A wheel bearing is provided with a sealing device comprising in-cluding at least an outer structure and an inner structure together de-limiting a chicane passage having an inlet. The outer structure forms an annular gutter which is open radially outwards. The inlet of the chicane passage and the shrink-fitting portion of the outer structure are situated axially on either side of the gutter. The shrink-fitting portion of the outer structure is situated on one side of a reference plane of the outer ring, perpendicular to the axis of revolution and tangential to the end wall of the outer ring opposite to the chicane passage and to the gutter.

The invention relates to a lighting unit comprising a flexible surface lighting fixture and a control unit. The surface lighting fixture comprises a flat carrier material with a, in particular textile-based, flexible, flat circuit carrier, which is equipped on a front side with a plurality of lighting devices that are interconnected by electrical lines formed in or on the circuit carrier. The control unit comprises a housing arranged on an edge of the surface lighting fixture and mechanically connected to it. For connection to the control unit, the circuit carrier of the surface lighting fixture has at least one elongated flexible printed circuit board tongue with conductor tracks, which is guided into the control unit through a slot in a wall of the housing of the control unit.According to the invention, the housing comprises an inner wall on the inside of the slot, which defines a cavity with the wall of the housing having the slot, which cavity is open on one side towards an interior of the housing and forms a chicane through which the printed circuit board tongue is guided from outside the housing to inside the housing under at least one bend, in particular an S-shaped bend, wherein the cavity with the printed circuit board tongue guided through is filled with a sealing compound.

The object of the present invention is a method for determining an optimal route by a road vehicle, which comprises the steps of retrieving information about the current location of the vehicle from the location module; retrieving information from the user about where he wants to go; information on possible routes is extracted from a road map provided with additional information on road constraints such as speed limits resulting from road signs and traffic regulations, chicanes, pedestrian crossings, intersections, level crossings; information on vehicle characteristics such as make, engine power, acceleration, energy expenditure is extracted from a database of vehicles, engines, transmissions, etc., on the basis of the information obtained, the optimal route is determined, with the optimal route is minimising the energy cost of the journey.

To provide a wheel bearing which combines a satisfactory sealing function and a large pitch circle diameter from the viewpoints of technical performance and monetary cost. A wheel bearing (10) includes a sealing device (66) including at least an outer structure (76) and an inner structure (78) that together define a baffle passage (S) having an inlet (E). The outer structure (76) defines an annular gutter (82) that opens radially outward. An inlet (E) of the baffle passage (S) and a shrink-fit portion (80) of the outer structure (76) are located on each axial side of the gutter (82). The shrink-fit portion (80) of the outer structure (76) is located on one side of a reference plane (PE) of the outer ring (20) that is perpendicular to the rotation axis (XX) and tangent to an end wall (70) of the outer ring (20) opposite the baffle passage (S) and the gutter (82).

A stormproof soffit assembly for venting an attic of a building and a method for installing the same are described herein. The stormproof soffit assembly is mountable on a wall of the building proximate an airhole in the wall opening on the attic. The stormproof soffit assembly comprises an inner vent member configured to extend along the wall of the building and forming an inner chamber having an air input port allowing air to enter the inner chamber; an exposed vent member forming an outer chamber, an upper portion of the outer chamber defining an air output port in fluid communication with the airhole in the wall; and a mesh extending between the inner chamber and the outer chamber and allowing air to flow therebetween. The air follows a chicane-shaped path when circulating through the stormproof soffit assembly between the air input port and the air output port.

This invention provides an optimization method for a magnetic compressor decompression device in an energy recovery accelerator, comprising: sequentially setting first to sixth bends along the beam direction to establish a chicane-structured magnetic compressor decompression device; determining the structure of the reverse-optimized beamline based on the decompression device; establishing constraints for a total deflection angle of 0, an anti-dispersion constraint, and a transfer matrix constraint, and solving the constraint conditions; establishing corresponding criteria with minimizing the slice center shift caused by coherent synchrotron radiation as the optimization objective; optimizing the variables of the reverse-optimized beamline based on the constraints and criteria; and reversing the placement of the reverse-optimized beamline to obtain the decompression device. This invention retains the advantages of conventional chicanes, such as a smaller deflection angle, which prevents over-compression, effectively reducing peak current intensity and helping to suppress slice center shift caused by CSR effects, thereby achieving lower emittance.
