     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to charging devices, and particularly to wireless charging devices. 
     2. Technical Background 
     Portable or hand-held electronic devices have become ubiquitous. Moreover, the communications and computing technology spaces over-lap with modern cell phones and lap-tops, tablets and I-pads having much of the same. One reason that these devices are so popular relates to the fact that they can be carried and used by the user almost anywhere. Thus, a user can make telephone calls, send and receive emails, exchange text messages and/or browse the internet on the fly. In order to support such device mobility, each of these portable electronic devices must include some type of rechargeable battery system (e.g., electrochemical batteries, capacitor batteries, etc.). As a result, there is an urgent need in the market for battery recharging stations. 
     In one approach that has been considered and tried, many electronic devices are commercialized and sold together with their own charging means. To be specific, many charging devices of this type are configured as an electrical power cord that has a set of electrical contacts disposed in a DC output plug that has a form factor configured to mate with a corresponding charging receptacle formed in the portable device. The charging cords (or stations) of this type are configured to be connected to an AC power source (e.g., 120 VAC) and convert the AC power into a low voltage DC signal that charges the battery. One drawback to this approach is that the charging cord/station is only usable with that particular device. Thus, its unique DC interface cannot be used with any of the other portable devices on the market because they have charging receptacles with a different form factor. As a result, when one of the charging station or the portable device gets damaged or has reached end of life, both have to be replaced. 
     In another approach that has been considered, a portable charging station includes an AC power connection (that couples the device to AC power) and is further equipped with one or more standardized low voltage ports (e.g., USB ports). While the portable electronic device is also equipped with a standardized low voltage port, it may not necessarily have the same form factor or configuration. In either case, the user must obtain a low voltage cord that is appropriately terminated on each end to charge the device. That cord must then be stowed when it is not in use. While this approach goes a long way toward solving the universality issue, it does not totally solve the problem; the so-called standardized low voltage ports actually comprise a family of low voltage port standards. One drawback to this approach therefore relates to the user&#39;s accumulation of low voltage cords over time. (One for each type of portable device in his possession). Many users will reach into a drawer for the “right” low voltage cord, only to pull out a plurality of tangled cords that must be separated. Once the cords are separated, the user must “eye-ball” the various cords and select the right one for the device he is seeking to charge. As a result, these charger types are susceptible to being misplaced, lost or stolen. 
     Perhaps as a result of the aforementioned issues, many portable charging stations now include “wireless power transfer technology” that eliminates the need for a low voltage interconnection cable. Specifically, a device is charged using wireless magnetic inductive coupling; the charging station includes a coil winding and the portable electronic device is equipped with a secondary coil. The two coils form a transformer. Charging occurs when the portable electronic device is brought within range of the charging coil&#39;s magnetic field. While this approach simplifies the cord entanglement issue, it also presents other drawbacks. While the low voltage cable is eliminated, the charging station still requires an AC power cord and further requires a charging cradle that positions the mobile device proximate the charging coil. Thus, the resultant charging station is bulky and unwieldy, making it inconvenient to cart around and stow. Moreover, wireless charging stations are also susceptible to being misplaced or stolen. 
     These various approaches all require that the charging device have a power plug to receive power. Another problem arises when the power is derived from an electrical wiring device which is a class of devices installed in an outlet box as part of an electrical distribution system. When the charging station is plugged into the electrical wiring device, that particular voltage port is no longer available for any other use. Also, the power plug or the charging device itself obscures the face of the wiring device, effectively taking part of the wiring device out of service.

     As embodied herein, and depicted in  FIG. 1A , a front isometric view of an electrical wiring assembly  100  in accordance with an embodiment of the invention is disclosed. The electrical assembly includes a wall plate assembly  30  that is configured to accommodate an electrical wiring device  10  and an antenna assembly  20  (not shown in this view). The wall plate assembly  30  includes an integrally formed wall plate  30 - 1  that further includes an electrical wiring device wall plate portion  30 - 2  and an antenna assembly wall plate portion  30 - 3 . The integrally formed wall plate also includes a side wall  30 - 4  that has a substantially triangular (in actuality, it has a pentagonal shape; two of the minor sides function as stand-offs); i.e., it includes a first major side that is configured to abut a wall surface and a second major side that extends at an angle so that the antenna wall plate portion  30 - 3  is inclined. 
     The wall plate assembly  30  also includes a device cradle  30 - 10  that includes a cradle pad  30 - 100 . The cradle pad  30 - 100  is comprised of a material that has a relatively high coefficient of friction. An antenna logo plate  30 - 6  is disposed on the antenna assembly wall plate portion  30 - 3  within a recessed portion ( 30 - 60 ). The plate  30 - 6  is also comprised of a material that has a relatively high coefficient of friction. Thus, a portable electronic device under charge that is resting in the cradle  30 - 10  and propped against the antenna wall plate portion  30 - 3  will remain in place (due to the frictional forces exceeding gravitational forces). 
     The electrical wiring device wall plate portion  30 - 2  has an opening  30 - 20  formed therein to accommodate the electrical wiring device  10 . According to the present invention, an electrical wiring device may be configured as an outlet receptacle or as a protective device, such as a ground fault circuit interrupter (GFCI), an arc fault circuit interrupter (AFCI), a transient voltage surge suppressor (TVSS), or a surge protective device (SPD). Other electrical wiring device examples include dimmers, fan speed controls, night lights, low voltage ports, or USB ports. Finally, each of these wiring device types may be found in mix-and-match combinations with other kinds of these wiring devices. For example, a GFCI/AFCI combination device may be included within a single housing. The example in  FIG. 1A  shows an outlet receptacle and a USB combination. 
     Referring to  FIG. 1B , a rear isometric view of the electrical wiring assembly  100  depicted in  FIG. 1A  is disclosed. The electrical wiring device  10  is shown extending through the opening  30 - 20  so that the wiring terminals are accessible for AC wiring. In practice, the electrical wiring device  10  is mounted to a single gang device box via the mounting ears  10 - 12  after the AC wiring is connected to the wiring terminals. In this embodiment, the electrical wiring device includes a pair of  15 A/ 20 A receptacles  10 - 6  and a pair of USB ports  10 - 8  for charging the portable device by way of cord terminated with a USB plug when inserted in one of the ports  10 - 8 . The USB ports  10 - 8  are powered by an AC/DC converter circuit inside electrical wiring device  10  (not shown). A DC power cord  40  is coupled to the AC/DC converter via an opening in the side of the electrical wiring device  10 . The opposite end of the cord  40  includes a plug that is configured to be inserted into the antenna plug opening  20 - 20  disposed at the top end of the antenna back body  20 - 2 . In an alternate embodiment, the wiring device  10  has a socket in its side wall that is coupled to the AC/DC converter and cord  40  includes plugs at both ends for interconnecting the two sockets (not shown.) In another embodiment, cord  40  passes through an opening in antenna back body  20 - 2  and is terminated with a plug that mates with a socket in wiring device  10 . 
     Of course, the antenna back body  20 - 2  is configured to form a rear volume together with the antenna wall plate portion  30 - 3  and the side wall  30 - 4 . Moreover, the antenna back body  20 - 2  is configured to be connected to the inside of the antenna wall plate portion  30 - 3  to complete the antenna assembly  20  enclosure. 
     Note that the portable device cradle  30 - 10  is coupled to a ratchet member  30 - 8  on each side thereof. The ratchet members  30 - 8  allow the cradle  30 - 10 —and hence the portable device  1 —to be adjusted up or down so that the antenna coil in the antenna housing  20 - 2  substantially aligns with the antenna coil disposed in the portable device  1 . Specifically, each ratchet  30 - 8  is disposed within a recess  20 - 22  formed in a side portion of the antenna back body  20 - 2 . Each ratchet  30 - 8  also includes a catch element  30 - 80  disposed on the ratchet  30 - 8  end opposite the cradle  30 - 10 . The catch member  30 - 80  is configured to move between the ratchet steps  20 - 24  that are formed in the ratchet recess regions  20 - 22 . 
     Referring to  FIG. 1C , a front isometric view of the electrical wiring assembly  100  depicted in  FIG. 1A  is disclosed with a portable electronic device in a charging position. This view is identical to  FIG. 1A  with the exception that a portable device  1  (e.g., a cell phone) is shown resting on the cradle  30 - 10 . 
     Referring to  FIG. 1D , a side elevation view of the electrical wiring assembly  100  depicted in  FIG. 1A  is disclosed. In this view, a portable electronic device is shown in the charging position. As noted above, the side wall  30 - 4  has a substantially triangular (again, it actually has a pentagonal shape; but two of the smaller sides function as stand-offs) shape; thus, the antenna wall plate  30 - 3  is inclined at an angle θ relative to the substantially vertical wall surface. The angle θ may be within a range substantially between 0° and 20°. Referring to  FIG. 1E , another side elevation view of the electrical wiring assembly  100  depicted in  FIG. 1A  is disclosed. Again, the portable electronic device is shown in the charging position. 
     As embodied herein and depicted in  FIG. 1F , an exploded view of the electrical wiring assembly  100  depicted in  FIG. 1A  is shown. This view shows with more clarity the wall plate  30 - 1  that further includes an electrical wiring device wall plate portion  30 - 2  that is integrally formed with the antenna assembly wall plate portion  30 - 3 . The wall plate portion  30 - 3  includes a recessed region  30 - 60  that is configured to accommodate the antenna bearing plate  30 - 6 . The antenna housing  20 - 2  includes a circuit assembly  20 - 1  that is disposed within the space formed by the antenna back body member  20 - 2  and the interior wall of plate  30 - 3 . The antenna housing  20 - 2  is further protected by the side wall  30 - 4 . 
     The circuit assembly  20 - 1  includes a printed circuit board (PCB)  20 - 4 . The PCB  20 - 4  includes various control circuits (not visible in this view) disposed on the back side thereof. The front side includes a shielding structure  20 - 6  that accommodates a single antenna coil  20 - 10 . The shielding structure  20 - 6  prevents a magnetic field from heating any metallic structures behind the assembly  100  (e.g., a metallic device box or electronic components). The PCB  20 - 4  also includes a plug receptacle  20 - 40  that is configured to accommodate the plug from the DC supply cord  40 . Specifically, the DC supply cord will provide a DC supply voltage (e.g., +5 DCV) for the antenna coil and the control circuitry. 
     The other components of the assembly  100  were described above in detail and thus any further description would be repetitive and superfluous. 
