Description

Clamping device for headsets {CLAMPING DEVICE FOR A HEADSET}

The present invention relates to a headset used for placing a speaker in a user's ear. In particular, the present invention relates to a clamping device for receiving and securing an intra-concha type headset in a lower concha of a user's ear.

Since the end of the 20th century, the cellular telephone industry has grown tremendously around the world. In early analog systems defined by the standard Advanced Mobile Phone System (AMPS) and Nordic Mobile Telephone (NMT), growth has been in recent years (as described in, for example, EIA / TIA-IS-54-B and IS-136). Digital solutions for cellular wireless network systems, such as D-AMPS and Global System for Mobile Communications (GSM), are almost exclusively focused as standards. For example, different digital transmission schemes are used in many different systems, such as time division multiple access (TDMA) or code division multiple access (CDMA). Currently, cellular technology is entering the so-called third generation, adding some advantages over the former second generation, the digital system mentioned above. Among these advantages, increased bandwidth is provided, which enables efficient communication of more complex data. The third generation of mobile systems is called UMTS (Universal Mobile Telephony system) in Europe, CDMA2000 in the US, and to some extent already in Japan. Furthermore, the first generation of personal communication networks (PCNs) using low-cost, pocket-sized, cordless phones that can be conveniently carried and used to make or receive calls from home, office, street, car, etc. It is widely believed that) will be provided by, for example, a cellular carrier using the next generation of digital cellular system infrastructure.

Increasing use of portable communication terminals has accompanied the demand for easy and convenient operation of such devices. In particular, manufacturers of mobile cellular radio telephones have long struggled to provide efficient hands-free operation. It is desirable to provide hands-free telephones for automobiles, for example, for the safety and convenience of the driver. In hands-free operation, the driver of the vehicle can use both hands to control the vehicle.

One method of hands-free operation can be achieved by simply increasing the gain of the microphone and speaker of the telephone to allow the user to speak and listen at a distance from the device. Such telephones are commonly called speakerphones. However, some problems relate to systems configured in this way. For example, feedback and interference due to ambient noise often make the user's words difficult to understand clearly. To offset the problems caused by ambient noise, the microphone gain can be reduced by placing an external microphone directly near the user's mouth, wired to the main body of the wireless telephone. Nevertheless, since telephone speakers must be operated at high volume, the privacy of the received telephone is violated.

Another solution is a headset with speakers, and possibly a microphone, the cable connecting the headset to the main telephone device. Although having improved performance and privacy, the headset must be wired to the wireless telephone device. Line connections are often inconvenient, in particular inconvenient to use a portable cordless phone. For this reason, a wireless headset for wirelessly communicating with a communication terminal has been developed. In today's wireless headset systems, communication can be accomplished, for example, by infrared or wireless transmission. Headsets including Bluetooth technology for short-range wireless communication with communication terminals, such as mobile telephones, have also been described.

Various headset devices have been used to position and secure the speaker of the headset adjacent to the user's ear. A speaker or voice converter is placed adjacent to the user's ear to deliver voice communication to the user. A common headset design, which houses voice speakers adjacent to the user's ear, includes a headband style headset that fits over the user's head and places the voice converter in front of the user's ear canal. Typically, this style headset includes a stiff metal band or other rigid type support, which is weighted on the side opposite the side that houses the voice speaker to secure the headset over the user's head. Balanced. If two voice speakers are included, one on each side of the headband style headset, no weighting or balance is required. Such headsets are usually heavy and mechanically complex for some users, making it difficult to wear headband style headsets for extended periods of time.

Conventional outer ear style headsets place a voice transducer in the lower outer ear of the ear, between the tragus and the anti-tragus. However, different ear shapes and sizes make it a single design that makes it difficult to fit the user's ear and secure the headset. Usually, as described above, the receiver will be held in place by a headband, or other mechanical device or stabilizer. An ear hook that has been used to secure the voice transducer in or on the user's ear is an example of such a mechanical stabilizer. The ear hook is a large semicircular component that fits around the top of the user's ear, between the ear's helix and the side of the user's head. The wireless transducer is then attached to the body of the ear hook and housed in the lower outer ear in front of the ear canal. Certain configurations of ear hooks and headbands suffer from a conflict with the user's eyeglass frame.

