Abstract: A light source or projector for a near-eye display includes a light source subassembly optically coupled to a waveguide concentrator. The light source subassembly may include several semiconductor chips each hosting an array of emitters such s superluminescent light-emitting diodes. The semiconductor chips may be disposed side-by-side, with their emitting sides or facets coupled to the waveguide concentrator, which provides a tight array of output light ports on a common output plane of the concentrator. The output diverging beams at the array of output light ports are coupled to a collimator, which collimates the beams and couples them to an angular scanner for scanning the collimated light beams together across the field of view of the display.

Abstract: A motor vehicle having a frame-like assembly carrier as a component of a bodywork in the front end region of the motor vehicle which is driven by means of an internal combustion engine. The assembly carrier has an inner side and an outer side and includes a plurality of web-like carriers. In the installation position of the assembly carrier, two lateral carriers spaced apart from each other are connected by an upper carrier with a frame being formed. The upper web-like carrier has at least one air passage defined by the upper carrier which leads from the outer side to the inner side of the assembly carrier. A suction system is arranged on the inner side of the assembly carrier for supplying the internal combustion engine with air. At least one air inlet opening of the suction system adjoins at least one air passage of the upper carrier.

Abstract: A conduit carrying gaseous matter has a device inside it forming a low-lying sump for separating and collecting non-gaseous matter. The device fits within a flexible section of the conduit and includes a barrier plate oriented generally horizontally to longitudinally divide a length of the conduit into a gas-carrying passageway (above the barrier plate and a sump (below the barrier plate, a spacer extending from a lower surface of the barrier plate, and first and second frame members extending from an upper surface of the barrier plate at spaced-apart locations. The spacer and the frame member contact inner surfaces of the conduit to positively position the barrier plate within the conduit, and the frame members are oriented obliquely to one another to urge the flexible section of the conduit into a bent shape having a lowest portion defining the sump.

Abstract: An apparatus for improving the performance of a radial compressor 36 forming part of an inlet system of an engine 10 is disclosed in which the configuration and positioning of a flow management device 137 used to generate pre-whirl is optimized so as to produce a pressure drop below a maximum acceptable level. An inlet duct ‘I’ connected to the radial compressor 36 has a tapered end portion so that a flow management device 137 of a larger diameter d2 can be accommodated than the diameter d1 of an inlet port ‘IP’ to the radial compressor 36.

Abstract: In one form the present invention provides an apparatus in an airflow path before a particle detector, wherein the apparatus removes a substantially constant proportion of all sizes of airborne particles from the airflow over time. In an example the apparatus includes a flow splitting arrangement configured to divide a fluid flow into a plurality of sub-flows, the splitting arrangement 10 including means for defining a plurality of substantially identically dimensioned flow apertures configured to direct a portion of the fluid into a respective sub-flow.
