Patent ID: 7174796

Claim:
A method of evaluating a tool in response to a member of the tool being moved from a first position to a second position, the method comprising: applying a first force to the member, the first force being operable to move the member from the first position to the second position; sensing a second force, the second force resulting from a resistance of the tool to the first force; and determining whether the second force exceeds a predetermined value; determining an event occurrence; determining whether the second force exceeds the predetermined value in response to the event occurrence; calculating an amount of work applied to the tool in response to the event occurrence, wherein the amount of work is calculated based on the second force and a distance between the first position and a position of the member when the event occurs; advancing a pawl along a plurality of detents of a ratcheting mechanism of the tool as a result of moving the member from the first position to the second position; determining whether the pawl has advanced to a final detent of the plurality of detents, wherein the event occurrence is determined in response to the pawl having advanced to the final detent; and determining whether an amount of work applied to the tool exceeds a predetermined work value in response to the event occurrence; and determining the tool passes evaluation in response to the amount of work applied to the tool exceeding the predetermined work value.
