Publication number: 20240094346Abstract: An optical system includes a housing defining a cylindrical lens array. A first light source is located in the housing and positioned to emit a first wavelength of light into a first field of illumination impinging on the cylindrical lens array. A second light source is located in the housing and positioned to emit a second wavelength of light into a second field of illumination impinging on the cylindrical lens array. The cylindrical lens array alters the first field of illumination and the second field of illumination and increases an overlap between the first field of illumination and the second field of illumination. A detector is located in the housing and positioned to receive a first redirected portion of the first wavelength of light and a second redirected portion of the second wavelength of light.Type: ApplicationFiled: August 18, 2023Publication date: March 21, 2024Inventors: Xi Chen, Xiaoyang Zhang, Prashanth S.

Patent number: 11906616Abstract: The present disclosures discloses a method of target feature extraction based on millimeter-wave radar echo, which mainly solves the problems that techniques in the prior art cannot fully utilize raw radar echo information to obtain more separable features and cannot accurately distinguish targets with similar physical shapes and motion states. The method is implemented as follows: acquiring measured data of targets, generating an original RD map, and removing ground clutter of the map; sequentially performing target detection, clustering and centroid condensation on the RD map after the ground clutter removal; acquiring a continuous multi-frame RD maps and carrying out the target tracking; according to the tracking trajectory, selecting candidate areas and extracting features based on a single piece of RD map and features based on two successive RD maps, respectively.Type: GrantFiled: July 21, 2021Date of Patent: February 20, 2024Assignee: Xidian UniversityInventors: Lan Du, Zengyu Yu, Xiaoyang Chen, Zenghui Li, Chunxin Wang

Publication number: 20230379234Abstract: An Internet of Things device includes an anomaly monitoring switch such that the Internet of Things device performs anomaly monitoring when the anomaly monitoring switch is enabled. An anomaly rule is stored in the Internet of Things device. According to the anomaly rule, the Internet of Things device determines whether a request sent by the Internet of Things device is an anomaly request and whether a control instruction received from an Internet of Things cloud platform is an anomaly control instruction. When the anomaly request or anomaly control instruction is received, the Internet of Things device discards the anomaly request or the anomaly control instruction.Type: ApplicationFiled: September 13, 2021Publication date: November 23, 2023Inventors: Xiaoyang Chen, Zhenfang Ji, Wenyuan Zhao, Hai Zhou, Fen Yang

Patent number: 11308095Abstract: A system may retrieve a pattern from a pattern database with the pattern identifying a type of sensitive data. The system may also retrieve data identified by a variable from a big data management system. The system may then match the data to the pattern to detect the type of sensitive data in the data. An output may be generated in response to the data matching the pattern. A variable access permission may be retrieved for the variable from a permissions repository, a sensitive data permission may be retrieved for the type of sensitive data from the permissions repository, and the variable access permission may be compared to the sensitive data permission to detect a discrepancy.Type: GrantFiled: October 8, 2019Date of Patent: April 19, 2022Assignee: American Express Travel Related Services Company, Inc.Inventors: Ravi Arasan, Sandeep Bose, Xiaoyang Chen, Debasish Das, Matthew Kent Meyer, Gurusamy Ramasamy, Jeremy D.
