METHOD AND SYSTEM TO MINIMIZE RADIATION EXPOSURE FROM MOBILE PHONES AND DEVICES

摘要

[0089] Mobile devices may minimize the radiation exposure to users by controlling the distance between the user, specifically the head, and the mobile device to a minimum distance. The reduction in exposure is realized due to the operation of the Inverse Square Rule on electromagnetic signal from the mobile device recognizing there is a steep fall off of signal strength resultant from increased distance between the head of the user and the source of the signal. Embodiments increase and maintain operational distance between the user and the broadcast device to reduce signal absorption. Enabled mobile devices increase and maintain the operational distance by detecting when the distance is breached by a variety of methods and then alerting the user. Sound and electromagnetic waves may be used to determine the proximity of the mobile device to the user, in addition image processing typically resident on some mobile devices may also be used to determine proximity to the user. Embodiments disable harmful features such as broadcasting when the operation distance is breached for a period of time or the radiation exposure exceeds a threshold. Other embodiments enforce the operational distance with physical barriers preventing the distance from being reduced. Embodiments influence the user to maintain a minimum distance via alerts, interruptions and warnings. Thus maintaining a minimum distance between the user and the transmitter may have a dramatic practical effect.
