Abstract: A protective arrangement for a motor vehicle for protecting a high-voltage battery of the motor vehicle from the penetration of liquid. The protective arrangement has an electrical component connected to the high-voltage battery via a cable, which component has a drainage device with a drain opening and a closure, by which the drain opening can be released depending on the pressure, a cooling circuit with a circuit component arranged on the component housing, through which component a coolant can flow, and with a pump to pump coolant through the circuit component, and a control device, which is designed to control the pump depending on detection of at least a probable penetration of coolant into the component housing in such a way that an increased pump power is at least temporarily provided by the same if the pump is not yet in a state of maximum pump performance.

Abstract: Apparatus for the detection of print marks with a sensor arrangement which has at least one contrast sensor, which for generation of a cyclical sensor signal is disposed above the area of printed material containing the print mark which is passed below the contrast sensor, said apparatus also having a signal conditioning unit. The signal conditioning unit has at least one filter unit with a first filter for determination of the first derivation of the sensor signal, and on the basis of an evaluation of at least the first derivation of the sensor signal the filter unit generates at least one output value which is representative of print marks.

Abstract: A method for detection of print marks by evaluation of a cyclical sensor signal (S) from at least one contrast sensor, which senses an area of printed material containing a print mark that passes below the contrast sensor. The method includes forming a first derivation (S?) of the cyclical sensor signal (S); determining a first edge region in a region where the first derivation (S?) falls below a lower threshold value; determining a second edge region in a region where the first derivation (S?) exceeds an upper threshold value; determining characteristic values for the first edge region and the second edge region; associating a print mark detection between the first edge region and the second edge region based on the determined characteristic values; and generating at least one output value which is representative of the print marks.

Abstract: Apparatus for the detection of print marks (2, 2?) with a sensor arrangement (4) which has at least one contrast sensor (1, 1?), which for generation of a cyclical sensor signal (S) is disposed above the area of printed material (8) containing the print mark (2) which is passed below the contrast sensor (1, 1?), said apparatus also having a signal conditioning unit (5). The signal conditioning unit (5) has at least one filter unit (11) with a first filter (F1) for determination of the first derivation (S?) of the sensor signal (S), and on the basis of an evaluation of at least the first derivation (S?) of the sensor signal (S) the filter unit (11) generates at least one output value (Ox) which is representative of print marks (2, 2?).
