Abstract
Abstract A sensor for determining the operational position of an automotive suspension including two suspension members relatively removable with respect to another includes an assembly with a first component movable with respect to a second component, with the first and second components being relatively movable with respect to each other as a result of the movement of the vehicle suspension. A sensor according to this invention will further include, without limitation, a force generation device associated with the sensor components for generating a force with a magnitude which is related to the position of the suspension members with respect to one another and a transducer device associated with the force generation device for producing a signal which is related to the magnitude of the force, and hence, to the position of the suspension members with respect to one another.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
186 words
A sensor for determining the operational position of an automotive suspension including two suspension members relatively movable with respect to one another, comprising: a first sensor component movable with respect to a second sensor component; and means for attaching said first sensor component to one of said relatively movable suspension members and means for attaching said second sensor component to the other of said relatively movable suspension members such that said first and second sensor components will be caused to move with respect to one another when said suspension members move with respect to one another; said first sensor component comprising a housing with a force transducer means situated therein, with said transducer means being adapted to generate a signal proportional to a force imposed upon said transducer means; said second sensor component comprising a plunger telescopically received in said housing and bearing upon an elastically deformable member in contact with said force transducer means, whereby said plunger and said elastically deformable member will exert a force upon said transducer means which is proportional to the position of the suspension members with respect to one other.
