  • Publication number: 20040121337
    Abstract: The present invention involves a series of articles, compositions, methods, and kits. Some aspects of the invention include articles such as particles, sols, blends, dispersions, films, or microarrays that comprise luminescent polymers, as well as methods for making and using such articles. In some cases, the luminescent polymer may be characterized in part by having a delocalized &pgr;-orbital structure, which can allow the polymer to have a high degree of luminosity. The polymers of this invention may also have, in some embodiments, bulky substituents to prevent intermolecular &pgr;-&pgr; interactions that can decrease luminosity. Some articles may include more than one luminescent polymer, for example, a first polymer that absorbs energy and directs the energy to a second polymer that releases the energy.

  • Patent number: 6661950
    Abstract: A novel tuned coupled-microresonator filter with a known transfer function. This transfer function may be used, along with the filter's output signal, to extract the original input signal. The quality factor of manufacturable microresonators typically exceeds 106 and permits the attainment of exceptionally high resolution in a small, physically-rugged, environmentally-protected package. In addition, the properties of the resonator and coupling optics lend themselves to low cost production.

  • Patent number: 6558626
    Abstract: A detector for detecting vapors emitted from energetic compounds includes a housing, a pump and a sensing assembly. The housing has an inlet, an outlet and an enclosed sensing volume there between. The pump communicates with the housing for moving a carrier gas sequentially through the enclosed sensing volume at a predetermined flow rate. The sensing assembly senses the vapors of the energetic compound delivered by the carrier gas as the carrier gas passes through the housing. The sensing assembly includes a sensing unit constructed of an amplifying fluorescent polymer, a source of excitation, a light detector, and a convertor assembly.
