Abstract:
1. A method for thermal mitigation in a portable computing device, the method comprising: monitoring a signal associated with an electronic element in the portable computing device, wherein the electronic element is a heat producing element, the signal is generated in response to an event other than a temperature measurement, and a correspondence exists between the signal and an amount of heat produced by the electronic element; determining that the signal has exceeded an initial threshold; in response to the signal exceeding the initial threshold, accumulating samples of the signal over a time interval; determining that a sum of values of the accumulated samples of the signal has exceeded a second threshold within the time interval; determining a thermal condition indicating excessive heat production in response to the sum of values of the accumulated samples of the signal exceeding the second threshold within the time interval; and performing a first action to mitigate heat production by the electronic element associated with the monitored signal, in response to the thermal condition indicating excessive heat production.
