    摘要： A novel method to develop highly conductive functional materials which can effectively shield various electromagnetic effects (EMEs) and harmful radiations. Metallized nanotube polymer composites (MNPC) are composed of a lightweight polymer matrix, superstrong nanotubes (NT), and functional nanoparticle inclusions. MNPC is prepared by supercritical fluid infusion of various metal precursors (Au, Pt, Fe, and Ni salts), incorporated simultaneously or sequentially, into a solid NT-polymer composite followed by thermal reduction. The infused metal precursor tends to diffuse toward the nanotube surface preferentially as well as the surfaces of the NT-polymer matrix, and is reduced to form nanometer-scale metal particles or metal coatings. The conductivity of the MNPC increases with the metallization, which provides better shielding capabilities against various EMEs and radiations by reflecting and absorbing EM waves more efficiently. Furthermore, the supercritical fluid infusion process aids to improve the toughness of the composite films significantly regardless of the existence of metal.

    摘要： A train communication and control system is described having the cars of the train connected by a two-wire train line running continuously from car to car. Any car may be selected to be a master unit. The selection of one car as a master unit disconnects the power sources of all other cars from the train line, leaving the master unit power source as the sole power source for the line. The master unit communicates with each other car by causing a high voltage ("mark" state or logic one) or a low voltage ("space" state or logic zero) to be on the train line. Each non-master car can receive a communication from the master unit, or can transmit to another car by applying a low impendance across the train line to change from a "mark" state to a "space" state. The power source consists of a voltage regulator with precision constant current limit. Output voltage is maintained substantially constant until a load greater than the rated current limit causes the power source to change to a substantially constant current regulator, whereby its regulated voltage falls rapidly to the "space" state voltage.

    摘要： A sign-monitoring system includes at least one electronic sign and a controller comprising a processor and memory. The electronic sign includes a pixel array, the pixel array including a plurality of pixels. The electronic sign further includes an embedded controller coupled to the at least one electronic sign. The embedded controller develops diagnostic information for the at least one electronic sign, the diagnostic information including information related to a number of malfunctioning pixels in the plurality of pixels. The controller is communicably coupled to the embedded controller and receives at least a portion of the diagnostic information from the embedded controller. In addition, the controller assesses the at least a portion of the diagnostic information to develop health information. The assessment involves evaluating the information related to the number of malfunctioning pixels.

    摘要： A gallium-indium-zinc-copper metallic material has been found to exhibit many of the advantageous properties of mercury, such as electrical conductivity, fluidity, and high vaporization temperature. The metallic material is formulated by combining individual components in the presence of aqueous base, isolating the metallic phase, and heating the metallic combination. The metallic material is formulated to have sufficient quantities of each of the individual components such that the metallic material has a solidification temperature below 0.degree. C.

    摘要： A zero dead volume (ZDV) microbore high performance liquid chromatography (.mu.HPLC)/Fourier transform infrared (FTIR) interface flow cell includes an IR transparent crystal having a small diameter bore therein through which a sample liquid is passed. The interface flow cell further includes a metal holder in combination with a pair of inner, compressible seals for directly coupling the thus configured spectrometric flow cell to the outlet of a .mu.HPLC column end fitting to minimize the transfer volume of the effluents exiting the .mu.HPLC column which exhibit excellent flow characteristics due to the essentially unencumbered, open-flow design. The IR beam passes transverse to the sample flow through the circular bore within the IR transparent crystal, which is preferably comprised of potassium bromide (KBr) or calcium fluoride (CaF.sub.2), so as to minimize interference patterns and vignetting encountered in conventional parallel-plate IR cells. The long IR beam pathlength and lensing effect of the circular cross-section of the sample volume in combination with the refractive index differences between the solvent and the transparent crystal serve to focus the IR beam in enhancing sample detection sensitivity by an order of magnitude.
