Abstract

An interchangeable cover is endowed with one or more control keys and complementary electronics to add the control keys to an attached mobile device, which may e.g. be a wireless mobile phone. In one embodiment, the control keys are designed to be used with an alternate display orientation of the attached mobile device. In one embodiment, the control keys are control keys of a game pad. In one embodiment, the cover is U-shaped. In a wireless mobile phone embodiment, the cover is attached to a rotabable sub-section of a pivotable section.

9. The cover of claim 1, wherein the at least one control keys comprises a plurality of control keys, with a first and a second subset of the control keys disposed at different ends of an edge of cover body, designed for substantially current usage by a user with both hands.

10. The cover of claim 1, wherein the at least one control keys are designed to be used with an alternate display orientation of the attached mobile device.

11. The cover of claim 1, wherein the electronic component comprises an analog-to-digital (A/D) converter coupled to the traces, a storage unit coupled to the A/D converter and an input/output (I/O) interface coupled to the storage unit.

12. The cover of claim 11, wherein the storage unit comprises EEPROM.

13. The cover of claims 1, wherein the mobile device comprises functionalities of at least a selected one of a wireless mobile phone and a personal digital assistant.

14. The cover of claim 1, wherein the at least one control key is disposed on a first exterior surface of the cover body, and the cover further comprises at least one other input keys disposed on a second exterior surface of the cover body.

15. The cover of claim 14, wherein the cover body is U-shaped, with the first and second exterior surfaces being disposed on the different sides of the U-shape.

16. A mobile device comprising

a core unit including a plurality of input/control keys, at least one extension interface and a plurality of exterior surfaces disposed on different geometric planes;

and
