Latest Patents

Keith Ronald Rosenthal holds a patent for a "Cryogenic electronic assembly." This invention involves a number of electronic modules mounted on a cold finger within a sealed housing that is evacuated. To minimize heat transfer by conduction, gaps are provided in the dielectric substrates carrying the input and output transmission lines, which create signal paths between the modules and electrical connectors on the exterior sidewalls of the housing. The gaps are bridged by thin conductive wires, providing low electrical but high thermal impedance. Additionally, multiple module assemblies can be stacked on a single cold finger. To facilitate adjustments under actual operating conditions, a cover with spring-loaded screwdrivers extends through vacuum-tight seals, allowing for alignment with adjustable components of the modules. The springs urge the screwdrivers out of engagement when no adjustment is being made, minimizing heat transfer.
