Latest Patents

One of Anderson's latest patents is an optical detection device for screening magnetic tape. This device is designed to identify physical defects in magnetic tape by utilizing three light-emitting diodes arranged perpendicular to the tape's direction of travel. The device features two rows of photovoltaic detectors that work in conjunction with the diodes. When the tape is free of defects, light is reflected back to the detectors. However, if a defect is present, the light is scattered, resulting in a reduced amount of light reaching the detectors. Another significant patent is for metallized information carrying discs. This innovation allows for the production of coded information-bearing elements, such as video discs, from multilayered articles. These articles consist of a base with a thermoplastic, radiation-curable resin and an embossable electrically conductive or radiation-reflective layer.
