  • Assembly using a magnetic field sensor for detecting a rotation and a linear movement of an object
    Patent number: 10323958
    Abstract: An assembly has a base structure, a rotatable structure, a first magnet coupled to the base structure, a second magnet coupled to the rotatable structure, and a magnetic field sensor. The magnetic field sensor can identify at least one condition (i.e., position) of the assembly.

  • Current sensor
    Patent number: 10247758
    Abstract: A current sensor includes a ferromagnetic core having a substantially central opening for receiving a current conductor and at least two gaps portions, each of the gap portions having an associated gap spacing. A detector of the current sensor includes at least one first sensing element disposed in a first one of the gap portions and configured to generate a respective first magnetic field signal in response to a first magnetic field generated in the first gap portion in response to a current through the current conductor. The detector also includes at least one second sensing element disposed in a second one of the gap portions and configured to generate a respective second magnetic field signal in response to a second magnetic field generated in the second gap portion in response to the current through the conductor. A method of sensing a current through a current conductor is also provided.
