Abstract: An autocalibration method includes generating at least one sensor signal in response to measuring a physical quantity; compensating the at least one sensor signal based on at least one compensation parameter to generate at least one compensated sensor signal; generating the at least one compensation parameter based on the at least one sensor signal or the at least one compensated sensor signal; comparing each of the at least one compensation parameter to a respective tolerance range; on a condition that each of the at least one compensation parameter is within its respective tolerance range, transmitting the at least one compensation parameter as at least one validated compensation parameter to be used for compensating the at least one sensor signal; and on a condition that at least one of the at least one compensation parameter is not within its respective tolerance range, generating a fault detection signal.

Abstract: An angle sensor may include a first angle measurement path to determine an angular position based on sensor values from a first set of sensing elements. The angle sensor may include a second angle measurement path to determine the angular position based on sensor values from a second set of sensing elements. A type of the second set of sensing elements is different from a type of the first set of sensing elements. The angle sensor may include a safety path to perform a set of safety checks, the set of safety checks including a first vector length check associated with the first angle measurement path and a second vector length check associated with the second angle measurement path. The angle sensor may include an output component to provide an indication of a result of the set of safety checks.

Abstract: The present disclosure relates to an apparatus for ascertaining a rotation angle of a magnetic field orientation-influencing test object with an axis of rotation in the z-direction. The apparatus may include at least three first magnetic field sensor elements, which are sensitive to magnetic field components in the z-direction. The apparatus may include at least three second magnetic field sensor elements, which are sensitive to magnetic field components in an xy-plane. The apparatus may include a device for ascertaining the rotation angle on the basis of a first combination signal which is based on multiple combinations of measurement signals from the first magnetic field sensor elements and the second magnetic field sensor elements.

Abstract: In some implementations, a sensor may determine a delay latency value associated with an amount of time from completion of a set of sensor tasks to an actual time of reception of a trigger to selectively transmit or sample sensor data. The sensor may calculate a deviation of the delay latency value from a target delay latency. The sensor may transmit a data frame including an indication associated with the deviation of the delay latency value from the target delay latency.

Abstract: A magnetic-field-based angle sensor system includes a stator component and a rotor component rotatable relative thereto, a magnetic field sensor operating in saturation operation and a magnetic field sensor operating in linear operation, wherein the magnetic field sensor operating in saturation operation is configured to determine a rotation angle of the rotor component relative to the stator component, and wherein the magnetic field sensor operating in linear operation is configured to ascertain an external magnetic stray field acting on the angle sensor system. The angle sensor system further includes a control device configured, based on the ascertained external magnetic stray field, to compensate for a stray-field-dependent measurement deviation in the determination of the rotation angle carried out.

Abstract: An integrated circuit (IC) includes an internal clock source configured to generate an internal clock signal; a communication interface configured to receive an external clock signal from an external clock source and a communication frame signal that signals a communication frame during which data communication between the IC and the external clock source is enabled, wherein the external clock signal and the communication frame signal are received in parallel; and a clock monitoring circuit configured to monitor the internal clock signal based on the external clock signal. The clock monitoring circuit is configured to compare the internal clock signal and the external clock signal during the communication frame, and generate a timing error signal if a frequency of the internal clock signal does not satisfy a predetermined threshold relative to a frequency of the external clock signal.

Abstract: Methods and apparatuses for comparing redundant signals in functional safe systems are provided, including methods for mitigating differing signal path delays and for signal weighting of the redundant signals are proposed. An Apparatus includes a first signal path for a first measurement signal of a physical quantity, the first signal path having a first signal propagation delay; a second signal path for a second measurement signal of the physical quantity, the second signal path having a second signal propagation delay different from the first signal propagation delay; a delay compensation circuit configured to compensate for a difference between the first and second signal propagation delays to generate delay-compensated first and second measurement signals; and comparison circuitry configured to compare the delay-compensated first and second measurement signals.
