Patents by Inventor Konrad M. Dinter

Konrad M. Dinter 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).

  • Voltage control oscillator having frequency control circuit with improved memory
    Patent number: 4358740
    Abstract: A VCO control circuit features a first exclusive-OR gate to the inputs of which are applied signals derived from the VCO to provide an output signal that has a 90.degree. phase shift with respect to a reference signal. A second exclusive-OR gate serves as a phase detector for the output and reference signals and provides, after filtering, a frequency control voltage for the VCO. The control voltage has about the same amplitude regardless of the presence or absence of the reference signal.

  • Digital tracking system
    Patent number: 4335408
    Abstract: A tracking system for a VTR features digital circuitry, such as a counter, for immunity to component tolerances and power supply voltage shifts. It also allows holding a constant control voltage when desired. A tachometer input signal need not be converted to an analog one, which eliminates A/D converter failure problems.
