  • Publication number: 20210358069
    Abstract: The invention relates to a method (2) for safeguarding a logistics area (100), comprising the steps: monitoring a first control zone (9a); detecting whether a first vehicle module (23a) is present in the control zone (9a), wherein the first vehicle module (23a) is matched to the control antenna unit (15a, 15b); setting a safety status indicator (IS) in a first vehicle processing unit (25a) of the first vehicle module (23a) in response to detecting the first vehicle module (23a) in the control zone (9a, 9b); maintaining the safety status indicator (IS) in the first vehicle processing unit (25a), even when the first vehicle module (23a) is leaving the control zone (9a, 9b); monitoring an enabling zone (13); detecting whether the first vehicle module (23a) is present in the enabling zone (13), and deleting the first safety status indicator (IS) when it is detected that the first vehicle module (23a) is present in the enabling zone (13).

  • Publication number: 20210340805
    Abstract: A gate safety system for preventing collisions between a vehicle and a gate is provided, the system having a gate module with a vehicle module, a gate antenna unit and a gate processing unit. The gate processing unit is adapted for defining a first gate warning zone and for determining whether a vehicle module is present within the first gate warning zone. The vehicle module includes a vehicle antenna unit and a vehicle processing unit adapted for defining at least one first vehicle warning zone for determining whether the gate module is present within the vehicle warning zone. A lock safety system, two methods for operating the gate safety system and the lock safety system, and two computer programs are also provided.

  • Patent number: 10957202
    Abstract: A vehicle safety device for warning persons in traffic has an antenna unit having at least a first antenna, a second antenna, and a third antenna. The antennas are mounted spaced apart from each other in a predetermined spatial relationship at predetermined positions on a vehicle to be safe-guarded. Each antenna generates an electromagnetic field. The vehicle safety device also has a control unit in electrical communication with the antenna unit, which defines a warning zone for the vehicle and determines whether a warning module matched to the antenna unit is located within the warning zone.

  • Publication number: 20150286759
    Abstract: The present invention relates to a computer-implemented method for a hybrid simulation of an electric power distribution network and an associated communication network connected therewith to determine a time delay between an event occurring in the power distribution network and a desired effect of a performed measure in the power distribution network, the measure having been decided on by means of a decision-making algorithm as a reaction to the event.

  • Patent number: 9035759
    Abstract: An approach warning system includes at least one marking module and a warning module. The at least one marking module comprises a marking module transmission unit configured to emit electromagnetic signals, and a motion detector configured to detect a motion. The at least one marking module is configured to emit presence signals as the electromagnetic signals when a motion is detected. The warning module comprises a reception unit configured to receive the electromagnetic signals emitted by the at least one marking module, and an output device configured to emit an approach warning. The warning module is configured to emit the approach warning via the output device dependent on a reception of the presence signals emitted by the at least one marking module.

  • Patent number: 8917188
    Abstract: The present invention relates to a method for detecting and warning against wrong-way drivers, the method comprising the following steps: a) establishing a radio field over a roadway section to be monitored and at least substantially transversely to a predetermined correct driving direction of the roadway section, the radio field having at least two radio field sections that are spaced apart when viewed in the driving direction and have associated reception field strengths; b) detecting attenuations of the reception field strengths of the radio field sections that occur due to radio shadowing during driving through the roadway section; c) determining the sequence of the radio field sections in which an attenuation of the respectively associated reception field strengths has been detected; d) comparing the determined attenuation sequence with the correct driving direction; and e) initiating at least one warning signal if the attenuation sequence runs opposite to the correct driving direction.
