摘要： An adhesive and method for attaching a heat sink to a printing wiring assembly that provides a thermal path from electronic components on the printing wiring assembly to the heat sink. The adhesive is flexible and accommodates thermal expansion stresses and is readily reworkable. The adhesive comprises a filler material that is disposed between the heat sink and the printing wiring assembly, and an impregnant that impregnates the filler material, which impregnated filler material is cured. The filler material may comprise alumina particles that have a spherical shape. The impregnant comprises a polymer, typically selected from a group of epoxy resins and their curatives that form a flexible material when cured. In practicing the method, a heat sink is positioned adjacent to and spaced apart from a printing wiring assembly to provide an appropriate spacing between them. The periphery of the printing wiring assembly is sealed. A cavity that is formed between the heat sink and the printing wiring assembly is filled with a filler material. The filled assembly is vibrated to maximize packing density of the filler material. The filler material is then impregnated with a flexible epoxy impregnant. The impregnant is then cured to form the flexible adhesive. This produces a structure wherein the heat sink is bonded to the printed wiring assembly.

摘要： Methods and apparatus are provided for an interconnect system for coupling radio frequency signals from one component to another in a RF system. The interconnect system acts as a coaxial connection. The apparatus comprises an interconnect, a dielectric sleeve, and a conductive elastomeric gasket. The interconnect has a first major surface and second major surface for providing an electrical connection. A through hole is formed in a first component. The dielectric sleeve is placed in the through hole. The interconnect is placed in the dielectric sleeve. The conductive elastomeric gasket is placed in proximity to the through hole contacting the first component and a second component. The RF system is assembled compressing the elastomeric gasket to have intimate contact with the first and second component. The intimate contact electrically connects the first and second component and an electric shield is formed around the interconnect thereby suppressing the reception and transmission of RF signals.

摘要： A blue-sensitive radiographic silver halide film comprises a silver halide emulsion layer comprising predominantly tabular silver halide grains that have an aspect ratio of at least 15, a grain thickness of at least 0.1 &mgr;m, and comprise at least 90 mol % bromide and up to 4 mol % iodide, based on total silver halide. Substantially all of the iodide is present in an internal localized portion of the tabular silver halide grains that excludes the surface of the grains. The tabular silver halide grains are dispersed in a hydrophilic polymeric vehicle mixture comprising at least 0.5% of oxidized gelatin, based on the total dry weight of the polymeric vehicle mixture in the emulsion layer. The tabular silver halide grains are spectrally sensitized using a combination of spectral sensitizing dyes to provide increased speed and reduced dye stain. The dyes have maximum J-aggregate absorptions on the tabular silver halide grains of from about 380 to about 500 nm, wherein the maximum J-aggregate absorption of one spectral sensitizing dye is from about 20 to about 50 nm lower in wavelength than the maximum J-aggregate absorption of the second spectral sensitizing dye.

摘要： A method and device for detecting and/or photographing unregulated light flash events such as lighting strikes and muzzle flashes during both daylight and night time conditions is disclosed. The present device utilizes a photodiode sensor in conjunction with a photoresistor to control feedback gain of a transimpedance amplifier thereby providing non-linear amplification and therein constant sensitivity to detect an unregulated, omni-directional flash of light and produce an output signal that is input to an analog comparator circuit whereat a predetermined threshold level is set to prevent false triggering of the isolation relays and/or camera shutter. The output from the comparator circuit is input to a timer circuit to produce a signal of sufficient duration to trigger the isolation relay(s) and/or camera shutter. The output signal from the timer circuit is sent to an isolation relays and/or an infrared coded pulse generator depending on the features of the particular associated equipment in order to release the camera shutter or to protect an electronic or electrical device from the damaging effects of the lightning return stroke. In an alternative embodiment the functions of the comparator circuit, the timer circuit and the coded pulse generator are carried out by a programmable logic device such as a mixed signal processor with analog, digital, real time clock and non-volatile RAM capability wherein the lightning event processing functions are incorporated into the program code. In a further embodiment, the coupling circuit is tuned wherein motion of an object is detected. In yet a further embodiment, multiple photosensor arrays are utilized in conjunction with non-linear amplification and computing means to determine the location of flash events and to control associated equipment.
