Abstract
An active safety apparatus adapted for a disk or circular knife or saw is based on optical surveillance apparatus. The apparatus provides a precise boundary for a protected volume surrounding the blade. The apparatus creates four corner edges for the protected volume, which is a cuboid or a right frustrum. Appearance of an operator hand, recognized by glove color, in the protected volume causes immediate, active stopping of a servomotor used to rotate the saw blade.
