways that will be discussed hereafter. FSA 830 includes a housing 832. The first region 830A of FSA 830 includes a wall 832a that defines an opening to a port 832b defined by housing 832. In particular, port 832b is bounded and defined by an inwardly extending and tapered sidewall 832c and an end wall 832d. Port 832b is shaped and sized to be complementary to the nose region of NGF 800 and to physically receive the nose region therein.

[0168] The first region 830A of FSA 830 includes a fuze setter adapter induction coil 848 and an RF transceiver 852 instead of first fuze setter adapter induction coil 746 and a second fuze setter adapter induction coil 748 provided on FSA 730. As is evident from FIG. 13 both of the fuze setter adapter induction coil 848 and RF transceiver 852 are located adjacent an interior surface of sidewall 832c and end wall 832d, respectively, and no part of coil 848 or transceiver 852 extends through the associated sidewall or front wall and into port 832b. Fuze setter adapter induction coil 848 and RF transceiver 852 are configured so as to be capable of transferring electrical power and high speed communications to induction coil 844 and RF transceiver 850, respectively.

[0169] Second region 830B of FSA 830 is substantially identical to second region 730B of FSA 730. Second region 830B of FSA 830 comprises a connector region that is complementary in shape and size to the chamber 18b defined by LFS 12. The second region 830B is configured to be physically received within chamber 18b. The connector region as illustrated in FIG. 13 includes a tapered sidewall 832e and an end wall 832f. Sidewall 832e includes an interior surface 832e’ that bounds and defines an interior compartment 832g. Second region 830B of FSA 830 is provided with a single fuze setter adapter induction coil 836 located within interior compartment 832g, adjacent the interior surface 832e’ of sidewall 832e. Fuze setter adapter induction coil 836 is of a type that is compatible with induction coil 20 of LFS 12. Induction coil 836 is capable of electrical power transfer and data/communications transfer with induction coil 20.

[0170] Fuze setter adapter induction coil 848 and RF transceiver 852 are connected to a processor control 860 by wiring 862.

The processor control 860 includes control and electrical power electronics that enable NGF 800 and the LFS 12 to be placed in communication with each other and that further allows the LFS 12 to perform a fuze setting operation on NGF 800. Processor control 860 is substantially identical to processor control 760 except in any aspects for the control and functioning of RF transceiver 852. The manner in which processor control 860 connects the electronics of LFS 12 and NGF 800 will be discussed later herein.

[0171] The arrows“C” shows that NGF 800 may be physically introduced into port 832b for fuze setting and may be removed therefrom once fuze setting is completed. The arrows“D” shows that FSA 830 may be physically introduced into chamber 18b of legacy fuze 18 for fuze setting and may be removed therefrom once fuze setting is completed. Although not illustrated herein, it will be understood that locking mechanisms may be provided to secure FSA 830 to NGF 800 and LFS 12.

A front end 906a of fuze body 906 extends rearwardly from rear end 904c of radome housing 904. Although not illustrated herein it will be understood that NGF 900 also includes canards, GPS antennae and various components and sensors as previously discussed.

[0174] NGF 900 has a single induction coil 944 and a Height of Burst (HoB) sensor 954 instead of RF transceiver 850 or a second induction coil. HoB sensor 954 is a Height of Burst sensor that has transmitting and receiving capability (i.e. , T_x/R_x capability). HoB sensor 954 is used for communications and induction coil 944 is utilized for electrical power transfer.

In particular, port 932b is bounded and defined by an inwardly extending and tapered sidewall 932c and an end wall 932d. Port 932b is shaped and sized to be complementary to the nose region of NGF 900 and to physically receive the nose region therein. FSA 930 is substantially identical to FSA 830 in that first region 930A includes a fuze setter adapter induction coil 948 and an RF transceiver 952. As is evident from FIG. 14 both of the fuze setter adapter induction coil 948 and RF transceiver 952 are located adjacent an interior surface of sidewall 932c and end wall 932d, respectively, and no part of coil 948 or transceiver 952 extends through the associated sidewall or front wall and into port 932b. Fuze setter adapter induction coil 948 and RF transceiver 952 are configured so as to be capable of transferring electrical power and high speed communications to induction coil 944 and to HoB sensor 954, respectively.

Second region 930B of FSA 930 comprises a connector region that is complementary in shape and size to the chamber 18b defined by LFS 12. The second region 930B is configured to be physically received within chamber 18b. The connector region as illustrated in FIG. 14 includes a tapered sidewall 932e and an end wall 932f.

The manner in which processor control 960 connects the electronics of LFS 12 and NGF 900 will be discussed later herein.

[0178] The arrows“C” shows that NGF 900 may be physically introduced into port 932b for fuze setting and may be removed therefrom once fuze setting is completed. The arrows“D” shows that FSA 930 may be physically introduced into chamber 18b of legacy fuze 18 for fuze setting and may be removed therefrom once fuze setting is completed. Although not illustrated herein, it will be understood that locking mechanisms may be provided to secure FSA 930 to NGF 900 and LFS 12. [0179] FIGS. 15A and 15B are diagrammatic longitudinal section views of a tenth embodiment of a NGF 1000, a LFS 12, and a tenth embodiment of a FSA 1030 in accordance with the present disclosure. FSA 1030 is used to operationally engage NGF 1000 and LFS 12 with each other.

[0187] FIG. 16A is a diagrammatic longitudinal section view of an exemplary NGF 100V, a LFS 12, and an eleventh embodiment of a FSA 1 130V in accordance with the present disclosure. NGF 100V includes a direct connect interface for both communications and electrical power transfer.

In other examples, a connector port may be utilized. NGF 100V is either internally powered (e.g. has an internal battery) or is powered via a secondary external source.

[0188] FSA 1130V differs from all embodiments of fuze setter adapter disclosed herein in that it does not include a first region that is configured to receive a nose region of NGF 100V therein. FSA 1130V does, however, include a second region 1130B that is configured to mate with LFS 12. FSA 1130V includes a housing 1132 that has a front wall 1132a but no port is defined in front wall 1132.

[0189] A processor control 1160V is provided in FSA 1130V. Processor control 1160V is operatively engaged with electrical connector region 1166 by wiring 1 162. Processor control 1160V is operatively engaged with fuze setter adapter induction coil 1136 by wiring 1164. The processor control 1160V includes control electronics that enable NGF 100V and the LFS 12 to be placed in communication with each other and that further allows the LFS 12 to perform a fuze setting operation on NGF 100V. The manner in which processor control 1 160V connects the electronics of LFS 12 and NGF 100V will be discussed later herein.

