  • Patent number: 11402439
    Abstract: In a method for calibrating the sensitivity of a monoaxial or multiaxial magnetic field sensor, the magnetic field sensor is exposed consecutively to at least three magnetic fields having different magnetic field vectors which may be freely orientated in space so that they span an oblique coordinate system. The magnetic fields are measured with the magnetic field sensor in order to obtain a sensitivity vector in the oblique coordinate system of the magnetic field vectors for each sensor axis. The sensitivity vectors are transformed into an orthogonal coordinate system via a transformation matrix, and sensitivity and transverse sensitivity of each sensor axis are then calculated on the basis of the transformed sensitivity vectors either directly or following a further transformation. The method enables rapid, precise calibration of all sensitivities of a magnetic field sensor, since it does not require any orthogonal magnetic fields.

  • Patent number: 11378419
    Abstract: The present disclosure relates to a design for operating an angle sensor. A first sensor signal is output from a first sensor element on the basis of a magnetic field, which is dependent on an angle of rotation of a measurement object, at the location of the first sensor element. A second sensor signal is output from a second sensor element on the basis of the magnetic field that is dependent on the angle of rotation of the measurement object at the location of the second sensor element. During a calibration mode of the angle sensor, in which a rotation of the measurement object is performed, a first offset value of the first sensor signal, a second offset value of the second sensor signal and an amplitude correction value are determined on the basis of signal amplitudes of the first and second sensor signals. The first and second offset values ascertained during the calibration mode and the amplitude correction value are stored for use in an operating mode of the angle sensor.

  • Patent number: 11372023
    Abstract: A device probe includes a primary probe arm and a subsequent probe arm with a slip plane spacing between the primary probe arm and subsequent probe arm. Each probe arm is integrally part of a probe base that is attachable to a probe card.