     Referring to  FIGS. 2A-2E , side elevation views of the electrical wiring assembly  100  depicted in  FIG. 1A  are shown to illustrate the adjustable ratcheting mechanism  30 - 8 . In these views, the distance between the bottom of the wall plate  30 - 1  and the top surface of cradle  30 - 8  is shown as dimension “x”. The dimension x can be made to vary depending on the size of the portable electronic device  1  disposed on the cradle. In other words, in a single antenna coil embodiment, the user may desire to adjust the x dimension so that the primary and secondary coils (i.e., the charger coil  20 - 10  and the portable device coil) are in close proximity to each other. 
     As embodied herein, and depicted in  FIG. 3A , a front isometric view of an electrical wiring assembly  100  in accordance with an embodiment of the invention is disclosed. As before, the electrical assembly  100  includes a wall plate assembly  30  that is configured to accommodate an electrical wiring device  10  and an antenna assembly  20  (not shown in this view). The wall plate assembly  30  includes an integrally formed wall plate  30 - 1  that is configured to include an electrical wiring device wall plate portion  30 - 2  and an antenna assembly wall plate portion  30 - 3 . The integrally formed wall plate  30 - 1  also includes a side wall  30 - 4  has a substantially triangular shape so that the antenna wall plate  30 - 3  is inclined. The electrical wiring device wall plate portion  30 - 2  has an opening  30 - 20  formed therein to accommodate the electrical wiring device  10 . 
     The wall plate assembly  30  also includes a device cradle ledge  30 - 12  that again includes a cradle pad  30 - 100 . The cradle pad  30 - 100  is comprised of a material that has a relatively high coefficient of friction. As before, the antenna logo plate  30 - 6  is disposed on the antenna assembly wall plate portion  30 - 3  within a recessed portion ( 30 - 60 ). The plate  30 - 6  is also comprised of a material that has a relatively high coefficient of friction. Thus, a portable electronic device under charge that is resting in the cradle ledge  30 - 12  and propped against the antenna wall plate  30 - 3  will remain in place (due to the frictional forces exceeding gravitational forces). As described below, the antenna housing includes three primary coils that are configured to provide a more robust magnetic field, thus the need for an adjustable cradle is eliminated. 
     Referring to  FIG. 3B , a rear isometric view of the electrical wiring assembly depicted in  FIG. 3A  is disclosed. The electrical wiring device  10  extends through the opening  30 - 20  so that the wiring terminals are accessible for AC wiring. During installation, the electrical wiring device  10  is mounted to the device box via the mounting ears  10 - 12  after the AC wiring is connected to the wiring terminals. In this embodiment, the electrical wiring device includes an AC/DC converter circuit (not shown). A DC power cord  40  is coupled to the AC/DC converter via an opening or a socket in the side of the electrical wiring device  10 . The opposite end of the cord  40  includes a plug that is configured to be inserted into the antenna plug opening  20 - 20  disposed at the top end of the antenna back body  20 - 2 . The antenna back body  20 - 2  is configured to form a rear volume together with the front antenna wall plate portion  30 - 3  and the side wall  30 - 4 . Moreover, the antenna back body  20 - 2  is configured to be connected to the inside of the antenna wall plate portion  30 - 3  to complete the antenna assembly  20  enclosure. 
     Referring to  FIG. 3C , a side elevation view of the electrical wiring assembly  100  depicted in  FIG. 3A  is disclosed. In this view, a portable electronic device is shown in the charging position. The antenna wall plate  30 - 3  is again inclined at an angle θ relative to the wall surface by virtue of the shape of the side wall  30 - 4 . The angle θ may be within a range substantially between 0° and 20°. Referring to  FIG. 3D , another side elevation view of the electrical wiring assembly  100  depicted in  FIG. 3A  is disclosed. Again, the portable electronic device is shown in the charging position. 
     Referring to  FIG. 3E , an exploded view of the electrical wiring assembly  100  depicted in  FIG. 3A  is disclosed. This view shows the wall plate  30 - 1  with more clarity. Again, the electrical wiring device wall plate portion  30 - 2  is integrally formed with the antenna assembly wall plate portion  30 - 3 . The wall plate portion  30 - 3  includes a recessed region  30 - 60  that is configured to accommodate the antenna bearing plate  30 - 6 . The cradle ledge  30 - 12  is disposed along the bottom edge of plate  30 - 3 . 
     The antenna housing  20 - 2  includes a circuit assembly  20 - 1  that is disposed within the space formed by the antenna back body member  20 - 2  and the interior wall of plate  30 - 3 . The antenna housing  20 - 2  is further protected by the side wall  30 - 4 . 
     The circuit assembly  20 - 1  includes a printed circuit board (PCB)  20 - 4 . The PCB  20 - 4  includes various control circuits (not visible in this view) disposed on the back side thereof. The front side includes a shielding structure  20 - 6  that accommodates a plurality of antenna coils  20 - 10 . The shielding structure  20 - 6  prevents a magnetic field from heating any metallic structures behind the assembly  100  (e.g., a metallic device box or an electronic component). In the example shown in this view, the antenna is comprised on three coils ( 20 - 10 - 1 ,  20 - 10 - 2 , and  20 - 10 - 3 ). Again, the PCB  20 - 4  also includes a plug receptacle  20 - 40  that is configured to accommodate the plug from the DC supply cord  40 . Specifically, the DC supply cord will provide a DC supply voltage (e.g., +5 DCV) for the antenna coil and the control circuitry. 
     As embodied herein and depicted in  FIG. 4A , a front isometric view of an electrical wiring assembly  100  in accordance with another embodiment of the invention is disclosed. In this embodiment the electrical assembly  100  includes a wall plate housing assembly  300 . The wall plate housing assembly  300  includes a back body sub-plate  300 - 2  coupled to a single wall plate cover  300 - 4  to form the wall plate housing assembly  300 . The electrical wiring device  10  and the antenna assembly  20  (not shown in this view) are substantially disposed within the housing  300 . Note that the rear portion of the electrical wiring device is open at the rear to allow for access to the AC wiring terminals  10 - 14 . The back body sub-plate  300 - 2  includes a side wall that has a substantially triangular shape so that the entire wall plate cover  300 - 4  is inclined relative to the mounting (wall) surface. The wall plate cover  300 - 4  has an opening  300 - 20  formed therein to accommodate the electrical wiring device  10 , and a recessed portion  300 - 60  configured to retain the antenna logo plate  300 - 6 . 
     The wall plate cover  300 - 4  also includes a device cradle ledge  300 - 12  at least below the antenna assembly  20  end of wall plate cover  300 - 4  and a cradle pad  300 - 14 . The antenna logo plate  300 - 6  is disposed on the wall plate cover  300 - 4  within a recessed portion ( 30 - 60 ) for identifying the position of the antenna assembly  20  within the housing  300 . The plate  300 - 6  is comprised of a material that has a relatively high coefficient of friction for the reasons provided above. As described below, the antenna housing includes three primary coils that are configured to provide a more robust magnetic field, thus the need for an adjustable cradle is eliminated. 
     Referring to  FIG. 4B , a rear isometric view of the electrical wiring assembly  100  depicted in  FIG. 4A  is disclosed. The electrical wiring device  10  extends through the opening  300 - 20  into recessed region  300 - 20 - 1  so that the wiring terminals  10 - 14  are accessible for AC wiring. As before, the electrical wiring device  10  is mounted to the device box after the AC wiring is connected to the wiring terminals  10 - 14 . 
     Referring to  FIG. 4C , an exploded view of the electrical wiring assembly depicted in  FIG. 4A  is disclosed. The wall plate housing  300  is shown to include a rear sub-plate  300 - 2  that includes an electrical wiring device portion and an antenna housing portion  300 - 24 . The electrical wiring device portion is shown to include the device opening  300 - 20  and the rear recessed region  300 - 20 - 1 . The antenna housing portion  300 - 24  takes the place of the antenna back body  20 - 2  used in the previous embodiments. In other words, the antenna assembly  20  is disposed directly within the housing compartment  300 - 24 . The front wall plate cover  300 - 4  is disposed over the sub-plate frame  300 - 2  to complete the enclosure. Like previous embodiments, the front cover  300 - 4  includes a recessed region  300 - 60  that is configured to accommodate the antenna logo plate  300 - 6 . A cradle ledge  300 - 12  is disposed along at least a portion of the bottom edge of the front cover  300 - 4 . 
     The antenna housing  20 - 2  includes a circuit assembly  20 - 1  that is disposed within the space formed between the housing compartment  300 - 24  and the interior wall of the front wall plate cover  300 - 4 . The circuit assembly  20 - 1  includes a printed circuit board (PCB)  20 - 4  that has various control circuits (not visible in this view) disposed on the back side thereof. The front side includes a shielding structure  20 - 6  that accommodates a plurality of antenna coils  20 - 10 . The shielding structure  20 - 6  prevents a magnetic field from heating any metallic structures behind the assembly  100  (e.g., a metallic device box or an electronic component). In the example shown in this view, the antenna is comprised on three coils ( 20 - 10 - 1 ,  20 - 10 - 2 , and  20 - 10 - 3 ). As before, the PCB  20 - 4  also includes a plug receptacle  20 - 40  that is configured to accommodate the plug from the DC supply cord  40 . Specifically, the DC supply cord will provide a DC supply voltage (e.g., +5 VDC for the antenna coil and the control circuitry). Note that the electrical wiring device in  FIG. 4C  does not include USB ports  10 - 8 . While the high voltage to low voltage (i.e., AC/DC, AC/AC or DC/DC) converter circuitry can provide low voltage to both the USB ports  10 - 18  and the antenna assembly, it need not provide the USB ports  10 - 18 . This optional embodiment is depicted in  FIG. 4C  and elsewhere in the drawing Figures. 
     Referring to  FIG. 5A , a front isometric view of an electrical wiring assembly in accordance with another embodiment of the invention is disclosed. In this embodiment, the electrical assembly  100  includes an antenna wall plate assembly  30  that is arranged vertically. To be specific, the wall plate assembly  30  includes a wall plate  30 - 14  that is coupled to that antenna back plate  20 - 2  by a hinge element  30 - 144 . The antenna assembly  20  is disposed between the antenna back plate  20 - 2  and the antenna wall plate  30 - 3 . In one embodiment, the antenna wall plate assembly  30  is configured to rotate outwardly from a position that is substantially flush with the wall surface so that it is inclined at an inclination angle θ relative to the wall surface. The inclination angle θ is within a range between 0° and about 20°. In another embodiment, the antenna wall plate assembly  30  rotates from a closed “stowed” position where the assembly substantially hides wiring device  10  to an open “in use” position where the antenna wall plate assembly  30  is inclined at an inclination angle θ relative to the wall. In this embodiment, the antenna wall plate assembly  30  rotates downwardly by an angle φ so that it is inclined at an inclination angle θ relative to the wall surface. Thus, the rotation angle φ is within a range between 0° and about 160°. Thus, as one might expect, the sum of the angles θ, φ should be about 180°. 
