  • Method and electronic circuit for regenerating an electrical contact
    Patent number: 7109721
    Abstract: A method and an electronic circuit for regenerating an electrical contact are provided in order to remedy the problem of electrical contacts becoming highly resistive over time. Electrical contacts become highly resistive over time, particularly when the contacts are thermally highly stressed and/or exposed to corrosive gases. To remedy this undesired effect and to reestablish the low resistance of the contacts, an electrical regenerating signal is applied to these contacts.
    Type: Grant
    Filed: July 9, 2004
    Date of Patent: September 19, 2006
    Assignee: Robert Bosch GmbH
    Inventors: Helmut Maurer, Eberhard Schnaibel, Lothar Raff, Oliver Hoerrmann
