Patents by Inventor Frank-Jurgen Stuetzler

Frank-Jurgen Stuetzler 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).

  • Optical deformation sensor with operational testing by different wavelengths, for side crashers
    Patent number: 6864477
    Abstract: The deformation sensor does not require a supplementary sensor to check functionality. This deformation sensor includes an optical transmission medium, multiple transmission elements, which couple the light of various wavelengths into the transmission medium, and multiple reception elements, which selectively couple the transmitted light out of the transmission medium according to wavelength. An evaluation unit detects deviations between the output signals of the reception elements and signals a malfunction of the sensor if the deviations exceed a preset measure.

  • Optical deformation sensor with operational testing by different wavelenghts, for side crashes
    Publication number: 20020162952
    Abstract: A deformation sensor is described which does not require a supplementary sensor to check functionality. This deformation sensor includes an optical transmission medium (ÜM1, ÜM2), multiple transmission elements (S1, S2), which couple the light of various wavelengths (&lgr;1, &lgr;2) into the transmission medium (ÜM1, ÜM2), and multiple reception elements (E1, E2), which selectively couple the transmitted light out of the transmission medium (ÜM1, ÜM2) according to wavelength. An evaluation unit (AW) detects deviations between the output signals (a1, a2) of the reception elements (E1, E2) and signals a malfunction of the sensor if the deviations exceed a preset measure.
