Title: The Innovations of Theodore D. Michaelis

Introduction

Theodore D. Michaelis is a notable inventor based in Medford, NJ (US). He has made significant contributions to the field of cooling systems, holding a total of 7 patents. His work primarily focuses on advanced control systems and thermoelectric cooling technologies.

Latest Patents

One of his latest patents is titled "Compensation circuit for control system providing pulse width modulated." This invention describes a closed-loop, temperature-controlled cooling system that utilizes a Stirling cycle refrigerator driven by a DC motor. The motor's excitation is derived from pulse width modulation, allowing for precise temperature control. The system includes a temperature-sensitive bridge circuit that generates an error voltage in response to temperature variations, affecting the modulator duty cycle. This innovation ensures that the cooling amount is directly related to the average voltage applied to the motor.

Another significant patent by Michaelis is the "Thermoelectric cooling system and method." This invention regulates the flow of electric current into a thermoelectric cooler to maintain a desired cold-side temperature without directly measuring the temperature of the device affixed to the cooler's cold side. The system periodically interrupts the current flowing to the cooler and measures the open circuit voltage across the cooler, induced by the temperature difference between the hot and cold sides. This measurement, combined with the hot side temperature, allows for accurate cold side temperature regulation.