[0190] The arrows“D” shows that FSA 1130V may be physically introduced into chamber 18b of legacy fuze 18 for fuze setting and may be removed therefrom once fuze setting is completed. Although not illustrated herein, it will be understood that locking mechanisms may be provided to secure FSA 1130V to NGF 100V and LFS 12.

[0191] FIG. 16B is a diagrammatic longitudinal section view of an exemplary NGF 100W, a LFS 12, and a twelfth embodiment of a FSA 1130W in accordance with the present disclosure. NGF 100W includes a wireless interface for both communications and electrical power transfer. In this particular instance, the wireless interface is illustrated as an optical transceiver 156. Optical transceiver 156 is located within the interior of NGF 100W and adjacent a transparent window 103 through which optical signals are able to be transmitted or received. NGF 100W includes an internal power source 101 , such as a battery. The power source 101 is provided because sufficient electrical power to operate NGF 100W may not be able to be transferred over the wireless interface. NGF 100W therefore has the separate source of electrical power 101 and will include a power switch of some type (not shown) to turn the NGF 100W on so that it can function and establish communication with FSA 1130W. NGF 100W may be placed at some distance from FSA 1130W, anticipated to be somewhere from about 1 m up to about 10m away. It will be understood that instead of an optical transceiver 156 in NGF 100W, an RF transceiver may be utilized and window 103 may be omitted from NGF 100W. It will further be understood that the wireless interface, whether an optical transceiver or a RF transceiver, may be located anywhere on NGF 100W. Utilizing these types of wireless interface may result in data being broadcast into the environment. Thus, encrypted communications or some other form of security would need to be implemented.

[0192] FSA 1130W is substantially similar to FSA 1130V in that it does not include a first region configured to receive a nose region of NGF 100W therein. FSA 1130W does, however, include a second region 1130B that is configured to mate with LFS 12. FSA 1130W includes a housing 1132 that has a front wall 1132a’ but no port is defined in front wall 1132.

Induction coil 1136 is capable of electrical power transfer and data/communications transfer with induction coil 20. An optical transceiver 1058 is provided adjacent front wall 1132a’ of FSA 1130W. Optical transceiver 1058 is provided to communicate with optical transceiver 1056 on NGF 100W. While FIG. 16B shows optical transceiver 1058 located on the outside surface of wall 1132a’, in other instances, the optical transceiver is located adjacent an interior of wall 1132a’, with the optical energy passing through a transparent window provided in wall 1132a’, similar to the optical interface described in FIGS. 15A and 15B. It will be understood that if an RF transceiver is provided on NGF 100W, then an RF transceiver will be provided on FSA 1130W to communicate with the RF transceiver on NGF 100W. An RF transceiver on FSA 1130W (or at least the antenna portion thereof) may be located on the exterior surface of wall 1132a’ or it may be located within the housing and behind wall 1132a’, with at least a portion of wall 1132a’ being transparent to RF energy.

The manner in which processor control 1160V connects the electronics of LFS 12 and NGF 100W will be discussed later herein.

[0194] The arrows“D” shows that FSA 1130W may be physically introduced into chamber 18b of legacy fuze 18 for fuze setting and may be removed therefrom once fuze setting is completed. Although not illustrated herein, it will be understood that locking mechanisms may be provided to secure FSA 1130W to NGF 100W and LFS 12.

Although not illustrated herein, it will be understood that locking mechanisms may be provided to secure FSA 1530 to legacy fuze 10, and NGFS 102. [0227] FIG. 19 discloses a twenty fourth embodiment of a fuze setter adapter in accordance with the present disclosure that enables engagement between an incompatible fuze and fuze setter. In this example, the incompatibility stems from a radome housing on the fuze that is not of a compatible complementary shape and/or size to the port provided on the fuze setter. FIG. 19 shows an exemplary NGF 1600 having a relatively elongated radome housing 1604 with a shallow taper angle. The exemplary fuze setter 1602, on the other hand, defines a relatively short port 1614 having a steeper taper angle. When radome housing 1604 is introduced into port 1614 electrical power transfer and/or data communications may not be possible because contact pads, electrical contacts, induction coils, RF transceivers, HoB sensors, or optical transceivers on the two devices may not be able to establish communication with each other. A FSA 1630 is provided with a first region 1630A that defines a port 1632b therein that is complementary in shape and size to the radome housing 1604 on NGF 1600. FSA 1630 is also provided with a second region 1630B that is complementary in shape and size to the chamber 1614b defined in fuze setter 1602. The fuze and fuze setter in this example are presumed to have components for electrical power transfer and data communications that would typically be able to communicate with each other. However, in other examples, in addition to providing a port 1632b and a connector region 1632e, 1632f, that are complementary to the shapes of radome housing 1604 of NGF 1600 and chamber 1614 of fuze setter 1602, FSA 1630 may provide compatible components for electrical power transfer and data communications between NGF 1600 and fuze setter 1602.

[0228] It should be understood that each of the processor controls 160, 260, 360, 460, 560, 660, 760, 860, 960, 1060, 1160V, 1160W, 1260, 1360, 1460, and 1560 includes a processor with memory that is used for data buffering. In other words, the data is able to be received by the processor from one of the fuze setter and fuze at one rate and is able to be transmitted to the other of the fuze setter and fuze at a different rate. Similarly, with respect to data format, data may be received at the processor from the fuze setter in one format and then retransmitted to the fuze in a different format, and vice versa.

[0229] FIG. 20 is a flowchart depicting the operation of a direct connect next generation fuze, a legacy inductive fuze setter, and a fuze setter adapter that operationally engages the fuze and legacy fuze setter and enables them to communicate with each other. The flowchart is applicable to all of the embodiments of direct connect next generation fuzes and the complementary fuze setter adapters disclosed herein. However, in order to more clearly explain the operation of this system, the direct connect NGF 100, LFS 12, and FSA 130 are reference in the flowchart.

