    摘要: A computed tomography (CT) image quality phantom for use in calibrating explosive detection systems (EDS) at airports. A foam core block containing up to five right cylinder rod members is positioned in a housing member which is adapted to be passed through an airport luggage scanning machine. The rod members are of different lengths in order to create different data slices for analysis. The housing has a lead-in member at least at one end in order to allow passage through an EDS more easily and provide accurate CT calibrating.

    摘要: A method and apparatus for identifying and tagging a target, such an individual or an item, are described that provide an improved mechanism for identifying the target without alerting the target. In this regard, a method and apparatus can irradiate the target so as to create a radioisotope signature for the target. By thereafter monitoring the radioisotope signature, the target can be identified and tracked in a covert manner.

    摘要: A light extraction film having multi-periodic zones of engineered nanostructures. The light extraction film includes a flexible substrate, a layer of low index engineered nanostructures applied to the substrate, and a high index backfill layer applied over the nanostructures. The multi-periodic zones include a repeating zone of the nanostructures having multi-periodic characteristics. The repeating zone includes first and second sets of nanostructures having different periodic pitches. The multi-periodic zones can be used to enhance the light output and tune the angular luminosity of organic light emitting diode devices.

    摘要: Compositions comprising a plurality of carbon nanotubes, a host polymer, and A block copolymer comprising a first block and a second block, wherein no block is compatible with the host polymer. In one aspect, the block copolymer is amphiphilic. In another aspect, the block copolymer may comprise a first block and a second block, wherein at least one of the first and second blocks comprises repeating units derived from a monomer having the general formula: (R)2C═C(R)(Rf) wherein Rf is selected from fluorine, a C1 to C10 fluorinated or perfluorinated alkyl group, and a C1 to C10 fluorinated or perfluorinated alkoxy group; each R is independently selected from F, H, Cl, Rf, a C1 to C10 alkyl group, and R2A, wherein R2 is a C1 to C10 alkylene group and A is selected from CO2M and SO3M, wherein M is selected from H, an ammonium and organo onium group.
