Gerald W. Scheck has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Transparent digitizer platen
    Patent number: 4353952
    Abstract: A metallic foil is laminated to a transparent substrate with a photopolymerizable adhesive. An outer layer of photoresist is used in etching a pattern in the foil. The etched foil itself is then used as a resist in the complete removal of the uncovered portions of the adhesive, leaving the transparency of the revealed substrate material totally unimpaired. Finally, the remaining adhesive is hardened by polymerization resulting from exposure to ultraviolet light passed through the substrate from the unlaminated side.
    Type: Grant
    Filed: April 27, 1981
    Date of Patent: October 12, 1982
    Assignee: Hewlett-Packard Company
    Inventors: Lawrence E. Brown, James L. Bauer, Gerald W. Scheck
