Patent ID: 7442902

Claim:
An adaptive temperature controller for simultaneous temperature measurement and control for use with an electrically-conductive material to heat a system component, comprising: a temperature sensor, said temperature sensor determining the temperature of said electrically-conductive material; a device for measuring resistance, said device for measuring resistance recording measurement of two members of the group consisting of power, current and voltage; said device for measuring resistance determining resistance of said electrically-conductive material by application of Ohm's Law to said two members of the group consisting of power, current and voltage; a power supply, said power supply in electrical communication with said electrically-conductive material said electrically-conductive material altering temperature based on said electrical communication from said power supply; a device for controlling the output of said power supply, said device for measuring resistance outputting said determination of the resistance of said electrically-conductive material to said device for controlling the output of said power supply, said temperature sensor outputting the determination of the temperature of said electrically-conductive material to said device for controlling the output of said power supply; said device for controlling the output of said power supply determining the thermal coefficient of resistance of said electrically-conductive material based on the output of said device for measuring resistance and the output of said temperature sensor; said device for controlling the output of said power supply controlling the temperature of said electrically-conductive material based on the output of one of the group of power, voltage or current.
