A device comprises a magnet and an angle sensor, wherein the angle sensor is configured to detect a rotation angle of the magnet. The device also contains a rotation counter, wherein the rotation counter is configured to record a number of rotations of the magnet. The angle sensor and the rotation counter are implemented in physically separate components.

Devices having a turn counter and associated production methods

A sensor device includes a first sensor element that generates a first sensor signal based on a varying magnetic field; a second sensor element that generates a second sensor signal based on the varying magnetic field; a signal processing circuit configured to generate a first pulsed signal based on the first sensor signal and generate a second pulsed signal based on the second sensor signal; a fault detector that detects a fault and generates an error signal indicating the fault; and an output generator that receives the error signal based on a first condition that the fault detector detects the fault, and simultaneously outputs a first output signal and a second output signal. In response to the first condition being satisfied, the output generator maintains the first output signal in a steady state and outputs the second pulsed signal as the second output signal.

Sensor device, control system and method of communication between a sensor device and a control system. Sensor devices, control systems and methods for communication between sensor devices and control systems are provided. In these, sensor data are transmitted via first interfaces and redundant sensor data and/or other data are transmitted via second interfaces.

Sensor device, control system and method of communication between a sensor device and a control system

A magnetic field sensor for detecting a direction of a magnetic field comprises an xMR sensor designed to produce an xMR sine signal and an xMR cosine signal based on the magnetic field, and an AMR sensor designed to produce an AMR sine signal and/or an AMR cosine signal based on the magnetic field. A processing circuit is designed to determine the direction of the magnetic field using the xMR sine signal, the xMR cosine signal, a first phase difference between the xMR sine signal and the AMR sine signal or the AMR cosine signal, and a second phase difference between the xMR cosine signal and the AMR sine signal or the AMR cosine signal.

Drift-compensated detection of a direction of a magnetic field

A magnetic angle sensor including a first Wheatstone bridge circuit having a plurality of first magnetoresistive elements; and a second Wheatstone bridge circuit having a plurality of second magnetoresistive elements, wherein the plurality of second magnetoresistive elements have diversity with respect to the plurality of first magnetoresistive elements.

Diversity in magnetic sensors

A system including a sensor circuit and comparison circuitry. The sensor circuit is configured to provide a sensed signal. The comparison circuitry is configured to receive an input signal that corresponds to the sensed signal. The comparison circuitry provides output signals that switch state at different levels of the input signal.

Sensor system including multiple comparators

A magnetic angle sensor may include a first bridge circuit. The first bridge circuit may include a first half-bridge to generate a first signal indicative of a first angular component of a direction of a magnetic field. The first bridge circuit may include a second half-bridge to generate a second signal indicative of a second angular component of the direction of the magnetic field. The second angular component may be linearly independent from the first angular component.
