  • Patent number: 11436758
    Abstract: A method according to an embodiment of the present invention includes acquiring an image of a urine test kit equipped with a biochemical sample rod including a plurality of pad cells including a plurality of sub-pad cells, extracting at least one potential RGB value from the image by means of a potential color extractor, and converting and analyzing the at least one potential RGB value using a plurality of color spaces included in a color space conversion engine and a color space analysis engine by means of an analyzing unit. The plurality of color spaces are randomly generated, and a color space having a smallest distance value from the potential RGB value is determined as an optimal color space.

  • Patent number: 10605364
    Abstract: A vehicle parking apparatus may include a parking rod having a first end portion connected to a detent plate and a second end portion on which a cam is placed, the parking rod rectilinearly moving in accordance with rotation of the detent plate and causing the cam to rotate a sprag about a rotation shaft; and a ā€˜U’-shaped stopper extending from the second end portion of the parking rod and operating to surround or release the sprag in accordance with the motion of the parking rod, the stopper allowing rotation of the sprag by releasing the sprag when the detent plate is rotated to a P range position and preventing the rotation of the sprag by surrounding the sprag when the detent plate is rotated to a certain range position other than the P range position.

  • Patent number: 6770696
    Abstract: Disclosed is a method for preparing a clay-dispersed polymer nanocomposite. In this method, a polymer, which carries oxygen atoms within the repeating units of its backbone and is thermodynamically compatible with a binder resin, is used as a matrix resin. Useful is poly(&egr;-caprolactone) owing to its thermodynamic compatibility with poly(styrene-co-acrylonitrile)copolymers, poly(acrylonitrile-co-butadiene-co-styrene) copolymers, and poly(vinylchloride) resins. Poly(&egr;-caprolactone) resins aid the binder resins to penetrate into silicate layers so that the silicate of the organophilic clay was completely delaminated to silicate lamellas.
