Abstract

An apparatus comprising a connector, at least one cover member, and at least one wireless charging antenna is provided. The connector is configured to interface with at least a charging connector of a mobile device, and the at least one cover member is configured to extend away from the mobile device in an opened configuration. The at least one wireless charging antenna is physically coupled to the cover member and electrically coupled to the connector. The charging antenna is configured to receive a wireless transmission of electricity and to deliver the electricity via the connector to charge or power the mobile device.

Claims

1. An apparatus comprising:

a connector configured to interface with at least a charging connector of a mobile device;

at least one cover member configured to extend away from the mobile device in an opened configuration; and

at least one wireless charging antenna physically coupled to the at least one cover member and electrically coupled to the connector, the at least one charging antenna configured to receive a wireless transmission of electricity and to deliver the electricity via the connector to charge or power the mobile device.

2. The apparatus of claim 1, wherein the at least one cover member is configured to support the mobile device in an upright orientation in the opened configuration.

3. The apparatus of claim 1, wherein the at least one cover member is configured to cover a display of the mobile device in a closed configuration.

4. The apparatus of claim 1, wherein the at least one cover member comprises two or more hingeably coupled cover members, wherein the at least one wireless charging antenna comprises two or more wireless charging antennas each physically coupled to respective ones of the cover members.

5. The apparatus of claim 4, wherein the apparatus is capable of being moved between first and second orientations in the opened configuration, wherein a different one of the two or more wireless charging antennas is proximate a charger in the first and second orientations.

6. The apparatus of claim 1, further comprising a battery electrically coupled to at least the connector.

7. The apparatus of claim 1, further comprising a second charging antenna physically coupled to the at least one cover member and electrically coupled to the connector and configured to couple to a second charging connector of a second mobile device, the second charging antenna configured to deliver at least a portion of the electricity to the second mobile device via the second connector.

8. The apparatus of claim 1, wherein the connector is further configured to couple to a data connector of the mobile device, the apparatus further comprising a circuit coupled to the data connector and configured to provide status of the apparatus to the mobile device.

9. An apparatus comprising:

a connector configured to interface with at least a charging connector of a mobile device;

at least one cover member; and

at least one wireless charging antenna physically coupled to the at least one cover member and electrically coupled to the connector, the at least one charging antenna configured to receive a wireless transmission of electricity and to deliver the electricity via the connector to charge or power the mobile device.

10. The apparatus of claim 9, wherein the at least one cover member is configured to support the mobile device in an upright orientation in an opened configuration while the apparatus is charging or powering the mobile device.

11. The apparatus of claim 9, wherein the at least one cover member is configured to cover a display of the mobile device in a closed configuration while the apparatus is charging or powering the mobile device.

12. The apparatus of claim 9, wherein the at least one cover member comprises two or more hingeably coupled cover members, wherein the at least one wireless charging antenna comprises two or more wireless charging antennas each physically coupled to respective ones of the cover members.

13. The apparatus of claim 12, wherein the apparatus is capable of being moved between first and second orientations in an opened configuration, wherein a different one of the two or more wireless charging antennas is proximate a charger in the first and second orientations.

14. The apparatus of claim 9, wherein the connector is configured to attach the apparatus to the mobile device.

15. The apparatus of claim 9, further comprising a second charging antenna physically coupled to the at least one cover member and electrically coupled to the connector and configured to couple to a second charging connector of a second mobile device, the second charging antenna configured to deliver at least a portion of the electricity to the second mobile device via the second connector.

16. A method comprising:

attaching a cover to a mobile device to electrically couple at least one wireless charging antenna of the cover to a charging connector of the mobile device;

deploying the cover to an opened configuration; and

placing at least one member of the cover proximate a charger that wirelessly provides electricity to the at least one wireless charging antenna, and in response thereto, delivering the electricity to the mobile device to power or charge the mobile device.

17. The method of claim 16, wherein deploying the cover comprises folding at least two hinged members of the cover, and wherein the cover supports the mobile device in an upright orientation in the opened configuration.

18. The method of claim 16, wherein deploying the cover comprises folding at least two hinged members of the cover, and wherein the cover supports the mobile device in a reclined orientation in the opened configuration.

19. The method of claim 16, wherein deploying the cover comprises extending at least one member of the cover that comprises the at least one wireless charging antenna away from the mobile device.

20. The method of claim 16, wherein delivering the electricity to the mobile device comprises delivering the electricity while the mobile device is being used.
