Title: Richard E. Mullen: Innovator in Liquid Level Detection Technology
Introduction
Richard E. Mullen is a notable inventor based in Tustin, California. He has made significant contributions to the field of liquid level detection technology. His innovative approach has led to the development of a unique circuit that enhances safety in underwater lighting applications.
Latest Patents
Mullen holds a patent for a "Liquid level detection circuit for control of liquid level responsive." This invention features a liquid level presence detection circuit that includes a selectively gatable TRIAC connected in series with a load. The circuit is triggered into conduction by twin sensitive-gate SCRs, which are connected anode-to-cathode. The gates of the SCRs receive gating current from voltage divider circuits, responding to the presence of a conductive liquid bridging two spaced apart contacts of a liquid presence detecting probe. This technology is particularly useful in wet-niche lamp assemblies that provide underwater illumination in swimming pools. The circuit interrupts the flow of electrical energy to the lamp when the surrounding liquid level falls below a predetermined level, preventing over-temperature operation and potential damage. It resumes energy flow when the liquid level increases to a safe level, ensuring adequate cooling.
