Title: The Innovative Contributions of Michael L. Hoopes

Introduction

Michael L. Hoopes is a notable inventor based in Novato, California. He holds a total of 4 patents that showcase his expertise in developing advanced electrical protection devices. His work has significantly contributed to the field of surge protection technology.

Latest Patents

One of his latest inventions is the Controlled Convection Thermal Disconnector. This surge protection device employs a controlled convection thermal disconnector, where a surge protective component, such as a metal oxide varistor, and a thermally responsive device, like a thermal cut-off, are placed in separate, cross-ventilated chambers. An internal vent is strategically positioned to prevent line-of-sight between the surge protective component and the mechanized portion of the thermally responsive device. This design protects the thermally responsive device from hot emissions generated by the surge protective component. Additionally, an output vent is formed between the thermally responsive device and the exterior atmosphere to promote forced convective heat transfer during thermal runaway conditions.

Another significant patent is the Unsafe Voltage Shutoff Control. This circuit and device protect connected equipment from a wide range of unsafe over-voltage and under-voltage conditions by disconnecting the line voltage before surge protection components, typically MOVs, are damaged by sustained surges. The device avoids nuisance tripping by discriminating between surges that can be managed by the MOVs and those that cannot. Furthermore, the circuit features deliberate hysteresis, ensuring that the turn-on voltage is about 10 to 20 volts lower than the shut-off threshold, thus preventing repeated cycling between on and off states during slight fluctuations in line voltage.
