Abstract

Claims (30)

1. A portable cell phone, comprising:

an operation mode input or circuit;

means for determining a transmit power level of said portable cell phone based on said operation mode input or circuit; and

an option switch configured to allow a user to:

control said transmit power level independent of an operation mode of said portable cell phone; and

disengage a proximity regulation system.

2. The portable cell phone as recited in claim 1 wherein said transmit power level is for communications between said portable cell phone and a communications tower of a cellular telephone network.

3. The portable cell phone as recited in claim 1 wherein said operation mode input or circuit is a headset operation mode input.

4. The portable cell phone as recited in claim 1 wherein said operation mode input or circuit is a data transfer operation mode circuit.

5. The portable cell phone as recited in claim 1 wherein said transmit power level is a maximum transmit power level for said portable cell phone when said portable cell phone is operating in a headset operation mode based on said operation mode input or circuit.

6. The portable cell phone as recited in claim 1 wherein said transmit power level is a maximum transmit power level for said portable cell phone when said portable cell phone is operating in a data transfer operation mode based on said operation mode input or circuit.

7. The portable cell phone as recited in claim 1 wherein said option switch is configured to reduce said transmit power level upon activation thereof.

8. A proximity regulation system for use with a portable cell phone, comprising:

a power governing subsystem configured to determine a transmit power level of said portable cell phone based on a mode of operation thereof; and

an option switch configured to allow a user to engage and disengage said proximity regulation system.

9. The proximity regulation system as recited in claim 8 wherein said transmit power level is for communications between said portable cell phone and a communications tower of a cellular telephone network.

10. The proximity regulation system as recited in claim 8 wherein said mode of operation is a headset operation mode.

11. The proximity regulation system as recited in claim 8 wherein said mode of operation is a data transfer operation mode.

12. The proximity regulation system as recited in claim 8 wherein said transmit power level is maximum when said portable cell phone is operating in a headset operation mode.

13. The proximity regulation system as recited in claim 8 wherein said transmit power level is maximum when said portable cell phone is operating in a data transfer operation mode.

14. A proximity regulation system for use with a portable cell phone, comprising:

means for determining a transmit power level of said portable cell phone based on a mode of operation thereof; and

an option switch configured to allow a user to:

control said transmit power level independent of an operation mode of said portable cell phone; and

disengage said proximity regulation system.

15. The proximity regulation system as recited in claim 14 wherein said transmit power level is for communications between said portable cell phone and a communications tower of a cellular telephone network.

16. The proximity regulation system as recited in claim 14 wherein said transmit power level is limited to a predetermined maximum level.

17. The proximity regulation system as recited in claim 14 wherein said transmit power level is maximum when said portable cell phone is operating in a headset operation mode or a data transfer operation mode.

18. The proximity regulation system as recited in claim 14 wherein said mode of operation is based on a user of said portable cell phone.

19. The proximity regulation system as recited in claim 14 wherein said transmit power level is reduced based on input of said option switch.
