Provided is an automotive around view image providing method using a machine learning model. The method includes: receiving, by an image processing device, a plurality of images obtained by a plurality of cameras mounted on a car; inputting, by the image processing device, the plurality of images to a neural network encoder to generate a feature vector for each of the plurality of images; and combining, by the image processing device, feature vectors for the plurality of images into one image form and inputting the one image form to the neural network decoder to generate a matched one image. The neural network decoder includes a filter for performing matching on adjacent images having an overlapping area among the plurality of images based on the feature vector for the plurality of images.

A high-strength one-touch rebar coupler includes a coupler body having a hollow portion in the longitudinal direction. The coupler body is formed in a helical shape to provide the inner peripheral surface of the hollow portion with a rebar fastening force in the circumferential direction. The coupler body includes a first guide helix coupling portion, which has first guide sloping portions that slope from the center portion of the hollow portion towards the outside of one side thereof, and a second guide helix coupling portion, which has second guide sloping portions that slope from the center portion of the hollow portion towards the outside of the other side thereof. A first fastening unit is screw-coupled to the first guide helix coupling portion and inserted into one side of the hollow portion. The first fastening unit includes first fastening members, which are slidably coupled to the first guide sloping portions.

The present invention relates to a nano-composite containing anionic and cationic polymers and a method for preparing thereof, and more particularly to a poly-gamma-glutamic acid (γ-PGA)/chitosan/manganese iron oxide nanoparticle composite prepared by encapsulating iron oxide-based nanoparticles in a γ-PGA/chitosan polymer composite using the ionic self-assembly properties of poly-gamma-glutamic acid (γ-PGA) and chitosan, which are biocompatible polymer materials, and to a method for preparing thereof.The present invention provides a magnetic resonance imaging nano-contrast agent based on a nanoparticle composite including iron oxide-based nanoparticles encapsulated in a self-assembled composite of anionic poly-gamma-glutamic acid (γPGA) and cationic chitosan. The iron oxide-based nanoparticles encapsulated in the composite interact with each other to produce a synergistic effect on the amplification of magnetic resonance signals, and thus have an relatively excellent contrast effect compared to when they exist as single particles.

A display substrate includes a base substrate, a micro shutter, a first driving electrode, a second driving electrode, and a plurality of anchors. The micro shutter includes a flat portion having at least one opening, a main concave portion adjacent to the opening and extending in from the flat portion to a first depth, and at least one sub-concave portion extending in from a bottom surface of the main concave portion to second depth. The first driving electrode is connected to a first side of the micro shutter. The second driving electrode is connected to a second side of the micro shutter. The second side is positioned opposite to the first side. The anchors fix the first and second driving electrodes on the base substrate.
摘要:
The display apparatus including a microelectromechanical (MEMS) shutter is disclosed. The MEMS shutter is shifted by the switching element in a horizontal direction corresponding to the light control area to turn on or turn off the light control area. A first slit transmits light generated from the light source to the MEMS shutter of a first substrate and a second slit of a second substrate corresponding to the first slit provides apertures by overlapping the first slit and the second slit. The apertures of the MEMS shutter are distributed on a two dimensional plane and form a geometrically symmetric pattern that are capable of enhancing light-use efficiency.
