Patent number: 11042777Abstract: The present disclosure provides a classification method and a classification device of an indoor scene. The classification method includes steps: receiving an input scene picture to be classified; obtaining a current local observation area from the scene picture to be classified according to a observation area positioning model; processing image information of the current local observation area to obtain a feature vector; obtaining a classification prediction result according to the feature vector; determining Whether the classification prediction result satisfies a predetermined scene picture classification condition; if not, obtaining a next local observation area from the scene picture to be classified and setting the next local observation area to be the current local observation area, then skipping to the step of processing the image information of the current local observation area; if yes, obtaining a classification label of the scene picture to be classified.Type: GrantFiled: March 27, 2017Date of Patent: June 22, 2021Assignee: SHENZHEN INSTITUTES OF ADVANCED TECHNOLOGYInventors: Junyu Zhang, Hui Huang

Patent number: 10456873Abstract: Welding wire for gas protective welding of reduced activation ferritic/martensitic steel and the manufacturing method, chemical components (weight percentage, wt %): C: 0.10˜0.15, Cr: 8.0˜9.0, W: 1.0˜1.6, V: 0.15˜0.25, Ta: 0.10˜0.17, Mn: 0.50˜0.70, Si: 0˜0.05, N: 0˜0.02, O, Ni, Cu, Al, and Co: 0˜0.01 respectively, P, S, Ag, Mo, and Nb: 0˜0.005 respectively, and balance of Fe. The welding wire has Cr equivalent weight of less than 11, Ni equivalent weight of greater than 3.5. It is manufactured with a wire rod through multi-pass drawing. The rod is subject to annealing heat treatment, tempering treatment performed between the passes of drawing. The annealing process is: the rod is at 940˜1020° C. for 20˜60 minutes, and the n cooled to below 650° C. at rate of less than 45° C./hour, air-cooled to room temperature. The tempering process is: the rod is at 760˜820° C. for 0.5˜2 hours. It reduces forming of ? ferrites in welded joints.Type: GrantFiled: December 15, 2015Date of Patent: October 29, 2019Assignee: Hefei Institutes of Physical Science, Chinese Academy of SciencesInventors: Bo Huang, Qunying Huang, Junyu Zhang, Yutao Zhai, Chunjing Li, Shaojun Liu, Yican Wu
