摘要:
Conductors supported integrally with engine structure such as air intake manifolds and the like provide interconnection between engine components without the need for separate conventional wiring harnesses. The conductors take their mechanical strength from the underlying physical object and thus can be lighter than a freestanding harness. Connectors allow traces to continue across points of mechanical interface between structural components and allow wiring of engine components to be accomplished in the same operation as their physical assembly.

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.

Method of manufacturing a multi-layer printed circuit board adapted for reduce interfacial sheer stresses includes a laminate substrate having a top layer forming a first major surface, a middle layer having a predetermined thickness and a bottom layer forming a second major surface opposed to the first major surface. Etch resists are disposed on the first and second surfaces corresponding to reverse images of desired conductor patterns. The first and second surfaces are thereafter etched and the photoresist removed. The laminate substrate is secured via a low modules adhesive layer to a major surface of a base. The middle layer of the laminate substrate is thereafter selectively etched so as to isolate selected portions of the first and second surfaces and to define inner connect regions therebetween having a height equal to the predetermined thickness.

A circuit board assembly is disclosed comprising a pair of three-dimensional substrates having integral, metallized connectors. The connector of the first substrate protrudes therefrom, while the connector of the second substrate is recessed therein. The geometries of the protruding connector and the recessed connector are different such that they deform when assembled to provide an electrical connection and a detachable physical connection. In one embodiment, the recessed connector has a parabolic cross-section and the protruding connector has a circular cross-section. A flexible molded edge connector for the circuit board assembly is also disclosed.

An inert gas air horn distribution device employs a labyrinth with a baffle to clean the nitrogen gas used to deposit flux on circuit boards before wave soldering operations. The baffle diverts the gas flow causing heavier flux particles to collect in the labyrinth while the lighter gas exits for use in depositing flux on the circuit boards. The labyrinth cleans the gas thereby keeping the knife clean which produces more uniform results with less maintenance.

An integrated engine combustion monitoring system that includes at least one structure comprising a light communication channel (LCC) and a sensor, which are embedded in a cylinder head gasket, for monitoring combustion composition, pressure, or temperature. The sensor and the LCC may be positioned between an air cavity or a material comprising a photorefractive gel or polymer. The sensor includes a sensing component that may have various shapes or configurations. The LCC comprises one or more materials, such as a polymer, which may be formed into a strand or other structural shape and incorporated into the cylinder head gasket. The other end of the LCC may be fabricated as part of one or more engine structures or it may be connected to other structures or components such as optical detectors or associated process control electronics.

An electronic system generally includes a flatwire electronic site and a flatwire bus electronically connecting the flatwire electronic site and an electronic device in the engine compartment. The flatwire electronic site has a flexible substrate with electronic components attached to the substrate for operation of the electronic device. The flatwire electronic site is mounted to the engine side of the bulkhead for thermal cooling of the flatwire electronic site. A cover is attached to the bulkhead which encloses a flatwire electronic site for environmental protection.
