Abstract: The present invention relates to the field of coal mine underground auxiliary transportation equipment, and particularly relates to an overhead monorail driving unit group realizing mechanical fast power distribution. The overhead monorail driving unit group realizing mechanical fast power distribution includes a rail, wherein the rail is connected with driving portions, carrying trolleys and a hoisting beam, the hoisting beam is disposed in a middle position of the driving portions and the carrying trolleys, and the driving portions, the carrying trolleys and the hoisting beam are connected through driving portion short pull rods, frame-shaped pull rods and driving portion long pull rods.

Abstract: The invention presents a near-infrared photothermal coupling curing non-oxide ceramic slurry, along with its preparation method and application. The ceramic slurry consists of various raw materials, with weight fractions as follows: non-oxide ceramic powder (40˜90 parts), photosensitive resin (0.5˜20 parts), photosensitive monomer (1˜40 parts), photoinitiator (0.25˜4 parts), thermal initiator (0.25˜4 parts), additive (0.75˜5 parts), and up-conversion luminescent material (0.5˜4 parts). The non-oxide ceramic powders can include Si3N4, TiN, BN, AlN, SiC, WC, TiC, ZrC, TiB2, and ZrB2. By combining the photochemical and photothermal dual curing system using near-infrared up-conversion, this invention addresses the issue of insufficient curing encountered in single photocuring or thermal curing processes.

Abstract: A method for playing media data is disclosed, including: transmitting, by a first operating system, a request for processing the media data to a second operating system, the first operating system and the second operating system being installed on a same device; receiving, by the first operating system, processing results from the second operating system, wherein the second operating system is configured to process the media data based at least in part on the request to generate the processing results; and playing the media data by the first operating system based at least in part on the processing results.

Abstract: Playing multimedia data including instructing that a transparent area be painted in a first drawing layer, instructing that a multimedia data playing window be painted in a second drawing layer, the multimedia data playing window overlapping with the transparent area, instructing synchronous display of the transparent area and the playing window, and instructing that the multimedia data be played in the playing window.
