Rollin Van Alstine 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).

  • Method and apparatus for monitoring integrity of wires or electrical cables
    Patent number: 7068042
    Abstract: An apparatus for monitoring the integrity of a wire is provided, which includes a TDR instrument for generating a pulse waveform for transmission through the wire. The apparatus also includes a function generator for generating an electrical or non-electrical forcing waveform for transmission through the wire. The pulse waveform is transmitted through the wire in combination with the forcing waveform and a detector measures a change in dissipation factor values along the wire.
    Type: Grant
    Filed: July 26, 2005
    Date of Patent: June 27, 2006
    Assignee: CM Technologies Corporation
    Inventors: Gregory Allan, Rollin Van Alstine

  • Method and apparatus for monitoring integrity of wires or electrical cables
    Patent number: 6686746
    Abstract: An apparatus for monitoring integrity of a wire is provided, which includes a TDR instrument for generating a pulse waveform for transmission through the wire. The apparatus also includes a function generator for generating a forcing waveform for transmission through the wire. The pulse waveform is transmitted through the wire by itself, and then in combination with the forcing waveform.
