Kevin N. Biffert is an inventor associated with Moorhead, Minnesota, and 3M Innovative Properties Company. His patent work includes an optical component designed to direct light through the information holes in a data cartridge’s tape.
Latest Patents
The supplied information identifies one patent for Biffert: “Prism for a Data Cartridge.” The invention describes a substantially hollow prism body with stepped surfaces on the inside of its angled portion. Light passes through a step, reflects from the angled surface, and exits through an adjacent step surface. This design limits reflection to a single surface while reducing the amount of plastic needed. An alternative embodiment uses steps on the internal surface of a mirror instead of a prism.
Career Highlights
Biffert’s listed patent reflects work on optical design for data-cartridge systems. The patent’s stepped geometry is intended to guide light through tape information holes while using less material.
