Patent ID: 8378271

Claim:
A device comprising: a variable power supply; at least one component from a plurality of components that operates within a temperature range that includes a lowest operating temperature threshold; and a temperature control subsystem for attaining a temperature of the at least one component within the temperature range, the temperature control subsystem containing logic that: monitors the temperature and a temperature change of the at least one component; detects when the temperature of the at least one component is below the lowest operating temperature threshold; and in response to detecting the temperature of the at least one component, prior to operation of the at least one component, is below the lowest operating temperature threshold, automatically increases a level of voltage applied across the at least one component by the variable power supply to initiate an advanced preheating of the at least one component to within the temperature range, wherein the at least one component self generates an amount of heat proportional to an amount of quiescent leakage current by the at least one component, and wherein increasing of the level of voltage applied across the at least one component increases the quiescent leakage current.
