Benjamin Thiel 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).

  • Combustion-chamber pressure sensor having a metallic diaphragm containing a piezoresistive, thin metallic layer
    Patent number: 7159448
    Abstract: A pressure sensor for measuring the pressure in a space acted upon by high pressure. The signals detected by the pressure sensor are supplied to evaluation electronics. A sensor diaphragm is accommodated on the end of the pressure sensor pointing towards the space acted upon by high pressure. The sensor diaphragm takes the form of a steel diaphragm, to whose back side a thin, metallic layer accommodating piezoresistive measuring elements is applied. The thin, metallic layer is contacted by transmission elements and connected to the evaluation electronics.

  • Pressure sensor element having an integrated sealing surface
    Publication number: 20050126297
    Abstract: The present invention relates to a sensor element for detecting pressures or forces. The sensor element (10) includes a sensor diaphragm (13), on the diaphragm outer side (20) of which piezoresistive measuring elements (8) are located. The sensor diaphragm (13) of the sensor element (10) is diametrically opposed to a sealing surface (15, 16) for sealing off the sensor element (10) from a housing. A force introduction region (23, 24) for introducing a force which produces a seal is mechanically decoupled from the sensor diaphragm (13) of the sensor element (10).
