Matthew J. Klueppel 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).

  • Patent number: 6359476
    Abstract: A frequency correction circuit includes a temperature sensor (100) disposed to measure temperature and produce temperature signals representing sensed temperatures. A data supplier (110) stores information items, receives digital input signals representing and produces a digital output information signal representing an item selected in accordance with the digital input signal. A control circuit (120) receives the temperature signals and receives the digital output information signal. The control circuit (120) produces control signals based on the temperature signals. A clock circuit (150) is disposed to generate a reference frequency signal. A digital synthesizer (130) receives the reference frequency signal and the control signals. The digital synthesizer produces an output frequency signal as directed by the control signals received from the control circuit (120).
    Type: Grant
