Abstract: A propulsion module of an air mobility vehicle may include a door provided in the housing and opening or closing the opening portion of the housing by a sliding motion of the door; a propeller for providing propulsion to the air mobility vehicle; a link assembly having a first end portion connected to the housing and a second end portion connected to the propeller to pull the propeller into the internal space of the housing through the opening portion or pull the propeller outside the internal space through the opening portion; and a door opening and closing portion coupled to the door and configured for providing an opening and closing force to the door according to an inward-pulling motion or an outward-pulling motion of the propeller.

Abstract: A depth-wise convolution acceleration device using an MAC array processor structure according to the present invention may include a data output unit, which receives a data of each row of the image from the data buffer and inputs the data into convolution operation blocks while shifting the data N?1 times according to the kernel size (N×N) and a weight output unit, which receives the kernel data from the kernel buffer and sequentially inputs a weight value constituting the kernel data to each of the row convolution operation blocks, and inputs the weight delaying by N clocks if the row increases as N rows.

Abstract: A seat for a vehicle having a fold-and-dive function is proposed. When a seatback is rotated forwards and folded, a seat cushion is moved down, so the fold-and-dive function of the seat is realized. When a full-flat mode is realized by the reclining operation of the seatback, a rear end of the seat cushion is moved up, so a step between the seat cushion and the seatback can be significantly reduced or eliminated. Furthermore, a front link connecting a back cushion interlocking frame and a cushion fixing bracket to perform the fold-and-dive function is installed to have directivity where it is inclined rearwards, thus preventing a submarine phenomenon of the seat in the event of a forward collision.

Abstract: The present disclosure relates to a vehicle seat wherein matchability with a luggage box is maintained when the seat is folded, and a relax mode and a backward relax mode can be implemented. The vehicle seat according to the present disclosure includes: a tilting link configured to tilt a front portion of a seat cushion upwards/downwards; and a sliding bracket having one end to which a seat is connected by a hinge structure such that the seat is tilted around the hinge structure, the other end of the sliding bracket being connected so as to slide forwards/backwards.

Abstract: An embodiment vehicle door opening/closing system includes an inner panel defining a door open portion of a vehicle, the inner panel including an installation groove having a protruding or recessed shape, a driving device disposed in the installation groove of the inner panel, and a link mechanism installed on a chassis through a rotating shaft, a first end of the link mechanism being connected to the driving device such that power is transferred thereto, and a second end of the link mechanism being connected to a door such that, during driving of the driving device, the link mechanism rotates with reference to the rotating shaft to open/close the door.

Abstract: A non-exhaust fine dust collecting apparatus using friction electricity is disclosed. An exemplary embodiment of the present invention provides a non-exhaust fine dust collecting apparatus using friction electricity, including: an air pipe mounted in a vehicle and provided with an inlet through which fine dust generated in a vehicle and charged with a first polarity flows together with air; and a dust collector mounted at a side of an outlet of the air pipe and charged with a second polarity that is opposite to the first polarity to collect the fine dust charged with the first polarity.