     The antenna wall plate  30 - 3  again includes a device cradle ledge  30 - 12  that again includes a cradle pad  30 - 100 . The cradle pad  30 - 100  is comprised of a material that has a relatively high coefficient of friction. As before, the antenna logo plate  30 - 6  is disposed on the antenna wall plate  30 - 3  within a recessed portion ( 30 - 60 ). The logo plate  30 - 6  is also comprised of a material that has a relatively high coefficient of friction. Thus, a portable electronic device under charge that is resting in the cradle ledge  30 - 12  and propped against the antenna wall plate  30 - 3  will remain in place (due to the frictional forces exceeding gravitational forces). As described below, the antenna housing  20 - 2  includes three primary coils that are configured to provide a more robust magnetic field, thus the need for an adjustable cradle is eliminated. 
     Referring to  FIG. 5B , a rear isometric view of the electrical wiring assembly depicted in  FIG. 5A  is disclosed. The electrical wiring device  10  extends through an opening in the electrical wiring device wall plate  30 - 14  so that the wiring terminals are accessible for AC wiring. Again, the electrical wiring device  10  is mounted to the device box by the mounting ears  10 - 12  after the AC wiring is connected to the wiring terminals. In this embodiment, the electrical wiring device includes an AC/low voltage converter circuit (not shown) so that a low voltage power cord  40  can be connected between the electrical wiring device  10  and the antenna wall plate assembly  30 . The rear view of  FIG. 5B  clearly shows that antenna assembly mounting hinge  30 - 144  is coupled between the antenna back plate  20 - 2  and the lower mounting ear  10 - 12 . 
     Referring to  FIG. 5C , a front isometric view of the electrical wiring assembly  100  depicted in  FIG. 5A  with a portable electronic device  1  in a charging position is disclosed.  FIG. 5D  is a side elevation view of the electrical wiring assembly  100  depicted in  FIG. 5C ; i.e., the electrical wiring assembly  100  is shown with the portable electronic device in the charging position. 
     Referring to  FIG. 5E , an exploded view of the electrical wiring assembly depicted in  FIG. 5A  is disclosed. As shown, the hinge element  30 - 144  is coupled between the mounting ears  10 - 12  and the antenna back body  20 - 2 . The slots  20 - 26  formed in the back body  20 - 2  accommodate hinge element  30 - 144 . The antenna back body also includes a gap  20 - 20  that accommodates the plug  40 - 1  of the low voltage cord  40  so that it can readily engage the female low voltage receptacle  20 - 40  disposed on the low voltage PCB  20 - 4 . 
     In an alternate embodiment of the invention hinge element  30 - 144  may be disposed on any one of the four edges of the wall plate assembly  30 - 14 . (In this instance, the wall plate  30 - 14  may include a separate frame member that is coupled to the wiring device  10 . Depending on the hinge location, the antenna assembly  30 - 3  can rotates downwardly, side-to-side or upwardly. As before, the angle of inclination (θ) between the wall surface and antenna wall plate assembly  30  can be 0 to 20 degrees. In the embodiments with a lateral hinge, i.e., where the hinge is disposed on one side of the wall plate assembly  30 - 14 , it may be configured to have a closed or “stowed” position in which the angle of inclination (θ) from the wall surface to the assembly is between 0 to 180°. As before, the wall plate assembly  30 - 14  may be configured to hide or cover the electrical wiring device  10  in the stowed position. 
     In these embodiments the circuit assembly  20 - 1  is housed between the antenna housing body  20 - 2  and the antenna wall plate  30 - 3 . As before, the circuit assembly  20 - 1  includes a printed circuit board (PCB)  20 - 4 . The PCB  20 - 4  includes various control circuits (not visible in this view) disposed on the back side thereof. The front side includes a shielding structure  20 - 6  that accommodates a plurality of antenna coils  20 - 10 . The shielding structure  20 - 6  prevents a magnetic field from heating any metallic structures behind the assembly  100  (e.g., a metallic device box or an electronic component). In the example shown in this view, the antenna is comprised on three coils ( 20 - 10 - 1 ,  20 - 10 - 2 , and  20 - 10 - 3 ). As before, the PCB  20 - 4  also includes a plug receptacle  20 - 40  that is configured to accommodate the plug from the DC supply cord  40 . Specifically, the DC supply cord will provide a DC supply voltage (e.g., +5 DCV) for the antenna coil and the control circuitry. 
     Referring to  FIG. 6A , a front isometric view of an electrical wiring assembly in accordance with another embodiment of the invention is disclosed. In this embodiment, the electrical assembly  100  includes a wall plate housing assembly  300  that includes an assembly frame  300 - 2  that accommodates the electrical wiring device  10  and the antenna housing  300 - 3 . A device wall plate  30 - 140  and an antenna wall plate  300 - 4  couple to the assembly frame  300 - 2  while completing the enclosure. 
     The antenna wall plate  300 - 4  includes the cradle ledge  30 - 12  for the device under charge. As before, the antenna logo plate  30 - 6  is disposed on the antenna assembly wall plate portion  300 - 4  within a recessed portion ( 30 - 60 ). 
     Referring to  FIG. 6B , a rear isometric view of the electrical wiring assembly depicted in  FIG. 6A  is disclosed. As before, the electrical wiring device  10  extends through an opening  300 - 20  so that the wiring terminals are accessible for AC wiring. Note however, that the antenna housing  300 - 3  is configured to rotationally move within an antenna frame opening  300 - 22  between a flush position (i.e., flush with the frame) and an inclined position (i.e., a charging position). 
     Referring to  FIG. 6C , an exploded view of the electrical wiring assembly depicted in  FIG. 6A  is disclosed. In this embodiment, the wiring device  10  is mounted to the device box (not shown) via the frame  300 - 2 . The rear portion of the device  10  extends through the opening  300 - 20 . The front wall plate  30 - 140  includes an opening  300 - 20  that allows the user to access the front receptacles. The front wall plate  30 - 140  snaps into the frame  300 - 2  to complete the electrical wiring device enclosure. 
     The antenna housing  300 - 3  includes an antenna compartment  300 - 24  that contains the AC circuit assembly  20 - 1 . The front wall plate cover  300 - 4  snaps into the antenna compartment  300 - 24  so that the AC circuit assembly  20 - 1  is enclosed. The antenna housing  300 - 3  further includes a hinge  300 - 26  that can be inserted into either one of the hinge ferrules  300 - 28 . The hinge  300 - 26  is inserted into opposing hinge slots  300 - 23  formed in the upright posts  300 - 4  that form antenna housing opening  300 - 22 . 
     Referring to  FIG. 6D , a side elevation view of the electrical wiring assembly depicted in  FIG. 6A  is shown with a portable electronic device  1  in a charging position.  FIG. 6E  is the opposing side elevation view of the electrical wiring assembly depicted in  FIG. 6D  with the portable electronic device  1  in the charging position. 
     Referring to  FIGS. 7A-7B , detail sectional views illustrating electrical wiring assembly power interconnections in accordance with the invention are disclosed.  FIG. 7A , for example, shows the wall plate assembly  30  that includes an integral wall plate  30 - 1  having an electrical wiring device wall plate  30 - 2  and an antenna assembly wall plate  30 - 3 . As before, the low voltage power cord  40  is connected to the electrical wiring device  10 . From there, the cord  40  is routed under the electrical wiring device wall plate  30 - 2  and passes through an aperture in the wall separating the electrical wiring device  10  from the antenna assembly  20 . Once the cord  40  is through the aperture, it can be inserted into the antenna assembly  20 . 
       FIG. 7B  shows an arrangement for a wall plate housing assembly  300  such as the embodiment of  FIG. 6 , for example. In this type of housing arrangement, the electrical wiring device wall plate  30 - 2  and the antenna assembly wall plate  30 - 3  are snapped separately into the back plate  300 - 2 . As before, the low voltage power cord  40  is routed through an aperture in the wall separating the electrical wiring device  10  from the antenna assembly  20  and inserted into the antenna assembly  20 . 
     Referring to  FIG. 8 , a front isometric view of an electrical wiring assembly  100  in accordance with another embodiment of the invention is disclosed. This embodiment is very similar to the embodiment of  FIG. 1  except that the antenna assembly  20  is directly wired to an AC power supply. In this embodiment, the electrical wiring device  10  is an off the shelf wiring device that does not have to provide special cabling (such as a DC power cord) to the circuit assembly  20 - 1 . Instead, the wall plate includes an aperture (not visible in this view) in the side wall  30 - 4  that accommodates an AC power cord  50  terminated with an AC plug  50 - 1 . The AC plug  50 - 1  can be inserted into the outlet receptacle  10 . Because the antenna assembly  20  is directly wired to an AC power supply instead of with low voltage DC as in other embodiments of the invention, an AC/DC converter is included in the antenna assembly  20  to provide the circuit assembly  20 - 1  with a suitable source of power. (Some antenna coils require a lower voltage AC power source. Moreover, the circuitry  20 - 1  may require a DC voltage source. Thus, all of these requirements may be supported by a power supply assembly disposed within the antenna housing  300 - 3 ). 
     One application of the embodiment of  FIG. 8  is directed to a retrofit of an existing AC wiring device installation. Once the original or existing wall plate is removed, the wall plate assembly  30  is installed by coupling the electrical wiring device wall plate  30 - 2  over the existing wiring device  10 . Since the wiring device wall plate  30 - 2  and the antenna wall plate  30 - 3  are integrally formed, one need only insert the corded plug assembly  50  into the device  10  to complete the installation. As those skilled in the art will appreciate any of the electrical wiring assemblies  100  disclosed herein can be configured so that the antenna assembly  20  is directly wired to AC power supply. 
     Referring to  FIG. 9 , a rear isometric view of an electrical wiring assembly  100  in accordance with another embodiment of the invention is disclosed. To illustrate the concept that any of the electrical wiring assemblies  100  disclosed herein can be configured so that the antenna assembly  20  is directly wired to AC power supply, this embodiment is an adaptation of the embodiment of  FIGS. 4A-C . Moreover,  FIG. 9  is very similar to  FIG. 4B . For brevity&#39;s sake, the rear portion of the wall plate housing assembly  300 - 2  depicted in  FIG. 9  includes two alternative AC wiring termination schemes. The first AC wiring scheme includes the provision of AC wiring terminals  300 - 40  on the major rear surface of the housing  300 - 2  to which pigtails  300 - 42  are connected. The second AC wiring method include AC pigtails  300 - 42  extending from an aperture formed in the major rear surface of the housing  300 - 2 . Either way, pigtails  300 - 42  are connected to wiring terminals  10 - 14  or to wires in the outlet box. The pigtail wires, additional pigtail wires to terminals  10 - 14  and wires inside the outlet box, may be joined together using twist-on connectors. As before, because the antenna assembly  20  is directly wired to AC power supply, the antenna assembly  20  further includes an AC/AC converter, an AC/DC converter or some other suitable power supply that is configured to provide the circuit assembly  20 - 1  with suitable (AC and/or DC) power. This embodiment may require use of a double gang wall box if the power supply circuitry or wiring terminals  300 - 40 , pigtail wires or some other feature of antenna assembly  20  prevents housing  300 - 2  from being installed flush with the wall surface. 
