Claim Text:
1. A method comprising: receiving, by a user device, a command to wirelessly transmit information to a wireless communication system at a transmit power level specified by the wireless communication system; computing, by the user device, a moving sum of transmit power levels used to transmit previous information within a moving window, wherein the moving sum of the transmit power levels is a summed total of the transmit power levels used within the moving window, and wherein the moving window spans a time period extending backward in time from a current time at which the moving sum is computed to a previous time that is a specified temporal distance from the current time; determining, by the user device, whether transmitting the information at the specified transmit power level using a first duty cycle will cause the moving sum to exceed a predetermined percentage of a maximum accumulated power level, wherein the predetermined percentage is less than 100% of the maximum accumulated power level, the maximum accumulated power level representing a maximum amount of radiation that the user device will expose a user to in a specified time period, wherein the first duty cycle comprises a first ratio of active periods during which the user device is to transmit data to inactive periods during which the user device is not to transmit data; responsive to determining that transmitting the information at the specified transmit power level using the first duty cycle will cause the moving sum to exceed the predetermined percentage of the maximum accumulated power level, performing the following comprising: detecting whether a portion of a user's body is within a predetermined distance from an antenna of the user device; and determining whether transmitting the information at the specified transmit power level using the first duty cycle will cause the moving sum to exceed the predetermined percentage of the maximum accumulated power level when the portion of the user's body is detected.
