Abstract:
Provided is an electric bus and an electric bus battery exchange system. The electric bus according to the present invention includes: a battery exchange hole disposed on top of the electric bus for exchanging a discharged battery for a charged battery; a front camera unit taking front images in the process of entering the battery exchange station for battery exchange; a communication unit for receiving position information of the battery exchange unit from the battery exchange station; a route output unit outputting a predicted driving route for reaching a swapping point below the battery exchange unit based on the front images taken by the front camera unit and the position information of the battery exchange unit; and a display unit displaying the predicted driving route outputted by the route output unit, superimposed on the front images taken by the front camera unit.
Abstract:
Provided is a blade for a wind power generator comprising: a main spar including: an upper main spar flange and a lower main spar flange whose both ends are protruded towards the front and rear side respectively; a front main spar web and a rear main spar web which are connecting the upper main spar flange and the lower main spar flange; a first body, located in the front side of the main spar, including an inverted D-type rib; and a second body, located in the rear side of the main spar, including a curved rib. The inverted D-type rib includes: a vertical frame; and a block frame extendedly formed from the upper side and the lower side of the vertical frame respectively and convexly formed towards the front side.
Abstract:
A system for automatically exchanging a battery of an electric vehicle, the system including a horizontal frame of a predetermined area formed at a location higher than the electric vehicle; a plurality of battery stands formed on a bottom surface of the horizontal frame at a predetermined interval; a pair of fixed guide rails arranged and installed on front and rear sides or left and right sides of the horizontal frame, respectively; a variable guide rail adapted to move horizontally along X-axis or Y-axis along the fixed guide rails; a movable rail adapted to move horizontally along Y-axis or X-axis along the variable guide rail and ascend/descend vertically; and a grasping means installed on a lower end of the movable rail and adapted to pick up a battery of the electric vehicle or a battery seated on the battery stand and exchange each other.
Abstract:
Provided is a blade for a wind power generator including: a main spar; a front rib and a rear rib respectively located in the front side and the rear side of the main spar; and a skin, installed on the main spar, the front rib and the rear rib, constituting the outer skin of the blade. The skin is coupled by a zipper formed in the skin. The zipper includes an end portion zipper connecting the both end portions of the skin. The end portion zipper is covered by a cover portion provided in the skin. The cover portion covers the end portion zipper from the front side of the suction surface of the blade towards the rear side of the suction surface of the blade.
Abstract:
Disclosed are a method and apparatus for processing a hand gesture command for a media-centric wearable electronic device in an Internet of Media Things and Wearables (IoMTW) system. The processing method according to an embodiment includes acquiring a hand image of a user, distinguishing a background area and a hand area in the acquired hand image, detecting a hand shape using the distinguished hand area and generating hand contour information describing the detected hand shape, detecting a hand movement path based on a change of the distinguished hand area over time and generating hand trajectory information describing the detected hand movement path, and recognizing a hand gesture of the user using the hand contour information and the hand trajectory information.
Abstract:
Smart glasses, and a system and method for processing a hand gesture command using the smart glasses. According to an exemplary embodiment, the system includes smart glasses to capture a series of images including a hand gesture of a user and represent and transmit a hand image, included in each of the series of images, as hand representation data that is represented in a predetermined format of metadata; and a gesture recognition apparatus to recognize the hand gesture of a user by using the hand representation data of the series of images received from the smart glasses, and generate and transmit a gesture command corresponding to the recognized hand gesture.
