What if the interlock circuitry was designed that if it fails, it fails in a safe way? For example, if a short takes place, a fuse could blow. Lack of current or voltage could be detected. Power to the laser or mechanical hazard would then be interrupted. Feedback path would have to be quick to avoid a hazard. Eric Petitpierre Pulsecom Herndon, VA [email protected]
