Abstract: An HME device (1) has an outer housing (10) in two parts removably connected with one another by bayonet lugs (17) on one part (13) inserted in bayonet slots (48) on the other part (14) and twisted. An HME unit (50) has a tapered coupling at one end fitted on an internal port (45) in one part (14) so that it can be removed and replaced by separating the two parts of the housing. The outside of the HME unit (50) is spaced from the inside of the housing (10) by an annular bypass channel (55). A selector (31) has a rotatable plate that can be moved to cover either the passage through the HME unit or the bypass channel.

Abstract: Examples are disclosed herein that relate to vehicles, composite parts, and methods for forming a composite part for a vehicle. In one example, a vehicle comprises a composite part comprising a skin comprising one or more material layers. The composite part further comprises a stiffener comprising one or more material layers, wherein the stiffener comprises a flange and a web. The composite part also includes an additively manufactured sub-structure positioned between at least a portion of the skin and at least a portion of the stiffener. The additively manufactured sub-structure comprises at least one flange portion, at least one radius, and at least one radius filler. A polymer matrix is co-infused within the skin, the stiffener, and the additively manufactured sub-structure.

Abstract: An HME device has a housing (10) containing an HME element (25). The device has a first gas-flow passage through the device via the HME element (25) and a second gas-flow passage that by-passes the HME element. Flow is switched between the first or second flow passage by a pivoted shutter (30) that can be displaced by a rotatable knob (32).

Abstract: Parametric surfaces such as Attribute Based Modeling surfaces require methods of manipulating the interior of the surface. This invention provides several methods of manipulating these surfaces in a computationally efficient way. Particular attention is paid to surface continuity and discontinuity from G?1 to G2. Designers want to trim and join surfaces in an intuitive way; this invention provides such a method.

Abstract: A display device for displaying advertising material on a stair tread riser comprising a carrier adapted to be attached to a stair riser and an advertising plate adapted to be housed within the carrier.

Abstract: Attribute Based-Modeling surfaces requires uniform methods of calculating distances and weights in parameter space in order to create smooth and fair surfaces. This invention provides several methods of calculating distances and weights that have different characteristics yielding well behaved surfaces. The methods are computationally efficient and produce surfaces that are fair and smooth and have certain minimal energy characteristics that are desirable to various industries.
