International Classification:

G01B 7/14

US Classification:

32420713

Abstract:

A linear position sensor assembly having a magnetic shield minimizes interference (noise) from adjacent electrical and electromagnetic devices, particularly solenoids. The sensor assembly includes a permanent magnet linear contactless displacement (PLCD) sensor comprising a pair of magnetic field sensors which are spaced apart by a member of high magnetic permeability such as a metal bar. The sensors and metal bar are enclosed, i.e., surrounded on three sides, by a cover or shield of high magnetic permeability material such as steel or mu metal, for example. A permanent magnet is disposed in sensed proximity to the sensors and translates with a clutch actuator component. When the clutch actuator component translates axially, the two field sensors provide a signal to associated electronics having high linearity, low noise and no deadband.

Michael E. McLeod - Grosse Ile MI

International Classification:

A47C 112

US Classification:

297335

Abstract:

A seat including a seat back and a seat bottom which is pivotally mounted is disclosed. The seat bottom is pivotally mounted for rotational movement between a first position wherein the seat bottom is substantially horizontal and a second position wherein the seat bottom is angled relative to a horizontal plane. The seat also includes means for maintaining the seat bottom in a number of positions intermediate the first and second positions. An occupant of the seat can select a seat bottom position which provides the best balance between the shock absorbing functions provided by the knees and the posterior.
