Patents by Inventor Sam Scheinman

Sam Scheinman 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).

  • Non-destructive testing apparatus for the detection of graphitization of iron
    Patent number: 8154279
    Abstract: A sensor measures the interaction of an applied magnetic field to an iron sample surface to determine whether the sample surface has been graphitized. The sensor measures the magnetic force resulting from the interaction or the magnetic flux density to determine the content of magnetic material in localized regions of the sample surface. The sensor includes a cantilever beam with a strain gauge for measuring magnetic force. Alternatively, the sensor includes a magnetic flux density sensor to measure magnetic flux density.
    Type: Grant
