Abstract

Safety systems for power equipment are disclosed. The safety systems include a detection system (22) adapted to detect a dangerous condition between a person and a working portion (14) of a machine, such as accidental contact with the working portion, and a reaction system (24) associated with the detection system to cause a predetermined action to take place relative to the working portion, and a reaction system (24) associated with the detection system to cause a predetermined action to take place relative to the workpiece portion upon detection of the dangerous condition by the detection system. The detection system may be adapted to capacitively impart an electric charge on the working portion and to detect when that charge drops. The reaction system may be a brake system (28) to stop the working portion, a retraction system to retract the working portion, a system to cover the working portion, or some other system.
