The invention discloses a medal of a patent certificate. The medal is characterized in that a hanging fastener is arranged at the back of a medal body; a data interface is formed in the side of the medal body; the patent certificate and other information of the patent are stored in the medal body; colors and image-text for a cover of the paper patent certificate are shown on the front surface of the medal body; a pendant is connected below the medal body by a connection buckle; the medal of the patent certificate is applied for a state intellectual property office by an applicant; the medal is issued by the state intellectual property office; data stored by the medal body is recorded by the state intellectual property office in an encryption mode; and the applicant can update the data stored by the medal by virtue of a representative office of the state intellectual property office, connects the pedal of the patent certificate with a computer, inputs a password to read out contents by virtue of the computer and wears the medal on an important occasion, so that the medal is convenient to carry, a plurality of patent certificates and patent information are convenient to manage, the patent certificates and patent contents are convenient to display, the honor of the applicant and an inventor is improved, and the practicability is high.

The invention discloses a method for querying data in pages, which is suitable for execution in a distributed system, wherein the distributed system includes a database server, a cache server and an application server, the application server is suitable for receiving requests from clients, and the cache server is suitable for For obtaining data from the cache, the database server is suitable for obtaining data from the database, and the cache is preset with a data structure as the pagination key of the set collection. The method includes: obtaining the request parameter when the interface is called; generating the paging flag value based on the request parameter; obtaining the binary log of the database to determine whether the data in the database has changed; writing the paging flag value into the set corresponding to the paging flag key , and receive the return value, wherein, when the data in the database changes, the collection corresponding to the paging flag key is cleared so as to update the return value; and based on the return value, the query data is paged from the cache or the database.

A method for playing audio in game of mobile phone includes obtaining required sound and storing it in form of audio file, setting and storing a playing rule in advance, monitoring game action and seeking out stored audio file according to said playing rule, obtaining audio signal being able to be played out directly by decoding and decompressing audio file, carrying out convolution operation on audio signal to generate convolution signal being used to play out.

The method is suitable for the technical field of distributed systems. The invention provides a unique key generation method, device and terminal equipment, The method comprises the following steps of: Obtaining data to be generated, correspondingly generating a service instance code according to the service instance sequence of the to-be-generated data, correspondingly generating a year, a week,weekdays and a second according to actual time, correspondingly generating a serial number, an expansion bit and a version according to a preset rule, synthesizing the generated field into a unique key according to a unique key basic data structure, and labeling the unique key in the to-be-generated data; Wherein the generation field comprises service instance codes, years, weeks, weekdays and seconds, serial numbers, extension bits and versions. The method can ensure that the unique key data is not repeated in a single-machine scene, and meets the basic requirements of distributed global uniqueness, orderliness, inverse solvability, high performance, expandability, readability and the like.

The invention discloses a method and system for generating a unique identifier. The steps of the generating method include: a number issuer receives a registration identification factor request sent by a number taker and parameter information of the number taker, and records the parameters of the number taker information and send the identification factor to the number obtainer; the number obtainer receives the identification factor sent by the number sender, and the buffer unit of the number obtainer buffers the identification factor; the generation unit of the number obtainer obtains the identification factor from the buffer unit, and according to The identification factor generates a unique identifier. The design principle of the present invention is reliable and the structure is clear and definite, the double-buffer queue adopted ensures high availability, and the generated unique identifier does not depend on time, so it has the prospect of wide application.

The present application provides a generation method for a card number and an apparatus thereof. The method comprises: obtaining a request of a card number application request of a user; distributing the card number application request to one or more nodes, wherein each node has non-redundant number segment information; and obtaining corresponding basic card number information and a number segment value according to a received card number application request and corresponding number segment information through a node receiving the card number application request, and generating the card number according to corresponding basic card number information and the number segment value, wherein number segment values obtained that correspond to the same basic card number information are different. According to the generation method for card number provided by embodiment of the present application, different number segment values located in the number segment thereof are obtained in parallel through a plurality of nodes, and the card number, according to different number segment values and corresponding basic card number information, is generated, so that not only is the card number generated not redundant, but also the problem of performance bottleneck during a bulk card distribution is solved, thereby improving the efficiency of card distribution.
