Abstract:
1. A sensor system, the system comprising: a drive shaft; an engagement member supported on the drive shaft; a motor configured to drive the drive shaft and the engagement member supported on the drive shaft; a detectable feature comprising a rotary member supported on the drive shaft such that movement of the drive shaft by the motor changes a state of the detectable feature; at least one sensor arranged to detect the state of the detectable feature; circuitry configured to provide a signal in response to a change in the state of the detectable feature detected by the at least one sensor; a seating surface against which the at least one sensor is retained; and a bias member arranged to press the at least one sensor against the seating surface to retain alignment of the at least one sensor relative to the drive shaft.
