Title: Bruce E Metz: Innovator in Heating Technology
Introduction
Bruce E Metz is a notable inventor based in Wilmington, DE (US), recognized for his contributions to heating technology. He holds a total of 9 patents, showcasing his innovative approach to enhancing heating units and temperature sensing mechanisms.
Latest Patents
Among his latest patents is a "Heating unit with temperature sensor." This invention features a bridge with an arm housing a heating element and a circuit designed to direct a sensing current through the heating element. The circuit reduces the duty cycle of the sensing current, which in turn lowers the average sensing current while allowing for higher peak sensing currents. Various embodiments of this invention utilize zener diodes and electronic logic to determine the start and stop points of the sensing current pulses. This technology enables the sensing of heating elements with very small temperature coefficients and ensures that the sensing current remains relatively stable despite variations in supply voltage.
Another significant patent is the "Heating unit incorporating a temperature sensor." This control device integrates both a heating element and a temperature sensor, structured as a Wheatstone bridge that applies sensing current to the heating element. When the bridge is unbalanced, it can apply heating current to the element. The design includes features for reducing electrical spikes and allows for remote control of the set point, enhancing its usability and accuracy.
