Patents by Inventor R. Venkata Ramanan

R. Venkata Ramanan 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: 10495502
    Abstract: A method, system and apparatus is disclosed for auto-tuning a circuit associated with an upstream transducer (UPT) and a circuit associated with a downstream transducer (DNT) for reciprocal operation in an ultrasonic flowmeter. The method includes exchanging signals between the upstream transducer and the downstream transducer; comparing at least one of respective maximum amplitudes of an upstream signal and a downstream signal and respective center frequencies of a Fast Fourier Transform (FFT) of the upstream signal and the downstream signal; and responsive to determining that at least one of the respective maximum amplitudes and the respective center frequencies do not match, correcting the mismatch.
    Type: Grant
    Filed: May 23, 2018
    Date of Patent: December 3, 2019
    Assignee: TEXAS INSTRUMENTS INCORPORATED
    Inventors: R Venkata Ramanan, Anand Dabak, Amardeep Sathyanarayana
