Abstract: A wearable sound device includes a venting module, configured to form at least one vent to connect a volume within the wearable sound device and ambient, and a sound producing device, configured to produce sound according to an equalized input signal. The venting module, including at least one venting device, operates among a plurality of statuses corresponding to a plurality of degrees of opening. A controller generates the equalized input signal according to a degree of opening among the plurality of degrees of opening, in order to counteract a roll off caused by the at least one vent.

Abstract: Disclosed is a pumping method of a large-diameter horizontal pressurized long dewatering well for inexhaustible pumping strata. Clay layers and sand soil layers are determined according to construction positions of foundation pits, horizontal holes are drilled in the sand soil layers with a drill rig with simultaneous casing, and after the designed depth is reached, horizontal wells are placed, the horizontal wells are located above the junction of the clay layers and the sand soil layers, and the horizontal wells comprise drain pipes and air ducts, the drain pipes and the air ducts are located at the same elevation, each air duct is located between the two drain pipes, and the air duct is connected with the air pipe of the air compressor to deliver and pressurize, so as to facilitate water in the strata of aquifer to gather into the drain pipes.

Abstract: The invention discloses a method for preparing an anticorrosive surface layer of a metal material in a marine environment by laser, which belongs to the technical field of laser processing. First, the laser cladding method is used to prepare a cladding surface layer on the surface of the metal material that is not easy to undergo chemical substitution reaction with the chlorides (NaCl, MgCl2 , CaCl2 etc.) in the seawater. Then, on the surface of the cladding surface layer, ultrafast laser processing is used to form a surface layer with a wetting angle (and water) greater than 90 degrees and with hydrophobic characteristics.

Abstract: Examples described herein relate to offload reliable transport management to a network interface device and store packets to be resent, based on received packet receipt acknowledgements (ACKs), into one or more kernel space queues that are also accessible in user space.

Abstract: The present invention relates to a CAD collaborative design system, for storing CAD files according to a timeline, and that facilitates restoration and review of versions created, modified, and updated at different times. The system stores the CAD files by means of summary files and incremental databases, thereby reducing data transmission volume, ensuring accuracy of file restoration, and improving the file management efficiency of the entire CAD system.

Abstract: The present invention discloses a method and a device for selecting an entity in a drawing, wherein the method includes that a hooked preview program corresponding to a functional instruction is invoked after the functional instruction is inputted into a Computer Aided Design (CAD) system; a pickup point in a drawing is selected; an entity in a predetermined range is filtered around the pickup point to obtain a preselected entity; the preselected entity is processed via the hooked preview program so as to pre-display a result of processing the preselected entity by the inputted instruction. An effect of a selected entity processed by a control instruction can be previewed according to the present invention, thus avoiding repeated selections of a graphic entity by a user to further improve working efficiency.

Abstract: A method for analyzing and classifying electronic documents. The method comprises steps of fetching an electronic document from an electronic document folder, wherein the electronic document comprises a plurality of key words. Then, the key words are retrieved. Further, according to an appearance frequency of each key word, a correlation between each two key words is calculated. Further, according to the correlations between the key words, the key words are classified into at least one technology group. Finally, the documents in the document folder are classified into at least one document group.

Abstract: An alloy and a gas turbine engine component comprising an alloy are presented, with the alloy comprising: palladium, in an amount ranging from about 1 atomic percent to about 41 atomic percent; platinum, in an amount that is dependent upon the amount of palladium, such that a. for the amount of palladium ranging from about 1 atomic percent to about 14 atomic percent, the platinum is present up to about an amount defined by the formula (40+X) atomic percent, wherein X is the amount in atomic percent of the palladium, and b. for the amount of palladium ranging from about 15 atomic percent up to about 41 atomic percent, the platinum is present in an amount up to about 54 atomic percent; and the balance comprising rhodium, wherein the rhodium is present in an amount of at least 24 atomic percent; wherein the alloy comprises a microstructure that is essentially free of L12-structured phase at a temperature greater than about 1000° C.

Abstract: A method of classifying documents is characterized by a process of assigning a title to an object document. The method is also characterized by a process of obtaining data representing the relationship between keywords and document titles. The former process features a mathematical operation between the data and the frequencies of keywords appearing in the object document, to obtain a group of reference numbers representing the relationship between the object document and the document titles, thereby at least one of the document titles is assigned to the object document according to the reference numbers. The latter process features mathematical operations on the frequencies of keywords appearing in the documents to which the document titles having been assigned, such as the documents in a historical record.

Abstract: A method for keyword correlation analysis is provided. The method obtains important words from a document repository, and then calculates correlations among the important words according to at least one of the occurring frequencies and occurring positions of the important words. Thereafter, keywords, which are highly correlated, can be obtained according to the correlations among the important words.

Abstract: This disclosure suggests a set of solutions to the bottle-necks in managing knowledge distribution/sharing. It is particularly powerful when applied to a system working with the Internet. Working together with keyword extraction rules, the solutions include a method/apparatus based on access authorization records related to issuers or providers of documents, categories of documents, crucial key words of documents, and feedbacks from authorized document receivers, for selecting at least an organizational unit (or person) to be an authorized unit (or person) having access to an object document. The art also features combining at least two of three access authorization records. Furthermore the art also features combining at least two of four sub-processes.
