Abstract: The present invention relates to a method for detecting slippage when gripping an object with a gripper, in which use is made of at least one acceleration sensor (5) on a gripping surface (3) of the gripper (1), a sensor signal from the acceleration sensor (5) is captured during the gripping process and filtered in order to obtain a filtered sensor signal in a first frequency range, and the filtered sensor signal or a value derived therefrom is compared with a threshold value (SW1, SW2) which, when exceeded, constitutes an indication of slippage of the object. In the method, the acceleration sensor (5) is integrated into a rigid main body (2) and the main body (2) is integrated into the gripper (1) using an elastic material (4) so as to be capable of oscillation on the gripping surface (3) such that, in the event of slippage of the object, said main body can be set in oscillation on the gripper (1) only in a plane parallel to the gripping surface (3).

Abstract: A method and system for making available an improved phase signal of a phase sensor on a camshaft of an internal combustion engine immediately after switching on the phase sensor and/or the internal combustion engine are provided. In this context, the phase sensor scans the angle marks of a signal-generating wheel that is connected to the camshaft in a torsionally fixed manner. In addition, a crankshaft sensor scans the angle marks of a signal-generating wheel that is connected to the crankshaft in a torsionally fixed manner.

Abstract: In a method for diagnosis of a sensor in a motor vehicle having an internal combustion engine, during operation of the motor vehicle, an output signal of the sensor is monitored for whether a maximum value of the output signal undershoots a first threshold value and/or a minimum value of the output signal overshoots a second threshold value. In that case a signal is forwarded to a controller that signals to the controller that the sensor, upon restarting of the motor vehicle, might be furnishing incorrect data.

Abstract: A sensor device to record the speed and motion direction of an object, especially rotational speed and direction of a rotating object, based on the magnetoresistive effect, is provided with a magnetic field generator (2, 15) coupled to object (1), which generates a locally and time-defined varying reference magnetic field (H), with two magnetic field sensors (SE1, SE2) made of a magnetoresistive material, which are positioned at a stipulated spacing (&Dgr;y) from each other relative to magnetic field generator (2, 15) so that they are traversed by magnetic field components (H1, H2) of the reference field (H) that are phase shifted relative to each other, in which the phase shift &Dgr;&PHgr; is not equal to an integer multiple of 90°, and with a signal processing circuit (5), which records the magnetoresistive resistance (R_MR1, R_MR2) of the magnetic field sensors (SE1, SE2) dependent on the magnetic field components (H1, H2) in the magnetic field sensors (SE1, SE2) and generates from it electrical signal
