TECHNICAL FIELD OF THE INVENTION The present invention relates to electronic systems and methods for providing power to one or more electronic devices through a power delivery surface. [Prior Art] A variety of mobile electronic devices, such as toys, game devices, mobile phones, laptops's cameras' and personal digital assistants have been developed along with their power supply methods. Such devices typically include a battery that can be recharged by connecting it to a power source, such as an electrical jack, through a power line unit. In a typical architecture, the power line unit includes a jack connector and a battery connector. The jack connector is for connection to an electrical jack and the battery connector is for connection to a corresponding battery power outlet. The jack connector and battery connector are in communication with one another' so that electrical signals can flow 201008056 in between. In some architectures, the power line unit also includes a power adapter (adaptor) that is connected to the jack connector and the battery connector through the eight input lines and the wheel outlets, respectively, such that the power line The unit operates to become a power adapter. However, manufacturers typically make electronic devices of their own models and do not make their power line units compatible with other manufacturers' electronic devices or with other types of electronic devices. Thus, a battery connector made by one manufacturer will typically not fit into a battery power outlet © made by another manufacturer. Further, battery connectors made for one type of device will typically not fit into battery power sockets made for other types of devices. Manufacturers do this, often because of reasons such as cost, responsibility, different power needs, and several reasons for gaining greater market share. This can be a problem for the consumer because they must purchase a compatible power line single S for their particular electronic device. Because people tend to be easy

It is inconvenient and expensive to replace the device's for them to also have to replace the power line unit. In a step-by-step manner, power line units that are no longer useful are often discarded and wasteful; moreover, people usually have many different types of electronic devices, and it is inconvenient to have power line units for each electronic device, because & There is an electronic system that provides power to one or more different electronic devices. SUMMARY OF THE INVENTION The present invention uses an electronic system having a power transmission support structure for the power transmission surface of the mine, which is separated from the conductive area by a separate conductive area. 201008056

The present invention also uses a contact electronic device 'these contacts are configured such that when the electrical system is placed by the power transmission support structure, at least:::, the conductive regions One of the conductive regions and the other of the contacts are connected to the other conductive regions of the conductive regions. The power transfer surface and the contact arrangements are such that a potential difference can be provided to the contacts regardless of the orientation of the electronic device relative to the power transfer surface. The electronic device includes and carries a circuit 'the circuit receives a potential difference from a contact' to rectify the potential difference and provides a desired potential difference for powering the electronic device. The 'and advantages' will become preferred in the context of the present invention and other features, aspects, drawings, descriptions, and claims. [Embodiment] FIG. 1 is a perspective view of a power delivery system 100 for providing power to an electrical or electronic device 112 with a power delivery surface uia in accordance with the present invention. The power delivery system 100 can supply power to more than one electronic device made by the same or different manufacturers, and can be powered to different types of electronic devices, which would reduce the need for the consumer to have a power line unit for their use. The requirements for each electronic device. The electronic device 112 can be many different types such as toys, gaming devices, mobile phones, laptops, cameras, personal digital assistants, etc., most of the devices are mobile, and can be rechargeable batteries Powered by. However, the present invention is also applicable to an electronic device such as a desktop computer which is generally not regarded as a mobile type. The system 100 includes a power delivery support structure lu that is coupled to a power source (not shown) via a power line unit 113; the power source can be of many different types, such as an electrical outlet or battery, and is permeable to a single 7L 113 provides a conductive region with a potential difference to the separation of the crucible. The potential difference is provided to the electronic device 112 in response to the device 112 carried by the structure 1U on the surface 111& in this manner, the surface ma is operable to deliver power to the electronic device 112. The electronic device 112 can be powered by the power delivery surface in a number of different ways, for example, the surface 111a can provide charge to the ® battery included in the device 112. This is often the case for mobile devices. The device 112 can also be powered directly from the surface 111a, which is used in situations where the device 112 is not a battery operation, or where it is desired to operate the device 112 with its battery removed; this example is used when In the case of a laptop, the laptop is operable if power is supplied to the laptop by surface 11 13 after its battery has been removed. The power delivery support structure 111 can comprise a plurality of different materials, but preferably comprises an insulating material having separate conductive regions defining at least a portion of the surface 111a as explained in more detail below The conductive regions are separated to provide a potential difference to the electronic device 112. In this embodiment, electronic device 112 includes and carries contacts and electronic circuitry that communicate with one another. In operation, when the contacts engage the surface 11u, the circuit receives a potential difference from the power transfer surface through the contacts; the potential difference is rectified by the electronic circuit to provide a desired voltage that can be used to power the electronic device Potential. Advantageously, the circuit is carried by the device such that the circuit can be designed to receive from the power delivery surface 8 201008056

