Patent number: 8371196Abstract: A method of controlling a woodworking machine having a movable cutting tool. The method monitors a signal for a change indicative of a dangerous condition between the cutting tool and a person, senses movement of the cutting tool, and performs an action to mitigate the dangerous condition when the signal change and movement of the cutting tool are both detected. A woodworking machine including a detection system adapted to detect a dangerous condition between a person and a working portion of the machine and then to perform some action to mitigate the dangerous condition is also disclosed. A motion detection system is adapted to detect motion of the working portion and to disable the reaction system when the working portion is not moving.Type: GrantFiled: November 7, 2011Date of Patent: February 12, 2013Assignee: SD3, LLCInventors: Stephen F.
