Linkage of position sensor |
January 25, 2000 |
| An extremely reliable and effective position sensor is provided at low cost for determining the relative position of a mechanical linkage with respect to a reference point. The position sensor includes a rotor or bracket which is mechanically coupled to the linkage and contains at least |

Rotary position sensor with improved bearing tolerance |
November 9, 1999 |
| An angular sensor has a shaped dual magnet structure carried upon a pole piece having a generally "c" shaped cross-section. The magnet and pole piece define a generally circular linear field which is concentric about the axis of rotation of the complete rotor. A Hall effect device is |

Rotary position sensor with improved bearing tolerance |
August 25, 1998 |
| A rotary position sensor having a dual magnet structure interconnected by a pole piece forming a varying dimension air gap. The magnets, the pole piece and the air gap between the magnets define a closed magnetic circuit. A Hall effect sensor is fixedly mounted in the air gap and is |
