Abstract: The present application relates to the technical field of computers, and discloses a method and apparatus for generating a music file, and an electronic device and a storage medium. The method for generating a music file comprises: obtaining a first image; performing feature extraction on the first image to obtain a salient feature of the first image; mapping the salient feature to a musical instrument digital interface (MIDI) information coordinate system on the basis of the position of the salient feature in the first image, so as to determine MIDI information corresponding to the salient feature, the MIDI information coordinate system being used for indicating a correspondence between MIDI information and time; and generating a music file on the basis of the correspondence between the MIDI information and the time.

Abstract: The invention belongs to the field of bromine recovery from waste circuit board, and particularly relates to a method for recovering high-purity sodium bromide from bromine-containing crude salt. The invention mainly includes the steps of acidification oxidation, multi-stage extraction, and cooperative back extraction. Compared with traditional chlorine oxidation and single urea back extraction technology, the acidification oxidation process can be effectively controlled by reasonable adjustment of the added amount of hydrochloric acid and sodium chlorate, and the tail gas can be absorbed and reused to avoid secondary pollution and resource waste. At the same time, urea is used with sodium carbonate for cooperative back extraction to achieve a high back extraction rate which greatly reduces the amount of urea, and obtains high-purity sodium bromide crystals. The efficient recovery of bromine resources in bromine-containing crude salt is realised.

Abstract: Aspects for data transmission over wired networks are described herein. The aspects may include a first transceiver and a second transceiver respectively connected to a communication bus. When the first transceiver receives differential signals from the communication bus, the first transceiver may be configured to convert the differential signals to digital signals and further to transmit the digital signals to a configurable logic circuit connected to both the first transceiver and the second transceiver. The configurable logic circuit may be configured to transmit the digital signals to the second transceiver when the communication bus is idle. The second transceiver may be configured to convert the digital signals back to differential signals and transmit the differential signals back to the communication bus.

Abstract: The present disclosure provides a wire buffer device. The wire buffer device comprises: a frame; and multiple of support layers provided to the frame and arranged in layers. Each of the support layers includes multiple sections of wires that support a substrate. The multiple sections of wires are in the form of at least one integrated wire. The wire buffer device further includes at least one transmission structure. Said at least one transmission structure drives each of said at least one integrated wire to perform a reciprocating motion so that at least a part of each of said at least one integrated wire moves into or moves out from the frame. For the wire buffer device, work operability is improved, and secondary contamination to the device is avoided.
