Abstract: Systems and methods for reducing multicast IP packet bandwidth in a local area network carrying Internet protocol television (IPTV) traffic are disclosed. One embodiment of a system comprises: a layer-2 switch; a slave digital home communication terminal (DHCT); and a master DHCT. The layer-2 switch has a control channel and a plurality of data ports. The slave DHCT is coupled to a first data port of the plurality. The master DHCT is coupled to the layer-2 switch control channel. The master DHCT comprises logic for requesting the layer-2 switch, over the control channel, operate in a first configuration. In the first configuration, the layer-2 switch associates a layer-2 multicast address with the first data port, examines layer-2 multicast packets, and forwards the examined layer-2 multicast packets on the first data port only if the layer-2 destination address is the first layer-2 multicast address.

Abstract: A method and system for assisting mobile stations to locate a satellite use an efficient messaging format. A server computes a correction between coarse orbit data of a satellite and precise orbit data of the satellite. A coordinate system is chosen such that variation of the correction is substantially smooth over time. The server further approximates the correction with mathematical functions to reduce the number of bits necessary for transmission to a mobile station. The mobile station, upon receiving the coefficients, evaluates the mathematical functions using the coefficients and a time of applicability (e.g., the current time), converts the evaluated result to a standard coordinate system, and applies the conversion result to the coarse orbit data to obtain the precise orbit data.

Abstract: Solid Oligosaccharides and Polysaccharides (SOP) are obtained from tissues of plants through the basic SOP process. A batch consisting of small pieces of plant tissue is soaked in alkaline solution at ambient temperature and pressure in a pulp-mill batch digester or similar extraction vessel. The alkaline extract is separated from the insoluble residue in the extraction vessel and transferred as clear solution to a SOP-forming tank, and the insoluble residue of plant tissue remaining in the extraction vessel is soaked in a second volume of alkaline solution. That second volume of alkaline extract is also transferred to a SOP-forming tank, whereupon the insoluble residue remaining in the extraction vessel is processed into pulp and paper or other products using established methods. SOP is produced in the SOP-forming tank as a coagulated suspension by adding to a volume of alkaline extract an equal volume of an aliphatic alcohol and mixing the two. SOP is concentrated, bleached and/or washed then dehydrated in a SOP separator. Alcohol used in the process is recovered by distillation, and the residual alkaline solution is adjusted to the desired concentration by addition of alkali then returned to the extraction vessel for treatment of another batch of plant tissue pieces. Potential uses of SOP are multi-faceted, e.g., as digestive fibre, foodstuff (e.g., syrup, sweetener), gum, paper additive, bulking agent in pharmacy or well-drilling, and as soluble carbohydrate for production of alcohol through fermentation or for other purposes including energy production.

Abstract: In a method for logging the location of a fluid depth (13) in a wellbore (10), an acoustic event is allowed to take place in a specific manner at the ground surface (11). This acoustic event generates pressure waves. The pressure waves travel in the wellbore (10) downward. The pressure waves traveling in the wellbore (10) are reflected at least also at the fluid depth (13). At the ground surface (11), the pressure waves traveling there out of the wellbore (10) are picked up and the time of travel since the acoustic event is measured. The picked-up and measured pressure waves are analyzed and, together with the associated time of travel, the location of the fluid depth (13) is deduced. The acoustic event generates a signal pattern (42) having a predetermined, time-variable frequency spectrum. The signal pattern (42) is emitted as vibration event into the wellbore (10), travels downward, and is reflected. At the ground surface (11), the picked-up signals originating from the wellbore (10) are analyzed. During the analysis, vibration events that do not correlate with the emitted signal pattern (42) are filtered out. From the vibration events (43) that are among the picked-up signals and correlate with the emitted signal pattern (42) and from the time of travel since the radiation of the signal pattern (42), the location of the fluid depth (13) is deduced.
