POWERED SAW HAND DETECTION AND CONTROL

Abstract: a powered saw includes at least one camera, a sensor, a saw blade, a motor configured to drive the saw blade, and an electronic controller including an electronic processor and a memory. the electronic controller receives an indication of an orientation of the saw blade from the sensor and determines a keep-out area based on the orientation of the saw blade, where the keep-out area corresponds to, or is defined relative to, the saw blade. images captured from the at least one camera are received by the electronic controller, where the captured images include at least a portion of the keep-out area. the electronic controller analyzes, using a machine learning (ml) model, the captured images to determine whether a portion of a hand is present in the keep-out area and, in response to detecting the portion of the hand in the keep-out area, executes a safety action.
