Title: Royal H Sites: Innovator in Temperature Sensing Technology
Introduction
Royal H Sites is a notable inventor based in Plano, TX (US). He has made significant contributions to the field of temperature sensing technology, holding a total of 3 patents. His innovative approaches have paved the way for advancements in sensor fabrication techniques.
Latest Patents
One of his latest patents is a method of making a temperature sensor. This invention involves a fabrication technique where an insulating substrate supporting a conductive resistive pattern is laser trimmed until the pattern achieves a desired resistance. The back and forth movement of the laser is controlled at an automated laser trimming station. The laser trimmer compares the sensed resistance of the conductive resistance pattern with a sensor pattern that has already been precisely trimmed to a desired resistance and is used as a standard. Another significant patent is a temperature sensing apparatus and method of making the same. This invention features two thick film resistor elements mounted to a substrate, coupled with a thermistor to form a voltage divider. The resistance of the thermistor is determined at a reference temperature, and the thick film resistor elements are precisely trimmed using a laser trimming system to produce a precision voltage divider. To sense temperatures, the voltage divider is energized, and its resistance ratio is sensed utilizing a bridge circuit.
