Title: M DuChesne Courtney: Innovator in Sensor Technology and Vacuum FETs
Introduction
M DuChesne Courtney is a notable inventor based in Mission Hills, CA (US). He holds 2 patents that showcase his contributions to sensor technology and vacuum field effect transistors (FETs). His work has significant implications in various industries, particularly in monitoring gas levels and enhancing electronic functionalities.
Latest Patents
One of Courtney's latest patents is the Carbon monoxide/hydrocarbon thin film sensor. This innovative ceramic sensor comprises a thin film of Cu.sub.x Mn.sub.3-x O.sub.4, which quantitatively measures the partial pressure of CO and hydrocarbon gases in a flowing system. The sensor is specifically designed to be negligibly affected by common automobile exhaust vapors such as NO and H.sub.2 O, operating effectively within a temperature range of about 250.degree. to 450.degree. C. This technology has applications in monitoring CO and hydrocarbon levels in laboratories, mines, and industrial smoke stacks, with capabilities extending to environments up to about 700.degree. C.
Another significant invention is the Split collector vacuum field effect transistor. This vacuum FET is engineered to perform higher-level functions such as logic AND, EXCLUSIVE OR (NOR), demultiplexing, or frequency multiplication with a single device. The design involves dividing the collector of the vacuum FET into multiple segments and utilizing steering electrodes above the emitter to direct the field emission current to various collector segments. The configuration of the applied signals and the collector pattern determines the higher-order function performed by the device.