     In reference to the various embodiments described herein, those skilled in the art will appreciate that embodiments of this invention can include a suitable power supply disposed in either the electrical wiring device, the antenna assembly or both, depending on the functionality of the assembly  100 . For example, the power supply may be configured to convert high voltage AC (e.g., 120 VAC) to low voltage AC or convert high voltage AC to DC in order to provide suitable power to the antenna assembly. In some embodiments shown herein, the power supply circuitry may be dual-purpose, i.e., it may also be configured to provide a suitable power source to user accessible low voltage ports (e.g., USB ports), analog circuits, and/or digital circuitry. 
     Referring to  FIG. 10 , another rear isometric view of an electrical wiring assembly is disclosed.  FIG. 10  is also very similar to  FIG. 4B . In this embodiment, an AC receptacle is formed in the rear of the major rear surface of the housing  300 - 2 . In this method, one need only insert a corded AC power plug into receptacle  300 - 44  to provide AC power to the antenna assembly  20 . Again, because the antenna assembly  20  is directly wired to AC power supply, the antenna assembly  20  further includes an AC/AC converter, an AC/DC converter or some other suitable power supply that is configured to provide the circuit assembly  20 - 1  with suitable power. 
     As embodied herein and depicted in  FIG. 11A , a front isometric view of an electrical charging wiring device  10  in accordance with an embodiment of the invention is disclosed. This embodiment may be employed in a form factor suitable for a modular wiring device system. Reference is made to U.S. patent application Ser. No. 13/680,675, which is incorporated herein by reference as though fully set forth in its entirety, for a more detailed explanation of the modular wiring device system. The wiring device depicted in  FIGS. 11A-C  can be configured as a two or three-module device of the type shown in the &#39;675 application and can be disposed in any of the modular frames (See, e.g.,  FIGS. 1 and 9-12 ). 
     This embodiment is similar to the embodiment of  FIGS. 6A-E  in that the antenna housing  30 - 3  is configured to rotationally move within a frame opening  30 - 20  between a flush position (i.e., flush with the frame  30 - 34 ) and an inclined position (i.e., a charging position). The frame  30 - 34  is mounted, in this embodiment, to the front of the antenna housing  30 - 3 , which is disposed within the electrical wiring device housing  10 - 2 .  FIG. 11B  is a rear isometric view of the electrical wiring device  10  depicted in  FIG. 11A . In this view, the rear major surface of the housing  10 - 2  includes AC wiring terminal openings  10 - 14 . Those skilled in the art, however, will appreciate that conventional wiring terminals  10 - 14  (see, e.g.,  FIG. 1B ) may be employed instead. 
     Referring to  FIG. 11C , an exploded view of the electrical wiring device depicted in  FIG. 11A  is disclosed. In this view, the antenna housing may be removably inserted into the opening  10 - 16 - 1 . Specifically, the AC/DC conversion assembly  10 - 16  includes DC power terminals  10 - 160  that are configured as spring loaded push terminals. That is, once the DC terminals (not visible in this view) formed in the rear of the antenna housing are mated with the DC power jacks  10 - 160 , one need only push the front face plate  30 - 32  and the antenna assembly  30  will be ejected from the opening  10 - 16 - 1 . 
     One benefit of this approach relates to the ability of the user to employ different low power wiring device applications as needed. For example, a user may desire to insert an emergency flashlight insert into the opening  10 - 16 - 1  after the portable electronic device has been charged. This allows the wiring device to fulfil many different functions. Reference is made to U.S. patent application Ser. No. 13/835,076, which is incorporated herein by reference as though fully set forth in its entirety, for a more detailed explanation of a removable night light. Another benefit of this embodiment relates to the ability of the user to replace, interchange, or upgrade the antenna assembly with a different antenna assembly as needs change and technology evolves. Note that the high voltage wiring remains installed and undisturbed during the antenna replacement process. Thus, the antenna assembly is “modular” in that it is easy to replace. 
     Referring to  FIG. 11D , an exploded view of an AC module portion  10 - 16  of the electrical wiring device depicted in  FIG. 11A  is disclosed. The AC module portion  10 - 16  includes push release mechanisms  10 - 166  that alternately hold the antenna assembly  30  within the housing  10 - 2  and release the antenna assembly  30  when the user decides to employ another application module. An AC power printed circuit board assembly (AC PCB)  10 - 161  is disposed in the rear part of the housing  10 - 2 . The AC PCB  10 - 161  includes power supply jacks  10 - 163  that are configured to be inserted into the jacks  10 - 160  formed in the low power assembly tray  110 - 164 . AC PCB  10 - 161  also includes hardware for AC wiring terminals  10 - 165 ; the hardware  10 - 165  is accessible via the terminal openings  10 - 14  (See  FIG. 11B ). Alternatively, the terminal hardware may be implemented using conventional AC wiring terminals. The tray member  10 - 164  also accommodates slide stop elements  10 - 162  which are disposed either side of the tray  10 - 164  as shown. The slide stops  10 - 162  snap into the housing  10 - 2  and serve to restrict the travel of the tray  10 - 164  between two positions governed by the release mechanism  10 - 166 . The slide stops  10 - 162  also provide a snug fit for the antenna assembly  30  while allowing it to be completely removed from the tray or reinserted into the tray. The slide stops  10 - 162 , on the other hand, are not removable from either the tray or the housing  10 - 2 ; when the tray  10 - 164  and slide stops  10 - 162  are installed, no AC wiring or parts associated with them or AC PCB  10 - 161  are accessible to the consumer even when the antenna assembly  30  is removed from tray  10 - 164 . 
     As before, the power supply circuitry disposed within housing  10 - 2  may be configured to convert high voltage AC (e.g., 120 VAC) to low voltage AC or convert high voltage AC to DC in order to provide suitable power to the antenna assembly or any a replacement assembly. 
     Referring to  FIG. 12A , a front view of an electrical wiring device in accordance with another embodiment of the invention is disclosed. While this embodiment may be employed in a conventional wiring device form factor for a single gang wall box (See, e.g.,  FIGS. 8-10 ), it is functionally identical to the embodiment of  FIGS. 11A-D . Since like reference numbers are assigned to like parts, and the embodiment of  FIGS. 12A-B  is functionally identical to the embodiment of  FIGS. 11A-D , further disclosure is unnecessary. Thus, as shown in  FIG. 12B —which is an exploded view of the electrical wiring device depicted in  FIG. 12A —the antenna assembly  30  can be inserted and removed from the wiring device housing  10 - 2  in the manner described above. 
     Referring to  FIGS. 13A-13B , a front view and an exploded view, respectively, of an electrical charger wiring device  200  in accordance with the invention are disclosed.  FIG. 13A  is a front view of the electrical charger wiring device  200 . Like a previous embodiment, this embodiment is in a form factor suitable for a modular wiring device system. Reference is made to U.S. patent application Ser. No. 13/680,675, which is incorporated herein by reference as though fully set forth in its entirety, for a more detailed explanation of the modular wiring device system. The wiring device  200  depicted in  FIGS. 13A-B  can be configured as a two or three-module device of the type shown in the &#39;675 application. While a cradle (e.g.,  30 - 12 ) for the device-under-charge  1  is not shown in this view, those skilled in the art will appreciate that a cradle may be part of the wiring device  200 , or part of the wall plate assembly ( 30 ,  300  or  3000 ) as described herein. 
     In the exploded view shown in  FIG. 13B , the circuitry  20 - 1  is disposed between a front cover  202  and a back body  204 . The electrical terminals  20 - 12  are not shown in this view for clarity&#39;s sake. Obviously, AC power must be routed from the AC distribution system to the device  200 . In addition, the antenna circuit  20 - 1  is configured as a single antenna  20 - 10  device, but those skilled in the art will appreciate that the device  200  can be configured to include an antenna circuit  20 - 1  with two or three antennas. As before, the underside of the printed circuit board  20 - 4  may include analog and/or digital control circuitry, a power supply circuit and other suitable circuitry. 
     Referring to  FIGS. 14A-14B , a front view and an exploded view, respectively, of an electrical charger wiring device  210  in accordance with another embodiment of the invention is disclosed. This embodiment is in a conventional electrical wiring device form factor.  FIG. 14A  is a front view of the electrical charger wiring device  210  and includes conventional mounting ears  10 - 14  disposed between the front cover  212  and the back body  214 . As before, while a cradle for the device-under-charge  1  is not shown in this view, those skilled in the art will appreciate that a cradle (e.g.,  30 - 12 ) may be part of the wiring device  210 , or part of the wall plate assembly ( 30 ,  300  or  3000 ) as described herein. 
       FIG. 14B  is an exploded view of the device  210  and shows the circuitry  20 - 1  disposed between a front cover  212  and a back body  214 . The electrical terminals  20 - 12  are not shown in this view for clarity&#39;s sake. Obviously, AC power must be routed from the AC distribution system to the device  210 . In this view, the antenna circuit  20 - 1  is configured as a tri-antenna  20 - 10  device, but those skilled in the art will appreciate that the device  200  can be configured to include an antenna circuit  20 - 1  with one or two antenna coils. As before, the underside of the printed circuit board  20 - 4  may include analog and/or digital control circuitry, a power supply circuit and other suitable circuitry. The mounting strap  10 - 14  is depicted herein in dashed lines because it may be configured in any number of ways depending on the device  210  realization. In this view, it is shown in a wraparound strap form factor. In another embodiment, the strap  10 - 14  may be disposed over top the circuitry  20 - 1  and, thus, be configured in a substantially linear through strap form factor. 
     As embodied herein and depicted in  FIG. 15A , a front view of a wall box assembly  3000  in accordance with another embodiment of the invention is disclosed. This embodiment may be employed in a new construction application. The wall box  3000  includes a framing portion that has upright frame posts  3000 - 2  connected to horizontal framing members  3000 - 6 . An interior compartment  3000 - 1  is formed by wall, floor and ceiling surfaces  3000 - 4 . The wall surfaces  3000 - 4  include an opening  3000 - 8  that is dedicated to an AC electrical wiring device and another opening  3000 - 10  that is dedicated to the antenna assembly  30 . Note that the size of the antenna device opening  3000 - 10  may vary depending on the size of the antenna assembly  30  selected by the user. The size of the opening  3000 - 1  and the antenna assembly  30  may depend on the largest type of portable electronic device that the user foresees charging. 
