ABSTRACT:
An array of Peltier-effect thermoelectric tiles are controlled by a microprocessor so as to produce a repeatable series of temperature patterns or sequences on the skin adjacent to the area of pain. The series can be modified by selecting between one and m different pre-programmed thermal patterns or sequences by the appropriate setting of a m-toggle switch bank. The hot intensity, cold intensity and time delay between sequences can also be selected. The period between temperature changes is greater than one minute. A variety of different pain soothing sequences can be generated including checkerboard patterns, hot and cold waves, alternating left and right side temperature changes, etc.
