Abstract

A wireless power supply includes a source magnetic resonator, connected to a power source and configured to exchange power wirelessly via a wireless power transfer signal with at least one device magnetic resonator integrated into at least one peripheral component of a computer and a processor configured to adjust the operating point of the wireless power supply wherein power is transferred non-radiatively from the wireless power supply to the at least one device magnetic resonator and wherein the power supply forms a part of the computer.

Claims (31)

1. A wireless power supply comprising;

a source magnetic resonator, connected to a power source and configured to exchange power wirelessly via a wireless power transfer signal with at least one device magnetic resonator integrated into at least one peripheral component of a computer; and

a processor configured to adjust the operating point of the wireless power supply wherein power is transferred non-radiatively from the wireless power supply to the at least one device magnetic resonator and wherein the power supply forms a part of the computer.

2. The wireless power supply of claim 1 , wherein the processor is configured to adjust a frequency of the wireless power transfer signal.

3. The wireless power supply of claim 1 , wherein the processor is configured to adjust an impedance matching network of the wireless power supply.

4. The wireless power supply of claim 1 , wherein the processor is configured to adjust a power converter of the wireless power supply.

5. The wireless power supply of claim 1 , wherein the processor is configured to adjust an amplifier of the wireless power supply.

6. The wireless power supply of claim 1 , wherein the wireless power supply is configured to send wireless control signals to the at least one device resonator.

7. The wireless power supply of claim 1 , wherein the wireless power supply is configured to receive wireless signals from the at least one device resonator.

8. The wireless power supply of claim 1 , wherein integrated device magnetic resonator comprises power and control circuitry.

9. The wireless power supply of claim 8 , wherein the device magnetic resonator power and control circuitry comprises a processor.

10. The wireless power supply of claim 9 , wherein the device magnetic resonator processor is configured to provide information to the wireless power supply.

11. The wireless power supply of claim 1 , wherein the at least one computer peripheral comprises at least one energy storage unit.

12. The wireless power supply of claim 11 , wherein the at least one energy storage unit is a battery.

13. The wireless power supply of claim 11 , wherein the at least one energy storage unit is a supercapacitor.

14. The wireless power supply of claim 1 , wherein the processor controls a battery charging circuit of at least one computer peripheral.

15. The wireless power supply of claim 1 , further comprising at least one repeater resonator.

16. The wireless power supply of claim 15 , wherein the at least one device magnetic resonator is configured to operate as a wireless source to at least one other magnetic resonator in an active area.

17. A wirelessly powered computer peripheral, comprising:

a tunable device magnetic resonator;

a means for transferring information wirelessly;

and a means for adjusting a parameter of the tunable device resonator;

wherein the peripheral is selected from the group consisting of a keyboard, a mouse and a touch surface.

18. A wirelessly powered computer peripheral, comprising:

a magnetic resonator,

wherein the magnetic resonator is configurable to operate as a device resonator for capturing energy and delivering power to the computer peripheral in a first active area and as a repeater resonator for improving energy transfer to another computer peripheral in a second active area.

19. The computer peripheral from claim 18 , wherein the magnetic resonator is configurable to operate simultaneously as a device resonator and a repeater resonator.

20. The computer peripheral from claim 18 , wherein the magnetic resonator is periodically switched from a repeater function to an energy capture function.

21. The computer peripheral from claim 18 , wherein the peripheral comprises a keyboard.

22. The computer peripheral from claim 18 , wherein the peripheral comprises a monitor.

23. The computer peripheral from claim 18 , wherein the peripheral comprises a touch screen.
