Claim Text:
1. A system including an auto-sensing circuit for determining characteristics of a conduit, positioned to undergo a bending operation by a bender, the bender having a shoe mounted on shoe shaft about which the conduit is to be bent, the system comprising: a frame; a motor; a microprocessor in communication with the motor used to perform the bending operation, said microprocessor is configured to provide a motor control signal to said motor to control the operation of the motor; a member mounted on said frame and moveable relative to said frame, the conduit is capable of being directly engaged with said member to cause movement of said member relative to said frame, wherein the member is in a first position relative to said frame when the conduit is not directly engaged with the member, and the member is moved to a second position relative to said frame when the conduit directly engaged with the member; a switch in communication with said microprocessor and in communication with said member; and wherein when the conduit directly engages the member, the member moves from the first position to the second position and the member activates the switch to send a signal to said microprocessor, providing information regarding a characteristic of the conduit to be bent to said microprocessor, and said motor control signal provided to said motor is based upon said information.