     Referring to  FIG. 15B , a top view of the wall box assembly  3000  depicted in  FIG. 15A  is disclosed. In this view, the electrical wiring device  10  is installed in the opening  3000 - 8  and the antenna assembly  30  is installed in the opening  3000 - 10 . In one embodiment, the wiring device  10  provides the antenna assembly  30  with DC power (see embodiments of  FIGS. 1-6 ). In another embodiment, AC power wiring  50  is coupled to the antenna assembly  30  (See, e.g.,  FIGS. 8-10 ). The dashed line indicates the footprint of the inclined antenna wall plate  30 - 3  and the cradle ledge  30 - 12 . The interior compartment  3000 - 1  provides a region recessed within the wall surface that can accommodates at least one portable electronic device for wireless charging. Thus, the user places the device under charge (DUC)  1  into the interior compartment  3000 - 1  so that a passerby or pet cannot inadvertently knock the DUC  1  off the cradle. 
     Those skilled in the art will appreciate that the wiring device embodiments shown in  FIGS. 13A-14B  and described in the related text may be employed in the wall box assembly embodiments depicted in  FIGS. 15A-B  as stand-alone charger electrical wiring devices. 
     As embodied herein and depicted in  FIG. 16A , a front view of a wall box assembly  3000  in accordance with another embodiment of the invention is disclosed. In this view, a modular wall box housing assembly includes a frame portion  3000 - 6  that is substantially flush with the drywall when the assembly  3000  is installed. The frame  3000 - 6  can include a top aesthetic flange cover  3000 - 60  and a bottom aesthetic flange cover  3000 - 62 . The aesthetic flanges ( 3000 - 60 ,  62 ) cover mounting flange portions of the frame  3000 - 6  so that the mounting screws are hidden from view. Thus, the flange covers ( 3000 - 60 ,  62 ) provide an aesthetically pleasing finish that consumers appreciate. Reference is made to co-pending U.S. patent application Ser. No. 11/247,896, filed on Oct. 11, 2005, which is incorporated herein by reference as though fully set forth in its entirety, for a more detailed explanation of designer flange covers ( 3000 - 60 ,  62 ) in accordance with an alternate embodiment of the present invention. In this view, the assembly  3000  is a three gang assembly that includes a recessed region  3000 - 1  that has three planar device mounting surfaces  3000 - 4 , a planar roof portion  3000 - 3 , and a planar floor surface  3000 - 5 . Thus, in this embodiment, the assembly  3000  is a three-gang assembly that can accommodate any combination of AC wiring devices  10  or antenna assemblies  30 . Thus, this assembly  3000  can include more than one antenna assembly  30 . 
     Referring to  FIG. 16B , a top view of the wall box assembly depicted in  FIG. 16A  is shown with an electrical wiring device  10  installed at each end and an antenna assembly  30  disposed in the middle.  FIG. 16C  is a front elevation view of the wall box assembly depicted in  FIG. 16A  with the portable electronic device  1  in the charging position. 
     Those skilled in the art will appreciate that the wiring device embodiments shown in  FIGS. 13A-14B  and described in the related text may be employed in the wall box assembly embodiments depicted in  FIGS. 16A-C  as stand-alone charger electrical wiring devices. 
     Referring to  FIG. 17A , a front isometric view of a wall plate assembly  30  in accordance with another embodiment of the invention is disclosed. This embodiment is similar to the embodiment of  FIG. 1  except that the antenna assembly  20  is directly wired to the AC power supply. In this embodiment, the electrical wiring device  10  is an off-the-shelf wiring device in that it does not include an AC/DC converter. Thus, the DC power cord between the wiring device  10  and the antenna assembly  30  is not required. Instead, the electrical wiring device wall plate portion  30 - 2  includes AC power connection fingers  60  that are configured to contact the electrical wiring device terminals  10 - 14  when the wall plate  30  is installed.  FIG. 17B  is a front elevation view of the wall plate assembly depicted in  FIG. 17A . 
     Because the antenna assembly  20  is directly wired to AC power supply, the antenna assembly  20  further includes a suitable power supply that provides the circuit assembly  20 - 1  with suitable power. 
     Like  FIG. 8 , one application of the embodiment of  FIGS. 17A-B  is a retrofit of an existing AC wiring device installation. The user need only remove the existing wall plate and install the wall plate assembly  30 . To be specific, once the original or existing wall plate is removed, the electrical wiring device wall plate  30 - 2  is installed over the existing wiring device  10  so that the fingers  60  make contact with the wiring terminals  10 - 14 . Since the wiring device wall plate  30 - 2  and the antenna wall plate  30 - 3  are integrally formed, the antenna assembly  30  is automatically installed once the wall plate  30 - 2  is installed. 
     As embodied herein, and depicted in  FIG. 18A , a front isometric view of an electrical wiring assembly  100  in accordance with an embodiment of the invention is disclosed. Like the embodiment of  FIGS. 11A-11D and 13A -B, this embodiment may be employed in a form factor suitable for a modular wiring device system. Thus, reference is made to U.S. patent application Ser. No. 13/680,675, which is incorporated herein by reference as though fully set forth in its entirety, for a more detailed explanation of the modular wiring device system. The components depicted in  FIGS. 15A-15B  are similar to the components depicted in  FIGS. 1A-1F , but it should be appreciated that any of the embodiments depicted herein may be employed using the modular system disclosed in the &#39;675 application referenced above. 
     The electrical assembly  100  includes a wall plate assembly  30  that is configured to accommodate an electrical wiring device  10  and an antenna assembly  20  (not shown in this view). The wall plate assembly  30  includes an integrally formed aesthetic wall plate  30 - 1  that is configured to couple to the frame member  12  (not shown in this view). The aesthetic wall plate  30 - 1  includes an electrical wiring device wall plate portion  30 - 2  and an antenna assembly wall plate portion  30 - 3 . The integrally formed wall plate also includes a side wall  30 - 4  having a substantially triangular shape; i.e., it includes a first major side that is configured to abut a wall surface and a second major side that extends at an angle so that the antenna wall plate  30 - 3  is inclined. 
     The wall plate assembly  30  also includes a device cradle  30 - 10  that includes a cradle pad  30 - 100 . The cradle pad  30 - 100  is comprised of a material that has a relatively high coefficient of friction. An antenna logo plate  30 - 6  is disposed on the antenna assembly wall plate portion  30 - 3  within a recessed portion ( 30 - 60 ). The plate  30 - 6  is also comprised of a material that has a relatively high coefficient of friction. Thus, a portable electronic device under charge that is resting in the cradle  30 - 10  and propped against the antenna wall plate  30 - 3  will remain in place (due to the frictional forces exceeding gravitational forces). 
     The electrical wiring device wall plate portion  30 - 2  has a three module sized opening  30 - 20  formed therein to accommodate a two-module sized electrical wiring device  10  and a one module sized USB port device  11 . According to the present invention, an electrical wiring device  10  may be configured as an outlet receptacle or as a protective device, such as a ground fault circuit interrupter (GFCI), an arc fault circuit interrupter (AFCI), a transient voltage surge suppressor (TVSS), or a surge protective device (SPD). Other electrical wiring device examples include dimmers, fan speed controls, night lights, low voltage ports, or USB ports. Finally, each of these wiring device modules may be found in mix-and-match combinations with other kinds of these wiring devices. For example, a GFCI/AFCI combination device may be included within a single housing. 
     Referring to  FIG. 18B , a rear isometric view of the electrical wiring assembly  100  depicted in  FIG. 18A  is disclosed. The electrical wiring device  10  and the USB port device  11  are shown extending through the frame member  12 . In this embodiment, the USB port device  11  includes an AC/DC converter circuit (not shown). A DC power cord  40  is coupled to the AC/DC converter via a terminal in the side of the electrical wiring device  10 . The opposite end of the cord  40  includes a plug that is configured to be inserted into the antenna plug opening  20 - 20  disposed at the top end of the antenna back body  20 - 2 . Of course, the antenna back body  20 - 2  is configured to form a rear volume together with side wall  30 - 4 . Moreover, the antenna back body  20 - 2  is configured to be connected to the inside of the antenna wall plate portion  30 - 3  to complete the antenna assembly  20  enclosure. 
     Note that the portable device cradle  30 - 10  is coupled to a ratchet member  30 - 8  on each side thereof. The ratchet members  30 - 8  allow the cradle  30 - 10 —and hence the portable device  1 —to be adjusted up or down so that the antenna coil in the antenna housing  20 - 2  substantially aligns with the antenna coil disposed in the portable device  1 . Specifically, each ratchet  30 - 8  is disposed within a recess  20 - 22  formed in a side portion of the antenna back body  20 - 2 . Each ratchet  30 - 8  also includes a catch element  30 - 80  disposed on the ratchet  30 - 8  end opposite the cradle  30 - 10 . The catch member  30 - 80  is configured to move between the ratchet steps  20 - 24  that are formed in the ratchet recess regions  20 - 22 . 
     As described in the &#39;675 application, the frame member  12  is configured to “complete the electrical enclosure” when one or more modular electrical devices and/or modular alignment connectors are properly installed within the frame opening such that the device wall box interior is substantially inaccessible. Stated differently, instead of using a conventional wall plate to complete the enclosure, the frame member  12  is used to prevent individuals from being shocked or electrocuted by concealing all electrical wiring under the frame  12  within the device wall box interior. Reference is again made to U.S. patent application Ser. No. 13/680,675, which is incorporated herein by reference as though fully set forth in its entirety, for a more detailed explanation of the frame member  12  and the modular connectors (not shown herein). 
     Referring to  FIG. 18C , a front isometric view of the electrical wiring assembly  100  depicted in  FIG. 18A  is disclosed with a portable electronic device in a charging position. This view is identical to  FIG. 18A  with the exception that a portable device  1  (e.g., a cell phone) is shown resting on the cradle  30 - 10 . 
     Referring to  FIG. 18D , a side elevation view of the electrical wiring assembly  100  depicted in  FIG. 18A  is disclosed. In this view, the portable electronic device is shown in the charging position. As before, the side wall  30 - 4  has a substantially triangular shape; thus, the antenna wall plate  30 - 3  is inclined at an angle θ relative to the substantially vertical wall surface. The angle θ may be within a range substantially between 0° and 20°. Referring to  FIG. 18E , another side elevation view of the electrical wiring assembly  100  depicted in  FIG. 18A  is disclosed. Again, the portable electronic device is shown in the charging position. 
