Abstract

Wireless power receiving apparatus 150 is retrofitted to a portable electrical device 100 to enable the device to receive power wirelessly. The apparatus comprises a power-receiving element 200 adapted to be attached to the device, e.g. by adhesive 201, and also being adapted to receive power wirelessly from a transmitter of power when the element and transmitter are in proximity with one another. One or more power connectors 203 are connected electrically to the power-receiving element and are adapted to be connected, when the apparatus is in use, to one or more corresponding power connectors 101 of the portable electrical device to deliver power received by the element to the device. The power-receiving element may be in the form of a sticker or may be carried by or incorporated in a replacement cover portion for the portable electrical device.

Claims

1. Wireless power receiving apparatus for use with a portable electrical device to enable the device to receive power wirelessly, the apparatus comprising:

a power-receiving element for receiving power wirelessly from a transmitter of power when said power-receiving element and the transmitter are in proximity with one another, wherein said power-receiving element is attached to an internal surface portion within the portable electrical device;

a power connector connected electrically to said power-receiving element and adapted to be connected to internal power contacts within the portable electrical device other than battery contacts to deliver power received by said power-receiving element to the portable electrical device, wherein said power connector includes power-conditioning circuitry operable to condition power received by said power-receiving element prior to delivery to the portable electrical device.

2. Wireless power receiving apparatus of claim 1 wherein said internal surface portion is a surface portion of a battery compartment of the portable electrical device.

3. Wireless power receiving apparatus of claim 1 wherein said power-receiving element is directly attached to the internal surface portion within the portable electrical device.

4. Wireless power receiving apparatus of claim 1 wherein said power-receiving element is a stamped coil.

5. Wireless power receiving apparatus of claim 1 wherein said power-receiving element is a pressed metal coil.

6. Wireless power receiving apparatus of claim 1 wherein said power-conditioning-circuitry includes circuitry capable of converting alternating current delivered by said power receiving element into power suitable for use in the portable electronic device.

7. A portable electrical device comprising:

internal power contacts within the portable electrical device other than battery contacts;

a wireless power receiving apparatus to enable said portable electrical device to receive power wirelessly, said wireless power receiving apparatus including

a power-receiving element for receiving power wirelessly from a transmitter of power when said portable electrical device and the transmitter are in proximity with one another,

a power connector connected electrically to said power-receiving element and connected to said internal power contacts to deliver power received by said power-receiving element to said portable electrical device.

8. Wireless power receiving apparatus of claim 7 including an internal surface wherein said power-receiving element is attached to a portion of said internal surface of said device.

9. The portable electrical device of claim 7 wherein said power-receiving element is a stamped coil.

10. The portable electrical device of claim 7 wherein said power-receiving element is a pressed metal coil.

11. The portable electrical device of claim 7 wherein said power connector includes power-conditioning circuitry operable to condition power received by said power-receiving element prior to delivery to the portable electrical device

12. The portable electrical device of claim 11 wherein said power-conditioning-circuitry includes circuitry capable of converting alternating current delivered by the power receiving element into power suitable for use in the portable electronic device.

13. A portable electrical device comprising:

a battery including battery contacts;

internal power contacts within said portable electrical device other than said battery contacts of said battery;

a wireless power receiving apparatus to enable the portable electrical device to receive power wirelessly, said wireless power receiving apparatus including

a power-receiving element for receiving power wirelessly from a transmitter of power when said portable electrical device and the transmitter are in proximity with one another; and

a power connector connected electrically to said power-receiving element and connected to said internal power contacts to deliver power received by said power-receiving element through said internal power contacts and through said battery contacts to said battery.

14. Wireless power receiving apparatus of claim 13 including an internal surface wherein said power-receiving element is attached to a portion of said internal surface of said device.

15. The portable electrical device of claim 13 wherein said power-receiving element is a stamped coil.

16. The portable electrical device of claim 13 wherein said power-receiving element is a pressed metal coil.

17. The portable electrical device of claim 13 wherein said power connector includes power-conditioning circuitry operable to condition power received by said power-receiving element prior to delivery to said battery.

18. The portable electrical device of claim 17 wherein said power-conditioning-circuitry includes circuitry capable of converting alternating current delivered by the power receiving element into power suitable for use in the portable electronic device.
