摘要： A sensor arrangement has a plurality of Hall sensor devices, each configured to provide a sensor voltage in response to a magnetic field intensity. A selection unit is configured to forward either of the sensor voltages in response to a selection signal. A transconductance amplifier is configured to generate a sensing current depending on a forwarded sensor voltage. A filter stage has a resistor and a filter capacitor connected in parallel in a switchable manner in response to a first switching signal. The filter stage is configured to generate a filtered voltage across the filter capacitor depending on a sensing current. A capacitive analog-to-digital converter has an input capacitor being connected to the filter capacitor in a switchable manner in response to a second switching signal. The analog-to-digital converter is configured to generate a digital sensor value based on a filtered voltage. The sensor arrangement further has a control circuit which is configured to generate the selection signal and the first and the second switching signals such that for each of the forwarded sensor voltages in a first time segment, the filtered voltage across the filter capacitor is generated, and in a second time segment, the input capacitor is connected to the filter capacitor.

摘要： A control apparatus configured to generate correction values for compensation of disturbance signals of a sensor includes a control loop having an input to receive input values. The control loop includes circuitry configured to receive the input values and configured to produce output values based on the input values, and an evaluation device downstream from the circuitry relative to the input, which is configured to receive the output values and to convert the output values into result values. The apparatus also includes a correction device configured to receive the result values and the input values, to generate correction values based on the result values and the input values, and to provide the result values to the circuitry. The correction device includes a detection device having memory, which stores the input values in the memory based on the result values.

摘要： An arrangement for detecting a movement of a body, in which the body (20′) is mounted in such a way that it can move in at least one direction and in which a magnet (200) is incorporated. Its poles are aligned substantially parallel to a primary plane. A detector system is furthermore provided that comprises at least four magnetic field sensors (10a to 10d) for the detection of a change in the magnetic field when the body (20′) moves. In addition, a further magnetic field sensor (11) is provided for generating a correction signal that depends on the magnetic field. An evaluation unit (20) is used to provide movement information relating to the body (20′) derived from signals from the four magnetic field sensors (10a to 10d) and the minimum of one further magnetic field sensor (11).

摘要： A printer or copier and method for its operation includes two printing units in the paper path. The paper path is formed into two adjoining loops or rings and shunts are provided at intersections to selectively redirect the paper to permit single sided or double sided printing, printing in different colors or re-supplying the paper to a printing unit for a second pass. Papers can be turned over by selective control of the shunts and the conveying directions in the paper paths. Spacing of the sheets if controlled and pre-printed sheets may be selectively brought in to the paper flow.

摘要： In order to control the ejection of sheets from input compartments in a paper output device belonging to a printing or photocopying system, verification occurs as to whether a previously processed sheet has been removed as soon as it has been established that at least one input compartment is almost empty. Ejection of the sheet immediately following according to the order of processing occurs thereafter. These steps are repeated until the input compartment is empty. The printing operation is then stopped.
