Abstract

A wireless communicator, including a modem operable to transmit and receive voice communication phone calls, a power amplifier coupled with the modem operable to dynamically apply a variable gain factor to voice communications transmitted by the modem, to produce an appropriate power output, and a controller coupled with the modem including a radiation monitor operable to monitor the power output of the power amplifier, the controller being operable to restrict operation of the modem, based on data provided by the radiation monitor, when the cumulative power output produced by the power amplifier exceeds a pre-designated daily cumulative power limit.

Claims

1. A method for limiting radiation transmitted by a wireless communicator, comprising:

monitoring power output of a wireless communicator, the wireless communicator being used to send and receive voice communication phone calls;

determining if the cumulative power output exceeds a pre-designated daily cumulative power limit; and

restricting operation of the wireless communicator when said determining is affirmative, comprising limiting usage of the wireless communicator when the wireless communicator is not being used in a low radiation listening mode.

2. The method of claim 1 wherein the low radiation listening mode comprises using the wireless communicator with a hands-free speaker.

3. The method of claim 1 wherein the low radiation listening mode comprises using the wireless communicator with a low radiation headset.

4. The method of claim 3 wherein the low radiation Headset includes air-tube earphones.

5. The method of claim 3 wherein the low radiation headset includes wired earphones.

6. The method of claim 3 wherein the low radiation Headset includes a Bluetooth headset.

7. The method of claim 1 wherein said limiting usage of the wireless communicator includes restricting incoming and outgoing phone calls sent and received by the wireless communicator to one or more pre-designated phone numbers.

8. The method of claim 7 wherein the one or more pre-designated phone numbers comprise emergency phone numbers.

9. The method of claim 7 wherein the one or more pre-designated phone number comprise phone numbers of parents of a child who uses the wireless communicator.

10. The method of claim 1 further comprising issuing an alarm advising a user that a current call will be disconnected unless the user switches the wireless communicator to the low radiation listening mode.

11. The method of claim 1 further comprising calibrating the pre-designated daily cumulative power limit according to a user'"'"'s gender, age and weight.

12. The method of claim 1 further comprising directing a phone call through a hands-free speaker between the time that the phone call is made and the time when a person answers the phone call.
