  • Patent number: 10918479
    Abstract: A stent (1) used for a heart valve prosthesis and the heart valve prosthesis that includes the stent (1) and is used for heart valve replacement. The stent is configured to support a heart valve (3) and includes, along a longitudinal axis, an inflow section (8), an outflow section (6) and a transition section (7) between the inflow section (8) and the outflow section (6). The stent (1) has a contracted delivery configuration and an expanded deployed configuration. In the expanded deployed configuration, the inflow section (8) defines a concave contour that is complementary to a structure of a native valve annulus. The concave contour enables self-deployment and close adherence of the stent (1), thereby preventing its displacement and perivalvular leakage after implantation.

  • Publication number: 20210043098
    Abstract: Methods and systems of active discovery and collaborative collision avoidance are described for aircrafts. Specifically, an aircraft predicts firstly the four-dimensional information of its short future flight path based on existing information, then shares the information actively among its adjacent aircrafts, realizes finally collaborative collision avoidance based on the future flight paths of adjacent aircrafts. The described methods contain the following steps: prediction and broadcast of short future flight path, broadcast reception and analysis and collision avoidance, and resumption of planned path and state. According to the methods, a system is also described to implement the above method and it contains seven corresponding modules. Since sharing the future information rather than the past information among aircrafts, the advantage of this intervention is strong real-time, low computation complexity, low cost, and more aircrafts accommodated in the same space.
