Safety devices for saws

A saw configured to motivate a blade and cut a workpiece, wherein the saw is configured to be in a first operating condition and a second operating condition, the saw comprising:

• at least one sensor, wherein said at least one sensor is configured to detect whether the saw is in the first condition or the second condition, and wherein said at least one sensor is configured to output a signal which is indicative of whether the saw is in the first condition or the second condition;
• and
• a visual feedback system positioned to provide visual feedback to an operator of the saw, wherein the visual feedback system comprises a light emitter, wherein said light emitter is in communication with said at least one sensor, wherein said light emitter is configured to aim a first light beam toward the blade when said at least one sensor detects the first condition such that the operator of the saw perceives the first light beam emanating from the light emitter, and wherein said light emitter is configured to aim a second light beam toward the blade when said at least one sensor detects the second condition such that the operator of the saw perceives the second light beam emanating from the light emitter.

A safety device configured to be used with a saw, wherein the saw includes a blade at least partially extending through a work surface adjacent the blade, the safety device comprising:

• a light emitter positioned above the work surface, wherein said light emitter is configured to aim a first light beam and a second light beam toward the blade such that an operator of the saw perceives the first light beam and the second light beam;
• and
• a sensor, wherein said sensor is configured to detect a first saw condition and a second saw condition, wherein said light emitter is configured to be in communication with said sensor, wherein said light emitter is configured to emit the first light beam when said sensor detects the first saw condition, and wherein said light emitter is configured to emit the second light beam when said sensor detects the second saw condition.
