    摘要: A vent assembly that can be concealed when in a closed configuration is provided in one embodiment, the vent assembly comprises a base member and a guide member secured to a mounting surface of a duct or other passageway. A flexible rod is fixedly attached to the base member and slideably disposed within a channel defined by the guide member. A panel is disposed on or around the flexible rod and between the base and guide members. An actuator is able to deform the rod such that the panel moves away from the terminal opening of the duct, thereby opening the vent. A fluid distribution system incorporating vent assemblies in accordance with the present invention is also provided.

    摘要: An electronic assembly includes a flexible multilayer substrate having integral electrically-conductive traces that also includes, as a lowermost layer, a metal foil. A plurality of uppermost layers, likewise including a metal foil, form a thin barrier member that is sealingly attached to the substrate's other layers. In this manner, a plurality of electronic components, mounted on the substrate's other layers so as to be electrically interconnected with the traces before sealingly attaching the barrier member, are encapsulated within metal foil to provide an environmentally-sealed assembly featuring improved resistance to moisture diffusion and penetration/permeation of other substances characteristic of the assembly's service environment into the assembly. A filler material, also encapsulated within the metal foil, is operative to neutralize a predetermined amount of a penetrant, further improving the operability and service life of the assembly. Preferably, a relatively-rigid polymeric material is formed in touching contact with the substrate, as by overmolding the plastic material on the environmentally-sealed assembly, to thereby provide a plastic part incorporating the assembly.

    摘要: There is disclosed herein an intake manifold for a port-injected internal combustion engine, comprising: a manifold body 10 having an interior plenum 12, and a runner 14 extending outward from the manifold body 10, wherein the runner 14 has a distal end 16 and a passage 18 therethrough in communication with the plenum 12. The distal end 16 of the runner 14 has a socket 20 therein into which an EFI 50 may be operatively mounted, and a first keying feature 22 formed therein for aligning the EFI in a first predetermined orientation when the EFI is engaged with the socket 20 and keying feature 22. The manifold may further include a second keying feature 42 formed in the runner end 16 for aligning a coil-on-plug spark plug ignition coil 80 in a second predetermined orientation when the coil 80 is engaged with the second keying feature 42. The manifold may also include a means 30 for electrically connecting a signal source to the injector 50 and/or coil 80, arranged such that the EFI/coil may each be mechanically and electrically engaged with the manifold and signal source in essentially a single step.
