Abstract: A method for determining a protection zone with a protection radius about a wireless communication object transponder, wherein the method includes a) ascertaining a first indefinite position of the object transponder using a first locating system, b) ascertaining at least two definite anchor object distances between the object transponder and at least two anchor gateways with respective known positions via a definite distance measuring device using a two-way ranging method, and c) ascertaining the protection radius using a failsafe computing device which receives the first indefinite position from the first locating system and the at least two definite anchor object distances from the distance measuring device and determines the protection radius therefrom using the known positions of the at least two anchor gateways.

Abstract: A method for determining a definite safe distance between a wirelessly communicating object transponder and at least one anchor gateway in accordance with a two-way ranging method, wherein transmission and reception timestamps are detected for each communication message via the transponder and the at least one anchor gateway, each of the timestamps from the transponder and the at least one anchor gateway together with at least one respective piece of timestamp monitoring information are transmitted to a failsafe computing device, at least one check is implemented via the failsafe computing device, and the definite safe distance is determined via the failsafe computing device aided by the checked timestamps, where timestamp errors occurring during the detection of the timestamps are caused solely by the transponder or alternatively solely the one anchor gateway.

Abstract: A system and method for localizing a movable object that includes a first transmitter and a second transmitter which are arranged at a geometric distance relative to one another, wherein the first transmitter and the second transmitter each transmit a first signal and a second signal, wherein the first and second signal are in temporal synchrony relative to one another and furthermore a receiver is provided, which receives the first signal via receiving device and determines a first direction, from which the first signal is received, and receives the second signal and determines a second direction, from which the second signal is received, and a runtime difference between the first signal and the second signal, and where the position of the movable object is determined from the runtime difference, the distance, the first direction and the second direction by an evaluator.

Abstract: A method for distance measurement and data transmission in a continuous wave radar system is described. A continuous wave radar system has a transmit and receive module and at least one transponder device, a mobile control and monitoring device and an HMI system. Transponder devices are searched for with the aid of an unmodulated continuous wave signal as an interrogation signal, such that the transponder device can send a radio response signal to the transmit and receive module in response to the interrogation signal, as a result of which a data transmission takes place from the transponder device to the transmit and receive module. Upon completion of the data transmission a frequency-modulated continuous wave signal is generated in order to measure, on the basis thereof, a distance between the transponder device and the transmit and receive module.
