Abstract

A portable electronic device includes a portable housing, and a battery and pointing device carried by the portable housing. The portable electronic device further includes electronic circuitry carried by the portable housing and connected to the battery and the pointing device. The electronic circuitry may switch from a sleep mode to an active mode based upon operation of the pointing device in a non-random pattern, and not switch from the sleep mode to the active mode based upon operation of the pointing device in a random pattern.

Claims

1. A portable electronic device comprising:

a portable housing;

a battery carried by said portable housing;

a pointing device carried by said portable housing; and

electronic circuitry carried by said portable housing and connected to said battery and said pointing device, said electronic circuitry being switchable from a sleep mode to an active mode based upon operation of said pointing device in a non-random pattern and not switching from the sleep mode to the active mode based upon operation of said pointing device in a random pattern.

2. The portable electronic device according to claim 1 wherein the non-random pattern corresponds to manipulation of said pointing device at a uniform speed and in a uniform direction.

3. The portable electronic device according to claim 2 wherein the non-random pattern further corresponds to manipulation of said pointing device for at least a threshold distance.

4. The portable electronic device according to claim 3 wherein said pointing device comprises a trackball.

5. The portable electronic device according to claim 4 wherein the threshold distance corresponds to rotation of said trackball for at least one hundred degrees.

6. The portable electronic device according to claim 1 wherein said pointing device comprises at least one of a trackball, a joystick, a trackwheel, and a touchpad.

7. The portable electronic device according to claim 1 wherein said electronic circuitry comprises a processor and a power management module cooperating therewith.

8. The portable electronic device according to claim 1 wherein said electronic circuitry comprises a wireless transceiver.

9. The portable electronic device according to claim 1 wherein said electronic circuitry comprises a processor performing at least one of email and scheduling functions.

10. The portable electronic device according to claim 1 wherein said pointing device is exposed on an outer surface of said housing.

11. An electronic device comprising:

a portable housing;

a battery carried by said portable housing;

a trackball carried by said portable housing and exposed on an outer surface thereof; and

electronic circuitry carried by said portable housing and connected to said battery and said trackball, said electronic circuitry being switchable from a sleep mode to an active mode based upon operation of said trackball in a non-random pattern corresponding to manipulation of said trackball at a uniform speed and in a uniform direction, and not switching from the sleep mode to the active mode based upon operation of said trackball in a random pattern.

12. The portable electronic device according to claim 11 wherein the non-random pattern further corresponds to manipulation of said trackball for at least a threshold distance.

13. The portable electronic device according to claim 12 wherein the threshold distance corresponds to rotation of said trackball for at least one hundred degrees.

14. The portable electronic device according to claim 11 wherein said electronic circuitry comprises a processor and a power management module cooperating therewith.

15. The portable electronic device according to claim 11 wherein said electronic circuitry comprises a wireless transceiver.

16. The portable electronic device according to claim 11 wherein said electronic circuitry comprises a processor performing at least one of email and scheduling functions.

17. A method of power management for a portable electronic device comprising a portable housing, a battery and pointing device carried by the portable housing, and electronic circuitry carried by the portable housing and connected to the battery and the pointing device, the method comprising:

switching the electronic circuitry from a sleep mode to an active mode based upon operation of the pointing device in a non-random pattern; and

not switching the electronic circuitry from the sleep mode to the active mode based upon operation of the pointing device in a random pattern.

18. The method according to claim 17 wherein the non-random pattern corresponds to manipulation of the pointing device at a uniform speed and in a uniform direction.

19. The method according to claim 18 wherein the non-random pattern further corresponds to manipulation of the pointing device for at least a threshold distance.

20. The method according to claim 19 wherein the pointing device comprises a trackball.

21. The method according to claim 20 wherein the threshold distance corresponds to rotation of the trackball for at least one hundred degrees.

22. The method according to claim 17 wherein the pointing device comprises at least one of a trackball, a joystick, a trackwheel, and a touchpad.

23. The method according to claim 17 wherein the electronic circuitry comprises a processor and a power management module cooperating therewith.

24. The method according to claim 17 wherein the electronic circuitry comprises a wireless transceiver.

25. The method according to claim 17 wherein the electronic circuitry comprises a processor performing at least one of email and scheduling functions.

26. The method according to claim 17 wherein the pointing device is exposed on an outer surface of the housing.
