Abstract: An absolute position measurement system includes a multipole magnet comprising alternating magnetic poles extending along a multipole extension direction, the alternating magnetic poles generating a magnetic field. A magnetic sensor includes a first sensor element arrangement configured to generate a first signal in response to a first magnetic field component and a second sensor element arrangement configured to generate a second signal in response to a second magnetic field component. The absolute position measurement system is configured, as a position of the magnetic sensor relative to the multipole magnet changes, to generate a first oscillating sensor signal with decreasing first signal amplitude and to generate a second oscillating sensor signal with decreasing second signal amplitude based on the first and second signals. A processing circuit is configured to calculate an absolute position of the magnetic sensor based on the first oscillating sensor signal and the second oscillating sensor signal.

Abstract: In some implementations, an angle sensor may receive a first x-component value and a first y-component value from a first set sensing elements and a second x-component value and a second y-component value from a second set of angle sensing elements. The angle sensor may perform a safety check including determining a first range of angles associated with a target object based on a relationship between a magnitude of the first x-component value and a magnitude of the first y-component value; determining a second range of angles associated with the target object based on a relationship between a magnitude of the second x-component value and a magnitude of the second y-component value; and determining whether the second range of angles is a subset of the first range of angles. The angle sensor may output an indication of a result of the safety check.

Abstract: A sensor module includes at least one sensor configured to generate sensor information and processing circuitry configured to generate a sensor signal based on the sensor information. The sensor signal includes a sync frame, including two sync signal edges defining the sync frame and indicating a pre-determined synchronization time interval, and the sensor signal further includes a plurality of data signal portions, including at least one data signal portion transmitted within the sync frame. The at least one data signal portion is provided within the sync frame located between the two sync signal edges, wherein each of the at least one data signal portion is defined by at least one data signal edge interposed in the sensor signal between the two sync signal edges.

Abstract: Magnetic field sensor devices, corresponding systems and corresponding methods are discussed where a plurality of magnetic field sensors senses a magnetic field. An evaluation circuit generates a first signal component associated with a periodicity of a magnetic field, and a second signal component at least for periods of the magnetic field exceeding a threshold period length, the second signal component having a resolution smaller than the first signal component.

Abstract: A receiver may receive a pulse width encoded signal. The receiver may determine a position of a transition of a pulse of the pulse width encoded signal by oversampling the pulse width encoded signal with respect to a quantization function. The receiver may determine that the position of the transition deviates from an expected position according to the quantization function by more than a predetermined range. The receiver may generate a signal, indicating an unexpected event, based on determining that the position of the transition deviates from the expected position. The receiver may detect an error in a message corresponding to the pulse width encoded signal based on a check value identified from the pulse width encoded signal. The receiver may adjust, based on the signal indicating the unexpected event, a value, corresponding to the position of the transition, to cause the error in the message to be corrected.

Abstract: A driving safety system for a motor vehicle with at least one wheel speed sensor is disclosed, which is configured to determine the actual wheel speed on a wheel, and a driving safety control unit configured to receive a wheel speed signal generated by the wheel speed sensor, where the wheel speed signal represents a determined actual wheel speed. The wheel speed signal is transmitted via an unprotected transmission channel between the wheel speed sensor and the driving safety control unit. The driving safety control unit is configured to receive a travel signal that correlates with the actual vehicle speed and to compare the travel signal with the wheel speed signal to check the wheel speed signal for plausibility. The movement signal is transmitted to the driving safety control unit via a safe transmission channel.
