Patent ID: 7174795

Claim:
An integrated sensor for measuring the relative rotational movement between an input shaft and an output shaft and for measuring the angular position of said shafts, said integrated sensor comprising: an input shaft; an output shaft axially aligned with said input shaft for rotation about an axis; a support housing for rotatably supporting said output shaft for rotation about said axis; a torsion bar interconnecting said shafts for allowing relative rotational movement between said shafts in response to a predetermined torque; a wheel supported by said output shaft for rotation with said output shaft; a torque sensing mechanism disposed about said shafts for measuring relative rotational movement between said input shaft and said output shaft; an incremental sensing mechanism responsive to the rotation of said wheel for generating a incremental output indicative of the incremental angular position of said wheel; a segment sensing mechanism for providing a segment output indicative of the angular segment in which said wheel is disposed; and a sensor casing supported by said housing and supporting at least portions of said sensing mechanisms.
