Abstract: A method for registering a wireless device by a terminal in a wireless communication system is provided. The method includes obtaining connection information for the wireless device by scanning a recognition code of the wireless device in a first mode, transitioning to a second mode based on the connection information and receiving a connection request from the wireless device, performing a connection operation to the wireless device to transmit network access information to the wireless device, and transitioning to the first mode, and registering the wireless device upon detecting connection of the wireless device to a network in the first mode.

Abstract: An apparatus and method for manufacturing a grilled seaweed includes the apparatus comprising a grilling unit having a first housing with a first inlet opening and a first outlet opening which communicate with each other; a first conveyor for transferring a sheet of seaweed from the first inlet opening to the first outlet opening; a first heating source installed over the first conveyor to discharge a flame onto a top surface of the seaweed being transferred by the first conveyor; and a second heating source installed on both sides of a lower portion of the first conveyor to apply a flame onto a bottom surface of the seaweed being transferred by the first conveyor.

Abstract: A serial port switching circuit includes an input/output controller contained in a computer system, the input/output controller including first and second serial ports for performing serial data communication with external equipment, first and second connectors connected to the external equipment, and a switching arrangement connected between the first and second serial ports of the input/output controller and the first and second connectors, for selectively connecting the first and second serial ports to the first and second connectors in response to a control signal being applied according to a user's selection to allow the input/output controller to perform the serial data communication with the external equipment. According to the present invention, the user can simply switch the connections between the first and second serial ports of the input/output controller and the first and second connectors.
