Title: Innovations by David C Lizon

Introduction

David C Lizon is an accomplished inventor based in Rio Rancho, NM (US). He holds two patents that showcase his innovative contributions to technology. His work primarily focuses on advancements in photocathode devices and liquid level detection systems.

Latest Patents

One of his latest patents is a photocathode device that replenishes its photoemissive coating. This device is designed to replace coating material that desorbs or evaporates during photoemission. A linear actuator system regulates the release of a replenishment material vapor, such as an alkali metal, from a chamber inside the photocathode device to a porous cathode substrate. The replenishment material deposits on the inner surface of a porous membrane and effuses through the membrane to the outer surface, replenishing the photoemissive coating. The rate of replenishment can be adjusted using the linear actuator system to optimize the performance of the photocathode device during photoemission. Alternatively, the system can adjust a plasma discharge gap between a cartridge containing replenishment material and a metal grid, resulting in the ejection of metal ions that replenish the photoemissive coating.

Another significant invention by Lizon is an ultrasonic liquid level monitor. This apparatus and method enable continuous and point level liquid level detection in closed containers or pipes with inaccessible interiors. The invention utilizes frequency domain analysis of the combined storage tank and fluid response to localized ultrasonic energy. This approach requires significantly lower peak excitation voltages compared to traditional pulse-echo ultrasonic techniques.
