  • Patent number: 8138878
    Abstract: The invention relates to a current-compensated choke with a ring core at least two coils composed in each case of the same number of windings, wherein in the interior of the ring core a non-conductive body is arranged with holes embodied in pairs in a mirror symmetrical manner to a symmetry axis of the ring core, wherein respectively one winding is guided through each hole of at least some of the pairs of symmetrical holes, and windings corresponding to one another of different coils are guided through the two holes comprising a pair, and a method for producing a current-compensated choke of this type.
    Type: Grant

  • Patent number: 6960912
    Abstract: In a magnetic sensor device, a positioning element is provided with receptacles for receiving one magnetic field sensor element each. The positioning element and the magnetic field sensor elements are manufactured in a way that they fit exactly together so that the positioning element exactly positions the sensor elements with respect to each other. The magnetic field sensor elements may be manufactured separately before they are put together to build the magnetic field sensor device.

  • Publication number: 20050017714
    Abstract: In a magnetic field sensor device, a positioning element is provided with receptacles for receiving one magnetic field sensor element each. The positioning element and the magnetic field sensor elements are manufactured in a way that they fit exactly together so that the positioning element exactly positions the sensor elements with respect to each other. Manufacturing of the device is made easy and cost effective by the opportunity to manufacture the magnetic field sensor elements separately before they are put together to build the magnetic field sensor device.
