Klaus Salzwedel 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).

  • Circuit and method for measuring distances
    Patent number: 7061230
    Abstract: A circuit for measuring distances and which has at least two inputs (1, 2), at least one measuring coil (3), and at least one signal source, wherein at least two input signals (epos, eneg) are generated by means of the signal source, and the inputs (1, 2) are activatable by means of the input signals (epos, eneg). The input signals (epos, eneg) are applied, preferably preprocessed, to the inputs of the measuring coil (3). The circuit is designed for use where little space is available for the circuit, with the input signals (epos, eneg) being applied to a preferably timed SC network, which generates a measuring output signal that is dependent on temperature. A corresponding method is also described.

    Date of Patent: June 13, 2006
    Assignee: Micro-Epsilon Messtechnik GmbH & Co. KG
    Inventors: Ulrich Kleine, Falk Roewer, Klaus Salzwedel, Felix Mednikov, Martin Sellen
  • Demodulation circuit
    Patent number: 7012462
    Abstract: A circuit and method for demodulating at least one modulated signal (e), such as a measuring signal of a sensor. The circuit comprises at least one input (1), with the signal (e) being applied to the input (1), and the input is connected to at least one switched-capacitor network which is configured to demodulate the signal. The circuit permits use even in a small available space.
