Abstract: A wind power generation system and a moving body are disclosed. The wind power generation system comprises: a rail part for providing a horizontal movement path; and a plurality of moving bodies for moving along the movement path of the rail part. The moving body may comprise: a blade for providing power for the movement of the moving body on the basis of energy generated by the wind; a plurality of wheels, which engage with the rail part and rotate on the basis of the power provided by means of the blade, so as to move the moving body along the movement path of the rail part; and a nacelle having a power generator for producing electricity on the basis of the rotational force of the wheels.

Abstract: A 3D printing-based face mask is disclosed. The face mask may comprise: a mask body which corresponds to the shape of the lower portion of a user's face and displays the shape of the user's lower portion on the outer surface thereof; at least one filter part which is mounted on at least one side of the mask body; and ear hanging parts for fixing the mask body on the user's ears. The mask body can be generated by 3D printing based on a 3D mask model corresponding to the shape of the lower portion of the face, including the lower part of the user's nose and mouth, and the at least one filter unit is mounted in correspondence with at least one of the lower part of the nose and the mouth. Accordingly, the user can wear the mask without aesthetic texture.

Abstract: Disclosed are an eye-tracking-based image transmission method, device and system. The eye-tracking-based image transmission method enables: receiving multiple images acquired from multiple cameras; generating a synthesized image on the basis of the multiple images; displaying the synthesized image on a screen; detecting the gaze of a user in real-time; selecting, from the synthesized image, the image corresponding to an area at which the user is gazing; and transmitting the selected image. Thus, an image that dynamically changes according to the gaze of a user may be provided via broadcasting.

Abstract: Disclosed are a multiple camera-based image transmission method, device and system. The image transmission method enables: acquiring multiple images by using multiple cameras; displaying a screen displayed on a monitor so as to be segmented into multiple areas corresponding to the multiple images; detecting an area at which a user is gazing; selecting the image that corresponds to the detected area; and transmitting the selected image via broadcasting. Thus, on the basis of multiple images, a broadcast image may be switched according to the gaze of a user.
