1. A miter saw comprising:
- a support structure having a cutting zone;
a blade supported by the support structure so that the blade may move into the cuffing zone;
a motor adapted to drive the blade;
a detection system to detect contact between a person and the blade; and
a reaction system adapted to create an impulse against movement of the blade into the cutting zone upon detection by the detection system of contact between the person and the blade.

Abstract
A miter saw is disclosed having a base, a blade supported by the base, a detection system adapted to detect a dangerous condition between a person and the blade, and a reaction system associated with the detection system to cause a predetermined action to take place upon detection of the dangerous condition. The blade is rotatable, and moves into a cutting zone to cut a workpiece. The predetermined action may be to stop the blade from rotating, to create an impulse against movement of the blade into the cutting zone, or to cause the blade to move away from the cutting zone.

17. A miter saw comprising:
-
a base having a cutting region;
a blade;
a brake system adapted to brake the blade; and
a linkage between the blade and base, where the linkage is configured to cause the blade to move away from the cutting region when the brake system brakes the blade.

19. A miter saw comprising:
-
a base;
a housing pivotally connected to the base;
a blade;
a mounting system holding the blade in the housing; and
a brake system adapted to brake the blade;
where the mounting system is configured so that the blade pivots into the housing when the brake system brakes the blade.

20. A miter saw comprising:
-
a base;
a swing arm supported by the base and adapted to move toward a workpiece to be cut;
a blade mounted to move with the swing arm to contact the workpiece when the swing arm moves toward the workpiece;
a detection system adapted to detect a dangerous condition between a person and the blade; and
a reaction system adapted to interrupt the movement of the blade and swing arm upon the detection by the detection system of the dangerous condition between the person and the blade. - View Dependent Claims (21, 22, 24, 25, 27, 28, 29)
