According to a method for operating a Hall sensor assembly, at least two values (I1, I2) of an input signal (I) of a Hall sensor (11) of the Hall sensor assembly (10) having different magnitudes are set and the associated values (V1, V2) of an output signal (V) of the Hall sensor (11) are determined. Furthermore, a residual offset value (k, VOFF) of the output signal (V) is determined according to the values (V1, V2) of the output signal (V) that were determined at the at least two values (I1, I2) of the input signal (I).

A control apparatus configured to compensate for disturbance signals of a sensor includes a control loop having an input to receive input values. The control loop includes a comparison device configured to receive the input values and configured to produce output values following receipt of the input values, and an evaluation device downstream from the comparison device 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 comparison device. The correction device includes a detection device having memory, which stores the input values in the memory based on the result values.
摘要:
A device for conveying sheet-like material between a driven roller and a counter-pressure roller is disclosed. The device also includes opposing guide plates that form a channel for feeding the sheet-like material to the nip between the two rollers. At least one of the rollers includes a channel-like recess into which its associated guide plate extends.

The invention provides for a controller with a control circuit, which contains a feedback path coupled back to the feedback input of the control circuit, a sensor (S) that is arranged in the control circuit and emits a sensor signal at its output, which is converted into a feedback signal and routed back to the feedback input of the control circuit, an error signal generator (F), which generates an error signal and injects it into the control circuit, a detector (D), which monitors a measuring signal of the control circuit that sets the output signal (I2) of the control circuit to a predetermined value as a function of the output signal of the detector. Further, the invention relates to a method for operating this controller, with which an overload operation of the device can be detected.

The invention relates to a method of feeding a sheetlike material (50-54) into a printer. An externally located cover sheet (50-54) is removed from a pile of sheets and conveyed towards a section (a10-a12) of the transport path at a transport speed (V0, V1). The lower limit (v0) of the transport speed is the same as or greater than the transport speed (v0) of the sheets (50-54) in section (a1-a12). Conveyance of the sheet (52,54) is delayed until section (a10-a12) has been reached. Identical predetermined spacing (AS) thus occurs between immediately successive transported sheets (52,54).
摘要:
A method and device for output of single sheets from a printer employs a driven first roller pair having a conveying nip in which a respective single sheet is transported and deflected from an approximately vertically proceeding conveying path into an approximately horizontal conveying path. A separation element that suppresses a continued conveying of the respective single sheet on a circumferential surface of a lower roller of the roller pair is arranged in a proximity of the circumferential surface of the lower roller. An edge sensor is arranged preceding the roller as viewed in a conveying direction for determining whether single sheets have pushed on top of one another. A discharge brush electrically discharges one side of the single sheet arranged in the conveying path following the roller pair. A deflection device deflects the single sheet emerging from the conveying nip into a substantially horizontal attitude shortly before the conveying nip as viewed in a direction of the conveying path. The discharge brush is mounted to the end of the deflection device.

A controller includes a control circuit. The control circuit includes a forward path that includes an input and an output, a feedback path coupled to the output and to the input, and a sensor that is between the input and the output. The sensor generates a sensor signal based on an input signal applied to the input. The forward path generates an output signal based on the sensor signal. The output signal is sent along the feedback path to the input of the forward path. The controller also includes a detector that obtains an intermediate signal from the forward path between the input and the output. The detector generates a control signal using the intermediate signal. The forward path includes a control device that limits the output signal to a predetermined value. The detector controls the control device using the control signal.
