Abstract: This invention discloses a wave field reconstruction method via optical perception, including: (1) building a data platform for a virtual wave field; (2) pre-training a domain converter module using color image data of the virtual wave field and real water surface image data captured by a camera; (3) pre-training a depth estimation module using generated paired color image data and depth image data of the virtual wave field; (4) converting the style of a real water surface image into a virtual-water-surface-style image via the domain converter module; (5) outputting the virtual-water-surface-style image as a depth image with the same style and recording the distance between a wave surface sampling point and the camera's optical center; and (6) generating surface point cloud data of a water surface wave field with the camera's optical center as the coordinate origin. The method enables real-time, robust wave field depth reconstruction, ensuring reliability and authenticity.

Abstract: The present invention relates to negative electrode carbon materials for lithium-ion batteries, and particularly to a lithium-ion battery negative electrode active material, a lithium-ion battery negative electrode, a lithium-ion battery, a battery pack and a battery-powered vehicle. In a pore structure, measured by N2 adsorption and desorption, of the lithium-ion battery negative electrode carbon particles, by using the total pore volume measured by BJH having a pore size of 2-200 nm as the reference, the sum of the volumes of pores with a pore size of 2-10 nm is 2-10%, the sum of the volumes of pores with a pore size of 10-100 nm is 30-65%, and the sum of the volumes of pores with a pore size of 100-200 nm is 30-65%, and the carbon particles have a BET specific surface area of 0.9-1.9 m2/g.

Abstract: A method for managing the reading of a barcode and deactivation of an EAS tag relative to an EAS effective range and a depth of field (DoF) of the scanner is described. A product may comprise a barcode and a co-located EAS tag. The method uses a distance sensing system to sense how far the product is located from the scanner front window. The method only outputs the decoded data of the barcode when the product is inside an EAS effective distance. When the product is inside the EAs effective distance, the EAS tag on the product is deactivated. When a customer leaves a store with the EAS tag deactivated, a store alarm may not sound. When the product is outside of the EAS effective distance, but inside the DoF, the decoded data of the barcode is discarded.

Abstract: An imaging scanner is provided. The image scanner has a housing. The housing contains a mirror, a camera, a transparent window for scanning, a transparent window for viewing positioned above the transparent window for scanning such that anything presented below the transparent window for scanning is visible in the transparent window for viewing. The transparent window for viewing has an electronic display embedded therein. The imaging scanner also includes an image decoder linked to the camera and to the electronic display. The mirror is positioned such that incident light on the mirror from the transparent scanning window will be reflected within the camera's field of view. The camera is configured to scan images presented at the transparent window for scanning. The image decoder is configured to decode the scanned images. The electronic display is configured to display the decoded information on the transparent window for viewing.
