Abstract: A power supply system for an aircraft and a control method thereof are provided. The power supply system of the aircraft includes a fuel cell configured to generate electrical energy, a converter device configured to supply a voltage generated by the fuel cell to a first motor device for driving the aircraft through a first output terminal and switch a connection with the fuel cell depending on a predetermined driving mode, a battery configured to supply the voltage to a second motor device for driving the aircraft through a second output terminal, the second output terminal being connected with an output node of the fuel cell, and a processor configure to control a connection between the fuel cell and the converter device depending on the driving mode.

Abstract: A semiconductor device includes a line; a source structure on the line; a stack structure on the source structure; a first slit structure penetrating the stack structure; a second slit structure penetrating the stack structure; and a contact plug adjacent to the first slit structure in a first direction. The first slit structure and the second slit structure may be spaced apart from each other by a first distance in a second direction that is perpendicular to the first direction. The contact plug penetrates the source structure, the contact plug being electrically connected to the lower line. The first slit structure and the contact plug may be spaced apart from each other by a second distance in the first direction, and the second distance may be longer than the first distance.

Abstract: A display device includes a base substrate, a pixel defining layer disposed on the base substrate and including a first opening, a light emitting structure disposed in the first opening of the pixel defining layer, a thin film encapsulation layer disposed on the light emitting structure, a touch electrode disposed on the thin film encapsulation layer, an insulating pattern disposed on the touch electrode and including a second opening which overlaps the first opening, and a high refractive layer disposed on the insulating pattern, the high refractive layer including a plurality of grid patterns disposed on a top surface of the high refractive layer, and a refractive index higher than a refractive index of the insulating pattern.

Abstract: A shark fin antenna equipped with a V2X communication system which ensures high-efficiency performance in a moving vehicle, thereby wirelessly providing various frequency transmitting/receiving signals to a user's vehicle, an adjacent vehicle as desired by the user, and a pedestrian, whereby an integrated telematics service including a safety based service is provided. The shark fin antenna includes a fixing part arranged on which an antenna is installed within an applicable range of its internal space, produces an antenna similar to the form of the fixing part, thereby implementing a small-sized antenna and smoothly receiving signals of various bands due to favorable antenna gain and radiation pattern condition, and combines the antenna gain and radiation pattern condition while providing the forms of an antenna unit and an auxiliary unit, thereby flexibly responding to receiving signals of different bands according to use regions.
