  • Patent number: 12025681
    Abstract: A method for determining a sensitivity of a Hall sensor element in consideration of an interdependency between the temperature dependence of the sensitivity and the temperature dependence of the operational quantity of the Hall sensor element includes: identifying a reference sensitivity and a reference value of the operational quantity of the Hall sensor element; determining an instantaneous value of the operational quantity of the Hall sensor element on the basis of a drive signal of the Hall sensor element; and determining the sensitivity of the Hall sensor element on the basis of the reference sensitivity, the reference value of the operational quantity, the identified instantaneous value of the operational quantity, and the interdependency.

  • Patent number: 11977132
    Abstract: Magnetic-field sensor arrangement comprises a magnetic-field sensor for providing a sensor output signal based on a magnetic field acting on the sensor; an excitation-conductor array including selectively driveable excitation conductors spaced from the magnetic-field sensor; a driver for selectively driving the excitation conductors to generate different magnetic test fields in different drive states by driving a different excitation conductor, and to generate a set of detected output signal values of the magnetic-field sensor according to the different drive states; and evaluator configured to provide different parameter sets including comparison output signal values for the different drive states and representing variations of the architecture of the magnetic-field sensor including the excitation-conductor array, and further configured to determine, based on the set of detected output signal values of the magnetic-field sensor, that parameter set whose comparison output signal values exhibit a best match wi

  • Patent number: 6467980
    Abstract: An optical fiber cleaner includes a base having a well supported within an annular section. An absorbent material, such as a sponge or cotton ball, may be located within the well of the base. A cover mates with the base and holds a wipe in a preferred position over the well. The cover includes an aperture through which the wipe may be accessed. The cover may also include a hinged element, or lid, that closes over the aperture within the cover when the cleaner is not in use. The base may itself be an element of the lid of a push-pump mechanism. In such case, the well within the base is operationally connected to receive solvents from the pumping mechanism and the pumping mechanism, including the base, forms a cover for a solvent reservoir, such as a non-reactive bottle.
