Patents by Inventor Philippe Patrick Calmettes

Philippe Patrick Calmettes 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: 10401171
    Abstract: A system is provided that includes a mechanical resonator, and an analog circuit coupled to the mechanical resonator. The analog circuit is arranged to receive a mechanical resonator measurement signal having a quadrature error from the mechanical resonator, and to extract a quadrature error signal from the mechanical resonator measurement signal using a quadrature clock. A digital quadrature controller is coupled to the analog circuit and is arranged to generate a quadrature error compensation signal from the extracted quadrature error signal and apply the quadrature error compensation signal to the mechanical resonator or the mechanical resonator measurement signal to reduce quadrature error in the mechanical resonator measurement signal error.
    Type: Grant

  • Patent number: 10330474
    Abstract: MEMS gyroscopes are often integrated in modern electronic products for measuring orientation or rotation in those products. However, these MEMS gyroscopes are often inaccurate. The invention provides a compensation circuit to compensate for errors causing a distortion of a measured Coriolis force. The compensation circuit demodulates an input signal provided by the MEMS gyroscope to produce a quadrature signal indicative of the quadrature error and provides a compensation signal to the MEMS gyroscope for actively compensating the quadrature error.
