Patent number: 11706508Abstract: The embodiments of the present application relates to a camera, comprising a first housing, a stitching lens mechanism, and a driving assembly. The stitching lens mechanism is mounted in the first housing, and the stitching lens mechanism comprises at least two first assemblies, the first lens assembly comprises a first lens, a first included angle is formed between at least two first lenses. A driving assembly is connected to the first lens assembly through a rotating assembly. At least two first lenses are distributed in a first plane, the first housing is rotatably arranged in a second plane, and the second plane is perpendicular to the first plane. Each of the first lens assemblies takes pictures in different orientations for the same scene, so that the imaging field of view is larger. So that the first housing can rotate under the drive of the driving assembly, that is, the stitching lens mechanism can rotate.Type: GrantFiled: January 15, 2020Date of Patent: July 18, 2023Assignee: Hangzhou Hikvision Digital Technology Co., Ltd.Inventors: Peng Xu, Zhan Ye, Caisheng Yan, Hongjie Guan, Yang Li, Yufei Ma

Patent number: 9982142Abstract: This invention relates to a zinc-rich epoxy anti-corrosion coating comprising a component A capable of being cured into a film, and a component B containing a curing agent, wherein the component A comprises, by mass percentage, 0.1-5 wt % graphene, 0-35 wt % zinc powder, 30-70 wt % filler, 10-20 wt % epoxy resin having 54 wt % solid content, and 10-20 wt % solvent, wherein the sum of the mass percentage contents of the graphene, zinc powder and filler is 60-80 wt % and the sum of the mass percentage contents of all components of component A is 100 wt %. According to the present invention, the addition of graphene to an anti-corrosion coating decreases the thickness of the coating film, reduces the amount of zinc powder while increases the anti-corrosion effect. It reduces zinc oxide vapour generated during welding and is environmentally friendly.Type: GrantFiled: May 5, 2014Date of Patent: May 29, 2018Assignee: THE SIXTH ELEMENT (CHANGZHOU) METERIALS TECHNOLOGY CO., LTD.Inventors: Qiongxin Liu, Xiaolan Qu, Hongtao Xu, Yan Qu, Yufei Ma, Huailiang Xu, Zhenyu Tian

Patent number: 9779303Abstract: A system and process for video characterization that facilitates video classification and retrieval, as well as motion detection, applications. This involves characterizing a video sequence with a gray scale image having pixel levels that reflect the intensity of motion associated with a corresponding region in the sequence of video frames. The intensity of motion is defined using any of three characterizing processes. Namely, a perceived motion energy spectrum (PMES) characterizing process that represents object-based motion intensity over the sequence of frames, a spatio-temporal entropy (STE) characterizing process that represents the intensity of motion based on color variation at each pixel location, a motion vector angle entropy (MVAE) characterizing process which represents the intensity of motion based on the variation of motion vector angles.Type: GrantFiled: September 2, 2004Date of Patent: October 3, 2017Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Hong-Jiang Zhang, Yufei Ma
