Patent number: 11900618Abstract: A system and a method for detecting a moving target based on multi-frame point clouds. The system comprises a voxel feature extraction module; a transformer module used for matching and fusing the feature tensor sequence, fusing a first feature tensor with a second feature tensor, fusing the fused result with a third feature tensor, fusing the fused result with a fourth feature tensor, and repeating the fusing steps with a next feature tensor to obtain a final fused feature tensor; and an identification module used for extracting features from the final fused feature tensor and outputting detection information of a target. The method comprises the following steps: S1, constructing each system module; S2, training the model by the data in a training set; S3, predicting by the trained model.Type: GrantFiled: June 20, 2023Date of Patent: February 13, 2024Assignee: ZHEJIANG LABInventors: Yechi Ma, Wei Hua, Quan Feng, Shun Zhang

Patent number: 9959719Abstract: An entry sensor, which supports either wireless or wired operation, facilitates installation and is adjustable for gaps between a building entry barrier such as a door or window and the surrounding frame. The sensor, which may be implemented as a single piece design, includes an adjustment mechanism that enables an installer to vary the extension of the sensor to match the actual gap so that the sensor properly secures the building entry when closed. The sensor includes a detector that determines the state of a switch that is responsive to the movement of a plunger mechanism, where the state is indicative whether the building entry barrier is opened or closed, and that may determine whether the sensor is tampered with. The sensor also may facilitate battery replacement that protects the associated circuitry during the replacement.Type: GrantFiled: September 7, 2017Date of Patent: May 1, 2018Assignee: Salus North America, Inc.Inventors: Samuel Hong-Yen Pai, Wai-Leung Ha, Shen Owyang, Dick Kwai Chan, Wai Yin Shum, Kwok Wa Kenny Kam, Guang Quan Feng

Patent number: 8882827Abstract: The stent comprises a tubular body comprising a plurality of ring units arranged in the axis direction and bridged by a connecting element. Each of the units comprises a plurality of cells connected with each other, each of the cells having a U-shaped form comprising two linear parts and a circular arc part therebetween, and opening toward one end. The ring units comprise first and second units alternatively arranged and the oppositely disposed cells of the first and second units are only partly bridged by the connecting elements. The shapes of the cells of the first and second units are axisymmetrical about the connecting element. The curvature radius of the top of the arc constituting the arc part is 1.1 and 1.5 times larger than that of each of the tangent circles formed at the edges of two linear parts of the cell on the circular arc part side.Type: GrantFiled: September 16, 2010Date of Patent: November 11, 2014Assignee: Japan Stent Technology Co., Ltd.Inventors: Hai Quan Feng, Suguru Kishimoto, Jun Kubota, Minoru Asahara
