摘要： In a system and method for operating a system having a rail, a stationary unit, rail-guided mobile parts, and a slotted hollow waveguide, either a first one of the mobile parts or the stationary unit functions as a transmitter, and a second one of the mobile parts functions as a receiver. The transmitter is configured for the simultaneous transmission of an electromagnetic signal and an acoustic signal, e.g., at a first instant. The receiver, which is set apart from the transmitter, is configured to detect the arrival of the electromagnetic signal at a second instant and to detect the arrival of the acoustic signal at a third instant. The second mobile part has an evaluation unit which is configured to determine the distance between the transmitter and the receiver based on the acquired second and third instants.

摘要： In a method and system for position capture of a vehicle along a driving route, situated on a concrete floor having a reinforcement: the vehicle carries out a reference drive along the driving route, the vehicle records measuring points along the driving route, and each measuring point allocates a signal from the reinforcement to a position on the driving route; a reference profile of the driving route is determined based on the measuring points ascertained during the reference drive; the vehicle drives along the driving route and records further measuring points; a profile segment is determined from the further measuring points; the profile segment is uniquely allocated to a segment of the reference profile, e.g., using a correlation method; a position on the driving route is uniquely allocated to the vehicle with the aid of the profile segment allocated to the reference profile.

摘要： A receiver for a light transmission system includes a camera having an image sensor, and a light-sensitive area of the image sensor includes a plurality of rows of light-sensitive elements. The image sensor is configured such that the light-sensitive area of the image sensor is scanned row by row or column by column. An attachment element is arranged such that light incident on the light-sensitive area of the image sensor passes through the attachment element beforehand. The attachment element has at least one lenticular region and at least one planar region.

摘要： A system includes vehicles, a central control unit, and a stationary transceiver module connected to the central control unit via a bidirectional communications channel. Each vehicle has a transceiver module for bidirectional communication with the stationary transceiver module and/or a vehicle. The transceiver module has a controllable light source and a light sensor. The central control unit transmits driving orders to the vehicles via the stationary transceiver module. A first vehicle that is located within a spatial transmission area of the stationary transceiver module forwards a driving order to a second vehicle that is located outside the spatial transmission area of the stationary transceiver module, and the second vehicle transmits data via the first vehicle and the stationary transceiver module to the central control unit.
