Abstract: Disclosed is a high-voltage shielded connector assembly. The technical problem to be solved is that existing high-voltage connectors are large in volume, complex to assemble and machine, non-universal, and high in cost. The present invention comprises a socket protection sleeve body, a pin, a socket shielding layer fixed on the socket protection sleeve body and a fixing clip fixing the socket shielding layer, wherein the pin cooperates with the socket protection sleeve body; and the pin comprises a two-layer locking structure formed by a main locking structure and an auxiliary locking structure. After using the above-mentioned technical solution, the present invention uses a high-voltage large-current plate-end shielded connector which is made of plastic and is suitable for new energy automobiles, is low in cost, has high production efficiency, is small in volume, and is simple in wiring harness assembly and processing.

Abstract: Disclosed are systems and methods for improving interactions with and between computers in content communicating, rendering, generating, hosting and/or providing systems supported by or configured with computing devices, servers and/or platforms. The systems interact to improve the quality of data used in processing interactions between or among processors in such systems for determining obscured portions of displayed digital content. The disclosed method and apparatus involve acquiring and recording coordinates of each pixel in a digital image, and marking the pixels located at a boundary of the image as boundary pixels. The pixels located at a first region block are extracted and marked as obstruction pixels. An obstructed cutting space area corresponding to each pixel is determined based on positional relations of each pixel in the image. An image obstruction score is calculated based on the cutting space areas and utilized for rendering the pixels of the image.

Abstract: The disclosure describes a grading method and device for digital image quality. The method comprises: obtaining a digital image and extracting n main body region blocks from the image; calculating a first ratio value of the area of a plurality of main body region blocks to the total area of the image, a second ratio value of the area of background region blocks to the total area of the image, and a normalized distance value from a plurality of the pixel points in the plurality of main body region blocks to a center pixel point of the image; calculating to obtain a quality score value of the image through a preset digital image quality score conversion relation based on the first ratio value, the second ratio value, and the normalized distance value; and grading a quality of image according to a quality score value of the image and a preset digital image quality score threshold value.