[0230] The operation of FSA 130 regarding electrical power and data transfer from LFS 12 to NGF 100 includes the following. LFS 12 includes a processor control 21 that controls all relevant aspects of timing, signal condition, timing, and data encoding and decoding across the inductive interface 20. Processor control 21 is also used to arbitrate whether and when power or data is transferred over inductive interface 20 and in what direction (i.e. , whether the data is being transmitted to NGF 100 or received from NGF 100). LFS 12 encodes fuze data 23 onto appropriate waveforms 25 to transmit to NGF 100. LFS 12 also transfers electrical power onto appropriate waveforms 27 to transmit to NGF 100. The encoded fuze data waveform 25 and electrical power waveform 27 are combined into a power/data waveform 29. In a next step 31 , the waveform 29 is used to drive fuze setter inductive coil 20. The waveform 29 is detected in FSA 130 via inductive coupling between the FSA inductive interface 136 and the LFS inductive interface 20 when the FSA 130 is mated to the LFS 12.

[0231] Processor control 160 in FSA 130 is used to control all relevant aspects of timing, signal conditioning, timing, and data encoding and decoding across the inductive interface 136 and direct contact interface 134 of FSA 130. It should be noted that processor control 160 includes a memory 161 that is used for data buffering. This allows data to be received from LFS 12 at one rate and to be transmitted to NGF 100 at another rate, and vice versa. Data buffering also allows data to be received from the LFS 12 in one format and transmitted to NGF 100 in a different format, and vice versa. FSA 130 decodes the power and transmitted data waveform 137. FSA 130 applies power 139 and data signals 141 to appropriate contact pins on the fuze direct connect interface 134, 112. NGF 100 receives the power 113 and data 115 transferred by FSA 130.

[0232] The operation of FSA 130 regarding data transfer from NGF 100 to the LFS 12 includes the following. The processor control 160 in FSA 130 is used to control all relevant aspects of timing, signal condition, timing, and data encoding and decoding across the inductive interface 136 and direct contact interface 134 of FSA 130. NGF 100 is powered by the power 113 received from the LFS 12 via FSA 130. NGF 100 transmits data to FSA 130 via the direct connect interface 112, 134. The processor

160 in FSA 130 reads the data (i.e. the received data from the fuze) and buffer memory

161 may be used to buffer (temporarily store) the incoming data, allowing the processor 160 to reformat the data into a format compatible with the FSA 130. The reformatted data is then re-encoded onto a waveform 143 in a format suitable for transmitting via the inductive interface 136, 20. Encoded data is received by the LFS 12 via the inductive interface element 136 of FSA 130. The fuze setter processor 21 reads the received data 33 and extracts the received data (Rx data) 35 from the received waveform 143.

[0233] FIG. 21 is a flowchart depicting the operation of a direct connect next generation fuze setter, a legacy fuze, and a fuze setter adapter that operationally engages the fuze setter and legacy fuze to each other. By way of example only, the selected next generation fuze setter is direct connect NGFS 102 (FIG. 2, also shown as 1202V in FIG. 17A), LF 10 and FSA 1230V. The flowchart is, however, applicable to any of the embodiments of the next generation fuzes and the complementary fuze setter adapters disclosed herein.

[0234] The operation of FSA 1230V with respect to electrical power and data transfer from NGFS 102 to LF 10 comprises the following. The processor control 131 in NGFS 102 is used to control all relevant aspects of timing signal conditioning, timing and data encoding and decoding across direct connect interface 116. It is also used to arbitrate whether and when power or data is transferred over the direct connect interface 116 and in what direction (i.e., transmit or receive). NGFS 102 transfers electrical power 133 and fuze data 135 to FSA 1230V via the direct connect interface 116 to the corresponding direct connect interface 1270 within FSA 1230V. The processor control 1260 in FSA 1230V is used to control all relevant aspects of timing, signal conditioning, timing and data encoding and decoding across the inductive and direct connect interfaces of FSA 1230V. Processor control 1260 includes memory 1261 that can be used for data buffering and so that data received at one rate from NGFS 102 can be transmitted to LF 10 at another rate, and vice versa. Data may also be received from the NGFS 102 in one format and then is retransmitted to the LF10 in a different format, and vice versa. FSA 1230V combines and encodes power and data to be transferred to the LF 10 into an appropriate waveform 1271. The waveform 1271 is used to drive 1273 the fuze inductive coil 1236 of the fuze setter adapter inductive interface. The waveform is detected and read 51 by the LF 10 via inductive coupling across the inductive interface 16. The LF 10 extracts electrical power 53 and extracts and decodes 55 the transmitted data waveform (i.e., T_x data).

[0235] The operation of FSA 1230V with respect to data transfer from the LF 10 to NGFS 102 includes the following. The processor control 1260 in FSA 1230V is used to control all relevant aspects of timing, signal condition, timing and data encoding and decoding across the inductive interface 1236 and direct contact interface 1270 of FSA 1230V. The LF 10 is powered by the power 53 received from NGFS 102 via FSA 1230V. The LF 10 encodes data 57 to be transferred to the fuze setter (R_x data) by encoding in appropriate waveform 59 and which drives 61 the inductive coil 16 and transmits the waveform 59 to FSA 1230V via the inductive interface 16, 1236. FSA 1230V reads the inductive coil 1275 and decodes the received data (Rx data) 1277 transferred by the LF 10. The received data (Rx data) 1277 is then transferred to NGFS 102 via the direct connect interface 1270, 116.

[0236] It will be understood that the methodologies of operation shown in FIGS. 20 and 21 are applicable to any of the fuzes, fuze setters, and fuze setter adapters disclosed herein. The type of interfaces through which the fuzes, fuze setters, and fuze setter adapters communicate with each other changes as does the wiring that connects the interfaces to the associated processor control and the programming in the processor control.

[0237] As indicated above, the flowcharts illustrated in FIGS. 20 and 21 describe the operation of fuze setter adapters for converting the inductive interface of a legacy fuze setter to a direct-connect electrical interface on a fuze, and vice versa. As a general concept (see FIG. 22), the fuze setter adapters serve as intermediary devices which allow a fuze setter to communicate with a fuze where the interfaces of the fuze setter and the fuze are incompatible. Interface incompatibility may include any or all of a mechanical interface, an electrical interface, a communications interface, and/or an electrical power interface. There is no fundamental constraint that either interface needs to be inductively coupled. [0238] The fuze setter adapter is an active adapter that provides the ability to accept, store, buffer, translate and communicate data between the two adapter regions that are coupled to otherwise incompatible fuze and fuze setter. The fuze setter adapter may be powered directly from the fuze setter or from an external host, and may also communicate with an external host. In some cases, the fuze may be powered by an internal battery and therefore would not require power from the fuze setter. In this case, the adapter would only need to support communications between fuze and fuze setter.

