Patents by Inventor Alois Christiaens

Alois Christiaens has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Magnetic device with flux return strip
    Patent number: 6674208
    Abstract: A magnetic device having a stator assembly having a magnetic flux return path comprising at least a pair of pole plates located a fixed distance apart from each other and at least one flux return strip pressed between each pair of spaced apart pole plates, and a rotor assembly having permanent magnetic material and being disposed for rotation relative to the stator assembly. Use of the flux return strip eliminates the need for a housing of ferrous material to complete the flux return path and facilitates flexible design of light-weight non-metallic housings and mounting systems or integral mounting to mating components.
    Type: Grant
    Filed: September 6, 2002
    Date of Patent: January 6, 2004
    Assignee: Siemens VDO Automotive Corp.
    Inventors: David J. Ineson, William Loxsom, Alois Christiaens

  • Magnetic device with spaced apart pole plates, flux return strip and electrical connector having integral mounting
    Patent number: 6492751
    Abstract: A magnetic device having a stator assembly having a magnetic flux return path comprising at least a pair of pole plates located a fixed distance apart from each other and at least one flux return strip between each pair of spaced apart pole plates, and a rotor assembly having permanent magnetic material and being disposed for rotation relative to the stator assembly. The device further includes an electrical connector. Use of the flux return strip facilitates flexible design of the electrical connector for integral mounting of the device to mating components or flexible design of light-weight non-metallic housings and mounting Systems for mounting of the device to mating components.
