Abstract

A handheld control device, such as an air mouse, for remotely operating a controlled device, such as a TV, computer (PC), VCR or digital satellite system is provided with a microprocessor. In order to conserve battery power, the microprocessor may be switched from a high power awake state in which the air mouse functions are performed, and a low power sleep state. Power is conserved through the use of conductive outer surfaces that form a switch that controls the awake/sleep state of the microprocessor. The holding of the remote control device in the hand of a user with a finger on a conductive control button awakens the microprocessor. Conversely, the microprocessor enters the sleep state once the user hand is removed from its operating position on the remote control device.

Claims

1. A remote control device for controlling a controllable device, comprising:

high power consuming circuitry controllable to enter either a relatively low power sleep mode or a relatively high power awake mode;

an actuation mechanism operable by a user to control the high power consuming circuitry to perform a remote controlling of the controllable device;

a conductive plate that contacts the user hand when the remote control device is held in the user hand; and

a switch circuit that causes the high power consuming circuitry to transition between the relatively lower power sleep mode and the relatively high power awake mode, in response to the user holding the remote control device and simultaneously contacting the conductive plate and the actuation mechanism, wherein the relatively high power awake mode enables the remote controlling of the controllable device.

2. The remote control device of claim 1, wherein the actuation mechanism is a control button.

3. The remote control device of claim 1, further including a grip portion for holding of the remote control device in the hand of the user.

4. The remote control device of claim 3, wherein the grip portion includes the conductive plate that contacts the user hand when the remote control device is held in the user hand, the conductive plate forming part of the switch circuit.

5. The remote control device of claim 4, wherein the actuation mechanism forms part of the switch circuit.

6. The remote control device of claim 5, wherein the actuation mechanism is made of conductive material and is a button.

7. The remote control device of claim 6, wherein the conductive material is a plastic.

8. The remote control device of claim 4, wherein the conductive plate is made of plastic.

9. The remote control device of claim 8, wherein the conductive plate is a battery door of the remote control device.

10. The remote control device of claim 6, wherein the high power consuming circuitry includes a microprocessor.

11. An air mouse for pointing and clicking at a controllable device to control the controllable device, the air mouse comprising:

a microprocessor controllable to enter either a relatively low power sleep mode or a relatively high power awake mode;

an actuation mechanism operable by a user to control the microprocessor to perform a remote controlling of the controllable device;

a conductive plate that contacts the user hand when the remote control device is held in the user hand; and

a switch circuit that causes the microprocessor to transition between the relatively lower power sleep mode and the relatively high power awake mode, in response to the user holding the air mouse and simultaneously contacting the conductive plate and the actuation mechanism, wherein the relatively high power awake mode enables the remote controlling of the controllable device.

12. The air mouse of claim 11, further including a grip portion for holding of the air mouse in the hand of the user.

13. The air mouse of claim 12, wherein the grip portion includes the conductive plate that contacts the user hand when the air mouse is held in the user hand, the conductive plate forming part of the switch circuit.

14. The air mouse of claim 13, wherein the actuation mechanism forms part of the switch circuit.

15. The air mouse of claim 14, wherein the actuation mechanism is made of conductive material and is a button.

16. The air mouse of claim 15, wherein the conductive material is a plastic.

17. The air mouse of claim 13, wherein the conductive plate is made of plastic.

18. The air mouse of claim 17, wherein the conductive plate is a battery door of the air mouse.