     As embodied herein and depicted in  FIG. 18F , an exploded view of the electrical wiring assembly  100  depicted in  FIG. 18A  is shown. This view shows with more clarity the aesthetic wall plate  30 - 1  that couples to frame  12 ; again, the aesthetic cover  30 - 1  includes an electrical wiring device wall plate portion  30 - 2  that is integrally formed with the antenna assembly wall plate portion  30 - 3 . The wall plate portion  30 - 3  includes a recessed region  30 - 60  that is configured to accommodate the antenna bearing plate  30 - 6 . The antenna housing  20 - 2  includes a circuit assembly  20 - 1  that is disposed within the space formed by the antenna back body member  20 - 2  and the interior wall of plate  30 - 3 . The antenna housing  20 - 2  is further protected by the side wall  30 - 4 . 
     As before, the circuit assembly  20 - 1  includes a printed circuit board (PCB)  20 - 4 . The PCB  20 - 4  includes various control circuits (not visible in this view) disposed on the back side thereof. The front side includes a shielding structure  20 - 6  that accommodates a single antenna coil  20 - 10 . The shielding structure  20 - 6  prevents a magnetic field from heating any metallic structures behind the assembly  100  (e.g., a metallic device box). The PCB  20 - 4  also includes a plug receptacle  20 - 40  that is configured to accommodate the plug from the DC supply cord  40 . Specifically, the DC supply cord will provide a DC supply voltage (e.g., +5 DCV) for the antenna coil and the control circuitry. 
     Referring to  FIGS. 19A-19D , various views of an electrical wiring assembly featuring an electric switch wiring device  11  in accordance with the invention are disclosed.  FIG. 19A  is a front isometric view of the electrical wiring assembly  100  and features a wall plate housing assembly  300  that is configured to accommodate an electrical switch device  11  and an antenna assembly  20  (not shown in this view). The wall plate assembly  300  includes an integrally formed wall plate  300 - 4  that includes an electrical wiring device wall plate portion  300 - 4 - 1  and an antenna assembly wall plate portion  300 - 4 - 2 .

     The circuit assembly  20 - 1  includes a printed circuit board (PCB)  20 - 4 . The PCB  20 - 4  includes various control circuits (not visible in this view) disposed on the back side thereof. The front side includes a shielding structure  20 - 6  that accommodates a single antenna coil  20 - 10 . The shielding structure  20 - 6  prevents a magnetic field from heating any metallic structures behind the assembly  100  (e.g., a metallic device box or electronic components). The PCB  20 - 4  also includes an AC interconnection  20 - 40  that is configured to connect the AC power wiring  50  to the PCB  20 - 4 . The AC wiring  50  is, of course, connected to the wiring terminals  300 - 40  shown in  FIG. 19B . 
     Referring to  FIGS. 20A-20B , detail views illustrating a method for fastening an antenna wall plate ( 30 ,  300  or  3000 ) to a mounting surface is disclosed.  FIG. 20A  is an isometric view of the wall plate  300  from substantially underneath the assembly  100 . In this view, the wall plate housing  300 - 4  is shown to include fastener apertures  300 - 5 ; each aperture  300 - 5  accommodates a suitable fastener  2 .  FIG. 20B  is a sectional view of one of the fastener apertures  300 - 5  depicted in  FIG. 20A . Thus, each fastener aperture  300 - 5  is substantially slanted so that the fastener screw  2  can attach the antenna wall plate portion  300 - 4 - 2  to the wall surface. This embodiment may be employed in conjunction with any of the wall plate embodiments ( 30 ,  300  or  3000 ) described herein. 
     Referring to  FIG. 21 , a detail view illustrating another method for fastening an antenna wall plate ( 30 ,  300  or  3000 ) to a mounting surface is disclosed. In this embodiment, a rear wall mount structure  3  is attached to the wall surface after the wiring device ( 10 ,  11 ) is mounted to the wall box and before the wall plate assembly  300  is installed. The wall plate  300  includes a wall mount catch  300 - 7  that is configured to engage the rear wall mount structure  3  so that the antenna assembly wall plate portion  300 - 4 - 2  is affixed to the wall. Subsequently, the screws for the wiring device portion  300 - 4 - 1  can be threaded into the mounting ears  10 - 14  or wall box to complete the installation. This embodiment may be employed in conjunction with any of the wall plate embodiments ( 30 ,  300  or  3000 ) described herein. 
     Referring to  FIG. 22 , a detail view illustrating another method for fastening an antenna wall plate to a mounting surface is disclosed. This embodiment may be employed with a wall plate assembly ( 30 ,  300 , or  3000 ) that features a rear frame element  30 - 2 , for example. Before the electrical wiring device ( 10 / 11 ) is mounted to the device box via the frame  30 - 2 , an adhesive (PSA) material  4  is applied to the wall at a location under the frame  30 - 2  that supports the antenna assembly wall plate portion  30 - 4 . Once the frame  30 - 2  is affixed to the wall by the PSA  4 , the electrical device  10 / 11  may be coupled to the device box via the frame  30 - 2 . After this, the electrical wall plate  30 - 140  and the antenna wall plate  30 - 4  may be snapped into the frame  30 - 2  to complete the installation. 
     Referring to  FIGS. 23A-23B , detail views illustrating a cradle assembly  30 - 120  for accommodating portable electronic devices of varying sizes are disclosed. In this embodiment, the cradle assembly  30 - 120  includes top and bottom cradles  30 - 12  that are coupled to a movable rack portion  30 - 122 . The movable rack portion  30 - 122  is, in turn, coupled to pinion gear  30 - 124 . The pinion gear  30 - 124  is coupled to a spring element  30 - 126  that is configured to drive the rack  30 - 122  into a minimum sized opening. Thus, when a user places the portable electronic device  1  between the cradles  30 - 12 , the top and bottom cradles  30 - 12  will separate until the device  1  is therebetween. Moreover, the spring force urges the cradles  30 - 12  together so that the device is kept firmly in place. 
     Note that the wall plate assembly  30  is shown to include an inclined surface  30 - 4 ; however, this embodiment fully supports an antenna wall plate surface  30 - 4  that is substantially parallel to the wall surface (i.e., substantially no inclination). 
     Referring to  FIGS. 24A-24D , various isometric views of an electrical charger wiring device in accordance with the invention are disclosed.  FIG. 24A  is a front view of the electrical charger wiring device  200 . In this view, the front cover  202  is substantially flush with the wall plate  30 . Like a previous embodiment, this embodiment is in a form factor suitable for a modular wiring device system. Reference is made to U.S. patent application Ser. No. 13/680,675, which is incorporated herein by reference as though fully set forth in its entirety, for a more detailed explanation of the modular wiring device system.

       FIG. 26A  shows the front cover  202  flush with the cover plate  30 . As illustrated by  FIG. 26B , a rear housing  204  (not shown in this view) includes push release mechanisms that alternately hold a front enclosure  202  (and the antenna assembly  20 ) within the rear housing  204  and release the front enclosure  202  in response to being depressed by a user. 
     In  FIG. 26B , a side wall  202 - 2  of the front enclosure  202  has a substantially rectangular form factor that accommodates an electrical receptacle  10 - 6 . The opposing side wall  202 - 3  includes several USB ports  10 - 8 . Thus, the rectangular shaped wiring device  202  includes a 120 VAC to low voltage power supply of the type described herein. In  FIG. 26C , the opposing side wall  202 - 3  may include a charger switch  202 - 4  that may be used to signal the controller to begin a charging routine (not shown in this view). In another embodiment, the cradle surface  202 - 12  may include a capacitive touch plate that signals the controller to begin charging.  FIG. 26D  shows the portable device in charging position. 
     Referring to  FIGS. 27A-27B , various isometric views of an electrical charger wiring device  200  in accordance with the invention are disclosed. Like a previous embodiment, this embodiment is in a form factor suitable for a modular wiring device system. Reference is made to U.S. patent application Ser. No. 13/680,675, which is incorporated herein by reference as though fully set forth in its entirety, for a more detailed explanation of the modular wiring device system. 
     In  FIG. 27A , the front cover  202  is flush with the cover plate  30 . As illustrated by  FIG. 27B , a rear housing  204  (not shown in this view) includes push release mechanisms that alternately hold the cradle assembly  202 - 12  within the rear housing  204  and release the cradle assembly  202 - 12  in response to being depressed by a user. In this embodiment, the antenna logo plate—which locates the antenna coil—is disposed on the cradle. Thus, the antenna coil  20 - 10  is disposed in the retractable cradle  202 - 12 . In an alternate embodiment, the antenna coil  20 - 10  may be disposed behind the wall plate  30 . 
     Referring to  FIGS. 28A-28B , isometric views of an electrical wiring assembly  100  in accordance with another embodiment of the invention are disclosed. This embodiment is similar to the embodiments described in conjunction with  FIGS. 1-6 . Thus, in reference to the embodiment of  FIG. 4 , for example, the electrical assembly  100  may include a wall plate housing assembly  300  that includes a back body sub-plate  300 - 2  (not shown) coupled to a single wall plate cover  300 - 4  to form the wall plate housing assembly  300 . The electrical wiring device  10  and the antenna assembly  20  (not shown in this view) are substantially disposed within the housing  300 . Note that the rear portion of the electrical wiring device is open at the rear to allow for access to the AC wiring terminals  10 - 14  (not shown). This embodiment differs from previous embodiments in that the wall plate cover  300 - 4  is flush relative to the mounting (wall) surface. In this embodiment, the wall plate cover  300 - 4  includes a device cradle door  300 - 12  that is flush in  FIG. 28A  and open in  FIG. 28B . As before, the antenna logo plate  300 - 6  is disposed on the wall plate cover  300 - 4  to identify the position of the antenna assembly  20  within the housing  300 . 
     Referring to  FIGS. 29A-29B , isometric views of an electrical wiring assembly  100  in accordance with another embodiment of the invention are disclosed. This embodiment is similar to the one shown in  FIGS. 5A-5E . Similarly, the wall plate assembly  30  includes a wall plate  30 - 14  that is coupled to that antenna back plate  20 - 2  by a hinge element  30 - 144 . The antenna assembly  20  is disposed between the antenna back plate  20 - 2  and the antenna wall plate  30 - 3 . In  FIG. 29A , the antenna wall plate assembly  30  is shown in the stowed position substantially flush to the wall surface. In  FIG. 29B , the antenna wall plate assembly  30  is rotated outwardly and inclined at an inclination angle θ relative to the wall surface. 
     Referring to  FIG. 30 , an isometric view of an electrical wiring assembly in accordance with another embodiment of the invention is disclosed. This embodiment is similar to the one depicted in  FIGS. 29A-B , with the exception that the charger portion  30  is disposed above the wiring device  10  and at a fixed angle relative to the mounting surface. Moreover, since the antenna wall plate cover  30 - 3  is facing the wall, the antenna rear compartment  20 - 2  faces outwardly. Since the same reference numbers are used to refer to the same or like parts, no further description is deemed necessary. 
