Patent ID: 8892269

Claim:
A method for power saving comprising: placing a thermal sensor into a low power state; detecting a trigger to wake the thermal sensor from the low power state; accessing a value indicating a measured state of the thermal sensor saved prior to the thermal sensor entering the low power state; adjusting the value by steps of n counting in a direction toward a target value, n being greater than 1, until an inflection point is reached, the inflection point indicating the value has passed the target value; and in response to reaching the inflection point, adjusting the value in an opposite direction toward the target value, wherein in response to waking, the thermal sensor performs accessing a value indicating a last measured state of the thermal sensor prior to the thermal sensor entering the low power state, adjusting the value with a fast count by adjustments of n counting in a direction toward a target value, n being greater than 1, until detection of an inflection point, the inflection point indicating the value has passed the target value, and in response to the inflection point detection, adjusting the value with a normal count by adjustments of 1 counting in an opposite direction toward the target value.
