Beschreibung
Zusammenfassung:	A cam lift and reset assembly includes a cam mounted on a rotatable shaft having a cam profile effective to provide a lifting force to a contacted part thereon upon rotation of the shaft and movement of the cam profile of the cam relative to the contacted part from a rest position to a lift position. The assembly also includes an active material in operative communication with the shaft, the active material being operative to change at least one property of the active material in response to an activation signal so as to effect rotation of the shaft. The assembly further includes a reset device in operative communication with the shaft to provide a reset force to the contacted part and counter-rotation of the shaft and movement of the cam profile of the cam relative to the contacted part from the lift position to the rest position.