     Referring to  FIG. 31 , an isometric view of an electrical wiring assembly in accordance with another embodiment of the invention is disclosed. This embodiment is similar to the one depicted in  FIGS. 4A-4C  because it includes an integrally formed wall plate  30  that has substantially triangular side walls  30 - 4  that extend at an angle so that the antenna wall plate portion  30 - 3  is inclined. This embodiment features a lower inclined wall  30 - 2  that is configured to accommodate an outlet receptacle  10 - 6  and two USB ports  10 - 8 . Since the same reference numbers are used to refer to the same or like parts, no further description is deemed necessary. 
     Referring to  FIGS. 32A-32B , isometric views of an electrical wiring assembly in accordance with another embodiment of the invention are disclosed. This embodiment is similar to the one depicted in  FIGS. 4A-4C and 31  because it includes an integrally formed wall plate  30  that has substantially triangular side walls  30 - 4  that extend at an angle so that the antenna wall plate portion  30 - 3  is inclined. One side wall  30 - 4  includes an outlet receptacle  10 - 6 . The opposite side wall  30 - 5  includes two USB ports  10 - 8 . Since the same reference numbers are used to refer to the same or like parts, no further description is deemed necessary. 
     Referring to  FIG. 33  A, a front isometric view of an electrical wiring assembly in accordance with another embodiment of the invention is disclosed. In this embodiment, electrical assembly  100  includes a wall plate housing assembly  300 . The wall plate housing assembly  300  includes a single wall plate cover  300 - 4  coupled to a rear sub-plate  300 - 2  and an antenna back body  20 - 2  to form the wall plate housing assembly  300 . The electrical wiring device  10  and the antenna assembly  20  (not shown in this view) are substantially disposed within the housing  300 . Note that the rear portion of the electrical wiring device is open at the rear to allow for access to the AC wiring terminals  10 - 14 . The wall plate cover  300 - 4  has an opening  300 - 20  formed therein to accommodate the electrical wiring device  10 , and a recessed portion  300 - 60  configured to retain the antenna logo plate  300 - 6 . As described herein, wiring device  10  includes a USB port  10 - 8  for charging a portable device by way of a cord terminated with a USB plug when inserted in port  10 - 8 . The USB port  10 - 8  is powered by an AC/DC converter circuit inside electrical wiring device  10  (not shown). Reference is made to U.S. Pat. No. 8,758,031 which is incorporated herein by reference in its entirety for all that it teaches including a USB wiring device and all of its related circuitry and mechanical aspects. 
     The antenna logo plate  300 - 6  is disposed on the wall plate cover  300 - 4  within a recessed portion ( 30 - 60 ) for identifying the position of the antenna assembly  20  within the housing  300 . The plate  300 - 6  is comprised of a material that has a relatively high coefficient of friction for the reasons provided above. As described below, the antenna housing includes two primary coils ( 20 - 10 - 1 ,  20 - 10 - 2 ) that are configured to provide a more robust magnetic field, thus the need for an adjustable cradle is eliminated. 
     The wall plate cover  300 - 4  also includes a portable device cradle  70 . The cradle  70  may include a cradle gripper  70 - 1  that is spring biased or otherwise configured such that cradle  70  holds the portable electronic device against the antenna logo plate  300 - 6 . The cradle  70  is mounted to a bottom portion  70 - 2  of the front cover  300 - 4 . 
     Referring to  FIG. 33B , a rear isometric view of the electrical wiring assembly  100  depicted in  FIG. 33A  is disclosed. The electrical wiring device  10  extends through the opening  300 - 20 . As before, the electrical wiring device  10  is mounted to the device box after the AC wiring is connected to the wiring terminals  10 - 14  and then the wall plate cover  300 - 4  is attached. 
     Referring to  FIG. 33C , a front isometric view of the electrical wiring assembly depicted in  FIG. 33A  is disclosed with a portable electronic device in a charging position. This view is identical to  FIG. 33A  with the exception that a portable device  1  (e.g., a cell phone) is shown resting within cradle  70 . The portable electronic device so held is designed to be charged via wireless transmission, a cord whose plug is configured to plug into USB port  10 - 8 , or a cord connected to a battery pack and plug arrangement that derives power from one of the outlet receptacles  10 - 6 . 
     Referring to  FIG. 33D , a side elevation view of the electrical wiring assembly depicted in  FIG. 33A  is disclosed. In this view, a portable electronic device is shown in the charging position. As noted above, the cradle gripper  70 - 1  is spring biased such that the user can pull gripper  70 - 1  away from the antenna logo plate  300 - 6 , insert the portable electronic device between the gripper  70 - 1  and the plate  300 - 6  and release cradle gripper  70 - 1  to secure the device in position against the plate  300 - 6 . 
     Referring to  FIG. 33E , an exploded view of the electrical wiring assembly depicted in  FIG. 33A  is disclosed. The wall plate housing  300  is shown to include an electrical wiring device portion disposed directly within a rear sub-plate  300 - 2 . The electrical wiring device portion is shown to include the device opening  300 - 20 . The front wall plate cover  300 - 4  is disposed over the sub-plate frame  300 - 2  and the antenna back body  20 - 2  to complete the enclosure. Like previous embodiments, the front cover  300 - 4  includes a recessed region  300 - 60  that is configured to accommodate the antenna logo plate  300 - 6 . 
     As shown, the cradle gripper  70 - 1  may be spring-biased with the cradle spring  70 - 3 . Spring  70 - 3  may fit over a dowel  70 - 4 , which, in turn, may insert through openings  70 - 5  in the gripper  70 - 1  and fit into a slotted recess formed into mounting  70 - 2 , so as to secure the spring  70 - 3  and gripper  70 - 1  to mounting and form a spring-biased pivot by which gripper  70 - 1  may be pulled away from antenna logo plate  300 - 6 . Again, because gripper  70 - 1  is biased by spring  70 - 3 , when gripper  70 - 1  is released, it will return to antenna logo plate  300 - 6 , or will secure a portable device that is positioned between gripper  70 - 1  and antenna logo plate  300 - 6 . Cradle  70  may further comprise a front portion  70 - 6  that abuts the lower edge of the gripper  70 - 1 , and is curved so as to contact front wall plate cover  300 - 4  when the gripper  70 - 1  is pulled away from antenna logo plate  300 - 6 , to limit the distance the gripper  70 - 1  may pull away from the antenna logo plate  300 - 6 . 
     The antenna housing  20 - 2  includes a circuit assembly  20 - 1  that is disposed within the space formed between the antenna back body  20 - 2  and the interior wall of the front wall plate cover  300 - 4 . The circuit assembly  20 - 1  includes a printed circuit board (PCB)  20 - 4  that has various control circuits (not visible in this view) disposed on the back side thereof. The front side includes a shielding structure  20 - 6  that accommodates a plurality of antenna coils  20 - 10 . The shielding structure  20 - 6  prevents a magnetic field from heating any metallic structures behind the assembly  100  (e.g., a metallic device box or an electronic component). In the example shown in this view, the antenna is comprised of two coils,  20 - 10 - 1 , and  20 - 10 - 2  (in alternate embodiments, antenna may be comprised of a single coil arrangement ( 20 - 10 - 1 ), a double coil arrangement ( 20 - 10 - 2 ), or a three coil arrangement ( 20 - 10 - 1 ,  20 - 10 - 2 , and  20 - 10 - 3 )). 
     As embodied herein and depicted in  FIG. 34 , a schematic block diagram illustrating a wireless charging device with a lock-out timer circuit  3300  is disclosed. In one embodiment, the AC power (e.g., 120 VAC, 60 Hz) is provided to the power supply  10 - 16  via a power station enable switch S 1 . In another embodiment, the power station enable switch S 1  may be provided at the output of the power supply  10 - 16 . In the latter case, the position of the switch S 1  allows the user to turn off the wireless charger while, for example, the low voltage (e.g., USB) receptacle remains energized. See, e.g.,  FIG. 1A . S 1  may be provided on any suitable surface of the wall plate assembly  30  ( 300 ,  3000 ). See, e.g., switch  202 - 4  at  FIG. 25B . In any event, the power supply  10 - 16  is configured to convert AC power to one or more low voltage power supply signals in accordance with the requirements of the charger circuitry  20 - 1  and the charger coil(s)  20 - 10 . 
     The lockout circuit may include any suitable sensor configured to sense the operation of the charger coil(s)  20 - 10 . In one embodiment, the sensor may be realized by a resistive shunt that signals to the detector  3302  that the charger coil(s)  20 - 10  are pulling current (and thus operating). In another embodiment, the sensor may be implemented using a sensing coil that is configured to be magnetically coupled to the coils  20 - 10  when they are in operation. Briefly then, once the detector  3302  detects that sensor signal, it provides the delay timer  3304  with a detection signal. The delay timer is a type of filter and functions much like a de-bounce signal; it allows the lockout circuit  3300  to ignore sensor “sputtering” (e.g., momentary interruptions to the charging process) and noise so that the lockout timer is not prematurely activated. Once the detector signal is reasserted during the delay timer period, the delay timer  3304  will reset, otherwise it times out and sends a signal to the lockout timer  3306 . 
     When the lockout timer  3306  receives the signal from the delay timer  3304 , it opens a switch S 2  (electronic or mechanical) that decouples the circuit assembly  20 - 1  from power supply  10 - 16  for a predetermined interval so that the circuit assembly  20 - 1  cannot charge the battery. The predetermined interval may be in a range that includes 15 seconds, 30 seconds, one (1) minute or up to an hour. 
     The reason for the lockout timer  3300  is as follows. Many portable electronic devices are configured to provide an audible signal (e.g., a beep) that signals the user that its battery has been fully charged. However, once the battery charges, the battery voltage starts to decay. Even when the amount of decay is slight, the charger will recommence the charging process to bring the battery voltage back up to full charge. Each time the battery voltage is brought back up to full charge, the portable electronic device will provide the audible signal. Accordingly, the user may hear a series of beeping sounds every few seconds. The lockout circuit  3300  prevents this annoyance from occurring. 
     Note that with or without the lockout circuit  3300 , the switch S 1  may be configured to interrupt the power supply  10 - 16 , circuit assembly  20 - 1 , and/or the lock-out circuit  3300  when these elements are not in use. In another embodiment of the invention, the switch S 1  may be mechanically coupled to the reciprocating gripper  30 - 120  (see, e.g.,  FIG. 23A ). When a portable electronic device is disposed between the grippers, the switch S 1  may be closed to thus enable a charging sequence. When the portable electronic device  1  is removed, power may also be removed to terminate the charging sequence. 
