Abstract: It is provided an adjustment mechanism, comprising a closure flap for at least partially closing a closure opening on a vehicle, via which, when the closure flap is opened, a connection element for connecting a line and/or a port for topping up a liquid, in particular a fuel, is accessible, a drive for adjusting the closure flap by external force in response to an operator control event, and an electronic control unit which is coupled to the drive and by means of which the drive is activated to open the closure flap in response to an operator control event which is detected in a contactless manner, and, on the other hand, is automatically stopped or reversed in so far as, when the closure flap closes, a possible obstacle is detected in a contactless manner in the adjustment path of the closure flap by means of an anti-pinch mechanism.

Abstract: The present invention relates to a circuit arrangement for detecting a capacitance of a capacitive component and/or a change in the capacitance of a capacitive component, which circuit arrangement comprises, inter alia a monostable flipflop controllable by a control signal and having at least two inputs and one output, wherein a first input of the flipflop is provided for the control signal, and a second input is connected to a capacitive component. The circuit arrangement further comprises a conversion device, which is connected to the output of the monostable flipflop, and an evaluation unit, which is connected to the conversion device in order to evaluate the signal voltage and from this to generate at least one detection value, which indicates the capacitance and/or a change in the capacitance of the capacitive component.

Abstract: A capacitive sensor is configured for detecting an object, in particular for detecting a collision in the case of a movable vehicle part, and an anti-collision apparatus has such a sensor. The sensor has an electrode arrangement with at least one transmitting electrode and at least one or more receiving electrodes. The sensor has a signal generation circuit which is connected upstream of the at least one transmitting electrode. The signal generation circuit generates a transmission signal in the form of a square-wave pulse signal corresponding directly to a pseudo-random bit string.

Abstract: The invention in certain embodiments relates to a control circuit for an electric-motor-operated window lifter (10) of a motor vehicle (1), the control circuit having a first switch (11) for opening a vehicle window (7), a second switch (12) for closing the vehicle window (7), and a control device (15), which, when one of the switches (11, 12) is activated, actuates the window lifter (10) to move the vehicle window (7) in the opening direction or closing direction. The control device (15) monitors the lighting current (ILED) which flows across a lighting element (14) for the switches (11, 12), and generates a control signal (I12), if appropriate, for opening the vehicle window (7) if the lighting current (ILED) exceeds an overcurrent threshold value (IRef) thereby detecting inundation of the vehicle.
