Zusammenfassung:	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, recognised by glove colour, in the protected volume causes immediate, active stopping of a servomotor used to rotate the saw blade. Un aparato de seguridad activa adaptado para un disco o cuchillo o sierra circular basado en un aparato de vigilancia óptica. El aparato proporciona un límite preciso para un volumen protegido que circunda la cuchilla. El aparato crea cuatro bordes de esquina para el volumen protegido, que es un cuboide o un tronco recto. La aparición de la mano de operador, reconocida por el color del guante, en el volumen protegido da lugar al alto activo e inmediato de un servomotor usado para girar la cuchilla de sierra.
