Abstract: Interconnect feed devices (10) are provided for electrically connecting first and second electrical components (17, 21). The interconnect feed devices (10) can include a dielectric shell (23) with an electrically-conductive coating (40), and leads (22) positioned within individual conduits (30) of the shell. Each lead (22) and its associated conduit (30) can act as a coaxial cable for transmitting radio frequency (RF) energy between the first and second electrical components (17, 21). The shell (23) can be manufactured using a process, such as stereolithography, that allows the shell to be formed with relatively complicated geometries, which in turn can facilitate relatively complicated cable routing.

Abstract: A method of packing and transporting televisions includes placing a television into a protective box in a manufacturing district, in which the television is produced. The television and the protective box are transferred from the manufacturing district to a delivery address. The television is taken out of the protective box and is set-up at the delivery address. The protective box is transferred from the delivery address back to the manufacturing district, and is used to pack and transfer another television.

Abstract: A circuit card clamp (300) including a base member (316), at least one first wedge member (446), and a thermally conductive membrane (350). The base member has an elongated shape configured for insertion in a circuit card chassis slot (106). The first wedge member is movable relative to the base member in response to a first actuator (304) for engaging the circuit card chassis slot. The thermally conductive membrane is coupled to the base member and the first wedge member. The thermally conductive membrane has slack for permitting the first wedge member to move relative to the base member between a first clamped position and a second unclamped position. The thermally conductive membrane defines a thermal conductive path (206) between a circuit card (104) and the chassis slot for releasably securing a circuit card in the circuit card chassis slot.

A circuit unit and an insulation layer are provided, and the insulation layer is set between the circuit unit and the conductive layer. The conductive layer, the circuit unit and the insulation layer are laminated. The passive component material layer is between the insulation layer and the conductive layer. The conductive layer is patterned to form a circuit layer.

Abstract: A cam activated circuit card clamp is provided. The circuit card clamp is comprised of a base member (204), a leverage arm (412), and a cam activation shaft (422). The circuit card clamp is also comprised of one or more cams (410-1, 410-2, 410-3, 410-4), one or more ramp members (308-1, 308-2, 308-3, 308-4), and one or more wedge members (418-1, 418-2, 418-3, 418-4). The cam activation shaft is coupled to the leverage arm. The cams are in contact with the cam activation shaft which has one or more compression springs disposed thereon. The cams are adapted to pivot about a pivot shaft when actuated. The cams also have a surface adapted to engage an adjacent wedge member when actuated. Each ramp member has an inclined surface adapted to deflect an adjacent wedge member when the adjacent wedge member is compressed against the ramp member. Each wedge member has a surface adapted to engage an adjacent cam.

Abstract: System for dynamically tracking a position of a target with an antenna in a communication system. The system includes an antenna system (410) configured for generating a sum and difference antenna pattern (201-1, 201-2). A sum RF channel (401) is coupled to a sum channel output of the antenna system. A difference RF channel (402) is coupled to a difference channel output of the antenna system. An RF coupler (422-1) is provided that has a first input coupled to the sum RF channel and a second input coupled to the RF difference channel. One or more coupling control devices (418-1, 418-2) selectively vary an effective coupling value as between the difference channel and the sum channel. An antenna tracking error signal is generated at an output of the coupler.

Abstract: A ruggedized, snap-together, module securely retains a pair of mutually abutting fiber optic interconnect MT ferrules, that have been joined together by a ferrule aligning pin clamp structure. The module includes a generally rectangular base member having a ferrule retention cavity that is configured to retain a pair of MT ferrules and an associated pin clamp assembly therefor. A cover is configured to engage the base in such a manner that the two MT ferrules are firmly held in their intended face-to-face abutting condition as captured between the base and the cover. A bias compression spring is captured between the cover and the base in a manner that facilitates removal of the cover when it is desired to open the module and gain access to the two MT ferrules.

Abstract: A metal spray apparatus is provided with a supersonic nozzle. Molten metal is injected into a gas stream flowing through the nozzle under pressure. By varying the pressure of the injected metal, the droplet can be made in various selected sizes with each selected size having a high degree of size uniformity. A unique one piece graphite heater provides easily controlled uniformity of temperature in the nozzle and an attached tundish which holds the pressurized molten metal. A unique U-shaped gas heater provides extremely hot inlet gas temperatures to the nozzle. A particularly useful application of the spray apparatus is coating of threads of a fastener with a shape memory alloy. This permits a fastener to be easily inserted and removed but provides for a secure locking of the fastener in high temperature environments.
