20100287753 | DEVICE FOR MOLDING BISTABLE MAGNETIC ALLOY WIRE - A device for molding a bistable magnetic alloy wire having a feed reel, a feed roller, a furnace, a positioning roller, a receiving roller, and a receiving reel; a winch for passing the alloy wire through is disposed between the positioning roller and the receiving roller; the winch rotates around its axis; at least three wheels are distributed along the axis of the winch; the alloy wire passes an upper tangent point and a lower tangent point of an outer circle of the wheel; and the upper tangent point and the lower tangent point are disposed on the top and the bottom of the axis of the winch, respectively. | 11-18-2010 |
20110258294 | METHOD, APPARATUS, AND SYSTEM FOR PROCESSING MEDIA DATA - A media data processing method and apparatus are disclosed. The method includes: by a media server, receiving a play request which carries information of media content to be played; obtaining information of a related source server according to the information of the media content to be played and obtaining related media data from a locally stored media data segment; determining start time and/or end time of a media data segment to be obtained from the source server according to play time of the locally stored media data segment; and obtaining the media data segment from the source server according to the determined start time and/or end time of the media data segment. The invention prevents unnecessary transmission of media data and reduces the load of the server. | 10-20-2011 |
20110295779 | REGULAR EXPRESSION MATCHING METHOD AND SYSTEM - The present invention discloses a regex matching method and system, and relates to the field of computer technologies. The method includes: sorting multiple regexes into several regex groups, where all regexes in one regex group include a common string, which is known as a generic string; compiling each regex group into a DFA, and setting up a correlation between the generic string of each regex group and the DFA; matching to-be-matched data streams with the generic string respectively, and using the matched generic string as a matched string; obtaining a DFA corresponding to the matched string; and performing regex matching for the to-be-matched data streams according to the DFA, and outputting a matching result. The embodiments of the present invention shorten the data loading process, decrease the time consumed by data loading, and improve the matching performance. | 12-01-2011 |
20120102055 | REGULAR EXPRESSION MATCHING METHOD AND SYSTEM, AND SEARCHING DEVICE - A regular expression matching method and system, and a searching device are provided. First, the searching device performs string filtering on a data stream to be matched, in which if keywords in the data stream and preset character words have at least one same character, the searching device indicates that the data stream passes through the string filtering. Then the searching device performs regular expression filtering on the data stream passing through the string filtering. In a string filtering process through the method, system, and device, when Hash mapping positions of the keywords of the data stream are a subset of the Hash mapping positions of the character words, it indicates that the data stream passes through the string filtering, and it is not required to store the keywords and further compare the keywords with the character words, thereby saving the storage space and improving performance. | 04-26-2012 |
20130195117 | PARAMETER ACQUISITION METHOD AND DEVICE FOR GENERAL PROTOCOL PARSING AND GENERAL PROTOCOL PARSING METHOD AND DEVICE - The present disclosure provides a parameter acquisition method and device for general protocol parsing and a general protocol parsing method and device. The method includes: acquiring a message to be parsed; according to a preset state transition table, performing regular expression matching on the message to be parsed, and acquiring a state number and location information of a character corresponding to a matched matching rule; and acquiring the matching rule corresponding to the state number according to a preset rule matching table, and outputting a required field according to the matching rule, the location information, and the buffered message to be parsed, where the matching rule is an initial point sub-rule or an end point sub-rule. Embodiments of the present disclosure may implement general parsing on the protocol. | 08-01-2013 |
20130203888 | COPPER-FREE CERAMIC FRICTION MATERIAL AND PREPARATION METHOD THEREOF - The invention discloses a copper-free ceramic friction material and a preparation method thereof. The friction material at least contains the following materials in mass content: 2-30% of alkaline earth-based metal compound and 2-30% of carbon fiber, wherein the alkaline earth-based metal compound is M | 08-08-2013 |
20140068072 | METHOD, DEVICE, AND SYSTEM FOR ACQUIRING COST BETWEEN NODES - Embodiments of the present invention disclose a method, a device, and a system for obtaining a cost between nodes. The method includes: receiving, by a first server, a first cost request message from a client, where the first cost request message includes a first source node list, a first candidate node list, and a cost type; and calculating a cost between each source node in the first source node list and each candidate node in the first candidate node list according to the cost type. Network traffic management and optimization are implemented by using the technical solutions provided in the embodiments of the present invention, in which a cost between nodes is acquired from servers hierarchically deployed by an Internet service provider ISP and used as a basis of node selection. | 03-06-2014 |
20140317671 | METHOD AND SYSTEM FOR TRANSMITTING NETWORK VIDEO - Embodiments of the present invention disclose a method includes: sending, by a terminal device, video server name information in video request information to a local domain name server; receiving, by the terminal device, address information of a buffer sent by the local domain name server, and sending the video request information to the buffer according to the address information of the buffer; detecting whether a video resource corresponding to video identification information in the video request information exists in the buffer; and if the video resource corresponding to the video identification information exists in the buffer, sending, by the buffer, the video resource to the terminal device. The present invention is applicable to transmission of a network video resource. | 10-23-2014 |