电位 Potential difference, and the device ιΐ2〇 is provided at the desired voltage potential. This feature is useful because it is sometimes desirable to: supply multiple electronic devices that operate at a voltage potential of ==. In some situations, the electronic devices are the same type of device (ie, 'two mobile phones'), the electronic devices may be of the same type and have the same voltage requirements, or the electronic devices may be of different styles And with different voltage requirements, the different patterns can be made by the same or different manufacturers. In other situations, the electronic devices are different types of devices (i.e., mobile phones and laptops), and different types of devices typically require different ranges of voltage potentials, although in some instances, such voltage potentials Again, the different types of devices can be made by the same or different manufacturers. Thus, the electronic circuitry for each device is designed such that the power delivery surface can provide power to multiple electronic devices having many different voltage requirements. According to the invention, the arrangement of the contacts enables the potential difference to be provided to the electronic circuit, irrespective of the orientation of the device 112 on the power transfer surface 111 & the 'potential' difference is provided to the electronic circuit for all angles 0 . This feature is advantageous for several reasons, such as the joints engaging the surface 111a such that at least two of the contacts are at different potentials without the need to align the contacts with the surface. In this embodiment, angle 0 corresponds to the angle between the side of structure 111 and reference line 142 which extends through device 112 and is parallel to surface ii2a. However, it should be noted that 'another reference can be used; here, the angle 0 has an approximate 〇. (: value with 360°. 201008056 This feature is also advantageous when powering multiple electronic devices, as these electronic devices can be placed on the surface Ilia in many different ways; this allows for more efficiency The surface 111a is used to cause more devices to be carried over and over the power transport surface. This is for use in which there are not enough electrical outlets available to individually charge the multiple electrons. In the case of the device, roughly, when the length L and/or the width W is increased, the structure 111 can carry more electronic devices; when the length L and/or the width W is reduced, less electronic devices are carried. Structure U1 The number of devices that can be carried can also vary depending on the size of the device, for example, the mobile phone system is typically smaller than a laptop. The power delivery support structure 111 can have many different shapes, but here it is surfaced 111a is rectangular so as to cause the structure 111 to define a cube. The surface 111a is shown as being substantially flat, and the separate conductive regions are defined by the regions of insulating material. From the continuous surface, the surface 1Ua extends between the opposite sides 115a and 11b, and likewise extends between the opposite sides 115c and 115d. The opposite sides 115c and 115d extend from the side 115& And the opposite ends of U5b, and between the ends. The sides 115a and 115b are oriented at a non-zero angle with respect to the sides 115c and 115d; in this particular example, the non-zero angle is about 9〇. Because the surface Π la-shaped rectangle "in other embodiments, the surface 丨丨la may be a curved triangle' and its like shape; when the surface 1 i la is circular, the structure i 丄丄 may be defined as a The electronic system 100 has a number of different embodiments that provide the above-described features and advantages, as well as other features and advantages, and a number of embodiments are described in U.S. Patent Application Serial No. 10,080, the entire disclosure of which is incorporated herein by reference. A number of more embodiments will be described herein. FIG. 2 is a top view of an electronic system 'implemented as an electrical system for providing power to an electronic device 112 with a power delivery surface. system 101. The system 1 〇 1 is similar to system i 00 and includes a power delivery support structure 111 and a power line unit 113. In this embodiment, the power transfer surface indicated as surface 111 a' includes two separate conductive regions (represented Regions 116 and 117); regions 116 and 117 are separated from one another by insulating regions 119 (Fig. & and Figure 5b) and define separate continuous surfaces. Region 119 provides electrical isolation between conductive regions 116 and 117. So that a potential difference can be provided between the conductive regions. If a current flows between the conductive regions 116 and 117, when the junction is bonded to the surface 1 i丨a ', current flows through the electronic device 112. electronic circuit. In this manner, when the device 112 is carried by the power delivery support structure U1, power can be supplied to the device 112; if current flows between the regions 丨16 and 丨17 without flowing through the electronic circuit, typically, This current is an unpleasant leakage current. In general ®, when the separation between the regions 116 and 117 is increased, the leakage current is reduced, and similarly, when the separation between the regions 1丨6 and 117 is reduced, the leakage current is increased. The leakage current is also dependent on the material contained in the insulating region 119. In this embodiment, the conductive region i 16 includes a substrate contact 丨 14 extending along the side 115a and between the sides U5c and U5d; the region 116 also includes a first plurality of pads, the pads Some of the pads are shown as 114a, 114b, and U4e; the pads are connected to the base contact 114, extending from the base contact 114 outwardly and toward the side edge 115b at 11 201008056. The conductive region 117 includes a substrate contact 11 8 extending along the side 1丨5b and between the side edges 55c and 115d; the region 117 also includes a second plurality of pads, and some of the interfaces The pads are shown as 118a, 1 i8b, and 118c; the pads are connected to the substrate contacts 118' and extend outwardly from the substrate contacts 8 and toward the sides 115a. It should be noted that the contacts 丨丨4 and 丨丨8 extend all the way between the sides 115c and 11d; however, in other embodiments, the contacts 114 and 117 may extend partially to the side 丨Between 5c and 丨丨5d; and, © It should be noted that although the substrate contacts 114 and 118 in this example are shown as being rectangular, in other examples they may have other features such as curved or triangular. shape. In this example, pads 114a-114c and 118a-118c extend parallel to each other and are spaced apart such that pads 114a are positioned between pads 118a and 118b, and pads U4b are positioned between pads U8b and 118c. between. As shown in Figure 2, the other pads in regions 116 and 117 are intersected and spaced in the same manner. It should be noted that in some instances, different pads in regions 117 and 118 may be connected together by vias. Power line unit 113 includes wires 113a and 113b that are connected to conductive regions 116 and 117, respectively. In an operational mode, the power supply provides conductive regions U6 and 117 at different voltage potentials through corresponding conductors 113a and 113b; in this mode, when device 112 is carried on surface 111a, and contacts At the bonding surface 111a, a potential difference will exist between the regions 116 and 117' and the device 112 is supplied with power to respond to the potential difference. In this aspect, the 'surface Ilia' configuration is such that a potential difference is provided between at least two junctions of the contacts carried by the device m. It should be noted that 'more than two potentials can be provided by the power line unit 113 to the surface 111a'' and that the use of the two potentials herein is for illustrative purposes. For example, power line unit 113 can include three wires providing a positive potential 'negative potential, and zero potential to a corresponding number of conductive regions that are the same as or similar to regions 116 and 117. 3 is a side view of power delivery system 101 with electronic device 112 positioned over power delivery support structure ® 111. In accordance with the present invention, electronic device 112 includes and carries a plurality of contacts 120 that extend through surface H2a of electronic device 112. In this example, contact 120 includes four contacts, designated as contacts 12〇a, 12〇b, 12〇c, and l2〇d (Fig. 1a). In accordance with the present invention, electronic device 112 also includes and carries circuitry 13A that is in communication with contact 12A. The contact 12 is configured such that when the contact 120 engages the surface 111a, there is a potential difference between at least two contacts of the contacts 12A, and the contacts 120 are configured such that a potential difference is provided to the electronic circuit, Regardless of the orientation of device 112 above surface 111a, this potential difference is provided to circuit 13 and is rectified to provide rectified voltage #vvpower between conductive contacts 133a and n3b. In this manner, when the backup contact 120 engages the power transfer surface, the power transfer surface can provide a potential difference to the circuit 13 through the electrical contact 120. The conductive contacts 133a and 133b (Figs. 4, 9b, 13b, 15c, etc.) are respectively connected to the contacts 139a and n9b (Fig. 15b, 15db, 15e, 15f, etc.) of the power system 131, and the power system m usually includes a reusable The charged battery 13 201008056 battery is charged in response to the voltage signal Vpower; when the contact 120 is detached from the surface 11 la 'the system 131 will supply the power device 112. In the following description, the conductive contacts 133a and 133b are