    摘要： A system and a method for communicating video data associated with content across a network are disclosed. A server partitions the content into a plurality of tiles where each tile includes a subset of the content and index data describing a relationship between a tile and one or more adjacent tiles. Each tile is then encoded as a video frame, for example each tile is encoded according to the H.264 standard. The plurality of tiles are then transmitted to a client which combines the plurality of tiles using the index data to locally recreate the content. The client associates a predetermined viewport tile with a client viewport representing the area of the content that is visible in a client display device to allow viewing of the content while tiles not associated with the client viewport are cached to expedite subsequent retrieval.

    摘要： The present invention relates to an adjustable tripod mechanism to support devices/transducers for scientific measurements such as weather station, radio transceiver, acoustic modem, and the like. More particularly, this invention relates to a novel, fully mechanical, and hand-operated tripod stand that incorporates (1) capability for rigidly mounting devices such as instruments, transducers, and so forth on a desired plane at a desired height for measurement of a multiplicity of parameters (e.g., meteorological parameters such as wind speed and direction, solar radiation, air temperature, barometric pressure, humidity, and the like); (2) rotation of any attached/mounted-device/transducer in the azimuthal direction at any angular intervals to facilitate orienting a mounted device in a given direction without the need for rotation of the legs of the tripod; (3) capability for partitioning of the tripod into a multiplicity of desirable smaller segments, thereby enabling its trouble-free transportation to remote areas; (4) trouble-free coupling of a plurality of separate members to achieve the desired height for the tripod stand to suit a given installation environment; (5) improvement in the efficiency of assembly, de-assembly, and packing of the tripod system by rendering its members compact and dismountable; (6) achieving elegance in appearance and ease in mounting; (7) improvement in mechanical stability as a result of an adjustably wider base area; and (8) facility for locking the tripod mechanism to the floor to prevent its translational/angular movement under drag force induced by the prevailing wind.

    摘要： A new cellulose excipient, OCCAE, suitable for use as a binder, filler, and/or disintegrant in the development of solid dosage forms and as a bodying agent or a drug carrier in the preparation of topical formulations is described. The cellulose excipient is formed by reacting an oxidized cellulose ester with an alcohol in the presence of a catalyst. The invention also describes the formation of controlled release microspheres using OCCAE and/or oxidized cellulose esters that may be used to control the release of drug in a patient over a time period of several hours to several days.
