David J Roscoe is a notable inventor based in California, recognized for his contributions to antenna technology and cargo detection systems. With a total of 3 patents, Roscoe has made significant advancements in the field, particularly in the design and functionality of antennas for satellite communication.

Latest Patents

One of Roscoe's latest innovations is the Dual Role Antenna Assembly. This assembly is designed for use with both Geostationary (GEO) and Low/Medium Earth Orbit (LEO/MEO) satellites. It features at least two curled inverted-F antennas that are substantially omnidirectional and mounted on a ground plane. These antennas have asymmetrical gain patterns that favor specific sectors, and they are oriented to ensure that the favored sectors of the different antennas face different directions. A controller is employed to select the appropriate antenna for connection to an RF front-end based on predetermined performance criteria.

Another significant patent is the Optical Cargo Detection system. This innovative detector is designed to identify cargo within a container. It consists of a controller block, a transmitter that emits light into the field of view, a receiver that captures reflected light, and a threshold comparator that assesses whether the received light meets a specific threshold for cargo detection. The receiver is equipped with a DC block to eliminate the effects of ambient light. This detector performs multiple detection cycles and averages the results, which can then be compared with previously stored conditions of cargo presence or absence to enhance detection accuracy.
