Abstract: A method and an apparatus for detecting a lane is provided. The lane detection apparatus according to an embodiment includes: an acquisition unit configured to acquire a front image of a vehicle; and a processor configured to input the image acquired through the acquisition unit to an AI model, and to detect information of a lane on a road, and the AI model is trained to detect lane information that is expressed in a plane form from an input image. Accordingly, data imbalance between a lane area and a non-lane area can be solved by using the AI model which learns/predicts lane information that is expressed in a plane form, not in a segment form such as a straight line or curved line.

Abstract: This application relates to a self-reference point setting type blood component measuring method and apparatus using light. In one aspect, the method includes applying light to a skin of a subject to be measured and setting a reference point on a surface of the skin adjacent to a point at which the light is applied. The method further includes calculating a concentration of a blood component from a light intensity measured at the reference point and a light intensity measured at another point. According to some embodiments, the accuracy and precision of measurement are increased in measuring blood in a non-invasive manner.

Abstract: This application relates to a method for manufacturing a hybrid moisture barrier layer. In one aspect, the method includes preparing a base film and applying a photo-curable or heat-curable solution material to the base film, followed by photocuring or thermal curing to deposit at least one first moisture barrier layer. The method also includes depositing at least one second moisture barrier layer on the base film through atomic layer deposition (ALD), the second moisture layer being ⅓ to ½ the total thickness of the first moisture barrier. According to various embodiments, a combination of a moisture barrier layer formed by applying the photo-curable or heat-curable solution and a moisture barrier layer formed by atomic layer deposition at an effective thickness ratio brings about an effective reduction in production lead time as well as an improvement in the reliability of moisture barrier effect.