For purposes of explanation and to aid in the understanding of the prior art and the arrangement of the respective devices for the present invention, a schematic drawing of an ordinary person's ear is shown in FIG. The outer ear, or pinna, is an irregularly concave cartilaginous member consisting of a number of elevations and depressions that give each ear its own unique shape and shape. The two wheels 2 are the bent outer rims of the ears. Less than two wheels 2 are antihelix 3. The great wheels 3 are bent protrusions that exhibit curvature around the outer ear, which is a deep cavity containing an inlet up to the ear canal 4. The outer ear is divided into two parts, the upper outer ear 5 and the lower outer ear 6, by a two-wheeled crux 7 that bends the outer periphery of the ear and extends inward with respect to the vertical center point of the ear. The upper outer ear 5 lies above the crux 7 of the two wheels and below the big wheels 3. The lower outer ear 6 lies below the crux 7 of the two wheels and surrounds the inlet up to the ear canal 4. The outer ear wall 8 separates the outer ear from the major wheel 3. In front of the lower outer ear 6, protruding from the front of the ear to the rear is tragus 9, which is an approximately small semi-circular protrusion. Facing the migration (9) and separated by the deep bend of the intertragic notch (10) is the large migration (11). An intertrastral notch 10 is formed between the migration 9 and the migration 11.

There is a need for a convenient mechanical support device for supporting a voice transducer placed in an intertrastral notch of a user's ear.

US Pat. No. 5,953,435 to Mullin et al. Proposes a type of stabilizing device that plugs into the outer ear with a length-adjustable outer wall hanger that carefully houses the voice transducer or speaker in the user's ear. The voice speaker is completely contained within the outer cell of the stabilizer and contained within the support. In the outer cell, the wall-hanging carrier of the outer ear slides along a groove formed entirely in the exterior of the outer cell. The outer wall hook projects vertically away from the inner wall of the outer cell and the outer wall hook carrier to engage the outer wall of the user's ear. When worn, the voice speaker is placed in the user's ear between migration and migration. The ear wall mount is then placed to slide against the ear wall of the user's ear to protect the speaker in the ear.

The design proposed by the prior patents has certain drawbacks. For that, the sliding device requires that the two interacting structures fit comfortably into each other, so that the grips of the ear do not loosen and loose. After extensive use, so-called stabilizers will wear to the extent that they inevitably have side effects on the possibility of holding the grip. Furthermore, because the device is designed to be used in close contact with a person's skin, the interacting structures will become dirty, increasing the tendency of the grip to loosen between the interacting structures. Another drawback is that the above-mentioned prior art solutions require manual adjustment for proper clamping of the outer ear.

It is therefore an object of the present invention to provide a means for securely attaching a headset proximate to an ear channel of a user. An aspect of this object is to provide a solution that overcomes the above-identified deficiencies associated with the prior art.

According to the present invention, the object is to provide a first clamping structure having a first ear engagement rim, a second clamping structure having a second ear engagement rim, and a free engagement of the type which plugs into a human ear and outer ear. By means of a clamping device for an external ear plug type voice headset comprising a support structure equipped with means for adjusting the spacing between the first and second ear engagement rims. The means for resiliently exert a force on the rims of the engagement that are apart from each other.

Preferably said means for adjusting the spacing comprises a spring structure. The spring structure is designed to exert a linear force on the second clamping structure, to separate it from the first clamping structure. The spring structure is in one embodiment designed to pull the second clamping structure away from the first clamping structure. In another embodiment, the spring structure is designed to push the second clamping structure away from the first clamping structure.

Preferably, the first clamping structure is configured to be fixed relative to the support structure, while the second clamping structure is attached to the support structure such that the rim of the second ear engagement can be moved away from the first clamping structure.

In a first embodiment, the second clamping structure is slidably attached to the support structure.

In a second embodiment, the second clamping structure is pivotally attached to the support structure.

In the second embodiment, the spring structure is designed to pivot the second clamping structure such that the rim of the second ear engagement is away from the rim of the first ear engagement.

Advantageously, said first clamping structure protrudes from said support structure in a first direction, while said second clamping structure is about a first axis of rotation extending perpendicular to a line intersecting said first and second clamping structures. You can turn.

In a first variant of the second embodiment, the second clamping structure has a central axis extending in the first direction, while the rotation axis is off center from the central axis.

Preferably, the axis of rotation off the center is parallel to the center axis.

