Introduction

J Douglas Adam is a notable inventor based in Murrysville, Pennsylvania. He has made significant contributions to the field of antenna technology, holding two patents that showcase his innovative approach to electronic systems.

Latest Patents

One of his latest patents is an antenna system using time delays with mercury wetted switches. This invention features an electronically steerable antenna array that incorporates time delay units connected to individual antenna elements. These units are designed to time delay a microwave signal to and from the antenna elements. Each time delay unit utilizes small mercury wetted switches to control signal flow through either a time delay path or a bypass path. The mercury wetted switch itself consists of spaced apart conductors with a high resistivity gate member in between. When a control signal is applied, mercury droplets are drawn to the gate member, establishing an electrical connection between the conductors to close the switch. Upon removal of the control signal, the mercury droplets separate, returning to their initial form and opening the switch.
