Patents by Inventor Willi Wimmer

Willi Wimmer 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).

  • Position encoder comprising a plastic element
    Patent number: 8629676
    Abstract: Disclosed is a position sensor, in particular a rotor position sensor, comprising a base. A track that is provided with a conducting coating is formed within the surface of the base relevant for evaluating signals. Since the track is formed within the base, the desired position-dependent modulation of the eddy current behavior is obtained by design measures, resulting in low manufacturing tolerance and reduced production costs.
    Type: Grant
    Filed: September 10, 2008
    Date of Patent: January 14, 2014
    Assignee: Sumida Components & Modules GmbH
    Inventors: Rudolf Kronawitter, Willi Wimmer

  • Moisture-detection device
    Patent number: 6981405
    Abstract: A device for determining moisture has an LC-oscillating circuit as a transducer and an oscillator for exciting the oscillating circuit. Further, the device for determining moisture has a tuning device for frequency-wise tuning the oscillator and a measuring and evaluation circuit to determine an attenuation condition of the oscillator and to provide a signal that is proportional to a degree of moisture at the transducer. The transducer and the oscillator are coupled in a contact-free manner.
