    摘要: A user-guidance system that utilizes augmented-reality (AR) components and human-posture-detection techniques is presented. The user-guidance system can help users to use smart devices to conduct 3D body scans more efficiently and accurately. AR components are computer generated for the on-screen guidance to guide a camera operator to position the camera in a particular location in relation to a target object with a particular tilt orientation in relation to the target object to capture an image that includes a region of the target object for 3D reconstruction of the target object. Human-posture-detection techniques are used to detect a human user's real-time posture and provide real-time on-screen guidance feedback and instructions to the human user to adopt an intended best posture for 3D reconstruction of the human user.

    摘要: The shock tube comprises a tube, a first electrode, a second electrode and a stopple, wherein the tube is internally provided with a cavity for accommodating a target liquid sample. The first electrode is arranged at one end of the tube. The second electrode is arranged in the stopple, and the outer end of the second electrode can be electrically connected with the exterior via an opening of the stopple. The stopple is internally provided with an elastic piece connected with the second electrode. The outer side of the elastic piece is connected with the stopple, and the inner side of the elastic piece is connected with the second electrode. The invention further provides a cell electroporation device where the shock tube can be placed.
