Abstract: A method is provided using a safety system. The safety system has an electronic access system for a safety zone for objects, at least one radio transponder and at least one radio station to recognize the radio transponder, at least one control and evaluation unit that is connected to the radio station for evaluating the read radio transponder information, and at least one spatially bounded access zone having an access station. The safety zone is only accessible via the access zone so that the access zone can be passed through by the object before reaching the safety zone and after leaving the safety zone, with the access station being actuated when an object passes through the access zone. Permitted objects have the radio transponder, with the radio transponder having an identification whereby the object can be identified. The permitted objects having the radio transponder can pass through the access zone.

Abstract: A method using a safety system for localizing a person and/or object in a monitored zone having a control and evaluation unit, having at least one radio location system for the position determination of the person and/or object in the monitored zone, wherein the control and evaluation unit is configured to evaluate position data of the radio location system and status information of a spatially resolving sensor and, if a person and/or object is/are determined in the monitored zone by the radio location system, the control and evaluation unit is configured to set the spatially resolving sensor into operation at a non-reduced safety level and, if no person and/or no object is/are determined in the monitored zone by the radio location system, the control and evaluation unit is configured to set the spatially resolving sensor into operation at a reduced safety level.

Abstract: A safety system and a method for the localization of at least two vehicles have at least one control and evaluation unit and at least one radio location system. The radio location system has at least three arranged radio stations. At least one device has at least one radio transponder arranged at the vehicles. The radio location system is configured to determine position data of the radio transponder and thus to determine position data of the vehicles. The position data can be transmitted from the radio station of the radio location system to the control and evaluation unit and/or the position data can be transmitted from the radio transponder to the control and evaluation unit. The control and evaluation unit is configured to cyclically detect the position data of the radio transponder. The radio transponder has an identification and the control and evaluation unit is configured to distinguish the vehicles.

Abstract: A method and a system having a sensor for detecting legs of a person in a monitored zone having protected fields and for releasing a function of a vehicle, having a control and evaluation unit for evaluating the protected fields, wherein the sensor is configured to generate at least two protected fields, wherein a first protected field detects at least a part of a first leg of the person, wherein a second protected field detects at least a part of a second leg of the person, the control and evaluation unit is configured to determine whether at least a part of a first leg of the person was detected in the first protected field and at least a part of a second leg of the person was detected in the second protected field, and to transmit at least a release signal to the vehicle and thus to release the function when at least a part of a first leg of the person was detected in the first protected field and at least a part of a second leg of the person was detected in the second protected field, wherein the sensor is a time of flight sensor wherein at least one light transmitter transmits a light signal and at least one light receiver receives a signal reflected or remitted by the person, and the control and evaluation unit is configured to evaluate the received signal on the basis of the time of flight and to form object determination signals.