sometimes collectively referred to as contacts 133, and the contacts 139a and 139b are sometimes collectively referred to as contacts 139. In this embodiment, the 'insulating zone 119 extends through the gap 111 of the surface 111 a such that the regions 116 and 117 are spaced apart from each other; however, in other examples the 'region 119 may include, for example, rubber, plastic, stone eve A base resin, or an insulating material of another dielectric material, may extend upwardly such that it separates regions 116 and 117. An example is shown by the replacement arrow 198, wherein the region 119 includes an insulating material extending upwardly between the regions 116 and 117 such that it is flush with the regions 116 and 117; in other examples, the region 119 It may also be above or below the level of the regions 116 and 117 'this is indicated by the replacement arrow 199, wherein the region 119 there extends upwardly between the regions ι 6 and U7 such that it extends over the region 116 and Above the level of 117. In some instances, the upper surface of region 119 can be tapered such that junction 120 can easily slide across surface 111a; the ease with which joint 12 slid across surface 11 la' will follow the joint The different shapes for the contacts 120 will be described with reference to Figures 12a and 12b, depending on the shape of the 12 turns. It should be noted that the power transfer surface 1Ua is defined by the regions 116, 117, and 119, and the regions 116, 117, and ι 9 are typically thinner than the thickness t (Fig. 在. In this manner, the surface 1Ua, exhibiting a substantially flat shape. In a particular example, the thickness t is about two tenths or more of 丨 mm to 5 mm' and the regions 116, 117, and 119 each have a degree of 201008056 than about i mm. Two smaller thicknesses; however, the thickness t and the PCT τ ήΕ -τ θ_ι« of the regions 116, 117, and 119 may have values outside the ranges. In Fig. 3, in the region 116 The Q field 119 between and 7 is an air gap such that it has a material thickness of zero millimeters. Figure 4 is a schematic illustration of an embodiment of a circuit 13A in accordance with the present invention. In this example, 'circuit 13G includes a connection to The junction 12〇a of the diode ΐ32^n-type side and the diode 132biP-type side is connected to the contact point (10) of the 〇-type side and the diode-type side of the diode 13仏, and is connected to the diode 132e. The junction of the p-side of the n-type side and the diode 132 is 2, and is connected to the n-type of the diode And a contact 120d on the p-type side of the diode (10). The diodes i32a, 132c, 132e, and U2g each have a corresponding p-type side connected to the conductive contact 133b, and the diodes 132b, 13 2f And 132h each have a corresponding n-side connected to the conductive contact U3a. In this embodiment, the circuit 130 operates to become a bridge rectifier that passes through the contact 120 to receive a potential difference from the surface 111a, and responds , 彳 彳 5 said Vp () wer between the conductive contacts 133a and 133b. As described above, the contacts 120 are configured such that when the surface lll' is engaged Between the circuits 130 provides a potential difference between any of the contacts 12A to the conductive contacts 133a and 133b, and then provides a potential difference between the contacts 133a and 133b through the contacts 139a and 139b to the power System 13 1 is used as signal Vpower. In this manner, signal Vpower is used to become a source of power for power system 131. Circuit 130 can vary the potential difference received from surface 111a' to achieve this 15 ❹ ❺ 201008056 : by reducing it to The desired potential difference is compatible with the device. As mentioned above, the desired potential difference is usually within the potential difference of the desired range compatible with the device η: the potential difference of the range can be based on the old power The system and the many different factors of the components included in the circuit I3G_ can also be determined according to the size of the contact m and the material contained in the contact 120. For example, if the electronic device 112 is a mobile phone, It operates normally in a potential difference such as a special range of about 5 volts to 7 volts, which is substantially dependent on the manufacturer of the mobile phone. A model of the mobile phone as described above can operate within a range of potential differences, and another model can operate in a different range. In a number of examples, the circumference may overlap; if the electronic device 112 includes a personal digital assistant or a knee t-type computer, it typically operates in a range of potential differences that differ from the mobile phone, for example, the range may be approximately 15 Volt to between 25 volts; therefore 1 sub-circuit 13. Signal Vp_ can be provided to power system 131 such that the Vpower is compatible with power system n i . The "contact probability" is a statistical probability that the system will allow power to be delivered to the electronic device 112 in relation to the vicinity of the power transfer surface 1Ua and relative to the predetermined position and orientation of the electronic device 112 = power transfer surface 111a. Contact Probability At least one contact 12〇 of the motor machine is in contact with the first voltage level*114, and the second contact 120 of the motor is in contact with the second material level "8 The probability that power can be delivered to the electronic device through the circuit. The contact probability is such that the geometry of the pads 114, 118 of the power wheel surface 111a separates the gap G of the first 16 201008056 voltage level pad 114 from the insulating region 119 of the second voltage level pad 118, And a function of the configuration of the plurality of contacts of the motor mechanism. It is expected that the contact 12 of the electronic device 112 can achieve 100% "contact probability" with the power transfer surface 11 la; therefore, the pad of the power transfer surface ma combined with the configuration of the contact 120 should be selected. The arrangement of 114, 118 and insulating region 119 is such that there is a 1% contact probability between electrical device 112 and power transfer surface 111a. Figure 5a is a device having an imaginary display such that a more detailed top view circle of the electronic device 112 carried by the power transfer fulcrum structure Π1 is visible. Here, the contact 12〇a is engaged with the pad 118b, and the contact 120b is engaged with the pad 118c; further, the contacts 12〇c and 120d are engaged with the pad 114b, and therefore, at the contact 12〇 There is no potential difference between c and 12〇d because they are joined to the same pad (ie, interface 114b), but 'relative to the contact! There is a potential difference between the contacts 120a and 120b of 20c and 120d because they engage different conductive regions (i.e., regions 116 and 117). In this manner, the contacts 12 are configured such that when they engage the surface U1a, at least two of the contacts are provided with a potential difference; it should be noted that if the device 112 is rotated at an angle of 0, it will still be satisfied. This condition. As will now be described, the satisfaction of this condition can be facilitated by the size of the selected contacts 12A and the regions 116, 117, and 119. Figure 5b is a more detailed top view of the power transfer surface 111a' for showing the insulating region 119 in more detail. Here, each of the pads (i.e., U4a, 118a, 114b, 118b, etc.) has a width dimension w, and The insulating region 119 has a width dimension G; therefore, the pads 17 201008056 included in the regions 116 and 117 are spaced apart from each other by a distance G. For example, the ns W circle I 〇a illustrates that the contacts 120 are preferably cylindrical, the diameter of each of the contacts is D and the distance between the contacts 12 〇 a and other contacts is about R_D, The angle between the points is further 'the distance between each adjacent pad in regions 116 and 117 is expressed as S' which is approximately equal to w+g. For the configuration of the four contacts as shown in Fig. 5a and 1〇&Φ^ί·-ΐ·4^β, it is preferable that the size R is smaller than or equal to the size W (RSW), so that the contacts The contact between i2〇a and 接鲁” 120 can be connected to the same interface in the area "6 or I"; and, preferably, the size R satisfies the following conditions: ?>|(^ + 2G) = |(S + G) The dimension D can have many different values, but is preferably selected to be a small 2G, so that the contacts in the contact 120 cannot be the areas ι 6 and ι 7 Connected in ~ up. In this manner, the contacts in the contacts 12A are unable to engage the regions ι 6 and 117 to form unwanted low resistance connections between the regions (i.e., % fins and, preferably, select dimensions) D has a value that increases its durability and steep 'life' and current handling capability. In order to be full, the dimension D is slightly smaller than the dimension G; and the vertical, =, yes, the size G is as large as possible. Maximizing the size G, and when G ' is such that: if = ir = | (fF + 2G), that is, W = 4G, or S = 5G, all other constraints can be met; moreover, D < G. In an example, when a grid spacing S is given, it can be found that if 18 201008056 G = 0_2S ' W = 0.8S ' R = 〇 .8S, and D < f) oc * and 1 The above conditions; however, in other situations, the size of the $, T, etc. may have different values. Moreover, if it is assumed that the contact area of the point 12G must completely contact the pads U4, 118, the contact portion partially contacting the insulating region g(1) is not regarded as a contact. Therefore, the system can ensure good, high quality by requiring the contact between the contact 120 and the voltage pads 114, 118 on the power transfer surface 111a to be fully contacted from 1 to 7 1. Power transmission connection. In order to achieve the above four connections

