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： In a method for operating a technical installation that includes an outer zone, a danger zone, an access zone which provides for access from the outer zone to the danger zone, a light curtain for monitoring the access zone, and at least one mobile system: a protective field is generated and activated in the access zone by the light curtain before entry of the at least one mobile system into the access zone; when the at least one mobile system approaches the access zone, a mobile communication unit of the at least one mobile system transmits a request signal to a stationary communication unit of the light curtain; and after reception of the request signal by the stationary communication unit the protective field is deactivated by the light curtain. A technical apparatus is configured to carry out the method.

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 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： 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.

摘要： A device for transmitting data includes a transmitter for generating a frequency-modulated output signal. The transmitter includes a phase-locked loop for adjusting an output frequency of the output signal to a carrier frequency, and a coupling circuit for coupling a data stream into the phase-locked loop. The output signal modulated in frequency by the coupled-in data stream has an output frequency variable over time, and the coupling circuit includes a compensation unit, which couples a compensation signal into the phase-locked loop. The compensation signal compensates at least approximately for an adjustment of the output frequency to the carrier frequency carried out by the phase-locked loop.

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： 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： 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.
