Abstract: An acrylic conductive paste is provided, based on 100 parts by weight, including: 30-84 parts of conductive particles, 15˜45 parts of acrylate, 0.5˜2.5 parts of adhesion promoter, 0.5˜3 parts of initiator. The conductive particles include three-dimensional dendritic conductive particles; and the adhesion promoter is a mixture of a silane coupling agent and a phosphate ester. The conductive paste of the present disclosure has good electrical conductivity, short curing time, strong adhesion, and can be used for a long-time room temperature operation. The present disclosure also provides a method for preparing the above-mentioned acrylic conductive paste, which is convenient for operation and industrial application; at the same time, it shows that the acrylic conductive paste of the present disclosure can be applied to semiconductor components for packaging a semiconductor device.

Abstract: This application provides a data processing method and device. The method includes: collecting a first image by using a camera; obtaining first point cloud data of the object based on the first image, where the first point cloud data indicates three-dimensional coordinate values of a surface point of the object in a first camera coordinate system of the first terminal; obtaining pose data of the first terminal in the first camera coordinate system based on the first image; obtaining a two-dimensional feature image based on the pose data, the first point cloud data, and the first image; generating map data based on the first point cloud data, the pose data, and the two-dimensional feature image; and sending the map data to a second terminal or a server.

Abstract: A streaming media processing method, device and system are disclosed in the embodiments of the present invention. The streaming media processing method includes: judging whether a transcoding is required according to the current bandwidth of a user terminal and a code rate of a pre-stored code stream, if yes, selecting a code stream of which the code rate is higher than the current bandwidth of the user terminal from the pre-stored code stream to perform the transcoding, and outputting the code stream matching the current bandwidth of the user terminal to the user terminal. The embodiments of the present invention enable the user terminal to obtain the streaming media of higher quality by effectively utilizing the bandwidth.
