  • Patent number: 10810371
    Abstract: An artificial intelligence problem is solved using an artificial intelligence memory graph data structure and a lexical database to identify supporting knowledge. A natural language input is received and classified into components. A starting node of an artificial intelligence memory graph data structure, which comprises one or more data nodes, is selected to begin a search for one or more supporting knowledge data nodes associated with the classified components. Starting at the starting node, the artificial intelligence memory graph data structure is searched using a lexical database to identify the one or more supporting knowledge data nodes. An artificial intelligence problem is identified and solved using the one or more identified supporting knowledge data nodes of the artificial intelligence memory graph data structure.

  • Patent number: 10654130
    Abstract: A polarization module and a laser exposure apparatus have a polarization module including a first lens and a second lens that reduce a one-directional length of a cross-section of an incident laser beam having an optical axis. A polarization beam splitter divides the laser beam passing through the first and second lenses into two laser beams that are polarized in different directions with respect to each other. A first prism lens and a second prism lens emit an output laser beam by controlling the two laser beams that are divided by the polarization beam splitter to positions that are symmetrical with respect to the optical axis. At least one half wave plate is disposed between the polarization beam splitter and the first prism lens.
