  • Patent number: 11817184
    Abstract: A computational method simulating the motion of elements within a multi-element system using a graph neural network (GNN). The method includes converting a molecular dynamics snapshot of the elements into a directed graph comprised of nodes and edges. The method further includes the step of initially embedding the nodes and the edges to obtain initially embedded nodes and edges. The method also includes updating the initially embedded nodes and edges by passing a first message from a first edge to a first node using a first message function and passing a second message from the first node to the first edge using a second message function to obtain updated embedded nodes and edges, and predicting a force vector for one or more elements based on the updated embedded edges and a unit vector pointing from the first node to a second node or the second node to the first node.

  • Patent number: 11747676
    Abstract: Disclosed is a display device. The display device achieves a slim bezel by forming a through hole at a bottom portion of a cover, and changing a connection structure of a sub-FPCB to be connected to a main FPCB such that the connection structure extends through the cover without extending along the outside of the cover. The display device achieves a reduction in the thickness of the display device and an enhancement in picture quality through change of an installation direction of an LED module constituted by a main FPCB and LED elements disposed at one surface of the main FPCB. The display device can reduce a space where a sensor unit is disposed in conventional cases by mounting the sensor unit on the LED module, and can realize an additional function such as skin care or sterilization in accordance with the kind of the sensor unit.
