A communication module for a system for transferring data by light beams includes a transmitter for emitting a light beam in which data to be transferred are encoded, and a receiver for receiving a light beam. The transmitter includes a light source, and the receiver includes a light sensor. The transmitter and receiver are disposed offset from each other in a vertical direction. The transmitter emits a light beam in a longitudinal direction. The receiver has a mirror, which can be pivoted about a pivot axis extending in the vertical direction between a folded-out position and a folded-in position. The mirror is disposed such that a light beam incident from the longitudinal direction is deflected toward the light sensor by the mirror in the folded-out position. A system for transferring data by light beams includes at least one first communication module and at least one second communication module.

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.

In a method for a data transmission between first and second modules, and a system having mobile parts for performing the method: the time bases of the first and second modules are synchronized; transmitters of the first module emit a light signal pulse individually one after the other and/or in numbered order in a respective time range; the particular receiver of the second module at which the strongest receive signal occurs is determined, the particular time range and/or the number of the particular time range being determined in which the strongest receive signal occurs; the determined time range and/or the determined number is/are transmitted from the second module to the first module; and the transmitter of the first module associated with the determined time range and/or to the determined number is determined and used for the subsequent data transmission from the first module to the second module.

In a method for operating a system, and a system, the system includes a mobile part drivable on a driving surface, and a load carrier. The mobile part includes a radar sensor connected to a control of the mobile part. The frequency spectrum of an intermediate frequency signal is determined, and, using pattern recognition, the frequency spectrum is compared with stored pattern samples, and the result of the comparison is conveyed to the control. The control actuates actuators such as a drive and/or steering unit of the mobile part as a function of the result of the comparison.

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.
