The present invention is directed to a light pipe having an improved structure of prisms. The tool has an elongate housing containing a pneumatic motor. Valve oscillation and debris controlled by means of a flow-control-debris-diverter with aided waterbuffer technology for quiet operation. The impact actuator may receive a haptic effect signal and in response cause the mass to contact the end stop to generate a haptic effect. A pulley is attached to the pivot-arm for engaging the belt and receives a belt load that generates a belt force component that is transmitted to the cylindrical member A torsion spring having one end connected to the base and another end interconnected to a damping means generates a damping force component acting in the opposite direction as the belt force component. The representation provides information concerning latchunlatch operations of a plurality of cam elements that control onoff states of a plurality of output devices and that form the plurality of output cam profiles.
