  • Method of and apparatus for magnetically detecting the three-dimensional rotational position and movement of an object
    Patent number: 4661773
    Abstract: A magnetic axis is imparted to an object which effects three-dimensional rotational movement. The magnetosensitive semiconductor elements are disposed in the directions of three axes or two axes of a space determined for the object in such a manner that the elements are not in contact with the object. Any variation in direction of the magnetic axis resulting from movement of the object is detected by the magnetosensitive semiconductor elements. The detection signals from the magnetosensitive semiconductor elements are electrically processed so that the three-dimensional rotational position and movement of an object may be detected without contact and continuously.
