Latest Patents

One of Evans' latest patents is titled "Switch matrix including both B switching elements and crossbar switch." This invention presents a modified rearrangeable switch matrix that integrates both beta switching elements and crossbar switch matrices into a single configuration. The beta switching elements are utilized at both the input and output, while at least one crossbar switch matrix is positioned in the middle to manage inputs and outputs effectively.

Another significant patent is "Multiple spot-beam systems for satellite communications." This invention outlines a three-stage on-board satellite switching process. The outer stage manages switching on the up-link side to route received signals to either demodulators or frequency translators. The first inner stage, preferably a baseband switch and processor, is responsible for routing and processing the outputs of the demodulators. The second inner stage, which may consist of a microwave switch matrix, routes the outputs of the frequency translators. The down-link side also features an outer stage for assembling and routing the down-link spot beams. This patent also discusses a general-purpose modified rearrangeable switch matrix.
