  • Device and method for checking an assembly wrench
    Patent number: 9778133
    Abstract: A method for checking an assembly wrench, having an integrated angular measuring device, includes: fixing the assembly wrench in a rotatable fixing device; activating the angular measuring device integrated in the assembly wrench; rotating the fixing device by at least one specified angle; reading off the angle of rotation measured by the angular measuring device integrated in assembly wrench; and comparing the angle of rotation measured by the angular measuring device integrated in the assembly wrench to the specified angle, by which the fixing device has been rotated.
    Type: Grant

  • Device and method for checking an assembly wrench
    Patent number: 9726568
    Abstract: A device for testing an assembly wrench has a tool holder, and a drive element includes a fixing device which is configured to fix the tool holder. A receiving device is configured to receive and fix the drive element and may be pivoted over an arc, and at least two stops are disposed along the arc and are configured to arrest the receiving device in one defined position at a time.

  • Method and diagnostic device for diagnosing a heatable exhaust gas sensor of an internal combustion engine
    Patent number: 9062623
    Abstract: A method is described for diagnosing a heatable exhaust gas sensor of an internal combustion engine, in which a predefined chronologically varying or constant voltage or a predefined chronologically varying or constant current is generated with the aid of a voltage source, the voltage or the current is applied to terminals of the exhaust gas sensor, a current or applied voltage, which flows through the voltage source when the voltage or the current is applied, is detected, and the current or the voltage is analyzed to diagnose the exhaust gas sensor.
