Abstract:
1. A tool for actuating a workpiece, the workpiece having a first contact surface and a second contact surface, the workpiece being actuated when the second contact surface is moved relative to the first contact surface and releasing energy when being actuated, said tool comprising: a fixed member for contacting the first contact surface of the workpiece; a movable member supported for generally linear movement relative to said fixed member, said movable member for contacting the second contact surface of the workpiece; a trigger mechanism for urging said movable member into engagement with the second contact surface, said trigger mechanism having stored energy therein and adapted to apply a load to said movable member whereby said movable member moves over a first range of movement for moving the second contact surface relative the first contact surface in response to said load for actuating the workpiece, and said stored energy moving said movable member when said movable member no longer detects a reaction force from the second contact surface to thereby move said movable member over a second range of movement in response to the stored energy; and a sensor for detecting at least a portion of said second range of movement of said movable member and generating a signal in response to said portion of said second range movement of said movable member whereby said sensor generates a signal at least when the workpiece is actuated.