Advantageously, the rim of the second ear engagement defines a curved outer boundary portion of the second clamping structure, preferably defining a circle arc with respect to the central axis.

In a third embodiment, the first axis of rotation extends perpendicular to the first direction.

In the third embodiment, the second clamping structure has an arm member extending from the rotation axis to the rim of the second ear engagement.

Preferably, the rim of the second ear engagement defines a protruding portion of the arm structure.

The first clamping structure may mount a speaker. Alternatively, the second clamping structure mounts a speaker.

The support structure may further mount a microphone.

The present disclosure relates to a headset for use with a communication terminal. The present invention includes a headset that is pre-connected to a communication terminal such as a mobile phone, a media player, and the like, and a wireless headset designed for wireless communication with a communication terminal or station. By headset is generally meant a device configured to be worn by a user as a communication interface, comprising means for communicating with a communication terminal by at least a wired or wireless transmission of speaker and voice data. The headset may include a microphone. Furthermore, the headset is generally configured with some form of attachment means for keeping the headset in the user's preferred position with the speaker placed close to the ear canal and the microphone, if included, placed near the user's mouth. do. Thus, the headset may include all the features for a communication terminal, such as a mobile phone, but may alternatively only configure a voice interface for the user. In this regard, the following description relates to the latter embodiment, but one skilled in the art will recognize that the present invention is equally applicable to the first embodiment.

2 shows a side view of a headset 20 equipped with a clamping device for freely attaching the headset to the outer ear of a human ear. Headset 20 includes a support structure 23 that may include one or more structures. The support structure mounts a circuit 25 for the headset, a clamping device for attaching the headset to the ear, and a speaker 29. The speaker is enclosed with a protective casing 22 to define a part of the clamping device. The headset may also include a microphone 28.

The clamping device comprises a first clamping structure 21 protruding from the support structure. At an outer boundary of the first clamping structure 21, a first engagement rim 26 is formed. The support structure further mounts a second clamping structure 22, which is remote from the first clamping structure 21. The embodiment described in FIG. 2 shows that two interacting clamping structures protrude substantially parallel to each other with intermediate spacing in between. The second clamping structure 22 has a rim 27 of a second ear engagement. The spacing between the two clamping structures 21, 22, or more precisely, can be adjusted between the rims of the first 26 and second 27 ear engagements facing away from each other. In this way, by reducing this gap or distance, the clamping device can be introduced into the outer ear of the human ear. Once in place, the gap is such that the rim 26 of the first ear engagement meshes with the conchal wall 8 and the rim 27 of the second ear engagement enters the intertragic notch 10. Increased to engage the ear.

25 very schematically shows the headset 20, introduced into the human ear 1. The outer ear wall 8 and the trachea 9 accept the rims of the first (26) and second (27) ear engagements, respectively, to accommodate the headset in place. The speaker is preferably included in the second clamping device such that the speaker lies adjacent to the ear canal 4. The headset further comprises means 24 for applying a force to the first and second ear engagement rims that are remote from each other.

3 shows a circuit of the headset 2, in which more elements can be implemented than described. A transceiver device 32 is included for transmitting and receiving voice data. In the case of a wireless transmit / receive headset 20, a transceiver device 32 is included or connected to the antenna 35. In an embodiment using infrared transmission (not shown), the transceiver is connected to a light emitter and a light detector, for example a light emitting diode (LED) and a photodiode. Optionally, the transceiver is connected to a cord for wired transmission. Voice data is transferred between the communication terminal and the headset 20 as a carrier signal modulated, for example, in radio or infrared. Therefore, a voice converter is additionally included in the transceiver device 32 of the headset 20 for converting between the voice data and the voice signal, like speech. The transceiver device 32 is connected to the speaker 29 and the microphone 28. The power supply 33 supplies electrical energy to the electronics of the headset 20. Since the connectors 9 and 10 are coupled to the power supply 33 so that the power supply can be charged, it can be accessed from the outside of the case enclosing the circuit 25 of the headset. The power supply 33 is a rechargeable battery but may also be a capacitor. Power connectors 37 and 38 are included for connection to the charger.

