Abstract
Machine vision apparatus tracks a distinctive object in relation to a hazardous location on a work surface of a modified band saw in two, three, or four (3-D+T) dimensions, and calculates whether to send an “immediate shut-down signal” to the band saw. Cameras and an image processor are mounted on the band saw. The signal causes an integrated blade-arresting or stopping mechanism to immediately shift the idler wheel, removing blade tension and disconnecting the blade which is then braked to a complete, safe stop before an approaching blue-gloved hand can touch the blade.
