Adrian Klar 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).

  • Digital circuit for providing a binary signal on the occurrence of a predetermined frequency ratio of two signals
    Patent number: 4509072
    Abstract: The invention provides a digital circuit for generating a binary signal output when a predetermined frequency ratio, v=f1/f2, of two signals F1 and F2 occurs during a selected measuring period. The circuit is particularly adapted for use in a color television receiver to determine the ratio between the chrominance-subcarrier frequency and the horizontal frequency, which ratio is fixed at the transmitting end, both in the PAL system and the NTSC system.
    Type: Grant
    Filed: March 23, 1984
    Date of Patent: April 2, 1985
    Assignee: ITT Industries, Inc.
