International Classification:

H01Q 19/00

US Classification:

343850, 333246, 333247, 257664, 174266

Abstract:

The present invention consists of an electrical communications device including a three-dimensional substrate and a plurality of electrical devices attached thereto. The substrate is preferably a dielectric. The electrical device is preferably of the sort needed to conduct high frequency communications, such as a microwave antenna and photonic receivers and transmitters. The electrical devices are attached to the substrate at the connection points described by the intersection of a series vias and one of the substrate surfaces. The electrical devices are attached to the substrate in numerous ways, including solder, flipped chip ball bonds, wire bonds, or a gold stud assembly. In particular, the gold stud assembly is utilized to attach the antenna to the substrate, thereby providing a predetermined air gap therebetween.

International Classification:

G01M019/00

US Classification:

073/118100

Abstract:

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.

Abstract:

A system and method for soldering flat flexible cable to an electronic substrate using lead-free solder is disclosed. The method comprises bending conductive end portions of the flat flexible cable and inserting the bent conductive end portions of the flat flexible cable through slots that extend through the thickness of the electronic substrate. In so doing, a segment of the conductive end portion will protrude through the thickness of the substrate. The method further comprises of heating the flat flexible cable to a temperature of approximately 100 C. and then applying the lead-free solder to the area where the end portion protrudes through the thickness of the substrate for a time period of approximately 5 to 9 seconds.
