A method of summarizing a document includes a step of extracting one or more sections of the document. The method also includes a step of separating at least one of the one or more extracted sections into one or more subsections based at least in part on a conjunctive structure of the section, wherein each subsection comprises one or more terms. The method also includes steps of determining whether one or more terms within a designated set of terms are present within at least one of the one or more subsections and, responsive to a determination that one or more terms within the designated set of terms are present within at least one of the one or more subsections, removing the one or more terms from the one or more subsections. The method also includes a step of aggregating at least a portion of the one or more sections into a summary of the document.

Disclosed is a method of identifying partnering potential by: assembling a set of target patents representative of an industry of interest; building a dictionary of text feature entries; generating a set of text feature clusters; creating one or more contingency tables for assignees; and deriving an indication of partnering potential between the first assignee and the second assignee by comparing the values for each category for each assignee in each contingency table.
摘要:
The invention relates to a process for the production of chloramine comprising supplying a first reagent stream comprising chlorine gas and a second reagent stream comprising ammonia gas to a reaction zone maintained at a temperature of less than 275° C. and configured to allow expansion of the first and second reagent streams in the reaction zone to an extent sufficient to generate chloramine as a gas and ammonium chloride as a free falling solid. The invention also provides a chemical reactor suitable fur operating this process.

A spreader (216) comprises a code generator (301) and exclusive OR circuitry (303). In the preferred embodiment of the present invention the code generator (301) generates a code having a length and value dependent upon the current transmission rate. This code is then exclusive OR'd with the incoming data stream to produce spread data.

摘要:
The present invention relates to a reactor comprising a plurality of reaction zones, a first reaction zone being configured to provide a first residence time for a reaction mixture passing therethrough at a particular flow rate, and a second reaction zone connected in series with the first reaction zone and configured to provide a second residence time for the reaction mixture passing therethrough at the particular flow rate, wherein the second residence time is at least about 1.5 times greater than the first residence time, the reactor further comprising means for bypassing at least one of the first and second reaction zones to reduce the effective residence time of the reaction mixture passing through the reactor.

A wireless communications system and methods therein uses information, such as frame sequence numbers to improve DCCH or SCH power control. The system includes a base transceiver station (BTS) (14) with a frame type determinator (32) for determining whether the recovered data frames are good, erased, or non-transmitted data frames. A selector distribution unit (SDU) (16) includes a frame type verification processing block (36) for verifying that the frame type determinations made by the frame type determinator are correct based on the sequence numbers from received good data frames, and a power control block (38) for transmitting subscriber device power control information based on frame type determination verifications made by the verification processing block.
摘要:
Upon receiving (101) a vocoded voice frame and detecting (102) that the received vocoded voice frame comprises an erased frame, one automatically replaces (103) the erased frame with a valid frame having at least one error condition. In a preferred approach this error condition is one that is known to cause a receiving target platform to invoke a corresponding erasure process with respect to the valid frame when received.

A communication system provides a clear channel link for transport of encrypted payload across a network of the communication system. When a source access network receives, via an air interface, a frame that is formatted pursuant to an air interface protocol and that comprises encrypted payload, the source access network demultiplexes the frame to separate the encrypted payload and assembles an Intersystem Link Protocol (ISLP) frame that comprises the encrypted payload. The source access network adds a link layer header to the ISLP frame that identifies one or more of frame type information and a sequence value associated with the frame and conveys the ISLP frame and added header across the network, for example, to a destination access network. Based on the added header, the source and destination access networks are able to perform clear channel synchronization.
摘要:
The present invention relates to a continuous process for the enantioselective catalytic hydrogenation of β-ketoesters comprising providing a catalytic hydrogenation zone and maintaining it under conditions of temperature and pressure effective for the catalytic hydrogenation of β-ketoesters; continuously supplying to the catalytic hydrogenation zone a substrate comprising a β-ketoester to be hydrogenated, a catalyst effective for enantioselective hydrogenation of the β-ketoester and hydrogen; contacting the substrate, the catalyst and the hydrogen in the hydrogenation zone for a residence time effective for at least partial enantioselective catalytic hydrogenation of the β-ketoester; (d) continuously withdrawing from the hydrogenation zone a reaction product mixture comprising enantioselectively hydrogenated β-ketoester, unreacted β-ketoester, catalyst and hydrogen; (e) supplying the reaction product mixture to a separation zone and separating at least some of the enantioselectively hydrogenated β-ketoester from the reaction product mixture; (f) withdrawing the separated enantioselectively hydrogenated β-ketoester as product; and (g) optionally supplying at least part of the remaining material from the separation zone to the hydrogenation zone.