In one embodiment, the transceiver device 32 of the headset 20 includes a transmitter and a receiver, allowing dual communication with the communication terminal. Headset 20 also includes a transmit / receive element, such as antenna 35, for transmitting and receiving signals from a communication terminal. For RF (radio frequency) signals, the antenna may be a small coil or wire or a flat pattern of conductive material disposed within the body of the headset. In a preferred embodiment, the transceiver 32 and antenna 35 may be designed according to Bluetooth technology for short-range wireless communication. The receiver detects and demodulates the signal from the antenna to produce a speech signal. Several types of modulation may be used, including frequency modulation (FM), pulse width modulation (PWM), amplitude modulation (AM), single sideband (AM), quadrature phase shift modulation (QPSK), and the like. The voice signal produced by the receiver passes through the voice amplifier and speaker 29. The microphone 28 converts the speech represented by the user of the headset 20 into an electrical signal that is supplied to a band pass filter of the transceiver device 32 to reduce extraneous noise. The output of the filter can be amplified by a suitable amplifier, the output of which is provided to the transmitter of the transceiver device 32. Transceiver 32 modulates the RF carrier with the amplified output. It will be appreciated that the transceiver 32 may include a suitable voice signal to adjust the components. In either embodiment, the modulated carrier is coupled to an antenna 35 that radiates for reception of the communication terminal.

It will be pointed out that the present invention is equally applicable to headsets designed for reception only with speakers and no microphone.

4 shows a user 40 wearing a headset 20 with Bluetooth transmission capability. The headset 20 may be communicatively connected to the mobile telephone 42 by Bluetooth for further communication via the mobile telephone network. Furthermore, the same headset 20 can be communicatively connected to the PSTN or IP telephone 41 in the user's office or home by Bluetooth. Thus, the headset 20 can be connected to several other communication terminals, either mobile or stationary. One example is a desktop or laptop computer 43 on which voice-controlled software can be run. However, those skilled in the art will understand that a headset capable of communicatively connecting to different terminals does not need to use the same transmission interface for different terminals.

According to the invention, the clamping device of the headset comprises means for resiliently applying force to the interacting rims of the ear engaging away from each other. The following describes three different embodiments that realize this feature and some variations on each embodiment.

5 schematically shows a side view of a first embodiment of a headset clamping device. The first clamping structure 21 is fixed to the support structure 23, while the second clamping structure 22 can be moved along the support structure 23 toward the first clamping structure 21. The spring structure 53 is connected to the support structure 23 at one end 52 and to the second clamping structure 22 at the opposite end 51. 5 describes a clamping device in a rested state. The stopped state does not necessarily mean that the spring structure 53 does not have tension. In contrast, the spring structure 53 is slightly loaded or biased even in the stationary state of FIG. 5, with some form of stopping means (not shown) included to define the maximum spacing between the clamping structures 21, 22. .

FIG. 6 shows the same embodiment as FIG. 5 but shows a loaded state. Since the loaded state is taken by forcing the second clamping structure 22 towards the first clamping structure 21, the distance between each of the rims 26, 27 of the first and second ear engagements is reduced. . When the second clamping structure 22 is moved from the position shown in FIG. 5 represented by the broken line in FIG. 6 to the position shown by the fully drawn line in FIG. 6, the spring structure 53 is extracted. This means that a force must be applied to move the second clamping structure from the position of FIG. 5 to the position of FIG. 6. Furthermore, this means that when the two clamping structures 21, 22 are pressed together and placed in the outer ear of the human ear as in FIG. 6, after the second clamping structure 22 is released, the spring structure 53 is engaged with the ear. It will be used to maintain engagement between the rims 26 and 27 of the ear.

FIG. 7 shows an embodiment similar to that of FIGS. 5 and 6 with the difference that the spring structure 73 exerts a pushing force instead of a pulling force on the second clamping structure 22. Thus, when the second clamping structure is moved to the position of FIG. 8, the spring structure 73 is contracted rather than relaxed.

FIG. 9 shows an embodiment of the clamping device seen from the side designed to face the ear, ie from the upward facing side of FIGS. 5 to 8. 9 briefly describes one way of providing a means for displacing the second clamping structure 22 in relation to the first clamping structure 21. In the exemplary embodiment of FIG. 9, an elongated slot 92 is formed in the support structure 23, extending in the direction between the interacting clamping structures 21, 22. The second clamping structure 22, shown as a phantom, allows the second clamping structure 22 to slide closer or farther from the first clamping structure 22 in recesses or slots 92. It has a guide structure 91 fitted in the slot 92. Means for attaching to the spring structure and the second clamping structure 22 are not shown in FIG. 9, but may be any of those described in FIGS. 5 to 8, for example.

