摘要： In a rail system with a rail and mobile parts movable along the rail, e.g., rail vehicles, a profiled part is arranged on the rail and includes a cavity, which, e.g., terminates at an opening into the environment. Regions of a mobile part, e.g., regions of each mobile part, at least partially project into the cavity, and at least one transmitter and receiver are situated in the respective region.

摘要： 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.

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 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 the 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.

摘要： A system includes a first communications unit, e.g., a transmitter, and a second communications unit, e.g., a receiver. The first communications unit has a controllable illumination device, which emits light modulated according to a predefined data flow, and the second communications unit has a camera, including an optical element and an image sensor. A light-sensitive surface of the image sensor has a plurality of lines of light-sensitive elements, and the image sensor is arranged such that the image of the illumination device projected onto the light-sensitive surface of the image sensor by the optical element is unsharply imaged and/or covers more than half of the light-sensitive surface and is scanned line by line, e.g., so that the image has stripes of different brightness and/or that the brightness profile induced transversely to the line direction spatially indicates the time characteristic of the data flow.

摘要： 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.

摘要： A system includes a first mobile part and a second mobile part, each being able to be moved in a movement plane of an installation. The first mobile part has corner modules at its outer corner areas, and the second mobile part also has corner modules at its outer corner areas. Each corner module has an electronic circuit together with transmitters and receivers such that modulated light is able to be emitted with the aid of the transmitters, and modulated light is able to be detected and demodulated with the aid of the receivers. The receivers have different sensitivities for light from different directions in space, in particular, the receivers of the respective corner module being situated in one plane with respect to this respective corner module.