The contact probability of 1% of the point system, the size rule can satisfy the following conditions: R<W - D 5 and R>^{W + 2G + D) ° As described above, in order to optimize the system, The diameter D of the contact is smaller than the width of the insulating gap (D<G), so that the contacts cannot short the adjacent pads of different potentials; moreover, the diameter of the contacts should be as large as possible It is based on the premise to maximize durability, contact life and current handling. Furthermore, this will also result in a contact diameter D having a slightly smaller contact gap than the insulating gap G, which can be expressed as the fraction K of the gap G: D = KG, where KS1. Substituting D=KG into the above equation yields: R<W-KG > and 19 201008056 R>^(W + 2G + KG) » obtained by combining the equations: W-KG = ^(W + 2G + KG) > That is, W = (4 + 5K) G, or, S = (5 + 5K) G. In summary, when given the grid spacing S:

5 + 5K

R = 0.8S D=—K S .

5 + 5K For example, if K = 0.9, then:

G=0.10526S W=0.89472S R=0.80000S D=0.09474S. The following table is a list of the coefficients of s for other values of K: K 0 0.4 0.6 0.7 0.8 1.0 G 0.20000 0.14286 0.12500 0.11765 0.11111 0.1000 W 0.80000 0.85714 0.87500 0.88235 0.88889 0.9000 R 0.80000 0.80000 0.80000 0.80000 0.80000 0.8000 D 0.00000 0.05714 0.07500 0.08235 0.08889 0.1000 20 201008056 Two power delivery surfaces with different slot sizes but with the same spacing s can be placed; typically a power delivery surface with a larger gap size will be able to deliver more power, but smaller The gap size can still maintain the same or compatible voltage standard as the power delivery source; moreover, the contact diameter D for a power delivery source with a large gap size will be used for a smaller gap size The contact diameter D of the power transmission source is larger. If K and R remain fixed between the two systems, there will be a form of forward capacity. In this scenario, the low-power device will still achieve a β UK)% connection probability on the power transmission surface with large gaps;

