Abstract: A method and apparatus for inspecting an aeronautical light using an aerial vehicle are disclosed. The method includes defining a first reference point based on a plurality of aeronautical lights installed on a runway surface, and defining a second reference point based on the first reference point, defining a flight path of the aerial vehicle taking off from the second reference point and heading to the first reference point, transmitting, to the ground, an image of the aeronautical lights photographed by the aerial vehicle, and inspecting and adjusting elevation angles of the aeronautical lights by analyzing the image of the aeronautical lights in real time.

Abstract: A vacuum cleaner is disclosed, including suction means for providing suction force, a suction nozzle for drawing room air by the suction force provided from the suction means, a dust collecting box for receiving the room air drawn through the suction nozzle, an upper cover having an opening at a central portion thereof for selective opening/closing of an upper portion of the dust collecting box, and a filter assembly selectively fastened to an edge of the opening, for filtering dust from the drawn air, and discharging the air to upward, thereby making cleaning and replacement of the dust collector assembly easy.

Abstract: Disclosed is a vacuum cleaner including a sucking nozzle for sucking air; a dust collecting assembly including a dust collecting container with an opened top surface, a top lid for opening and closing a top of the dust collecting container, an inlet for sucking air to the inside of the dust collecting container, a filtering device coupled with the top lid, and an outlet provided at a bottom of the dust collecting assembly for discharging clean air to a lower part of the dust collecting container; and a cleaner body including a dust collecting assembly receiving recess for detachably receiving the dust collecting assembly, a polluted air outlet provided at the dust collecting assembly receiving recess and coupled with the dust collecting assembly inlet for discharging polluted air sucked in through the sucking nozzle, and a clean air inlet provided on a floor of the dust collecting assembly receiving recess and communicating with the outlet of the dust collecting assembly, and a clean air conduit for dischargi
