Abstract

Various disclosed embodiments include illustrative systems, structures, and methods. In an illustrative embodiment, a system includes a power transmitter operably couplable to a source of electrical power and configured to wirelessly transmit electrical power and a power receiver alignable with the power transmitter on an opposing side of a non-conductive panel of a structure. The power receiver is configured to generate electrical power responsive to the electrical power wirelessly transmitted by the power transmitter.

First claim

What is claimed is:

1. A system comprising:
a power transmitter operably couplable to a source of electrical power and configured to wirelessly transmit electrical power, wherein the power transmitter comprises a transmission coil disposed in a power transmitter housing and a plurality of magnets coupled to the power transmitter housing adjacent to the transmission coil; and
a power receiver alignable with the power transmitter on an opposing side of a panel of a structure and configured to generate electrical power responsive to the electrical power wirelessly transmitted by the power transmitter, wherein the power receiver comprises a receiver coil disposed in a power receiver housing and a plurality of magnets coupled to the power receiver housing adjacent to the receiver coil;
wherein the power receiver is alignable with the power transmitter by attraction of the plurality of magnets coupled to the power receiver housing to the plurality of magnets coupled to the power transmitter housing through the panel.

2. The system of claim 1 , further comprising a suction device couplable to at least one device chosen from the power transmitter and the power receiver and configured to provide an attaching force to the panel.

3. The system of claim 1 , wherein the power receiver includes an electrical power outlet.

4. The system of claim 1 , wherein the transmission coil is a first electrically conductive coil configured to:
receive a magnitude varying current; and
generate a changing electromagnetic field responsive to the received magnitude varying current.

5. The system of claim 4 , wherein the receiver coil is a second electrically conductive coil configured to allow an electromotive force to be induced responsive to the changing electromagnetic field generated by the first electrically conductive coil.

6. A structure comprising:
a source of electrical power;
a panel configured to separate an interior of the structure from an exterior of the structure; and
a system including:
a power transmitter operably couplable to a source of electrical power and configured to wirelessly transmit electrical power, wherein the power transmitter comprises a transmission coil disposed in a power transmitter housing and a plurality of magnets coupled to the power transmitter housing adjacent to the transmission coil; and
a power receiver alignable with the power transmitter on an opposing side of a panel of a structure and configured to generate electrical power responsive to the electrical power wirelessly transmitted by the power transmitter, wherein the power receiver comprises a receiver coil disposed in a power receiver housing and a plurality of magnets coupled to the power receiver housing adjacent to the receiver coil;
wherein the power receiver is alignable with the power transmitter by attraction of the plurality of magnets coupled to the power receiver housing to the plurality of magnets coupled to the power transmitter housing through the panel.

7. The structure of claim 6 , wherein the system further includes a suction device couplable to at least one device chosen from the power transmitter and the power receiver and configured to provide an attaching force to the panel.

8. The structure of claim 6 , wherein the power receiver includes an electrical power outlet.

9. The structure of claim 6 , wherein the transmission coil is a first electrically conductive coil configured to:
receive a magnitude varying current; and
generate a changing electromagnetic field responsive to the received magnitude varying current.

10. The structure of claim 9 , wherein the receiver coil is a second electrically conductive coil configured to allow an electromotive force to be induced by the changing electromagnetic field generated by the first electrically conductive coil.

11. A method comprising:
aligning a power receiver with a power transmitter on opposing sides of a panel of a structure, wherein the power receiver is aligned with the power transmitter by attraction of a plurality of magnets coupled to a power receiver housing adjacent to a receiver coil to a plurality of magnets coupled to a power transmitter housing adjacent to a transmission coil through the panel;
operably coupling the power transmitter to a source of electrical power;
wirelessly transmitting electrical power from the power transmitter to the power receiver; and
generating electrical power by the power receiver responsive to the electrical power transmitted by the power transmitter.

12. The method of claim 11 , further comprising magnetically coupling the power transmitter and the power receiver on opposing sides of a panel of a structure.

13. The method of claim 11 , further comprising attaching at least one device chosen from the power transmitter and the power receiver to a panel of a structure using a suction device.

14. The method of claim 11 , wherein wirelessly transmitting electrical power includes:
receiving a magnitude varying current at the transmission coil comprising a first electrically conductive coil; and
generating a changing electromagnetic field around the first electrically conductive coil responsive to the received magnitude varying current.

15. The method of claim 14 , wherein generating electrical power further includes inducing an electromotive force at the receiver coil comprising a second electrically conductive coil responsive to the changing electromagnetic field.
