Patents by Inventor Pierre Jean Emile Beausseroy

Pierre Jean Emile Beausseroy 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).

  • Method for contactless measuring of vibrations of a rotating body
    Patent number: 6668651
    Abstract: Stationary sensors are used to measure periodically the vibratory motions of portions of a body spinning in front of them, such as blades, and to try to determine their natural frequencies by spectral analyses. The sensors are collected together in several networks of different numbers and the determination includes a comparison of the spectra of the different networks via different operations of selection and rejection of lines. The process appreciably pushes back the limit of unambiguous frequency detection.

  • Method for contactless measuring of vibrations of a rotating body
    Publication number: 20020134158
    Abstract: Stationary sensors (C1 to C8) are used to measure periodically the vibratory motions of portions (2) of a body (3) spinning in front of them, such as blades, and to try to determine their natural frequencies by spectral analyses. According to the invention, the sensors are collected together in several networks of different numbers and the determination consists of a comparison of the spectra of the different networks via different operations of selection and rejection of lines. The process appreciably pushes back the limit of unambiguous frequency detection.