[0239] FIG. 22 is a flowchart depicting the operation of a generalized or universal FSA 1830 that is utilized to operationally engage and incompatible fuze 1800 and fuze setter 1812 with each other. The flowchart illustrates the exemplary FSA 1830 in accordance with the present disclosure that is configured to mate with each of fuze 1800 and fuze setter 1812. FSA 1830 is further configured to communicate with each of fuze 1800 and fuze setter 1830 and to thereby establish connection between the communications and electrical power interfaces of fuze 1800 and fuze setter 1812 that enables a fuze setting operation to occur. FSA 1830 is an active adapter that provides all interface translations and conversions necessary to allow communications and electrical power transfer between fuze 1800 and an otherwise incompatible fuze setter 1812.

[0240] Fuze 1800 includes a mechanical interface 1801 , an electrical signal interface 1803, an electrical power interface 1805, and a communications interface 1807. Fuze setter 1812 includes a mechanical interface 1813, an electrical signal interface 1815, an electrical power interface 1817, and a communications interface 1819.

[0241] FSA 1830 provides mechanical interfaces 1831 , 1833. The first mechanical interface 1831 is compatible with mechanical interface 1801 of fuze 1800. The second mechanical interface 1832 is compatible with mechanical interface 1813 of fuze setter 1812.

[0242] FSA 1830 provides electrical signal interfaces 1835, 1837. These interfaces provide the ability to communicate information between fuze 1800 and fuze setter 1812 via discrete electrical signals. The first electrical signal interface 1835 is compatible with electrical signal interface 1803 of fuze 1800 and the second electrical signal interface 1837 is compatible with electrical signal interface 1815 of fuze setter 1812. Signal conversion electronics 1863 within FSA 1830 convert a set of electrical signals from the fuze setter 1812 to a corresponding set of electronics compatible with fuze 1800, and vice versa.

[0243] FSA 1830 additionally provides electrical power interfaces 1839, 1841 and electrical power conversion functions 1867 between fuze setter 1812 and fuze 1800. A first of these electrical power interfaces 1839 is compatible with electrical power interface 1805 of fuze 1800 and the second electrical power interface 1841 is compatible with electrical power interface 1817 of fuze setter 1812. Power conversion electronics 1867 within FSA 1830 convert input power from fuze setter 1812 into a form compatible with fuze 1800 and provide that converted power to the fuze interface 1805.

[0244] The communications interface of FSA 1830 also provides communication interfaces 1843, 1845 and communication translation 1869 between fuze setter 1812 and fuze 1800. A first communications interface 1843 is compatible with the communications interface 1807 of fuze and the second communications interface 1845 is compatible with the communications interface 1819 of fuze setter 1812. Translation includes, for example, any message format, data rate, data content, and data format conversions that may be necessary to allow compatible communications between fuze 1800 and fuze setter 1812. In other words, translation includes any elements that will allow communication between a fuze setter and an incompatible fuze. The translation software utilized for translation is the software resident in FSA 1830 that serves to translate messages and data received by a first of the two communications interfaces 1843, 1845 into a format compatible with communication with a second of the two communications interfaces provided by FSA 1830, and vice versa.

[0245] FSA 1830 can include interfaces to an external host 1900. The interfaces can include an external host electrical power interface 1847 and an external host communications interface 1849. The electrical power interface 1847 may be used to extract power from the host 1900 that can be used to power the FSA 1830, fuze setter 1812, and/or fuze 1800. The communications interface 1847 may be used for host-to- fuze setter adapter communications, and for host-to-fuze setter and/or host-to-fuze communications via FSA 1830. Communications interface 1847 may receive communications and data signals from the external host 1900 or may transmit communications and data signals to the external host 1900. Connecting FSA 1830 to external host 1900 such as a remote computer) will allow fuze setting and other operations to be monitored and controlled via the host 1900.

[0246] FSA 1830 includes a processor control 1860 having a memory 1861. Processor control 1860 is connected to all of the internal functional blocks of FSA 1830 as necessary, i.e., with the mechanical interfaces 1831 , 1833; the electrical signal interfaces 1835, 1837; the electrical power interfaces 1839, 1841; and the communications interfaces 1843, 1845. Processor control 1860 is also connected to communications interface 1849 and electrical power interface 1847 that are selectively operatively engaged with remote external host 1900. Processor control 1860 includes programming that operatively engages the systems of fuze and fuze setter with each other and enables fuze setting to occur. It will be understood that each of the processor controls disclosed herein perform substantially the same function in the fuze setter adapters within which they are located.

[0247] Processor control 1860 is capable of electrical signal conversion 1863. In other words processor control 1860 is able to take an electrical signal received by interface 1837 of FSA 1830 from electrical signal interface 1815 of fuze setter 1812 and, using the electrical signal conversion function 1863 of processor control 1860, convert that electrical signal to one compatible for electrical signal interface 1803 of fuze 1800. Processor control 1860 then sends the converted electrical signal to electrical signal interface 1803 of fuze 1800 via electrical signal interface 1835 of FSA 1830. The reverse situation is also true in that processor control 1860 is able to take an electrical signal received by electrical signal interface 1835 of FSA 1830 from electrical signal interface 1803 of NGF 200 and, using the electrical signal conversion function 1863 of processor control 1860, convert that electrical signal to one compatible for electrical signal interface 1817 of fuze setter 1812. Processor control 1860 then sends the converted electrical signal to electrical signal interface 1817 of fuze setter 1812 via electrical signal interface 1837 of FSA 1830.

[0248] Processor control 1860 is capable of performing an electrical power conversion 1865. In other words, processor control 1860 is able to take electrical power received by electrical power interface 1841 of FSA 1830 from electrical power interface 1817 of fuze setter 1812 and, using the electrical power conversion function 1865 of processor control 1860, convert that electrical power to a power signal that is compatible with electrical power interface 1805 of fuze 1800. Processor control 1860 then sends the converted electrical power signal to electrical power interface 1805 of fuze 1800 via electrical power interface 1839 of FSA 1830. The reverse situation is also true in that processor control 1860 is able to take electrical power received by electrical power interface 1839 of FSA 1830 from electrical power interface 1805 of fuze 1800 and, using the electrical power conversion function 1865 of processor control 1860, convert that electrical power to a power signal that is compatible with electrical power interface 1817 of fuze setter 1812. Processor control 1860 then sends the converted electrical power signal to electrical power interface 1817 of fuze setter 1812 via electrical power interface 1841 of FSA 1830.

