Abstract
The adaptive temperature controller includes an ambient temperature sensor, a device for measuring resistance, an electrically-conductive material, a power supply, and a device for controlling power. In operation, the controller determines the resistance of material at or near ambient temperature. Based on such determination so long as voltage and power are known, the resistance of the material, and therefore its instant temperature is known. Additionally, the adaptive temperature controller determines the responsiveness of the electrically-conductive material to determine the predicted increase in temperature and rate of increase in temperature relative to increases in voltage, current or power. As a result the voltage or power may be instantly varied to produce near infinite control over material temperature.
