Title:
ADAPTIVE THERMAL REGULATOR
Document Type and Number:
WIPO Patent Application WO/2012/040585
Kind Code:
A3
Abstract:
An adaptive thermal regulator (10) which can regulate the temperature of many heating and/or cooling devices (12) with a resistive or Peltier effect heating and/or cooling element (14) and a sensor (16) with a resistance which varies with temperature. The regulator is connected to a power source (24) and the heating and/or cooling device by mating connectors to allow for independent replacement and the ability to control many different types of devices. The regulator includes a microcontroller (Ul) that runs a program. The microcontroller outputs (01, 02) control a switching circuit for heating/cooling element and an LED indicator for status. Inputs (II, 12, 13) read the state of a momentary-contact switch (SI), the power supply voltage, and the sensor. The temperature setting is increased when the button is pressed and wraps when the highest setting is reached. The power supply voltage is compared to a low threshold value. If the voltage is below this value for a preset period of time, the microcontroller enters a low power state. The microcontroller resumes operation periodically to measure the source voltage. If the voltage is above a high threshold, the microcontroller resumes normal operation.