FIG. 10 shows a perspective view of a variant for the clamping device of FIG. 9. In the embodiment of FIG. 10, the second clamping device 22 is constructed on a slide 1001 which completely or partially encloses the opposing side edges of the support structure 23. In this way, the slide can be moved along the support structure 23. As it relates to FIG. 9, a particular implementation of the spring structure and its attachment is not described in FIG. 10.

Another variant of the first embodiment is shown in FIGS. 11 and 12. In FIG. 11, the second clamping structure 1002 is fixed to the support structure 23, while the first clamping structure 1101 is slidably connected to the support structure 23. The spring device 1105 is connected to the first clamping device 1101 at 1103, while the spring structure 1105 is connected to the support structure 23 at 1104. The embodiments described in Figures 11 and 12, respectively, in a stationary and loaded state, are designed to retract when the spring structure 1105 loads. Obviously, the device corresponding to FIGS. 5 and 6 may be applied to a variant of this embodiment, in which the first clamping structure 1101 is removed from the second clamping structure 1102 under the relaxation of the spring structure.

FIG. 13 shows a view of the embodiment of FIG. 11 seen from the side designed to face the ear, in a manner corresponding to that of FIG. 9; In this case, however, the second clamping structure 1102 is fixedly connected to the support structure 23, while the first clamping structure 1101 is connected to the guide 1301 moving in the elongated slot 1302 of the support structure. Or include the guide.

FIG. 14 shows a variation of a particular solution for obtaining sliding motion in the first clamping structure 1101, which corresponds to the diagram of FIG. 10. As such, the first clamping structure is connected to a slide 1401 which completely or partially surrounds the support structure 23 with respect to the opposing side edges. At that time, the slide 1401 is designed to slide near or away from the second clamping structure 1102 along the support structure 23.

The specification for the embodiments of FIGS. 11-14 simply shows that the clamping structure comprising the speaker is fixedly attached to the support structure, while the interactive clamping structure can be moved in relation to the support structure and the second clamping structure. . 5 to 10 show another device, which is a clamping structure comprising a speaker moved in relation to the first clamping structure and the support structure. However, the same effect is obtained by means of a spring structure designed to exert a force on the interacting clamping structures, respectively.

15 shows a side view of a second embodiment of a headset clamping device. Although this second embodiment has been described only for the variant with speakers configured in the clamping structure 22 that can be moved, one skilled in the art will understand that the same means may be applied to the first clamping structure to achieve placement. In the embodiment of FIG. 15, the first clamping structure 21 is fixed to the support structure 23. The second clamping structure 22 is configured slightly away from the first clamping structure 21 and generally projects in the same direction as the first clamping structure 21. The second ear engagement rim 27 of the second clamping structure 22 has a generally circular curvature with respect to the central axis 1501. This curvature may be semi-circular or may only define a portion of the circle, but the rim 27 of the ear engagement defines the circumference of the complete circle about the central axis 1501. The second ear engagement rim 27, defined by the front portion of the second clamping structure 22, supports the support structure 53 via a shaft 1505 extending substantially parallel to the direction of protrusion of the first clamping structure 21. ) The second clamping structure 22 may pivot about the shaft 1505, which defines a first axis of rotation 1502 that is off-centered from the central axis 1501. In this way, the rotation of the second clamping structure 22 about the first axis of rotation 1502 is directed away from the rim 26 of the first ear engagement and the rim 26 of the first ear engagement. This will cause a change in the distance between the rims 27. The spring structure 1503 is biased to force the rim 26 of the second ear engagement away from the rim 26 of the first ear engagement. The spring structure can be designed to exert a linear force at a position off center of the second clamping structure 22. However, as described in FIG. 15, the spring structure 1503 is helically configured with respect to the shaft 1503 and is connected to the support structure 23 at one end and to the second clamping structure 22 at the opposite end.

In FIG. 16, the second clamping structure 22 reduces the distance between the position of the rim 27 of the first ear engagement and the rim 27 of the second ear engagement facing away from the rim 26 of the first ear engagement. Pivoted approximately 90 ° with respect to the first axis of rotation 1502.

