Contactless linear angular position sensor having an adjustable flux concentrator for sensitivity adjustment and temperature compensation

Ronald J Wolf, +1 more
TL;DR: An angular position sensor for sensing the angular position of a pivotally mounted device includes a magnetically sensitive device, such as a Hall effect IC, and a plurality of flux concentrators, rigidly disposed relative to the Hall Effect IC, forming an assembly as discussed by the authors.
Patent

Mechanically adjustable linear-output angular position sensor

Ronald J Wolf, +1 more
TL;DR: An angular position sensor for sensing the angular position of a pivotally mounted device includes a magnetically sensitive device, such as a Hall effect IC, and a plurality of flux concentrators, rigidly disposed relative to the Hall Effect IC, forming an assembly as mentioned in this paper.
Patent

Temperature stable proximity sensor with sensing of flux emanating from the lateral surface of a magnet

Ronald J Wolf, +1 more
TL;DR: A ferrous object sensor assembly as mentioned in this paper consists of a permanent magnet and a magnetic flux responsive sensor having a sensing plane which produces an electrical output signal which varies as a function of the change in magnetic flux density.
Patent

Gear tooth sensor with improved resolution and stability

Ronald J Wolf, +1 more
TL;DR: In this article, a gear tooth sensor with increased sensitivity and temperature tolerance enables relatively small ferrous targets to be detected using a Hall effect IC (HIC) and flux concentrators.
Patent

Contactless angular position sensor

Ronald J Wolf, +1 more
TL;DR: An angular position sensor (20, 20', 200) for sensing the angular position of a pivotally mounted device (28) includes a magnetically sensitive device (24, 210), such as a Hall effect IC, and a plurality of flux concentrators (44, 46, 206), rigidly disposed relative to the Hall effect, forming an assembly.