     Referring to  FIG. 35 , a diagrammatic depiction of an electrical wiring assembly  100  in accordance with the present invention is disclosed. As shown herein, the electrical wiring assembly  100  may include an electrical wiring device  10  and a wireless charging facility  30  ( 300 ,  3000 ) disposed within a wall plate housing  30 - 1 . As described herein, the power supply  10 - 3  is configured to provide a low voltage signal to, e.g., one or more USB ports  10 - 8  (See, e.g.,  FIG. 1A ) and a low voltage signal to the wireless charging facility  30  ( 300 ,  3000 ). In this embodiment, the low voltage signal provided to the wireless facility  30  is a DC signal that can be modulated by the inverter disposed in charger  30 . The DC signal may be of any suitable voltage amount depending on the requirements of the charger circuit  20 - 1  (e.g., +5 VDC, +/−5 VDC, +12 VDC, +15 VDC, +/−15 VDC, +19 VDC, etc.). 
     As described herein, the circuit  20 - 1  typically includes an embedded controller  20 - 9  that is configured to drive the inverter in accordance with the system specification. The charging coil(s)  20 - 10  provide the embedded controller  20 - 9  with a feedback signal for closed-loop control of the inverters and the charging process. The embedded controller is coupled to a communication interface  20 - 11  that is configured to communicate with the portable device using a suitable communications channel (in-band or out-of-band). The term “out-of-band” refers to the use of a communications interface other than primary and secondary charging coils to establish communications between the portable device  1  and the assembly  100 . The communication interface may be implemented by any suitable wireline or wireless communications interface. For example, one embodiment of the communication interface employs a Bluetooth wireless communications protocol. 
     In one embodiment, the wireless charging station  30  is configured to employ magnetic induction charging. As those skilled in the art will appreciate, magnetic induction establishes an electromagnetic field in the primary coil(s)  20 - 10  to transfer energy to the secondary coil in portable device  1 . The embedded controller  20 - 9  modulates the primary coil(s)  20 - 10  to create an alternating electromagnetic field; the secondary coil in the portable device converts the electromagnetic field into electrical current to charge its battery. As those skilled in the art will further appreciate, the primary coil(s)  20 - 10  and the secondary coil—in close proximity—form an electrical transformer. Under the direction of the embedded controller  20 - 9 , the primary coil(s)  20 - 10  may be driven by any suitable time-varying drive signal such as, e.g., a sinusoidal signal, a square wave signal, an amplitude modulated signal, a frequency modulated signal, and a phase modulated signal or any other suitable drive signal. The present invention may be configured in accordance with any suitable system specification such as the so-called “Qi” standard for Wireless Power Transfer Specification (2013) developed by the Wireless Power Consortium. The Qi Wireless Power Transfer Specification is incorporated herein by reference as though fully set forth in its entirety, for a more detailed explanation of power transmitter designs A1-A18 and B1-B5 (See, e.g., pp. 11-111), System Control (see, e.g., pp. 123-137) and Communications Interfacing (see, e.g., pp. 139-148). 
     In one embodiment, the wireless charging station  30  is configured to employ resonant inductive coupling. As those skilled in the art will appreciate, an inductive charging system that uses resonant inductive coupling may charge a secondary coil that is located at a relatively greater distance. The primary coil(s)  20 - 10  and the secondary coil (in the portable device  1 ) are configured as resonant circuits that are tuned to resonate at the same frequency. Accordingly, the primary coil  20 - 10  and the secondary coil are tuned by capacitors connected across the windings to make two coupled LC circuits that operate as magnetically coupled resonators. The resonant frequency may be in the MHz range between, for example, 1 MHz and 30 MHz to enable efficient power transfer from the primary  20 - 10  to the secondary. 
     As before, the embedded controller is configured to drive the inverters using any suitable time-varying drive signal such as, e.g., a sinusoidal signal, a square wave signal, an amplitude modulated signal, a frequency modulated signal, and a phase modulated signal or any other suitable drive signal. The present invention may be configured in accordance with any suitable system specification such as the A4WP Wireless Power Transfer System Baseline System Specification (BSS) AW4P-S-0001 v. 1.3., published by the Alliance for Wireless Power Transfer (A4WP), November, 2014. The A4WP BSS Specification is incorporated herein by reference as though fully set forth in its entirety, for a more detailed explanation of the system design including system description, resonator designs, transmitter designs, power transfer specifications, networking and signaling (see, e.g., pp. 1-108). 
     Referring to  FIG. 36  there is shown a schematic block diagram of processing circuitry which may include embedded controller  20 - 9  and associated memory  20 - 12  that may be implemented in connection with antenna assembly  20  (and coil  20 - 10 ). Embedded controller  20 - 9  may be a microcontroller or other device suitable for executing program code stored in memory  20 - 12  as described below. Embedded controller  20 - 9  may be implemented using hardware, software, general purpose processors, signal processors, application specific integrated circuits (ASICs), field programmable gate array (FPGA) devices, customized integrated circuits and/or a combination thereof. Memory  20 - 12  may include RAM and/or ROM, wherein the ROM may store operational firmware or provide long-term data storage when the device is not powered, and RAM may provide quickly-accessible memory for use with the processor when antenna assembly is powered. Memory  20 - 12  may alternately be referred to as “computer-readable medium,” which as used herein, refers to any medium that participates in providing data and/or instructions to the processor for execution. One of ordinary skill in the art will appreciate that memory  20 - 12  may be included together with embedded controller  20 - 9 , for example, as an integrated-circuit or microcontroller. Alternately, memory  20 - 12  may be separate and apart from embedded controller  20 - 9  but coupled to the embedded controller  20 - 9  such that embedded controller  20 - 9  may access the program code stored in memory. Embedded controller  20 - 9  may further include I/O circuitry, communication interface circuitry, and be coupled together with memory  20 - 12  by a bus system. 
     Embedded controller  20 - 9  may be in further connection with coils  20 - 10 , a sensor  20 - 13 , and the communications interface  20 - 11 . As mentioned above, memory  20 - 12  may store program code necessary for operation of embedded controller  20 - 9 . Program code may include instructions to communicate with sensor  20 - 13 , wherein sensor  20 - 13  is configured to detect the presence of a phone. Sensor  20 - 13  may, for example, be in physical communication with device cradle  30 - 10  and may detect the weight of the portable mobile device is positioned on cradle  30 - 10  and notify (e.g., by sending a signal) embedded controller  20 - 9  that a portable mobile device is present. In another example, sensor  20 - 13  may detect the presence of a portable mobile device reactively by measuring the change in inductance or capacitance of a reactive element in response to a portable mobile device. Indeed, embedded controller  20 - 9  may not employ a separate sensor  20 - 13  at all, but may instead measure the inductance of electromagnetic coil  20 - 10 . 
     Embedded controller  20 - 9  may communicate with a portable mobile device via communications interface  20 - 11 . For example, embedded controller  20 - 9  may perform a “handshaking” operation with the portable mobile device, which may, among other things, notify embedded controller  20 - 9  of the type of device to be charged, authorize charging, and prepare the portable mobile device to be charged. Once embedded controller  20 - 9  ascertains the type of device to be charged, embedded controller  20 - 9  may configure, drive, or otherwise prepare electromagnetic coils  20 - 10  to transmit the correct frequency, voltage, etc., as is necessary to charge a device of the appropriate type. As mentioned above, memory  20 - 12  may store program code necessary for embedded controller  20 - 9  to suitably drive coils  20 - 10  (e.g., according to the relevant protocols) to charge the portable mobile device. 
     Communications interface  20 - 11  may also communicate with the portable electronic device to determine the present charge of the battery of the portable electronic device. For example, the portable electronic device may communicate to embedded controller  20 - 9  via the communications interface  20 - 11  that the battery of the portable device is completely charged. Appropriately notified, embedded controller  20 - 9  may instruct antenna assembly  20  to cease transmitting power to the portable device (or may otherwise disconnect circuit assembly  20 - 1  to cease transmitting power, by, for example, opening switches S 1  or S 2 ). Furthermore, once completely charged, embedded controller  20 - 9  may turn on an LED (not shown) to notify a user that the portable electronic device has completed charging. 
     Those skilled in the art will appreciate that the diagrammatic depiction of  FIG. 36  is suitable for various forms of wireless charging technology including magnetic resonance technology and magnetic induction technology. Magnetic resonance technology typically operates at a resonance frequency within the range of 1 MHz and 30 MHz and is described in greater detail in the Wireless Power Transfer System Baseline System Specification (BSS) AW4P-S-0001 published by the Alliance for Wireless Power Transfer (A4WP.) Magnetic induction technology operates at a lower frequency, e.g. within the range of 100 kHz to 200 kHz and is described in greater detail in the so-called “Qi” standard for Wireless Power Transfer Specification (2013) developed by the Wireless Power Consortium. 
     While several 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. 
     All references, including publications, patent applications, and patents, cited herein are hereby incorporated by reference to the same extent as if each reference were individually and specifically indicated to be incorporated by reference and were set forth in its entirety herein. 
     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. 
     The use of the terms “a” and “an” and “the” and similar referents in the context of describing the invention (especially in the context of the following claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context. The terms “comprising,” “having,” “including,” and “containing” are to be construed as open-ended terms (i.e., meaning “including, but not limited to,”) unless otherwise noted. The term “connected” is to be construed as partly or wholly contained within, attached to, or joined together, even if there is something intervening. 
     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. 
     It should also be understood that, unless clearly indicated to the contrary, in any methods claimed herein that include more than one step or act, the order of the steps or acts of the method is not necessarily limited to the order in which the steps or acts of the method are recited. 
     Approximating language, as used herein throughout the specification and claims, may be applied to modify any quantitative representation that could permissibly vary without resulting in a change in the basic function to which it is related. Accordingly, a value modified by a term or terms, such as “about” and “substantially”, are not to be limited to the precise value specified. In at least some instances, the approximating language may correspond to the precision of an instrument for measuring the value. Here and throughout the specification and claims, range limitations may be combined and/or interchanged; such ranges are identified and include all the sub-ranges contained therein unless context or language indicates otherwise. 
     The recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, and each separate value is incorporated into the specification as if it were individually recited herein. 
     All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g., “such as”) provided herein, is intended merely to better illuminate embodiments of the invention and does not impose a limitation on the scope of the invention unless otherwise claimed. 
     No language in the specification should be construed as indicating any non-claimed element as essential to the practice of the invention. 
     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, as set forth in the United States Patent Office Manual of Patent Examining Procedures, Section 2111.03. 
     It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit and scope of the invention.