Finally, FIG. 17 shows the second clamping structure 22 being fully loaded with pivoting approximately 180 ° from the stationary state of FIG. 15. In this fully loaded state, a minimum obtainable gap is taken between the rims 26, 27 of each ear engagement. Since the clamping structures are placed in the outer ear of the ear by applying a force to the second clamping structure in this position, after releasing the second clamping structure, the second clamping structure is rotated by the force of the spring structure 1503 to engage the ear. will be.

18-20 show the state previously shown in FIGS. 15-17, seen from the side of the headset opposite the ear. These figures more clearly show how the second clamping structure 22 rotates about the first axis of rotation 1502 such that the outer boundary of the rim 27 of the ear engagement is shifted towards the rim 26 of the first ear engagement. Illustrated.

Figure 21 shows a third embodiment of the clamping device of the invention. In this case, the figure shows an embodiment in which the first clamping structure 21 with a speaker is fixed to the support structure 23, while the second clamping structure 22 can pivot in relation to the first clamping structure. Illustrated. However, as described above in connection with other embodiments, the same concept can be applied by instead turning the clamping structure with the speaker in relation to the interactive clamping structure fixed to the support structure 23. In the embodiment of FIG. 21, the second clamping structure 22 is connected to the support structure 23 by a shaft or hinge device defining a second axis of rotation 2105. In this case, the second axis of rotation 2105 extends perpendicular to the direction between the respective first and second terminal structures 21, 22, and perpendicular to the direction in which the first clamping structure 21 protrudes. Extend. The second clamping structure 22 is the point of articulation about the second axis of rotation 2105 away from the outer boundary defining the rim 27 of the second ear engagement on the second axis of rotation 2105. Cancer structure 2104 extending from Preferably, the rim 27 of the second ear engagement is defined by a portion protruding from the arm structure 2104 such that a hook like shape is defined. In the particular embodiment of FIG. 21, the portion 2102 of the second clamping structure 22, away from the second axis of rotation 2105, is connected to a spring structure 2101 which is connected to the support structure 23 at 2103. do. In this way, the force exerted by the spring structure 2101 generates a moment about the second axis of rotation 2105 such that the rim 27 of the second ear engagement falls away from the first clamping structure 21. FIG. 21 shows an embodiment in a stationary state, which, as before, is not shown but in a stationary state, with some form of stop means for preventing further rotation of the second clamping structure 22 from falling from the first clamping structure 21. Is maintained by.

FIG. 22 shows an embodiment of FIG. 21 in a loaded state. This loaded state is taken by rotating the second clamping structure 22 such that the rim 27 of the second ear engagement is moved toward the rim 26 of the first ear engagement of the first clamping structure 21. Because of this rotation, the spring structure 2101 relaxes, exerting a force on the second clamping structure to disengage the rim 27 of the second ear engagement from the rim 26 of the first ear engagement.

23 and 24 show a variant of the third embodiment for each of FIGS. 21 and 22. In this variant, the spring structure 2301 is instead wound about the second axis of rotation 2105, connected at one end to the support structure 23 and at the opposite end to the arm structure 2302 of the second clamping structure 22. Connected. FIG. 23 describes the stopped state while FIG. 24 describes the loaded state.

An advantage of the present invention is that only one action is required when attaching the headset to the ear, such as by pressing the rims of the ear engagement towards each other by the rotation or placement of one of the clamping structures. Once in place within the outer ear, the clamping structure, which can be rotated or moved, is released, which automatically takes the clamping engagement with the ear. The spring automatically adjusts the dimensions of the clamping system relative to the ear. This provides the user with a headset more conveniently constructed in accordance with the present invention than in the prior art, as it provides faster and more accurate attachment to the ear. Furthermore, since the clamping device is preloaded or biased by the spring device, the clamping effect will not be exacerbated by wear or sweating by the user.

In the foregoing, the principles, preferred embodiments and modes of operation of the present invention have been described. However, the invention should not be construed as limited to the specific embodiments set forth above. Apparently, although some features are highlighted with respect to specific embodiments, those skilled in the art will understand that some of these features may be applied to other described embodiments. Accordingly, it will be appreciated that the above-mentioned embodiments will be considered as examples rather than limitations, and that modifications may be made by those skilled in the art without departing from the scope of the present invention, as defined by the following claims.
