Patents by Inventor Ronald L. Poteet

Ronald L. Poteet 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).

  • Strain gage transducer and process for fabricating same
    Patent number: 4287772
    Abstract: A transducer which includes a metal strain gage material formed on a flexible monocrystalline silicon diaphragm is disclosed. The transducer is fabricated to a large extent with semiconductor processing steps. Gold is diffused into a platinum-tungsten gage material. This allows the gage material to be chemically etched in the presence of other metals to define the active gage resistors. In the presently preferred embodiment, these resistors are formed over thin areas of the diaphragm to provide increased linearity and sensitivity.
    Type: Grant
    Filed: September 4, 1979
    Date of Patent: September 8, 1981
    Assignee: Gulton Industries, Inc.
    Inventors: Carlyle A. Mounteer, Ronald L. Poteet