And 'higher power devices will be incompatible with surfaces rated for lower power that will have a smaller gap size G. Since a larger diameter, high power device has a larger contact diameter D that can be larger than the gap size of the low power delivery surface, the more power device may be shorted across the electrodes of the two adjacent power delivery surfaces. - When the D system is directly controlled, the solution to the above equation will be reduced to the first set of equations defining the dimensions of the four contact systems shown in Figures 5a and 10a. For a diameter D of 00, the gap G can be as large as possible while maintaining a 100% contact probability. Figure 6a is a top plan view of an electronic system as a power delivery system in accordance with an implementation of the present invention. System 102 is for providing power to electronic device 112 in a power delivery surface that is referred to as surface nu", which system 1 is similar to system 101 described above and includes power delivery support structure 丨1丨, which also includes a conductive region 116 having a substrate contact 114, the region including a plurality of junction segments connected to the point 'm', and some of the segments of the segment 201008056 are represented as Pad segments 167, 168, and 169 'The first plurality of pad segments are connected to one another via individual wires 176 and 177. System 102 also includes a region 117 having a base contact 118 that includes a connection to a second plurality of pad segments of the contacts 118, and some of the interface segments of the pad segments are shown to be the pad segments 161, 162, and 163' the second plurality of pad segments They are interconnected by individual wires 174 and ι 75. The first and second plurality of pad segments are separated from each other by an insulating region 119, which is best viewed as indicated by the replacement arrow 144. In the enlarged part, conductive areas 116 and 117 and insulation Zone n9 defines surface 11 la'; as illustrated in Figures 6b through 6d, conductors 174, 175, 174', and/or 174 may define a portion of surface Ula'', or such conductors may not be on surface 111a". It should be noted that the substrate contacts Π 4 and 118 may have many different shapes such as curved or digonal; however, 'in this example, for the sake of brevity' they are shown as rectangles in shape. The pad segments 161, 162, © and 163 are also rectangularly shaped and have first and second opposing portions and first and fourth opposing portions, for example, the segment 162 has a first and a third Two opposing portions 170 and 171 and third and fourth opposing portions 172 and 173, the first portion 170 is connected to the second portion 171 of the adjacent pad segment 163 via the wire 175, and the second portion 171 is through the wire 174 is coupled to the first portion 17A of the adjacent pad segment 161, the portion 170 of the pad segment 163 is separated from the substrate contact 114 by the insulating region 119, and the portion 171 of the pad segment 161 is attached to the substrate. Contact 118. 22 201008056 Similarly, the pad segments 167, 168, and 169 are each rectangularly shaped and have first and second opposing portions and second and third opposing portions; for example, the pad segment 168 has a One and second opposing portions 17A, and 171', and third and fourth opposing portions 172, and 173, the first portion 170' is coupled to the second adjacent tab segment 167 via wire 175' The portion 171' and the second portion 171' are connected to the first portion 170' adjacent the interface segment 169 through the wire 174, and the pad segment 16 is coupled to the substrate contact 114. The beta wires U3a and 113b are connected to the base contacts 114 and 118 at one end and to the power adapter 18A at the other end, respectively. The wires 113a and 113b are included in the DC output line in; however, it should be noted that the wires 113a and 113b can be connected to other portions of the regions 116 and 117. The power adapter 180 is connected to the electrical plug 182 through the AC input line ι 81; in operation, the plug 182 is connected to the jack so that the potential difference can be supplied to the power adapter 18 through the input line 181, and the power transfer The device 180 steps down the potential difference and bypasses the output line 113 to supply it to the conductive regions 10 U6 and 117. In this way, the potential difference can be supplied to the surface 111a, so that it is operable to become a power transmission surface. Figures 6b to 6d are side views of the power delivery system 102 according to the present invention taken along the slit line 6-6, and showing different embodiments of the surface 1Ua". In Figure 6b, the pads 161 and 162 are Connected to the wires 1 to 4; in this example, the wires 174 and the pads 161 and 162 are flush with each other and define a portion of the surface 111 a". In FIG. 6b, pads 161 and 102 are connected together by wires 174; however, in this example, 23 201008056 wires 174 and pads 161 and 162 are not flush with each other; instead, wires 174 are Connected to the terminals 161 and 162 and extended through the branch structure iv, so that there is a gap 119 between the pads 161 and 162, therefore, the pads 161 and 162 define a part of the power transmission surface lua" and have wires 174 is adjacent to the power transmission surface 1Ua, wherein the wire 174 is connected to the pads i6i and 162 through the through holes 157a and 157b in the figure & the through holes 157 & and 1571) extend downwardly through a support structure 111 parallel to the surface uia"; the wire 174 extends through the support structure ln and is connected to the through holes 157 & 157b, and thus, the pads 161 and 162 define a portion of the power transmission surface Ilia", and the wire 174 is not Power transmission surface iiia". The power delivery system 1 〇〇 illustrated in Figures 2 and 6a and its various embodiments can be undesirably contacted with objects other than electronic devices; for example, 'key up, +, watch, f heavy Jewelry, or another electrically conductive object, can be placed over the power transfer surface. Because some objects of these objects can conduct current, they can affect the safety and performance of the system. In order to reduce the likelihood of this occurring, a non-conductive tape cover can be placed over the power transfer surface as will be explained so far. Figure 7a is a side view of a power delivery system i 〇 3 that can be similar to the systems 1 〇〇, 1 〇 1, and 1 〇 2 described above; however, in this embodiment, for illustrative purposes For the sake of reason, its system is similar to the power transmission system ι〇ι. In Fig. 7a, for the sake of simplicity, only pads 144a and 