Abstract: A sensor system may include an object, a magnet, and a magnetic sensor. The magnet may be connected to the object such that a center of the magnet is offset from an axis of the object. The magnetic sensor may include a first three-dimensional (3D) sensing pixel and a second 3D sensing pixel. The magnetic sensor may be arranged such that the first 3D sensing pixel and the second 3D sensing pixel are at different distances from a tilt point of the object. The magnetic sensor may be arranged such that the first 3D sensing pixel and the second 3D sensing pixel are at different distances from the center of the magnet.

Abstract: The innovative concept described herein relates to a magnetic-field-based current measuring device. The latter includes, inter alia, an at least two-dimensionally measuring magnetic field sensor mounted at a node at which a first, a second and a third electrical conductor, each coming from different directions, are brought together. The magnetic field sensor is configured to determine in each case a magnitude and/or a direction of the magnetic fields which are respectively generated in the first, second and third electrical conductors and meet at the node, and to derive, on the basis thereof, information about a magnitude and/or a direction of the individual electric currents flowing at the node. The innovative concept described herein additionally relates to a corresponding method for magnetic-field-based measurement of electric currents using a magnetic-field-based current measuring device.

Abstract: A method of determining a position of a first object includes receiving a first component and a second component of a vector field jointly generated by the first object and by a second object. The method further includes using the second component of the vector field to provide a compensation quantity indicating a contribution of the second object to the first component of the vector field. Further, the method includes determining the position of the first object using the first component of the vector field and the compensation quantity.

Abstract: A magnetic sensor device includes a three-dimensional (3D) magnetic sensor and a magnet that produces a magnetic field. The 3D magnetic sensor is arranged within the magnetic field and is configured to measure three different magnetic field components of the magnetic field and generate sensor signals in response to the measured three different magnetic field components. The magnet is arranged in a default spatial position in an absence of any applied spatial force, where the magnet is configured to rotate about a rotation axis based on an applied rotational force. The magnetic field varies inhomogeneously with regards to at least one of the three magnetic field components upon rotation of the magnet about the rotation axis.
