Abstract
The temperature of an operator circuit is measured. A relationship between the temperature of the operator circuit and characteristics of the operator circuit is determined. The relationship is applied to the measured temperature of the operator circuit to create an adjustment action. The detection threshold is adjusted by the adjustment action.