118a and contacts 120b and I20d are shown. The system 1〇3 includes a power transmission support structure 11 1 and a dielectric material region 127, and the region 127 is positioned on the surface 111a, 24 201008056, so that it can cover the conductive (four) 116*m and the insulating region ι 9 and operate as a non-conductive Cover of sex. One of the advantages of the dielectric material region 127 is that it protects the surface 111a such that the surface uia is highly unlikely to come into contact with an object that is not desired; another advantage is that it can also provide additional support for the device (1)' And protect the surface Ilia from wear and tear. The power transfer system for the implementation of the dielectric layer 127 is completed via capacitive dissipation. The geometry of the device contacts (3) and the power transfer surface pads 114, 118 for conductive light bonding are almost identical to those used for direct conductive connections. The geometry β (four) requirements are the same. For embodiments of conductive transitions, some of the surface pads of the surface are maintained at a polarity while the remaining surface pads are maintained at a second polarity. When having an electrically conductive connection, it is desirable that at least one of the contacts 120 is over a pad U4, 118 of a polarity, while the second contact is simultaneously over the pads 114, 118 of the second polarity; For capacitive coupling, the contacts 120 can simultaneously overlap on the two surface pads 114' 118 of different polarities to a minimum extent without the opposite result. In operation, the electronic device 112 is carried by the power delivery support structure 111 over the surface 127a of the region 127; therefore, the contacts i20b and 120d engage the surface 127a such that they are separated from the contact pads 114a and 118b by the region 127, respectively. Separately, in the displayed position, there is a capacitance between the contact 120b and the pad n4a, and between the contact 12〇d and the pad U8a. Typically, the contacts 120 and the conductive regions 116 and 117 are selected such that at least two capacitors are formed when the surface 127a is joined; the contacts 12 are configured such that the two capacitor systems are formed independently of the angle. Figure 7b is a schematic illustration of a circuit 13 in accordance with the present invention, including the capacitors of the above 25 201008056. The circuit i 30 also includes a circuit 130 as described with respect to FIG. 4, and an AC power source 134 (Vinpp) coupled to contacts 120b and 120d via capacitors 135a and 135b, respectively; however, it should be noted that power source 134 It can be connected between other contacts in the contact 12〇, and the use of the contacts 120b and 120d here is for illustrative purposes only. The power source I" represents the potential difference provided by the power transmission surface, so that the power source 134 is connected between the contacts having a potential difference in the contact 120. Referring to Figure 7a, the capacitor i35a (Cl) corresponds to a portion of the power. The dielectric material region 127 has a contact 120b and a pad 114a therebetween, and the capacitor 13 51) (02) corresponds to a contact 120d and a pad 118a having a portion of the dielectric material region 127 therebetween. Note that the capacitor 135a And 135b are connected in series 'when their capacitance increases, the impedance of capacitors 135 & and 1351) decreases; conversely 'when their capacitance decreases, the impedance of capacitors 135a and 135b increases" because power supply 134 provides an AC signal, So, it is desirable that capacitors 135a and 135b have low impedance such that they are operable to become a low impedance current path (i.e., short circuit) and that more Ac power can be charged through region 127. The capacitance of 135a and 135b depends on a number of different factors such as the thickness ti of region 127 and the type of dielectric material contained in region 127; preferably, the thickness t! should be small. And the dielectric material should have a high dielectric constant (er), so that the capacitance of the capacitors 135a and 135b becomes large and the corresponding impedance becomes small. Examples of suitable dielectric materials include rubber 'silicon-based resin, plastic, cloth, ceramics The other factor affecting the capacitance of the capacitors 135a and 135b is the dimension D of the contacts 120 26 201008056 and the size w of the pads 114 and 118; when the dimensions increase, the capacitance is generally increased. "The capacitance of the capacitor 135a is also based on The capacitance between the contacts i2〇b and the pads 114a is determined, and the capacitance of the capacitor 135b is also determined according to the overlap between the contacts 120d and the pads 118a; therefore, the capacitances of the capacitors 135a and l35b are based on the angle Depending on φ, when the amount of overlap between the contact 12 and the pad 11 4a increases, the capacitance of the capacitor n5a increases, and decreases when the amount of overlap between the contact 12 〇b and the pad 114a decreases; Further, when the amount of overlap between the contact 120d and the pad U8a is increased ❹, the capacitance of the capacitor 135b is increased, and is reduced when the amount of overlap between the contact 120d and the pad 1 i8a is reduced. Yes, There are values of G, W, D, and S, which are generated to > as large as the full overlap of all angles 0 on the surface 11la. The size G can be adjusted so that a contact is attached Above the gap 119'. In this manner, there will always be a contact having a capacitance; when the size G is increased, the size D may also be increased, so that the current carrying capacity of the contact is increased. Like the circuit shown in Fig. 7b 130, which can be analyzed according to the electrical properties of the circuit components. The attached circuit elements include: Q (charge) ' ε r (relative dielectric constant) ' ε 〇 (vacuum permittivity), ti (dielectric thickness), Vinpp (AC power supply 134) ' v〇ut (at 133a and 133b Between the measured voltage), C! (capacitor of capacitor 135a), and C2 (capacitor of capacitor 135b); other important variables include the area of contact with the power supply source (A), and the contact surface Directly obtained (D). For systems with 100% contact probability, the geometry will ensure that the electrical device contacts forming the plates of one of the capacitors will not be smaller than the device contacts due to overlapping regions of the single device contacts. Area; therefore, it can be assumed that C1=C2=capacitance. Since C1 and C2 are connected in series, the equivalent capacitance (Ceq) is half of Cl, as shown below:

