Abstract

A receiver device configured to charge a chargeable device is provided that includes an inductive region including at least one receiver coil for receiving magnetic flux from an inductive charging system and a conductive region including contacts for receiving electric power from a conductive charging system. The conductive region includes a first and a second plurality of contacts and a connector for transferring the electric power received from the inductive or conductive charging system to the chargeable device to charge the chargeable device.

Claims

1. A receiver device configured to charge a chargeable device, comprising:

an inductive region comprising at least one receiver coil for receiving magnetic flux from an inductive charging system;

a conductive region comprising contacts for receiving electric power from a conductive charging system, wherein the conductive region comprises a first and a second plurality of contacts; and

a connector for transferring the electric power received from the inductive or conductive charging system to the chargeable device to charge the chargeable device.

2. The receiver device of claim 1 wherein the first and second plurality of contacts are positioned on opposite sides of the inductive region.

3. The receiver device of claim 1, wherein the first plurality of contacts includes at least three contacts.

4. The receiver device of claim 1, wherein the first and second plurality of contacts are positioned proximate opposite ends of the receiver device.

5. The receiver device of claim 1 further comprising:

a plurality of magnets configured to increase force applied by the contacts to a surface of the conductive or inductive charging system.

6. The receiver device of claim 5, wherein the magnets are located substantially in close proximity to the perimeter of the receiver device and away from the receiver coil.

7. The receiver device of claim 1, further comprising:

a case formed to substantially fit and attach onto the chargeable device.

8. A sleeve configured to charge a chargeable device, comprising:

an inductive region for receiving wireless electric power from an inductive charging system;

a conductive region comprising contacts for receiving electric power from a conductive charging system; and

a connector for transferring the wireless power received from the wireless or conductive charging system to the chargeable device to charge the chargeable device.

9. The sleeve of claim 8, wherein the contacts are spaced across the sleeve.

10. The sleeve of claim 8, wherein the contacts are configured in a non-equilateral pattern in order to ensure charging of the chargeable device independent of orientation and location of the chargeable device in relation to the conductive charging system.

11. The sleeve of claim 8, wherein the contacts protrude from the receiver device.

12. The sleeve of claim 8, wherein the conductive region comprises a first and a second plurality of contacts.

13. The receiver device of claim 12, wherein the first and second plurality of contacts are positioned on opposite sides of the inductive region.

14. The receiver device of claim 12, wherein the first plurality of contacts includes at least three contacts.

15. The receiver device of claim 12, wherein the first and second plurality of contacts are positioned proximate opposite ends of the receiver device.

16. A receiver device configured to charge a chargeable device, comprising:

an inductive region comprising at least one receiver coil for receiving magnetic flux from an inductive charging system; and

a conductive region comprising contacts for receiving electric power from a conductive charging system.

17. The receiver device of claim 16, wherein the conductive region comprises a first plurality of contacts and a second plurality of contacts.

18. The receiver device of claim 17, wherein the first and second plurality of contacts are positioned on opposite sides of the inductive region.

19. The receiver device of claim 18, wherein the first and second plurality of contacts are positioned proximate opposite ends of the receiver device.

20. The receiver device of claim 19, further comprising:

a case formed to substantially fit and attach onto the chargeable device.
