Abstract

In some examples, a mobile device includes a radiation sensor configured to measure an amount of radiation surrounding a corresponding device that is communicatively connected to a second device and/or a third device, a comparator configured to compare the measured amount of radiation to a predetermined radiation threshold, a wireless communication manager configured to report to the second device and/or the third device a result output from the comparison module, and a collaboration manager configured to collaborate with the second device.

First claim

We claim:

1 . A method to reduce radiation surrounding a first device, comprising:
measuring, at least once within a predetermined period of time, an amount of radiation surrounding a first device that is communicatively connected to a second device; comparing the measured amount of radiation to a predetermined radiation threshold; and in response to the measured amount of radiation being greater than or equal to the predetermined radiation threshold:
reporting, to the second device, the measured amount of radiation, and
collaborating with the second device to reduce the amount of radiation surrounding the first device.

2 . The method of claim 1 , wherein the measured amount of radiation corresponds to an amount of radiation corresponding to signals received from the second device.

3 . The method of claim 2 , wherein the measured amount of radiation is greater than or equal to the predetermined radiation threshold for a predetermined number of times during the predetermined period of time.

4 . The method of claim 1 , further comprising in response to the measured amount of radiation being less than the predetermined radiation threshold, switching the first device to a normal radiation mode.

5 . The method of claim 4 , further comprising in response to the measured amount of radiation being less than the predetermined radiation threshold, instructing the second device to switch to a normal radiation mode.

6 . The method of claim 1 , wherein the collaborating comprises alternating, with the second device, between operating in a currently used communication protocol and operating in a secondary communication protocol in consecutive time frames over a subsequent predetermined period.

7 . The method of claim 6 , wherein the operating in the secondary communication protocol comprises emitting a lower amount of radiation than when operating in the currently used communication mode.

8 . The method of claim 1 , wherein the collaborating comprises alternating, with the second device, between operating in the currently used communication protocol and operating in the secondary communication protocol within a common time frame over a subsequent predetermined period.

9 . The method of claim 7 ,
wherein the collaborating reduces the amount of radiation by (V+1)/2V, and wherein V is a spreading factor that, when applied to operation in the secondary communication protocol, produces similar transmission performance as the currently used communication protocol.

10 . The method of claim 8 , wherein the operating in the secondary communication protocol includes emitting a lower amount of radiation than when operating in the currently used communication mode.

11 . The method of claim 6 , wherein the currently used communication protocol is orthogonal frequency division multiplexing (OFDM).

12 . The method of claim 6 , wherein the secondary communication mode is Code Division Multiple Access (CDMA).

13 . The method of claim 1 , wherein the collaborating comprises multiplying a transmit signal by an adaptive radiation control factor to control a radiation amount of the transmit signal.

14 . The method of claim 1 , further comprising:
measuring, one or more times, the amount of radiation surrounding the first device during the collaborating; comparing the amount of radiation measured during the collaborating to the predetermined radiation threshold; and responsive to the amount of radiation measured during the collaborating being less than the predetermined radiation threshold, instructing the second device to return to the currently used communication protocol.

15 . A non-transitory computer-readable medium storing executable instructions that, in response to being executed, cause a processor to perform operations to reduce radiation surrounding a first device, the operations comprising:
measuring an amount of radiation, emitted from a plurality of devices, surrounding a first device of the plurality of devices; comparing the measured amount of radiation to a predetermined radiation threshold; and in response to the measured amount of radiation being greater than or equal to the predetermined radiation threshold:
reporting, to the plurality of devices, the measured amount of radiation, and
dividing the plurality of devices into pairs of devices to respectively collaborate with each other to reduce the amount of radiation surrounding the first device.

16 . The non-transitory computer-readable medium of claim 15 , further in response to the measured amount of radiation being greater than or equal to the predetermined radiation threshold, instructing a first and second pair of the pairs of devices to alternate between operating in a currently used communication protocol and operating in a secondary communication protocol in consecutive time frames over a subsequent predetermined period.

17 . The non-transitory computer-readable medium of claim 15 , further in response to the measured amount of radiation being greater than or equal to the predetermined radiation threshold, instructing a first and second device of a first pair of the pairs of devices to alternate between a currently used communication protocol and a secondary communication protocol in consecutive time frames over another predetermined period.

18 . An apparatus, comprising:
a radiation sensor configured to measure an amount of radiation surrounding a corresponding device that is communicatively connected to a second device; a comparator configured to compare the measured amount of radiation to a predetermined radiation threshold; a wireless communication manager configured to report to the second device the measured amount of radiation from the comparison module; and a collaboration manager configured to collaborate with the second device to reduce the amount of radiation surrounding the corresponding device.

19 . The apparatus of claim 18 , wherein the collaborating comprises alternating, with the second device, between operating in a currently used communication protocol and operating in a secondary communication protocol in consecutive time frames over a predetermined period.

20 . The apparatus of claim 18 , wherein the collaborating comprises alternating, with the second device, between operating in the currently used communication protocol and operating in the secondary communication protocol within a common time frame over the predetermined period.

21 . A system, comprising:
a first device communicatively connected to a second device, the first device configured to:
measure, at least once within a predetermined period of time, an amount of radiation surrounding the first device;
compare the measured amount of radiation to a predetermined radiation threshold; and
in response to the measured amount of radiation being greater than or equal to the predetermined radiation threshold:
report, to the second device, the measured amount of radiation, and
collaborate with the second device to reduce the amount of radiation surrounding the first device.