The charge Q from each cycle of the AC power supply to the output vout is obtained by:

The area of the contact that can make contact with the power transmission source is obtained by the following equation: A — ~nD2 » 4 The capacitance of the contact with the area A defined above is taken by the following formula: c = -0~Sr ~, so Γ — £〇Sr^ . ^eq----, therefore 'when the frequency f is excited, the current (I) can be written as: I = 2(KPP-vout)Ceqf =2(,_^) Learn / = (V. -V ί£〇£^°2 , inpp r out ) Z_^--- 4ί, one order J such as 'for 19 mm (mm) grid spacing and 3.8 mm (mm) Contact diameter (D) '11 relative dielectric constant (er) and 0.2 mm (mm) 28 201008056 insulator barrier thickness (tl), 5 volts (v) of VQUt, 200 volts (V)

The contact 120 is configured such that it can align with the corresponding opening and extend through the openings 153 to engage the surface 11 la (Fig. 8b). In other examples, the 'contact 12' is movable such that The distance between the contacts 12 can vary.

The opening 153 is tapered In part, the contact 12〇 will move as indicated by the moving arrow () (Fig. 8a) such that the contact 12〇 is preferably aligned with the opening 153'. In this manner, when the contact 12G engages the cover 151, At the same time, the contact 12〇 can be aligned with the opening p 153. It should be noted that the contact 12() can be moved in many different ways, some of which will be shown in Figures 19 to 19f and Figure 20a. To 20f to explain. In some examples, the cover 151 is removably attached to the power delivery support structure in a repeatable manner; in other examples, the cover is randomly positioned over the llla such that it is Retreat from the surface 30 201008056

In this embodiment, the mobile phone 110 includes a housing 195 having an opening 123 extending therethrough and into the battery compartment 126. The battery compartment 126 can house a power system ;3ι; in this example, the power system 131 is a rechargeable battery. Power system 31 201008056 The system 131 is repetitively inserted into and removed from the battery compartment 126, as shown in Figures 9a and 9b, respectively; when the power system ι31 is inserted into the battery compartment 126, The contacts 139a and 139b engage the contacts 133a and 133b (Figs. 3 and 4) of the circuit 130, respectively, such that signals can flow between the contacts. The mobile phone 110 also includes a contact 12 that extends through the housing 195: in this example, when the device 112 is carried by the power delivery support structure η, the housing 195 is coupled to the power transfer surface by the contacts 120. Interspersed. The ® contact 120 includes four contacts' as shown above as contacts 12A, 120b, 120c, and 120d. It should be noted that in other examples, another number of contacts, such as five or six, may be included, and the contacts may be configured in many different ways, some examples of which will be illustrated 1〇& and 1 Ob are explained. The number of such contacts and the particular configuration are based on a number of different factors such as the configuration of conductive regions 116 and 117. In accordance with the present invention, the housing 195 of the device 112 has been modified such that the joint 120 extends through the housing 195 and extends outwardly from the surface n2a, which corresponds to the outer surface of the housing 195. In this manner, the contact 112 is carried and integrated with the device 112; in this example the mobile phone 110 also includes and carries the circuitry 13A, but for the sake of brevity, this is not shown. In this example, circuit 130 is positioned within housing 195, but in other examples it can be positioned external to housing 195. An example of a circuit 13A positioned outside the casing 195 will be described with reference to Figures i6a and (10), and an example positioned within the casing 195 will be described herein. Figure 9c is an exploded top perspective view of the housing 195 and the contacts 12A. In the example of 32 201008056, the housing 195 has been modified by the formation openings 136a, 136b, 136c, and 136d.

