Patents by Inventor William Steichen

William Steichen 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).

  • Hybrid resonant structure to verify parameters of a tire
    Patent number: 7916012
    Abstract: Control of running conditions, and particularly physical parameters of tires are recommended to increase automobile safety. A sensor according to the invention is used to determine various factors such as the temperature or pressure of tires. The sensor is a hybrid resonant passive structure that may be integrated in the vehicle ground connection, and particularly in the rubber of the tire when it is manufactured.
    Type: Grant
    Filed: July 28, 2006
    Date of Patent: March 29, 2011
    Assignee: Michelin Recherche Et Technique S.A.
    Inventors: Lionel Fagot-Revurat, Sylvain Ballandras, Jérémy Masson, William Steichen
  • Hybrid resonant structure
    Patent number: 7609132
    Abstract: A bulk wave acoustic resonant structure which is in accordance with the invention allows the difficulties encountered at high frequency, the impossibility of working at low frequency on simple structures and the absence of an adequate coupling level to be overcome. The invention therefore proposes the use of an additional layer of material which covers the upper electrode of a piezoelectric transducer in order to localize the position of maximum intensity of the dynamic stress close to the centre of the piezoelectric layer through the effect of propagation. The structure that is in accordance with the invention may be associated with Bragg mirrors and various uses are presented.
