Abstract: A current sensor arrangement includes a first conductor structure extending in a first direction and configured to carry a first current along the first direction; a second conductor structure extending in a second direction perpendicular to the first direction and configured to carry a second current along the second direction; and a magnetic field sensor arranged between the first conductor structure and the second conductor structure and configured to receive a first magnetic field produced by the first current and a second magnetic field produced by the second current. The first conductor structure and the second conductor structure overlap with the magnetic field sensor in a third direction that is perpendicular to the first and second directions. The magnetic field sensor includes a first sensor element sensitive to the first magnetic field and a second sensor element sensitive to the second magnetic field.

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.
