    Abstract: A light source is protected by selectively coupling a shunt path in parallel with the light source, such that current is diverted away from the light source and through the shunt path. A detection circuit detects the current flowing in the shunt path when the shunt path is connected in parallel with the light source. A comparator determines whether the current flowing in the shunt path exceeds a predetermined threshold and, if so, prevents or limits the flow of current when the shunt path is disconnected from being in parallel with the light source. In this way, a current detector is provided for monitoring the flow of current in a shunt path, the current detector being configured to disable or limit the flow of current through a light source when a predetermined threshold is reached. This aspect of the invention has the advantage of enabling the current flowing through a light source to be controlled by monitoring the current in the shunt path rather than the path having the light source, thus enabling the maximum current to be controlled without potentially damaging the light source.

    Abstract: A system includes plural sensors to detect at least one of a magnetic field and an electrical field, where each of the plural sensors includes outputs that output sensor signals when a field is detected. Plural signal modulators receive sense signals that correspond to sensor signals from corresponding ones of the plural sensors. Each of the plural signal modulators has first and second control states. In the first control state, each signal modulator outputs sense signals, and, in the second control state, each signal modulator outputs inverted sense signals. A device receives and processes the sense signals or the inverted sense signals.

    Abstract: 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.

    Abstract: A sensor, in particular a Hall sensor, comprising a sensor element (1; 10) which outputs a sensor signal (SS) containing an interference signal (STS). An evaluation device (6; 20) is connected to the sensor element and contains a subtractor (2; 21) which subtracts the interference signal from the sensor signal. The sensor contains a filter device (3), which filters out the interference signal from the sensor signal. The sensor and a related method enable compensation of the interference signal.

    Abstract: A driver apparatus is provided for controlling a light source array comprising at least first and second light sources, the light source array used for illuminating a scan region on a target object, wherein light reflected from said target object is captured by a detector. The driver apparatus comprises a single integrated circuit comprising processing means for processing image data received from the detector, a switching array comprising at least first and second switches for switching the respective first and second light sources, and a current source for controlling the flow of current through the light sources.

The sensor system further comprises a data output (82) and a control circuit (80) with at least one control input (81), allowing to switch the control circuit (80) into at least two different modes. In a normal mode of operation, the signal modulators (30, 31, 32, 33) are configured in such a way that a signal corresponding to the angular position of the diametrically magnetized magnetic source (9) is output to the data output. In an alignment mode of operation, the signal modulators (30, 31, 32, 33) are configured in such a way that a signal corresponding to the average magnetic field strength detected by the sensors (10, 11, 12, 13) is output to the data output (82).
