Patent attributes
A system for re-calibrating a machine includes an arm having a first end and a second end opposite the first end. The arm is configured to be coupled to a frame of the machine and to move within a range of motion during an active state of the machine. The system includes a target element on the first end of the arm, the target element including an outer surface and a projection extending away from the outer surface. A portion of the outer surface defines an eccentric surface along the target element. The system includes a magnetic field sensor coupled to the frame and configured such that the sensor is operable to detect the projection 1) in response to the arm being positioned outside of the range of motion and concurrently 2) when the machine is not in the active state.
