Abstract: A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.

Abstract: A lens module with enhanced absorption of stray light includes a sensor and a mounting bracket. The sensor includes a photosensitive area and a non-photosensitive area arranged surrounding the photosensitive area. The sensor is received in the mounting bracket and a window is defined in the mounting bracket. An annular flange extends from an inner wall of the window towards a center axis of the window. The annular flange includes a reflecting surface facing away from the inner wall of the window and tilted towards the sensor. The photosensitive area is exposed in a through hole of the annular flange. Diffusing reflection structures are formed on the reflecting surface and are configured to diffuse light incident on the non-photosensitive area away from the photosensitive area.

Abstract: An optical fiber cable includes a plurality of optical fibers arranged in juxtaposition with one another, and a plurality of adhesive materials spaced-apart disposed on the optical fibers. Each of the adhesive materials binds adjacent ones of the optical fibers to one another in a number that is smaller than a total number of the optical fibers. A method for manufacturing the optical fiber cable includes arranging the optical fibers in juxtaposition with one another, and applying the adhesive materials to the optical fibers in a spaced-apart manner, such that each of the adhesive materials binds adjacent ones of the optical fibers.

Abstract: The present invention relates to a linkage modularized LED display module including linkage lock unit. The said linkage lock unit is provided on the back of the bottom shell plate and includes a driving head and multiple linking rods. The driving head can drive the multiple linking rods to work simultaneously, so that the LED display module can be clamped in the assembly frame or different LED modules can be assembled together.

Abstract: The present invention discloses a coagulation analyzer and a coagulation analysis method which relate to the technical field of medical instruments. The coagulation analyzer includes an optical coagulation analysis module, a sample interference analysis module, a magnetic coagulation analysis module, and a test transfer module. The coagulation analyzer uses the sample interference analysis module to determine whether an interferent in the sample has effect on the coagulation test result of the optical coagulation analysis module. If the interferent in the sample has no effect on the coagulation test result, the optical coagulation analysis module is used to perform the coagulation analysis and report the test result. If the interferent in the sample has effect on the coagulation test result, the test transfer module is used to transfer the test to the magnetic coagulation analysis module to perform the coagulation analysis and report the test result.

Abstract: An intelligent device control method applied to an intelligent device, including the steps of: providing a mobile terminal configured to send a control instruction to the intelligent device, inputting the control instruction on the mobile terminal and converting the control instruction into an audio signal, sending the audio signal to the intelligent device, enabling the intelligent device to receive the audio signal, convert the audio signal to restore it to the control instruction, and read the control instruction, and executing a corresponding action according to the control instruction. The intelligent device control method is capable of making the transmission processes of control instructions simplified and efficient and improving the user experience. An intelligent device system is also disclosed.

Abstract: The present disclosure provides a network call method, terminal, and server. The method includes: displaying a scenario interface for a social application group; displaying a first list of user identifiers when an instruction for initiating a specified call is received; determining, according to a selection operation in the first list of user identifiers, identifiers of second users; sending a network call request to a social application server, the network call request comprising an identifier of the first user logging in at the first terminal locally and the identifiers of the second users, so that the social application server creates a virtual group, and adds, to the virtual group, the first terminal and second terminals corresponding to the identifiers of the second users accepting call invitations; and performing a network call in a call interface for the virtual group.

Abstract: This application belongs to the field of database application technologies, and discloses a data scrubbing method and apparatus. In the method, a server adds a share update exclusive lock to a target table, to prevent a system from performing a data definition language (DDL) operation on the target table. The server then creates a temporary table and a temporary index, copies data from the target table to the temporary table, and generates index information according to the data in the temporary table. Next, the server adds an access exclusive lock to the target table to prevent the system from performing a data manipulation language (DML) operation on the target table. Then data in the target table and the temporary table as well as corresponding index information is exchanged, thereby completing cleaning and reclaiming of disk space.

Abstract: A computing system for load processing obtains a current time and a reported load amount from an access machine at the current time and determines a delayed cognitive load amount allocated to the access machine at a first time period by subtracting a first time difference from the current time. Next the computing system determines an actual load amount of the access machine at the current time by adding the reported load amount and the delayed cognitive load amount and determines whether the access machine is running at an overload condition by comparing the actual load amount of the access machine at the current time and a maximum load amount threshold for the access machine. The present application can accurately determine the load amount that the access machine has received and schedule user terminals received by the access machine to prevent overloaded operation of the access machine.
