Latest Patents

One of his latest patents is for a "Battery housing with reverse polarity protection." This invention features a battery housing that includes a contact cage forming a longitudinal cylindrical enclosure with a lateral opening. A leaf spring is incorporated, which has first and second compressible ends. The first end is received by the contact cage through the lateral opening, while a longitudinal insulating cup is included, having opposing cylindrical openings. The second compressible end of the leaf spring is received by the insulating cup through one of the cylindrical openings. This design allows the leaf spring to form a positive terminal in the battery housing, held in position by the contact cage and the insulating cup.

Another significant patent is the "Diopter cell assembly for a binocular viewing system." This optical device is designed to reorient an optical image from a first optical pathway to a second optical pathway. The method of manufacturing this optical device involves providing a housing that defines at least two optical pathways, both aligning with a common aperture in the housing. The common aperture is elliptical in shape, corresponding to the plane of intersection between the two cylindrical pathways. A generally rectangular mirror, larger than the elliptical aperture, is placed over the aperture on the exterior of the housing. This innovative design allows for cost and labor savings compared to prior art.
