Abstract: A safety system for localizing a person or object has a control and evaluation unit, at least one radio location system, and at least one spatially resolving sensor for the position determination of the person or object. The radio location system has arranged radio stations, wherein at least one radio transponder is arranged at the person or object. Position data and classification data of the person or object can be determined by means of the radio location system. The position data and the classification data can be transmitted from the radio station to the control and evaluation unit and position data and contour data of the person or object can be determined by means of the spatially resolving sensor. The control and evaluation unit is configured to compare the position data of the radio location system and the position data of the spatially resolving sensor.

Abstract: A method of protecting humans in an environment of a moving machine is provided that comprises the environment being monitored by means of a protective device that is configured to detect one or more kinematic parameters of a respective object located in the environment and controlling the moving machine in dependence on detected kinematic parameters of the respective object to initiate a protective measure. The protective equipment here detects the polarization properties and a movement modulation of the respective object in dependence on which the respective object is classified with respect to whether the respective object is a human. In particular only when the respective object was classified as a human, the protective equipment controls the moving machine to initiate the protective measure in dependence on detected kinematic parameters of this respective object.