[0249] Processor control 1860 is also capable of performing a communications conversion function and/or a communications translation function. Processor control 1860 also has memory that enables data buffering 1869. In other words, processor control 1860 is able to take communications or data received by communications interface 1845 from communications interface 1819 of fuze setter 1812 and, using the communication conversion/translation/data buffering function 1869 of processor control 1860, convert the communications or data signal to one compatible for communications interface 1807 of fuze 1800. Processor control 1860 will then send the converted communications signal from communications interface 1843 of FSA 1830 to communications interface 1807 of fuze 1800. Bidirectional communication is also possible in some instances. In these instances, communications or data signals from communications interface 1807 of fuze 1800 may be received by communications interface 1843 of FSA 1830 and converted by the communications conversion/translation/data buffering function 1869 of processor control 1860 to a signal compatible with communications interface 1819 of fuze setter 1812. That converted communications or data signal is sent to communications interface 1819 of fuze setter 1812 via communications interface 1845 of FSA 1830. In either instance, memory 1861 of processor control 1860 can be used for data buffering. This arrangement allows data to be received at one rate from communications interface 1807, for example, and is able to be transmitted at a different rate to communications interface 1819, and vice versa.

[0250] FIGS. 23A through 23C provide examples of fuze setter adapters that are utilized to enable multiple fuzes and/or fuze setters to be engaged with each other. FIG. 23A shows a twenty-fifth embodiment FSA 2130 in accordance with the present disclosure. FSA 2130 incudes a first region 2130A configured to engage with a fuze and a second region 2130B configured to engage with a fuze setter.

Each of the ports 2132b, 2132b’, and 2132b”, as well as induction coil 2136 is operatively engaged by wiring (not shown) to processor control 2160. (It will be understood that while a single processor control 2160 is illustrated, more than one processor control may be provided in FSA 2130 to control different interfaces.) FSA 2130 is therefore able to be utilized as a type of“universal” fuze setter adapter that can be taken into the field and used to perform fuze setting operations on a variety of different munitions. The port selected for use will be based on the particular fuze that needs to be programmed.

[0251] As illustrated by way of example only, second region 2130B of FSA 2130 is configured to be engaged with LFS 12 (FIG. 1). It will be understood, however, that any of the configurations of second regions of the fuze setter adapters disclosed in this specification may be utilized, or any other differently configured second region may be provided on FSA 2130. [0252] It should be understood that although the various ports 2132b, 2132b’, and 2132b” are shown in FIG. 23A as all being enclosed within a single housing, in another embodiment, one or more of the ports 2132b, 2132b’ and 2132b” may comprise separate components that are located outside of the housing and are connected thereto by way of a suitable electrical cable. FSA 2130 will therefore comprise a central housing containing at least the processor 2160 plus one or more electrical cables connected to the processor 2160 and extending outwardly from the housing, and terminating in one of the various port configurations. It will be understood that in one exemplary embodiment, the connector region 2130B may additionally or alternatively form part of a separate component that is connected by a suitable electrical cable to processor 2160, where the cable extends outwardly from the housing and terminates in the separate connector region component.

[0253] FIG. 23B shows a twenty-sixth embodiment FSA 2230 in accordance with the present disclosure. FSA 2230 incudes a first region 2230A configured to engage with a fuze and a second region configured to engage with a fuze setter. FSA 2230 includes a housing that defines a single port for engaging a fuze. Port 2232b is configured to include two induction coils 2248, 2246 suitable for communication with NGF 700 (FIG. 12A). Three exemplary connector regions 2230B, 2230B’, and 2230B” are provided on FSA 2230. Each of the connector regions is configured to be able to engage a different type of fuze setter. The first connector region 2230B is illustrated as including an induction coil 2236 arranged in such a manner as to be suitable for communication with LFS 12 (FIG. 1). The second connector region 2230B’ is illustrated as including a plurality of contact pads 2270 arranged in such a manner as to be suitable for communication with FS 1202V (FIG. 17A).

Each of the connector regions 2230B, 2230B’, and 2230B”, as well as induction coils 2246 and 2248 are operatively engaged by wiring (not shown) to processor control 2260. (It will be understood that while a single processor control 2260 is illustrated, more than one processor control may be provided in FSA 2230 to control different interfaces.) FSA 2230 is therefore able to be utilized as a type of“universal” fuze setter adapter that can be taken into the field and used to perform fuze setting operations on one type of fuze using an appropriate one of a variety of different fuze setters. The connector region selected for use will be based on the particular fuze setter that is available to perform fuze setting.

It will further be understood that any of the configurations of the connector regions disclosed in this specification or any other desired configuration of the connector region, may be utilized in FSA 2230. The one direct connect connector region (2230B’) and the two wireless connector regions (2230B and 2230B”) illustrated herein are exemplary only.

[0255] As illustrated by way of example only, first region 2230A of FSA 2230 is configured to be engaged with NGS 100 (FIG. 4A). It will be understood, however, that any of the configurations of first regions of the fuze setter adapters disclosed in this specification may be utilized, or any other differently configured first region may be provided on FSA 2230.

[0256] It should be understood that although the various connector regions 2230B, 2230B’, and 2230B” are shown in FIG. 23B as all being enclosed within a single housing, in another embodiment, one or more of the connector regions may comprise separate components that are located outside of the housing and are connected thereto by way of a suitable electrical cable. FSA 2230 will therefore comprise a central housing containing at least the processor 2260 plus one or more electrical cables connected to the processor 2260 and extending outwardly from the housing, and terminating in one of the various connector region configurations. It will be understood that in one exemplary embodiment, the port 2232b may additionally or alternatively form part of a separate component that is connected by a suitable electrical cable to processor 2260, where the cable extends outwardly from the housing and terminates in the separate connector region component.

[0257] FIG. 23C shows a twenty-seventh FSA 2330 in accordance with the present disclosure. FSA 2330 incudes a first region 2330A configured to engage with various fuzes and a second region configured to engage with various fuze setters. FSA 2330 includes a housing that defines multiple ports 2332b, 2332b’ and 2332b” for engaging different fuzes. Ports 2332b, 2332b’, and 2332b” are substantially identical to ports 2132b, 2132b’, and 2132b” and are used for the same purpose. FSA 2330 also multiple exemplary connector regions 2330B, 2330B’, and 2330B”. Connector regions 2330B, 2330B’ and 2330B” are substantial identical to connector regions 2230B, 2230B’, and 2230B” and are used for the same purpose. All of the ports 2332b, 2332b’, and 2332b” and all of the connector regions 2330B, 2330B’, and 2330B” are operatively engaged with processor control 2360 (or with multiple processor controls) via wiring that is not illustrated.

