Abstract: An interactive activity generating method, which includes setting a database for storing addresses of interactive activity platforms, providing creating options of interactive activities in an activity creating interface. The method includes setting an information configuration interface corresponding to a creating option of each interactive activity for filling in interactive activity information. The method includes detecting a selected creating option in the activity creating interface when an interactive activity is created, and finding an address of a corresponding interactive activity platform in the database. The method includes sending interactive activity information filled in an information configuration interface corresponding to the selected creating option to the interactive activity platform. The method includes generating an interactive activity interface after compiling by the interactive activity platform.

Abstract: A system includes a tool configured to be positioned proximate to respective welding surface of separate components. The tool includes a tool head and an actuator configured to drive rotation of the tool head. The tool also includes a controller having a memory operatively coupled to a processor. The processor is configured to provide a command signal to the actuator to apply a pulsed torque to drive rotation of the tool head to facilitate joining the respective welding surfaces of the separate components to one another.

Abstract: Plastic zone extrusion may be provided. First, a compressor may generate frictional heat in stock to place the stock in a plastic zone of the stock. Then, a conveyer may receive the stock in its plastic zone from the compressor and transport the stock in its plastic zone from the compressor. Next, a die may receive the stock in its plastic zone from the conveyer and extrude the stock to form a wire.
