Patent number: 12236703Abstract: A method and system for fish identification based on body surface texture features and geometric features are provided. The method employs an improved Resnet network and a deep learning Yolov8 network to extract body surface texture features and geometric features of a fish on the basis of considering influences of fish tail swing and an oxygen concentration on a fish body form based on a small sample learning framework, and then realizes identity recognition of a fish individual by coupled analysis of the body surface texture features and the geometric features. The method can realize high-accuracy fish identification with few training samples of a fish to be identified from the perspective of actual application, provides theoretical basis and technical support for accurate fish stock assessment and accurate estimation of industrially farmed fish biomass, and meets the development requirements of modern agriculture.Type: GrantFiled: October 29, 2024Date of Patent: February 25, 2025Assignee: Zhejiang UniversityInventors: Jian Zhao, Feixiang Zhu, Haijun Li, Xiaofeng Qi, Ruiji Mahe, Zhangying Ye, Songming Zhu, Ying Liu

Publication number: 20240083307Abstract: Disclosed in the utility model is a vertical latch locking mechanism for a rotating seat, including a vertical latch locking mechanism mounted on a rotating disc in a seat rotation mechanism, at least one lockhole provided on a disc surface of a fixed disc in the seat rotation mechanism, and at least one first lock pin hole provided on the rotating disc. The lockhole is aligned with the first lock pin hole, and the vertical latch locking mechanism includes: a locking pin bracket fixed on the rotating disc; and at least two lock pins vertically and moveably configured on the locking pin bracket. A first end of the lock pin passes through the first lock pin hole and is inserted into the lockhole, to implement locking. In the utility model, a horizontal locking mechanism is changed to a vertical latch mechanism, radial sizes of the rotating disc and the fixed disc are greatly reduced, and a diameter can be reduced to less than 200 mm.Type: ApplicationFiled: November 16, 2023Publication date: March 14, 2024Applicant: Yanfeng International Seating Systems Co., Ltd.Inventors: Qingwei Feng, Jiabin Ding, Feixiang Zhu

Patent number: 11858382Abstract: The present invention discloses a seat rotation locking mechanism, including a locking mechanism mounted on a rotating disc in a seat rotation mechanism and at least one lockhole disposed on an outer circumference of a fixed disc in the seat rotation mechanism, where the locking mechanism includes: a lock support fixed on the rotating disc; and at least two lock pins horizontally and moveably configured in the lock support, where a first end of the lock pin is of a truncated-cone-shaped structure; and the first end of the lock pin is inserted into the lockhole, to implement zero-clearance locking by using wedging between the truncated-cone-shaped structure of the first end of the lock pin and the lockhole. The present invention eliminates a fit clearance existing after a rotation mechanism is locked, improves a grade of a product, and improves user experience.Type: GrantFiled: May 9, 2019Date of Patent: January 2, 2024Assignee: YANFENG INTERNATIONAL SEATING SYSTEMS CO. LTD.Inventors: Qingwei Feng, Jiabin Ding, Feixiang Zhu

Patent number: 10857914Abstract: A locking device includes a locking pin mounting box, a locking pin, a locking spring, a handle and an unlocking tension spring. Respective ends of the locking pin pass through corresponding locking pin guide holes in lateral sides of the locking pin mounting box. A spring bearing boss is provided in a middle position of each locking pin. The locking spring surrounds the corresponding locking pin with one locking spring end in contact with one lateral side and another end in contact with the spring bearing boss. One end of the handle is hinged to a top side of the locking pin mounting box. The unlocking tension spring has one end connected to the handle and another end connected to an end of the locking pin that has passed through the first lateral side. In the locking device, the locking pin is inserted into a locking hole to achieve locking.Type: GrantFiled: November 27, 2018Date of Patent: December 8, 2020Assignee: Adient Engineering and IP GmbHInventors: Qingwei Q.
