Abstract: A construction process support system that enables diverse users to quickly and intuitively create construction model data according to their intentions using natural language input and grid-based positioning. The system comprises hardware processors, software modules, and databases configured to display user interface pages to terminals and control natural language input messages. When input messages contain grid labels that specify coordinates on pages with character codes regarding construction structures, the system requests a Large Language Model (LLM) to generate instruction codes describing construction model data including the grid labels as position information. The LLM generates the requested instruction codes. The system stores the construction model data as searchable data in the database, forwards input messages to chat areas, and renders each structure as three-dimensional data at grid label positions on page canvases.

Abstract: A slip ring device comprises a cylindrical body of an insulating material, at least one ring of an electrically conductive material fitted on the outer periphery of the cylindrical body, at least one strip member of an electrically conductive material arranged on the outer periphery of the ring, a coupling member, situated between the strip member and the outer periphery of the ring, for electrically coupling the strip member and the outer periphery of the ring, at least one lead member of an electrically conductive material, having one end portion electrically connected to the ring and the other end portion led out of the inner periphery of the cylindrical body, and a brush unit of an electrically conductive material, situated in electrical contact with the strip member.