The wires connecting the circuit 130 to the contacts 120 can be positioned in a number of different ways, such as the wires can pass through the power delivery support structure 137 or across its outer periphery 137C and between the faces 137 & and U7b, but this For the sake of brevity, the wires are not shown. Figure 10a is a top plan view showing a configuration of contacts 12 in accordance with the present invention. In this example, the contacts 120 are configured such that the contacts 12A are centered at the location 124, and the locations 124 are centrally disposed within the imaginary circle, and the imaginary® 125 has a radius R and is only for reference The purpose is included herein to show that the contacts 120 are positioned relative to each other and relative to the position Η#. The contacts 12013, 120 (;, and 120 (! are positioned above the virtual ® 125 at a distance of about 11_(〇/2) 33 201008056 from the position 124, and are spaced apart from each other. In this example, there are two The contacts are above the circle 125 and they are equidistantly spaced from each other; therefore, there is an angle 61 of about 120 degrees relative to the position 124 between the contacts, between the contacts 120b and 120d. The angle Θ is shown in Figure 1a. It should be noted that the $ is based on the number of contacts positioned above the circle 125, as illustrated by 囷l〇b and 10c; The contacts 12〇b, 12〇c, and 12〇 (1 can be positioned at other distances from the position 124 such as the distance R. In this example, the contacts 120 are cylindrical in shape and each have a diameter D The diameter D is selected such that it is smaller than the dimension G of the insulating region 119 (Figs. 5a and 5b). The radius R and the diameter D are selected such that when the contact 12 is joined to the surface 111a, at least one of the contacts is connected. The point system is joined to the conductive region 116 and at least one other of the contacts is bonded to the conductive region 117. In this manner, 'as described above, Between at least two junctions of the contacts having a potential difference in contact 〇2〇, and providing power to the power system 131. Preferably, the configuration of the contacts 120 is as shown in FIG. Used in conjunction with the configuration of conductive regions 116 and π 7. Figures 10b and 10c are other examples of the configuration of contacts 12, and 12", respectively, and contacts 12 〇' contain five contacts And the contact 12 〇, which comprises six contacts. In Figure i〇b, there are four contacts represented as contacts 1201) to 12〇e, which are positioned on the imaginary circle 125 and the distance position丨24 is approximately R-(D/2) and equidistantly spaced from each other; in Figure 1 〇c, there are five contacts represented as contacts 120b to 120f, which are positioned on the imaginary circle 125 And spaced apart from one another and spaced apart by a distance from position 124 about 34 201008056 R-(D/2). In Figures l〇b and 10c, the contacts on circle 125 are equidistant from each other Intersected such that the angles are approximately 90 degrees and 72 degrees, respectively; in this manner, the angle 0 is determined by the number of contacts positioned on the circle 125, preferably The configuration of the contacts 120' and 120" is used as shown in Figure 6 with the configuration of the conductive regions 116 and 117. It should be noted that 'in Figures 10a to 10c, for the purpose of descriptive purposes, Point 120a is shown to be centrally disposed within the imaginary circle 125, and in other examples, it can be positioned above the circle 125. ❹ Figure 1-3 to three of the embodiments showing the implementable contact configuration Example 'Other contact configurations can be used in a wide variety of embodiments, and other contact configurations can also permit 100% contact probability. The contact arrangement shown in Figures l〇a to l〇c achieves a 100% contact probability even when the individual contacts are offset from the true desired position up to the diameter of a joint. 11a and lib are perspective views of contacts 120' and 120" respectively carried by the mobile phone no and integrated with the mobile phone 110. Here, the contact 120 of the mobile phone is already at the corresponding contact 120. And 12 〇, to replace, in these examples, the housing 195 has been modified as taught in Figure 9c such that the contacts 120, and UO" pass through the housing 195 and extend outwardly from the surface n2a. It is useful if the interface between the contacts 12A, and the interface between the UO" and the housing 195 is hermetically sealed to reduce the flow of wet air into the housing 195. Note that the number of openings 136 It depends on the number of contacts; therefore, in these examples, five and six openings are formed through the housing 195 and formed separately in Figures 11 & and Ub. In shape, the contacts 12〇 12〇, and 35 201008056 12 0′′ are formed in a cylindrical shape; however, it should be noted that they may have other shapes as will now be described. Figures 12 & and 12b are side and perspective views, respectively, of an embodiment having contacts of different shapes. The shapes can be selected based on a number of different factors, such as the shape of the power transfer surface, and the desired current flow between the power transfer surface and the contacts. The power transmission surface having different shapes is illustrated in Fig. 3. The current flow depends on the shape of the power transmission surface and the shape of the joint, because these factors affect the joint between the contact and the power transmission surface. The area, and therefore, affects the resistance between them. In these examples, contacts 210 and 212 have rounded and rectangular ends 211 and 213, respectively, such that contacts 210 are cylindrical and contacts 212 are tied to the cube.
