Patent ID: 8538351

Claim:
A radiation power level control method for a wireless user equipment (UE) device, said method comprising: determining that a current transmission event involving said wireless UE device occurred within a predetermined duration from a last transmission event; responsive to said determining, using a power data history associated with said wireless UE device in determining one or more Specific Absorption Rate (SAR) values during said current transmission event, said power data history comprising data tracked over a time window relative to one or more variables; if said current transmission event occurred outside said predetermined duration from said last transmission event, resetting said power data history and using said reset power data history in determining said one or more SAR values during said current transmission event; and if at least one of said one or more SAR values exceeds a threshold, effectuating a control action relative to said current transmission event, said control action including at least reducing a transmission power level radiating from at least one radio frequency (RF) antenna of said wireless UE device.