[0258] FSA 2330 is able to be utilized as a type of“universal” fuze setter adapter that can be taken into the field and used to perform fuze setting operations on multiple different types of fuzes using an appropriate one of any of a variety of different fuze setters provided on FSA 2330. The port or connector region selected for use will be based on the particular fuze or particular fuze setter that is available.

[0259] It will be understood that any number of ports and connector regions may be provided on FSA 2330 to engage with any desired number of different fuzes and fuze setters. It will further be understood that any of the configurations of the ports and/or connector regions disclosed in this specification or any other desired configuration of ports and connector regions, may be utilized in FSA 2330. The illustrated ports and connector regions are exemplary only.

[0260] It should be understood that although the various ports 2332b, 2332b’, and 2332b” and connector regions 2330B, 2330B’, and 2330B” are shown in FIG. 23C as all being enclosed within a single housing, in another embodiment, one or more of the ports 2332b, 2332b’ and 2332b” and/or one or more of the connector regions 2330B, 2330B’, and 2330B” may comprise separate components that are located outside of the housing and are connected thereto by way of a suitable electrical cable. FSA 2330 will therefore comprise a central housing containing at least the processor 2360 plus one or more electrical cables connected to the processor 2360 and extending outwardly from the housing, and terminating in one of the various port configurations or one of the various connector region configurations.

[0261] Referring to FIG. 24 there is shown a flowchart of an exemplary method 4000 of utilizing a fuze setting system comprising a NGF 3000, an incompatible fuze setter 3012 (hereafter FS 3012), and a FSA 3030 to perform a fuze setting operation.

It should be noted that this flowchart is simplified. In practice, there would be a lot of detailed interaction between NGF 3000, FSA 3030, and FS 3012. For example, most actions taken would include a validity check to ensure that each action requested was executed successfully, e.g. communications were established, data was received and transferred successfully etc. This type of action has been omitted from the figure. Additionally, every one of the aforementioned checks anticipates the possibility of a fault or failure. Specific actions, also not shown in this figure, would be taken in the event of a fault or failure condition. Similarly, the figure shows things happening in a sequence. However, in practice, based on the design, certain activities may happen concurrently, e.g. electrical power and data conversion may occur concurrently.

[0262] As illustrated in the figure, a first step 3001 involves connecting FSA 3030 to NGF 3000 and FS 3012. This is accomplished by attaching FS 3012 to FSA 3030 as indicated by arrow 3002 and attaching FSA 3030 to NGF 3000 as indicated by arrow 3003.

[0263] In a second step 3004, electrical power is applied and the fuze setter adapter processor (in the processor control) and the fuze processor (not shown) will boot up and initialize. This is accomplished by applying electrical power to FSA 3030 indicated by arrow 3005. The fuze setter adapter processor boots up as indicated by arrow 3006. FSA 3030 generates fuze-compatible electric power, indicated by arrow 3007. FSA 3030 applies electrical power to NGF 3000, indicated by arrow 3008, and the fuze processor boots up 3009. (FSA 3030 will apply electrical power to NGF 3000 via the electrical power interfaces provided on FSA 3030 and NGF 3000.)

[0264] In a third step 3010, communications between FS 3012, FSA 3030, and NGF 3000 are established. This is accomplished by establishing communications between FS 3012 and FSA 3030, indicated by arrow 3011 , and the FSA 3030 reporting back to the FS 3012 verification that fuze setter-to-fuze setter adapter communications have been established, as indicated by arrow 3013. The third step also includes establishing communications between FSA 3030 and NGF 3000, indicated by arrow 3014, and reporting confirmation that fuze setter adapter-to-fuze communication has been established, indicated by arrow 3015.

[0265] In a fourth step 3016, the FS 3012 checks the status of FSA 3030 and NGF 3000, and verifies they are good to go. This is accomplished by the FS 3012 requesting the fuze setter adapter status, indicated by arrow 3017, and the fuze setter adapter reporting its status, indicated by arrow 3018. The FS 3012 then requests the fuze status, indicated by arrow 3019, which causes FSA 3030 to request the fuze status 3020. in other words, the request for fuze status is transferred from the FS 3012 to NGF 3000 via FSA 3030. NGF 3000 reports the fuze status, indicated by arrow 3022, and the fuze setter adapter reports the fuze status to the fuze setter, indicated by arrow 3023. In other words, the fuze status report is transferred from NGF 3000 to the FS 3012 via FSA 3030.

[0266] In a fifth step 3024, fuze setting data is transferred from the FS 3012 to FSA 3030 and then from FSA 3030 to NGF 3000. NGF 3000 reports its Data Received status back to the fuze 3012 via FSA 3030. It will be understood that the data in question may be any type of data but generally will fall into one of two major categories. The data could be fuze setting data that needs to be programmed into NGF 3000 prior to launch of the projectile with which fuze is engaged, or it could be new software/firmware load for reprogramming NGF 3000. The FS 3012 transfers fuze data to FSA 3030, indicated by arrow 3025. FSA 3030 decodes data from FS 3012 and stores the decoded data in memory of the processor control in FSA 3030, indicated by arrow 3026. FSA 3030 reads data from memory and encodes it in fuze-compatible format, indicated by arrow 3027 and then transfers fuze data to NGF 3000, indicated by arrow 2028. NGF 3000 processes and stores received data as necessary, indicated by arrow 3029. NGF 3000 reports data received status to FSA 3030, indicated by arrow 3031. The FSA 3030 reports fuze data received status to FS 3012, indicated by arrow 3032.

[0267] In a sixth step 3033, FS 3012 sends a discrete electrical signal to NGF 3000 via FSA 3030. This is accomplished by FS 3012 sending a discrete electrical signal to FSA 3030, indicated by arrow 3034. FSA 3030 converts the fuze setter discrete electrical signal to fuze-compatible format, indicated by ano^N 3035, and sends the converted fuze setter discrete electrical signal to NGF 3000, indicated by arrow 3036. It will be understood that in practice, there may be more than one discrete electrical signal, with each of the more than one discrete electrical signals operating independently.

[0268] In a seventh step 3037, the FS 3012 receives a discrete electrical signal from NGF 3000 via FSA 3030. This is accomplished by NGF 3000 sending a fuze discrete electrical signal to FSA 3030, indicated by arrow 3038. FSA 3030 converts the fuze discrete electrical signal to a fuze setter-compatible format, indicated by arrow 3039. FSA 3030 then sends the converted fuze discrete electrical signal to FS 3012, indicated by arrow 3040. It will be understood that in practice, there may be more than one discrete electrical signal, with each of the more than one discrete electrical signals operating independently. .

