  • Patent number: 8412364
    Abstract: A method and a device for sending and playing the streaming data are disclosed in embodiments of the present invention. The method for playing the streaming data includes: receiving the streaming data from the client and buffering the data; and exporting the buffered streaming data according to the predefined rhythm. The statistics about the streaming data in the buffer is collected; and the rhythm is adjusted according to the amount of streaming data. The transmitting end can send the streaming data to the client as soon as possible and buffer only a little data; the client controls the rhythm to reduce the effect of network jitter on delay, thus shortening the delay of streaming play.

  • Publication number: 20100330027
    Abstract: The present invention is directed to curable compositions that comprise a non-porous substrate, one or more cyanoacrylate polymerization initiators and a prepolymer composition comprising at least one liquid cyanoacrylate monomer or mixture of such monomers (solid or liquid) and/or cyanoacrylate oligomers. The non-porous substrate is a collection of individual particulates that are not bound, bonded or fixed to one another. At least one initiator is deposited on the surface of the individual particulates to form a plurality of initiator carriers. The prepolymer composition receives the plurality of initiator carriers to begin a controlled and consistent polymerization or curing of the liquid cyanoacrylate monomer in order to produce a biocompatible adhesive composition for use on living tissue. The present invention also provides for methods of making and using and devices for such a curable compositions, particularly in treating living tissue by applying to living tissue a biocompatible adhesive composition.

  • Patent number: 7713544
    Abstract: A biocompatible biological component is provided comprising a membrane-mimetic surface film covering a substrate. Suitable substrates include hydrated substrates, e.g. hydrogels which may contain drugs for delivery to a patient through the membrane-mimetic film, or may be made up of cells, such as islet cells, for transplantation. The surface may present exposed bioactive molecules or moieties for binding to target molecules in vivo, for modulating host response when implanted into a patient (e.g. the surface may be antithrombogenic or antiinflammatory) and the surface may have pores of selected sizes to facilitate transport of substances therethrough. An optional hydrophilic cushion or spacer between the substrate and the membrane-mimetic surface allows transmembrane proteins to extend from the surface through the hydrophilic cushion, mimicking the structure of naturally-occurring cells.

  • Publication number: 20100051813
    Abstract: A measurement accessory with multiple transmission-reflections uses for an infrared spectrometer, laid accessory is arranged in the sample cavity of the infrared spectrometer. Said accessory includes two parallel plane mirrors (7, 8) and a sample holder fixed between the two mirrors (7, 8). Said sample holder can fix the sample piece (9) between the two plane mirrors (7, 8) and make the sample piece parallel with plane mirrors (7, 8). During measuring, the infrared ray emitted from infrared spectrometer (17) forms a certain angle incident to the space between said plane mirrors and reflects for several times between the two parallel plane mirrors (7, 8) and the sample piece (9) is measured with multiple transmission-reflections by the infrared spectrometer. Then the infrared spectrometer (20) enters into the detector of infrared spectrometer.

  • Publication number: 20090075283
    Abstract: The present invention relates to a shuttle BAC vector for facilitating the cloning, transfer and heterologous expression of streptomycete secondary metabolite biosynthetic gene clusters. The invention also relates to a plasmid rescue method using this vector for enhancing the process of cloning biosynthetic gene clusters for secondary metabolites from streptomycetes without sophisticated generation and screening of cosmids or BAC libraries. The cloned DNA can then be used for sequencing or heterologous expression of putative secondary metabolic gene clusters.
