Abstract

A device is provided which comprises (a) a portable computer (13) having first and second major opposing surfaces and having a display (31) disposed on the first major surface, and (b) a protective cover (11) adapted to releasably engage the computer in a first orientation in which it covers the display. The cover has a removable battery pack (37) disposed therein.

Claims

1. A device, comprising:

a portable computer having first and second major opposing surfaces and having a display disposed on said first major surface; and

a protective cover adapted to releasably engage said computer in a first orientation in which it covers said display, said cover having a battery pack disposed therein.

2. The device of claim 1, wherein said computer is a tablet PC.

3. The device of claim 1, wherein said cover is further adapted to releasably engage said computer in a second orientation in which it does not cover said display.

4. The device of claim 1, wherein said cover is further adapted to releasably engage said computer in a second orientation in which it covers said second major surface.

5. The device of claim 4, wherein said battery pack is in electrical communication with the internal circuitry of said computer when said cover is in the second orientation.

6. The tablet PC of claim 5, wherein said battery pack is removable from the exterior surface of said cover when said cover is in the second orientation.

7. The device of claim 1, wherein said cover has a plurality of battery packs disposed therein.

8. The device of claim 1, wherein each battery pack comprises a plurality of batteries.

9. The device of claim 1, wherein said cover releasably engages said battery pack.

10. The device of claim 1, wherein said cover has a depression therein which releasably engages said battery pack.

11. The device of claim 1, wherein said battery pack has an indicator thereon which indicates the degree to which the battery is charged.

12. The device of claim 1, wherein said cover has first and second opposing ends, wherein said first end has a plurality of protrusions adapted to engage a lip disposed on a first side of said computer, and wherein said second end has a protrusion adapted to engage a depression in a second side of said computer.

13. The device of claim 1, wherein said cover is adapted to power a peripheral device.

14. The device of claim 13, wherein said peripheral device is a disk drive.

15. The device of claim 13, wherein said peripheral device is a cell phone.

16. The device of claim 15 in combination with a cell phone.

17. The device of claim 1, wherein said computer has internal batteries, wherein said cover is adapted to be connected to an external power source and to thereby recharge the battery pack disposed in said cover, and wherein said cover is further adapted to recharge the internal batteries of the computer.

18. The device of claim 1, wherein said battery pack is removable.

19. The device of claim 1, wherein said cover is removable.

21. The tablet PC of claim 18, wherein said battery pack is removable from the exterior surface of said cover when said cover is in the second orientation.

22. The tablet PC of claim 18, wherein said cover is adapted to power a peripheral device.

23. The tablet PC of claim 18, wherein said peripheral device is a cell phone.

24. The tablet PC of claim 18, wherein said cover is adapted to provide AC power to a peripheral device.

25. The tablet PC of claim 18, wherein said PC has internal batteries, wherein said cover is adapted to be connected to an external power source and to thereby recharge the battery pack disposed in said cover, and wherein said cover is further adapted to recharge the internal batteries of the computer.

26. The tablet PC of claim 18, wherein said battery pack is removable from said cover.

20. A tablet PC, comprising:

a chassis having first and second major opposing surfaces and having a display disposed on said first major surface;

a protective cover adapted to releasably engage said PC in a first orientation in which it covers said display, and being further adapted to releasably engage said PC in a second orientation in which it covers said second major surface; and

a battery pack disposed in said cover;

wherein said battery pack is in electrical communication with the internal circuitry of said tablet PC when the cover is in the second orientation.
