Abstract: A sensor arrangement is provided. The sensor arrangement includes a rotatable shaft extending along a rotation axis; a magnet module coupled to the rotatable shaft configured to generate a magnetic field; and a sensing element configured to sense a rotating magnetic field caused by the magnet module upon rotation of the rotatable shaft around the rotation axis. The rotatable shaft incudes a bore extending within a shaft end portion along the rotation axis. The magnet module is coupled to at least one face of the bore and configured to generate the magnetic field within the bore. The sensing element has a sensitive spot, the sensitive spot being arranged within the bore and exposed to the rotating magnetic field.

Abstract: A ring magnet for use in determining a rotational angle of a rotatable shaft and configured to be connected to the rotatable shaft for co-rotation with the rotatable shaft around a rotational axis may include a recess in a circumferential surface of the ring magnet, where the recess may be recessed away from the circumferential surface to cause a magnetic sensor to measure a substantially constant ellipticity of a radial component of a magnetic field of the ring magnet and a tangential component of the magnetic field of the ring magnet, when measuring the rotational angle of the rotatable shaft, as the ring magnet moves along the rotational axis of the rotatable shaft.

Abstract: An example device includes a first gradiometer that includes a first set of sensing elements aligned along a first axis, a second gradiometer that includes a second set of sensing elements aligned along a second axis, and a controller. The first set of sensing elements and the second set of sensing elements may be configured to sense a set of magnetic field components that are perpendicular to the rotational axis, wherein the first axis is in a first plane and the second axis is in a second plane, and the first plane and the second plane may be perpendicular to a rotational axis of a rotatable object. The controller may obtain, via the first gradiometer and the second gradiometer, the set of components of the magnetic field. The controller may then determine, based on obtaining the set of components of the magnetic field, the angular position of the rotatable object.

Abstract: A circuit comprise a semiconductor substrate of an integrated circuit, comprising at least two resistors arranged in different orientations in, on or at the semiconductor substrate. The resistance value of the respective one of the resistors is substantially independent of an acting magnetic field. An output signal is determinable on the basis of a comparison of the resistance values of the resistors. Moreover, a circuit comprising a bridge circuit is specified, wherein the bridge circuit comprises at least two MR elements arranged on, at or in a substrate, comprising an extension sensor which provides a signal on the basis of a difference in mechanical extensions in two different directions parallel to a plane in which the two MR elements lie, wherein the circuit is configured to combine an output signal of the bridge circuit by means of the signal.

Abstract: An inductive angle sensor is provided with a stator with an excitation oscillating circuit and a pickup coil arrangement and also with a rotor which is arranged rotatably with respect to the stator and comprises an inductive target arrangement. The excitation oscillating circuit can be energizable with an alternating current, in order to induce an induction current in the target arrangement, and the target arrangement can be designed to generate a magnetic field in reaction to the induction current, which magnetic field in turn generates induction signals in the pickup coil arrangement. The angle sensor further comprises a circuit that is designed to derive an induction strength signal representing the signal strength of the induction signals from the induction signals and to ascertain the spatial clearance between the rotor and the stator on the basis of the induction strength signal, and to generate a corresponding clearance signal.

Abstract: A measurement arrangement includes a first soft magnetic element, a second soft magnetic element, a magnetic element which is mechanically coupled to the first soft magnetic element and is configured to produce a magnetic field, and a sensor arrangement for capturing the magnetic field, which sensor arrangement is arranged in such a manner that a relative movement between the first soft magnetic element and the sensor arrangement results in a change in the magnetic field at the location of the sensor arrangement. The sensor arrangement is configured to determine the change. The sensor arrangement and the magnetic element are arranged between the first soft magnetic element and the second soft magnetic element.
