Abstract: An embodiment of the present invention pertains to an apparatus and method for caching pixel data used in filtering edges of video macroblocks. Pixel data which are required to edge filter subsequent macroblocks are temporarily stored in a cache memory. When a macroblock is subsequently being processed, this cached pixel data is read out and used to filter the corresponding edge(s). By caching select pixel values rather than writing them to external memory, the number of memory accesses is dramatically reduced. ® KIPO & WIPO 2007

Title: Method for transmitting telecommunications data from an access network to a media gateway controller
Inventor: SCHMIDTKE UWE
IPC: H04L12/66
Filed: 2005-07-26
Abstract: The invention relates to a method for transmitting telecommunications data from an access network (AN) to a media gateway controller (MGC). According to said method, a TDM interface (V5.2) is located between an access network (AN) and a signalling gateway (SG) and an IP interface (IP) is located between the signalling gateway (SG) and the media gateway controller (MGC). Part of the telecommunications data, which is transmitted as layer 3 data in the uplink traffic for general, not directly traffic-relevant functions of the TDM interface (V5.2), is scheduled in the signalling gateway (SG). This eliminates the messages for general functions of the TDM interface on the IP side. Port control messages are thus only efficiently managed in the IP network in the accelerated port alignment mode, i.e. only data for a port group release method is transmitted, (for example, according to V5.2, amendment A1).

Title: Alleviation of non-specific binding in microarray assays
Inventor: FALCOVITZ GERASSI YEHUDIT
IPC: G01N33/543
Filed: 2005-08-11
Abstract: A post-incubation treatment is employed to effectively remove targets, such as proteins/protein complexes, or other label-bearing moieties that may non-specifically bind to a microarray substrate during a binding assay. Following incubation, a one-step wash is carried out with a liquid containing digester, e.g., a digestive enzyme (protease) or lysosome, which is effective to remove non-specifically bound targets or at least labeled portions of such targets from the substrate. Proteases are bound to or coated onto large molecules or onto solid particles of such a size such that they are prohibited from entering the porous surfaces of 3-D hydrogel microspots and are unable to reach and digest labeled target-probe complexes that are disposed within such porous hydrogel microspots. Digested segments of such protein which contain labels (or of essentially the entire protein) are carried away in the wash liquid and thus are not present to create background noise during imaging.

Title: Method and system for efficiently reducing graphical display data for transmission over a low bandwidth transport protocol mechanism
Inventor: COLEMAN PAUL
IPC: G06F17/30
Filed: 2001-05-29
Abstract: The present invention improves the performance of distributed systems by reducing the amount of graphical data transmitted betweenan application server and a thin client. The encoding technique used for graphical data is adapted in response to the repetitiveness of the graphical data during a particular client-server session. Indexes are maintained that are indicative of this repetitiveness and which identify a particular location in the client's cache memory storing the graphical data. Where the index is not found, but a fuzzy key indicates a strong likelihood that the graphical object is located at the client, the client's persistent storage memory is searched for a file name corresponding to the fuzzy key and which stores the graphical object therein. The invention also adapts the processing rate or encoding technique of the server in response to network changes or performance mismatches between the client and server.

Abstract: A novel aggregated-particle composition which can be recovered so as to be extremely reduced in the content of fine particles and coarse particles and satisfactory in powder characteristics including blocking resistance and powder flowability, without deteriorating the original quality possessed by the polymer itself, such as the effect of improving impact resistance. The aggregated-particle composition comprises: a graft polymer (A) comprising one or more flexible polymer phases and one or more rigid polymer phases, the outermost part thereof being the rigid polymer phase; a water-soluble polymer (B) having the property of forming a physical gel; and a gellant (C) therefor. The composition is characterized in that the amount of the water-soluble polymer (B) having the property of forming a physical gel is 0.01-3.0 parts by weight per 100 parts by weight of the graft polymer (A) and the proportion of the outermost rigid polymer phase in the graft polymer (A) is 0.5-10 wt.%.