[0269] FIG. 24 applies to the fuze setting operation of all of the fuze setting systems disclosed herein, i.e. , to all of the various systems that includes a fuze, an incompatible fuze setter, and a fuze setter adapter in accordance with the present disclosure, where the fuze setter adapter is utilized to resolve the incompatibility between the fuze and fuze setter.

[0270] It will be understood that a fuze setting system in accordance with the present disclosure may include a plurality of fuzes that have different interfaces for one of communications and electric power transfer. The plurality of fuzes may include LF 10, and any of the disclosed next generation fuzes, such as fuzes 100 and 700. Each of these plurality of fuzes 10, 100, 700 is capable of being interfaced with the same fuze setter (i.e., a common fuze setter) such as LFS 12, simply by providing a fuze setter adapter that makes the plurality of fuzes 10, 100, 700 compatible with the common fuze setter (i.e., LFS 12). The second region of the fuze setter adapter will be substantially identical since it is required to matingly engage with and communicate with the common fuze setter 12. The first region of the fuze setter adapter will be different in order to enable the fuze setter adapter to matingly engage with and communicate with the differently configured plurality of fuzes 10, 100, 700.

[0271] It will be understood that a fuze setting system in accordance with the present disclosure may include a plurality of fuze setters that have different interfaces for one of communications and electric power transfer. The plurality of fuze setters may include LFS 12, NGFS 102, and NGFS 102A, for example. Each of these plurality of fuze setters 12, 102, 102A is capable of being interfaced with the same fuze (i.e., a common fuze) such as NGF 700, simply by providing a fuze setter adapter that makes NGF 700 compatible with any particular fuze setter e.g. 12, 102. The first region of the fuze setter adapter will be substantially identical since it is required to matingly engage with and communicate with the common NGF 700. The second region of the fuze setter adapter will be different in order to enable the fuze setter adapter to matingly engage with and communicate with the differently configured plurality of fuze setters 12, 102, 102A.

[0272] The fuze setter adapter concept proposed herein is applicable to any munitions application where there may be a need to program a fuze with an otherwise incompatible fuze setter. The fuze setter adapter concept Is contemplated to be utilized across platforms, whereby a fuze setter designed for a particular munition fuze may be used to program fuzes for different munitions. Conversely, fuze setter adapters can allow a fuze to be programmed by fuze setters not originally intended to program that particular fuze. For example, a fuze for a mortar round could be programmed using a fuze setter designed for a different artillery projectile, e.g., a 155mm projectile. The fuze setter adapter provides flexibility to the field by extending the versatility of fuzes to be programmed by otherwise incompatible fuze setters and vice versa.

[0273] Various inventive concepts may be embodied as one or more methods, of which an example has been provided. The acts performed as part of the method may be ordered in any suitable way. Accordingly, embodiments may be constructed in which acts are performed in an order different than illustrated, which may include performing some acts simultaneously, even though shown as sequential acts in illustrative embodiments.

[0274] While various inventive embodiments have been described and illustrated herein, those of ordinary skill in the art will readily envision a variety of other means and/or structures for performing the function and/or obtaining the results and/or one or more of the advantages described herein, and each of such variations and/or modifications is deemed to be within the scope of the inventive embodiments described herein. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the inventive teachings is/are used. Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, many equivalents to the specific inventive embodiments described herein. It is, therefore, to be understood that the foregoing embodiments are presented by way of example only and that, within the scope of the appended claims and equivalents thereto, inventive embodiments may be practiced otherwise than as specifically described and claimed. Inventive embodiments of the present disclosure are directed to each individual feature, system, article, material, kit, and/or method described herein. In addition, any combination of two or more such features, systems, articles, materials, kits, and/or methods, if such features, systems, articles, materials, kits, and/or methods are not mutually inconsistent, is included within the inventive scope of the present disclosure.

[0275] The above-described embodiments can be implemented in any of numerous ways. For example, embodiments of technology disclosed herein may be implemented using hardware, software, or a combination thereof. When implemented in software, the software code or instructions can be executed on any suitable processor or collection of processors, whether provided in a single computer or distributed among multiple computers. Furthermore, the instructions or software code can be stored in at least one non-transitory computer readable storage medium.

[0276] Also, a computer, such as external host 1900, that is used to execute the software code or instructions via its processors may have one or more input and output devices. These devices can be used, among other things, to present a user interface. Examples of output devices that can be used to provide a user interface include printers or display screens for visual presentation of output and speakers or other sound generating devices for audible presentation of output. Examples of input devices that can be used for a user interface include keyboards, and pointing devices, such as mice, touch pads, and digitizing tablets. As another example, a computer may receive input information through speech recognition or in other audible format. Such computers may be interconnected by one or more networks in any suitable form, including a local area network or a wide area network, such as an enterprise network, and intelligent network (IN) or the Internet. Such networks may be based on any suitable technology and may operate according to any suitable protocol and may include wireless networks, wired networks or fiber optic networks.

[0277] The various methods or processes outlined herein may be coded as software/instructions that is executable on one or more processors that employ any one of a variety of operating systems or platforms. Additionally, such software may be written using any of a number of suitable programming languages and/or programming or scripting tools, and also may be compiled as executable machine language code or intermediate code that is executed on a framework or virtual machine.

[0278] In this respect, various inventive concepts may be embodied as a computer readable storage medium (or multiple computer readable storage media) (e.g., a computer memory, one or more floppy discs, compact discs, optical discs, magnetic tapes, flash memories, USB flash drives, SD cards, circuit configurations in Field Programmable Gate Arrays or other semiconductor devices, or other non- transitory medium or tangible computer storage medium) encoded with one or more programs that, when executed on one or more computers or other processors, perform methods that implement the various embodiments of the disclosure discussed above. The computer readable medium or media can be transportable, such that the program or programs stored thereon can be loaded onto one or more different computers or other processors to implement various aspects of the present disclosure as discussed above.

[0279] The terms“program” or“software” or“instructions” are used herein in a generic sense to refer to any type of computer code or set of computer-executable instructions that can be employed to program a computer or other processor to implement various aspects of embodiments as discussed above. Additionally, it should be appreciated that according to one aspect, one or more computer programs that when executed perform methods of the present disclosure need not reside on a single computer or processor, but may be distributed in a modular fashion amongst a number of different computers or processors to implement various aspects of the present disclosure.

