ABSTRACT:
The air caloric stimulation system provides an adjustable air system with accurate and automatic control of the delivery and temperature of air. A thermal electric device utilizing the Peltier effect generates or absorbs heat depending on the difference between the temperature of the air at the outlet and the "set" or desired temperature of the air at the outlet. Further, the Peltier units are aided in controlling the temperature of the air using a radiator system in conjunction with a liquid circulating system. The current to the Peltier units are controlled using unique proportional phase controlled signals. Safety circuitry prevents the air or liquid from overheating.
