  • Patent number: 11065703
    Abstract: An emissions collection system that includes a containment system, the containment system including a plurality of walls and a roof structure that together form an internal chamber; wherein chamber inlets are formed in one wall of the plurality of walls; and wherein chamber outlets are formed in either another wall of the plurality of walls or the roof structure. A filter assembly includes a filter that collects emissions generated within the internal chamber; and a duct system that places the chamber outlets in fluid communication with the filter assembly; wherein the filter assembly is sized and configured to move air through the chamber inlets, the internal chamber, the chamber outlets, the duct system, and the filter to collect emissions generated within the internal chamber.

  • Publication number: 20130017974
    Abstract: Compositions and methods are provided for detecting genomic DNA gain and loss. Embodiments of inventive compositions and methods include composite nucleic acid probes which specifically hybridize to two or more genomic loci in a genomic region of a reference genome for detection of genomic gain and/or loss in a subject genome. In some embodiments, a substrate-attached composite nucleic acid probe is provided which includes a mixture of separate populations of beads having attached DNA probes wherein all of the beads are identically encoded and wherein each individual bead has exclusively DNA derived from one source, such as a particular large insert vector containing chromosomal DNA, or amplicons generated by amplification of DNA derived from a large insert vector containing chromosomal DNA.

  • Publication number: 20060252704
    Abstract: The present invention relates to crystalline polymorphs of 3-O-(3?,3?-dimethylsuccinyl)betulinic acid di-N-methyl-D-glucamine salt (“DSB•2NMG)”), pharmaceutical compositions of the same and use of the same as an active pharmaceutical agent in the treatment of HIV related disorders.

  • Publication number: 20060129922
    Abstract: A text enhancement method and apparatus for the presentation of text for improved human reading. The method includes extracting text specific attributes from machine readable text and varying the text presentation in accordance with the attributes. The preferred embodiment of the method: extracts parts of speech and punctuation from a sentence, applies folding rules which use the parts of speech to determine folding points, and presents text segments each on a new line and having a determined horizontal displacement based on the text specific attributes. One method displays text over bent curves having a shape based on text content. Another method includes displaying relative text position within a hierarchy using alternating vertically and horizontally tiled planes. Another method supports reading text segments across opposed pages without waiting for paging. Yet another method displays text to allow reading from bottom to top as though from front to back.

  • Publication number: 20020117042
    Abstract: An electronic virtual organ console is provided to be used in lieu of an actual organ console as a component of a church or theater organ. The present invention provides an interface between an electronic (MIDI) keyboard and the components of the organ that produce the sounds, or voices, of the organ. These components may be either those of a pipe organ or an electronic organ. The virtual console is operated been command inputs into a touch-sensitive screen monitor.

  • Patent number: 5580622
    Abstract: A structural element suitable for walls, tanks and bulkhead structures comprising opposed, axially extended surface structures and ribbing interposed therebetween in freely movable relation responsive to a temporary first relative dimensional condition of the surface structures and ribbing, and in blocking relation against separation of the surface structures responsive to a persistent second relative dimensional condition of the surface structures and ribbing.

  • Patent number: 5508085
    Abstract: A structural element core adapted to space apart opposed first and second, laterally and longitudinally extended, generally planar surface structures, the core comprising a closed figure pattern of ribbing defined by a plurality of periodically intersecting laterally or longitudinally disposed and vertically stacked fibers and a fiber supporting plastic matrix, the fibers and matrix being radially deflected at their locus of intersection with oppositely disposed fibers and matrix sufficiently to be vertically stacked to the same height at their locus of intersection as between. comprising opposed first and second. The core is usefully combined with one or more planar surface structures to form a structural element e.g., an aircraft panel.

  • Patent number: 5487930
    Abstract: A structural element comprising opposed first and second, laterally and longitudinally extended, generally planar surface structures each having a closed figure pattern of ribbing projecting therefrom toward the opposite surface structure, a third structure disposed between the first and second surface structures in ribbing-engaging relation therewith, the opposed ribbing being interlocked across the third structure in registered, mating relation.
