Abstract:
An LED array is thermally coupled to a heat spreader and a heat sink. The heat sink has a base and a plurality of fins extending from the base. Each fin includes a lower portion which extends outwardly from the base and downwardly from the heat spreader, and an upper portion that extends upwardly from the base and is offset from the lower portion so as to form a junction. An aperture may be provided through each junction to allow air to pass therethrough. The heat spreader may also have fins.
Abstract:
A light module system includes a receptacle, which may be mounted on a support surface, such as a heat sink, and further includes a cover and an LED assembly rotateably coupled to the cover. The LED assembly seats within the receptacle which causes terminals of the LED assembly to align with contacts on the receptacle. One of the cover and the receptacle has a plurality of ramps and the other has a plurality of shoulders. The cover can be rotated relative to the receptacle to cause the shoulders to slide relative to the ramps so as to direct the LED assembly into the receptacle. When the LED assembly is attached to the receptacle, the terminals on the LED assembly mate with the contacts on the receptacle.
Abstract:
An LED array is mounted on a base that is thermally coupled to a heat spreader. At least one aperture is provided between the support area and an edge of the heat spreader. The heat spreader may be coupled to a thermal pad which has sufficient thermal conductivity and is sufficiently thin to allow the thermal resistivity between the heat spreader and a corresponding heat sink to be below a predetermined value.
Abstract:
An assembly (118) is provided for mating a sensor (22) to a connector (24). The assembly includes an interconnect device (20, 120) and a housing (174a-174b). The interconnect device has conductive pathways (40, 154) provided thereon. The sensor is mounted on the interconnect device and is in electrical communication with the conductive pathways. The housing generally surrounds a portion of said interconnect device. The housing is formed of two portions which mate together. At least one flow tube (178) is attached to the housing. A gasket seals the sensor to the housing.
Abstract:
A transmission line for high-frequency differential signals and having a transforming impedance is formed into a substrate. The transmission line is comprised of a slot, the opposing surfaces of which carry a conductive surface capable of carrying electrical signals. The conductive surface on the opposing surfaces is gradually receded along a length of the slot. An equivalent amount of metallization is applied on the substrate's surface and electrically continuous with conductive surfaces on the slot's opposing sidewalls. The metallization on the substrate's surface provide solder lands. Dielectric in the slot prevents solder wicking.
Abstract:
An electro-magnetically shielded slot-transmission line is formed by metallizing the opposing sides of a slot cut through a dielectric substrate. A ground plane is deposited on the bottom of the substrate. Conductive vias through the substrate and that contact the ground plane are located on both sides of the metallized slot surfaces. Conductive pads on the upper surface and which contact the vias provide additional shielding.
Abstract:
A pedestal connector that incorporates one or more grouped element channel link transmission lines is seen to have a dielectric body and two opposing contact ends that are intended to contact opposing contacts or traces. The dielectric body has an S-shaped configuration such that the transmission lines supported thereon make at least one change in direction, thereby permitting the use of such connector to interconnect elements lying in two different planes. The transmission lines include slots that extend within the frame and which define opposing, conductive surfaces formed on the dielectric body which are separated by an intervening air gap.
Abstract:
A modular system is provided for arranging a plurality of electrical connector assemblies in a stacked array. The system includes at least a pair of electrical connector assemblies stackable one on top of another. Each assembly includes a frame structure having input and output faces, with an interior cavity between the faces. Input and output connectors are respectively mounted at the input and output end faces and project outwardly therefrom. A circuit board is located in the interior cavity and is electrically connected between the input and output connectors. A pair of end flanges project outwardly from at least one of the input and output end faces above and below the respective input or output connector to protect the respective connector. The end flanges have fastening portions to facilitate holding the frame structures and, thereby, the electrical connector assemblies in the stacked array. Electrical connectors also are coupled between the circuit boards of the stacked connector assemblies through the frame structures thereof.
