    摘要： A wall mounted power supply receptacle device includes a body, a core disposed inside the body, and an insertion plate assembly. The body includes a upper body portion and a base connected to each other. The core includes a first circuit board assembly and a second circuit board assembly. The first circuit board assembly is accommodated inside the base and potted with a high thermal conductivity material. The insertion plate assembly includes insertion plates and wiring terminals and is mounted via a middle support frame above the first circuit board assembly. The second circuit board assembly is mounted via a grounding frame above the middle support frame. The grounding frame includes a U shaped notch that drops toward the base to accommodate the second circuit board assembly. The second circuit board assembly is electrically coupled to the first circuit board assembly through the wiring holes of the grounding frame.

    摘要： A wall mounted power supply device includes a housing, a transformer unit, including an input winding and at least one output winding; and at least one output circuit corresponding to the at least one output winding. Each output circuit includes: a rectifier unit, coupled to the output winding, to rectify a current of the output winding to generate a DC voltage signal; a DC-to-DC converter, to generate an output signal at an output connector based on the DC voltage signal. The transformer unit and the rectifier unit are sealed within the housing by a thermal adhesive to form a sealed integral unit with the housing. The device has a simple circuit design, is low cost and easy to install, and reliable.

    摘要： Examples of the present disclosure provide a method, an Instant Messaging (IM) client for transmitting multiple files, and an IM client for receiving multiple files. The method includes: receiving by an IM client one final request for transmitting N files to an IM user, wherein N is a positive integer, which is larger than or equal to 2; obtaining by the IM client the N files; adding, by the IM client, the N files to a transmitting process; and transmitting by the IM client the obtained N files, until all of the N files are transmitted. By employing the technical solution of the present disclosure, transmission of multiple files, such as, pictures, audios, videos, documents may be more convenient, and user experience may be improved.

    摘要： Methods and devices for managing and editing files in a file system are provided. In the method for managing data of a file in a file system, a storage space for storing the data of the file is divided into a plurality of blocks of identical size and sequentially numbered, wherein said blocks being organized in sequentially numbered chunks. And each chunk comprises at least one block. For a chunk, use first management data and second management data to record the size of space not occupied by data in the head part of the first block and in the end part of the last block of each chunk, subsequently to a deletion step of data within the file, the size of space being smaller than the size of a block.