[0280] Computer-executable instructions may be in many forms, such as program modules, executed by one or more computers or other devices. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. Typically the functionality of the program modules may be combined or distributed as desired in various embodiments.

[0281] Also, data structures may be stored in computer-readable media in any suitable form. For simplicity of illustration, data structures may be shown to have fields that are related through location in the data structure. Such relationships may likewise be achieved by assigning storage for the fields with locations in a computer-readable medium that convey relationship between the fields. However, any suitable mechanism may be used to establish a relationship between information in fields of a data structure, including through the use of pointers, tags or other mechanisms that establish relationship between data elements.

[0282] All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of the defined terms.

[0283] The term "logic”, if used herein, includes but is not limited to hardware, firmware, software, and/or combinations of each to perform a function(s) or an action(s), and/or to cause a function or action from another logic, method, and/or system. For example, based on a desired application or needs, logic may include a software controlled microprocessor, discrete logic like a processor (e.g., microprocessor), an application specific integrated circuit (ASIC), a programmed logic device, a memory device containing instructions, an electric device having a memory, or the like. Logic may include one or more gates, combinations of gates, or other circuit components. Logic may also be fully embodied as software. Where multiple logics are described, it may be possible to incorporate the multiple logics into one physical logic. Similarly, where a single logic is described, it may be possible to distribute that single logic between multiple physical logics.

[0284] Furthermore, the logic(s) presented herein for accomplishing various methods of this system may be directed towards improvements in existing computercentric or internet-centric technology that may not have previous analog versions. The logic(s) may provide specific functionality directly related to structure that addresses and resolves some problems identified herein. The logic(s) may also provide significantly more advantages to solve these problems by providing an exemplary inventive concept as specific logic structure and concordant functionality of the method and system. Furthermore, the logic(s) may also provide specific computer implemented rules that improve on existing technological processes. The logic(s) provided herein extends beyond merely gathering data, analyzing the information, and displaying the results. Further, portions or all of the present disclosure may rely on underlying equations that are derived from the specific arrangement of the equipment or components as recited herein. Thus, portions of the present disclosure as it relates to the specific arrangement of the components are not directed to abstract ideas. Furthermore, the present disclosure and the appended claims present teachings that involve more than performance of well-understood, routine, and conventional activities previously known to the industry. In some of the method or process of the present disclosure, which may incorporate some aspects of natural phenomenon, the process or method steps are additional features that are new and useful.

[0285] The articles“a” and“an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean“at least one.” The phrase“and/or,” as used herein in the specification and in the claims (if at all), should be understood to mean“either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with“and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the“and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to“A and/or B”, when used in conjunction with open-ended language such as“comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc. As used herein in the specification and in the claims,“or” should be understood to have the same meaning as“and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as“only one of or“exactly one of,” or, when used in the claims,“consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term“or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e.“one or the other but not both”) when preceded by terms of exclusivity, such as“either,”“one of,”“only one of,” or "exactly one of.”“Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law. [0286] As used herein in the specification and in the claims, the phrase“at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase“at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example,“at least one of A and B” (or, equivalently,“at least one of A or B,” or, equivalently“at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.

[0287] When a feature or element is herein referred to as being“on” another feature or element, it can be directly on the other feature or element or intervening features and/or elements may also be present. In contrast, when a feature or element is referred to as being“directly on” another feature or element, there are no intervening features or elements present. It will also be understood that, when a feature or element is referred to as being“connected”, “attached” or“coupled” to another feature or element, it can be directly connected, attached or coupled to the other feature or element or intervening features or elements may be present. In contrast, when a feature or element is referred to as being“directly connected”, "directly attached” or “directly coupled” to another feature or element, there are no intervening features or elements present. Although described or shown with respect to one embodiment, the features and elements so described or shown can apply to other embodiments. It will also be appreciated by those of skill in the art that references to a structure or feature that is disposed“adjacent” another feature may have portions that overlap or underlie the adjacent feature.

[0288] Spatially relative terms, such as“under”,“below”,“lower”,“over”,“upper”, “above”,“behind”,“in front of", and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures it will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is inverted, elements described as“under” or“beneath” other elements or features would then be oriented“over” the other elements or features. Thus, the exemplary term“under” can encompass both an orientation of over and under. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. Similarly, the terms “upwardly”,“downwardly”,“vertical”,“horizontal”,“lateral”,“transverse”,“longitudinal”, and the like are used herein for the purpose of explanation only unless specifically indicated otherwise.

[0289] Although the terms“first” and“second” may be used herein to describe various features/elements, these features/elements should not be limited by these terms, unless the context indicates otherwise. These terms may be used to distinguish one feature/element from another feature/element. Thus, a first feature/element discussed herein could be termed a second feature/element, and similarly, a second feature/element discussed herein could be termed a first feature/element without departing from the teachings of the present invention.

[0290] An embodiment is an implementation or example of the present disclosure. Reference in the specification to“an embodiment,”“one embodiment,” “some embodiments,”“one particular embodiment,”“an exemplary embodiment,” or “other embodiments,” or the like, means that a particular feature, structure, or characteristic described in connection with the embodiments is included in at least some embodiments, but not necessarily all embodiments, of the invention. The various appearances “an embodiment,” “one embodiment,” “some embodiments,” “one particular embodiment,”“an exemplary embodiment,” or“other embodiments,” or the like, are not necessarily all referring to the same embodiments.

[0291] If this specification states a component, feature, structure, or characteristic “may”, “might”, or “could” be included, that particular component, feature, structure, or characteristic is not required to be included. If the specification or claim refers to“a” or“an” element, that does not mean there is only one of the element. If the specification or claims refer to“an additional” element, that does not preclude there being more than one of the additional element.

[0292] Additionally, the method of performing the present disclosure may occur in a sequence different than those described herein. Accordingly, no sequence of the method should be read as a limitation unless explicitly stated. It is recognizable that performing some of the steps of the method in a different order could achieve a similar result.

[0293] In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including," “carrying,” “having,” “containing,” “involving,”“holding,”“composed of,” and the like are to be understood to be open- ended, i.e., to mean including but not limited to. Only the transitional phrases “consisting of” and “consisting essentially of” shall be closed or semi-closed transitional phrases, respectively.

[0294] In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed.

[0295] Moreover, the description and illustration of various embodiments of the disclosure are examples and the disclosure is not limited to the exact details shown or described.
