Walter Haeussermann 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 field control
    Patent number: 4313077
    Abstract: A torque control for an electromechanical torquing device of a type wherein there occurs variable clearance between a rotor and field. A Hall effect device senses the field present, which would vary as a function of spacing between field and rotor, and the output of the Hall effect device controls the power applied to the field so as to provide a well-defined field and thus a controlled torque to the rotor which is well-defined.
    Type: Grant
    Filed: January 11, 1980
    Date of Patent: January 26, 1982
    Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space Administration
    Inventor: Walter Haeussermann
  • Velocity measurement system
    Patent number: 4093917
    Abstract: A velocity sensor for sensing the speed of a moving conductive body employing an E-shaped magnetic core having a pair of spaced Hall effect devices positioned on the end of the central core, the ends of all cores being arranged adjacent to the path of the moving conductive body. The difference in output voltage registered by the two Hall effect devices is indicative of the speed of the conductive body.
