Abstract: A roof module for forming a vehicle roof on a motor vehicle has a panel component whose outer surface at least partially forms the roof skin of the vehicle roof, the roof module has at least one environment sensor, and the environment sensor being configured to send and/or receive electromagnetic signals for detecting the vehicle environment, and the panel component being made of a material which is impermeable to the electromagnetic signals of the environment sensor. The panel component has at least one cutout through which the electromagnetic signals of the environment sensor can pass.

Abstract: A roof module for a motor vehicle may have a roof skin, a roof frame on a vehicle body and have at least one transverse frame part extending in the transverse roof direction and a longitudinal frame part extending in the longitudinal roof direction on either side of a longitudinal center roof plane, and a roof opening system having a lid element configured to be displaced on guide rails, which are part of the longitudinal frame parts of the roof frame, in the longitudinal roof direction relative to the roof frame, and/or a solid roof element having a transparent see-through portion and being rigidly connected to the roof frame, having a sensor system comprising at least one sensor module which has at least one environmental sensor and is located outside of the roof opening and/or outside of the transparent see-through portions and is covered by a cover element.

Abstract: A roof module for a motor vehicle, in particular a passenger car, is proposed, the roof module having a roof cladding, which forms an outer visible surface of the roof module, and at least one sensor module having an environment sensor for sensing a vehicle environment during an autonomous or partially autonomous operation of the motor vehicle. A viewing area can be formed in the roof cladding for the environment sensor and the viewing area can be provided with a cleaning element.

Abstract: A roof module for forming at least a part of the vehicle roof on a motor vehicle, the roof module having a panel component whose outer surface at least partially forms the roof skin of the vehicle roof, the roof module having at least one environment sensor configured to send and/or receive electromagnetic signals for detecting the vehicle surroundings. The roof module has at least one antenna module configured to receive and/or send radio signals.

Abstract: A roof module of a motor vehicle having a roof substructure, a roof cladding, which forms an outer visible surface of the roof module, and at least one sensor module having an environment sensor for sensing a vehicle environment, the roof cladding having a central section having a curved surface and at least one edge section, which adjoins the central section and whose incline is larger than the incline of the central section and which is transparent to the environment sensor at least in the area of a signal cone of the environment sensor. The environment sensor being at least partially disposed below a roof surface defined by the roof cladding.

Abstract: A roof module for realizing a vehicle roof on a motor vehicle, the roof module having a panel component whose outer surface forms at least a portion of the roof skin of the vehicle roof, the roof module having at least one environmental sensor which can send and/or receive electromagnetic signals to detect the vehicle environment. The environmental sensor is mounted on the roof module in such a manner that it can be displaced between an inoperative position and an operative position, the environmental sensor being displaceable between the inoperative position and the operative position by a drive mechanism.

Abstract: A railway vehicle has, located centrally on the end of a car body 1, a coupling device and at least one shock absorbing device 9, 10, which has a permanently deformable support element. To achieve an effective protection against under-running in an impact the, individual shock absorbing elements 9, 10 are parallel to one another underneath a horizontal plane that contains a coupling device 4.

Abstract: A rail vehicle has a longitudinal direction and includes an undercarriage, a crossbeam held against the undercarriage, extending transversely to the longitudinal direction of the superstructure and adapted for being seated on a bogie or similar structure. A mechanism is provided for elastically holding the crossbeam to the undercarriage.

Abstract: The packing can be used for mixing or for exchange processes in exchange columns. The packing comprises at least one group of layers perpendicular to the column axis which has deflecting surfaces connected to a central connecting bridge and which are bent outwardly of the bridge in alternating fashion to define a X-shape. The adjacent layers can be provided with outer bridges which are bent around to form hook-shape portions for engaging about an adjacent layer.The packing can be produced by simple stamping and bending steps.

Abstract: The packing elements are made of a strip of foil-like material which has at least one trickle surface for a descending flow of liquid. This surface is provided with alternating smooth portions and finely-fluted portions which extend over a height of at least five millimeters. In addition, at least the smooth portions are perforated. The packing element may be formed of a plurality of flat corrugated plates, or may be spirally wound from a continuous strip to form an ordered packing or may be in the form of cylinders to form a random packing.
