Title: The Innovative Contributions of Irving Liberman
Introduction
Irving Liberman is a notable inventor based in Pittsburgh, PA, who has made significant contributions to the field of physics and engineering. With a total of six patents to his name, he has developed innovative technologies that enhance the functionality of atomic clocks and frequency standards.
Latest Patents
One of Liberman's latest patents is the "Physics package apparatus for an atomic clock." This invention features a cell structure that includes a central plate sandwiched between top and bottom plates. The central plate has a central interior aperture that, along with the top and bottom plates, forms an internal cavity for the containment of an active vapor. Additionally, the central plate includes a reservoir for holding a source of the active vapor, with a channel connecting the reservoir to the internal cavity. A heater is positioned on the underside of the bottom plate to heat the vapor. The plates are batch processed on respective wafers, which are subsequently joined together and cut into individual cell structures.
Another significant invention is the "Miniature atomic frequency standard." This device utilizes a tubular vapor cell that extends transversely through a TE.sub.210 microwave cavity. In one embodiment, the vapor cell is heated directly by electric heaters secured to the ends of the tubular vapor cell, which extend outside the microwave cavity. The vapor cell is insulated by thermal insulation inside the microwave cavity and between the microwave cavity and a magnetic shield. In another embodiment, the entire microwave cavity is heated, eliminating the need for thermal insulation inside the cavity, allowing for a smaller design. A laser diode outside the magnetic shield transmits light to the vapor cell through optic fiber, and a photodiode with an integral lens serves as the detector.
