SAFETY DEVICES FOR SAWS

摘要

In various embodiments, a saw(l?) can include a work surface (16) and a blade (12) at least partially extending through the work surface. In at least one embodiment, the saw can further include a sensor (40) and a light emitter (32), wherein the light emitter can be configured to emit a first light beam and a second light beam onto at least a portion of the work surface. In various embodiments, the sensor can be can be configured to detect a plurality of saw conditions and, owing to communication between the sensor and the light emitter, the light emitter can be configured to emit the first light beam onto the work surface when the sensor detects a first saw condition and emit the second light beam onto the work surface when the sensor detects a second saw condition.
