1. A woodworking machine comprising:
- a support structure having a cutting zone;
a rotatable cutting blade supported by the support structure and adapted to be manually advanced by an operator at least partially into the cutting zone to cut a workpiece;
a motor adapted to rotate the cutting blade;
a detection system adapted to detect contact between a person and the cutting blade; and
a reaction system adapted to stop motion of the cutting blade into the cutting zone upon detection of contact but not proximity between a person and the cutting blade by the detection system.

13. A woodworking machine comprising:
-
a base configured to rest on a generally horizontal surface to support the machine during operation; a work surface supported by the base above the generally horizontal surface on which a workpiece may be cut; a work zone adjacent the work surface; a rotatable blade adapted to be manually advanced by an operator into the work zone to cut the workpiece; a motor to rotate the blade; a detection system adapted to detect contact between a person and the blade; and a reaction system adapted to stop movement of the blade into the work zone upon the detection of the contact but not proximity. - View Dependent Claims (14, 15)
