A method and device for transforming 2D images into 3D are disclosed. The disclosed device includes a dictionary storage unit configured to store a word-depth gradient dictionary; a color patch obtainer unit configured to obtain color patches from an input image; a matching word search unit configured to transform each of the color patches obtained by the color patch obtainer unit into a SIFT descriptor form and search for words closest to the SIFT descriptors of the obtained color patches from among the words of the word-depth gradient dictionary; a matching depth gradient obtainer unit configured to obtain depth gradient information of the words matching the obtained color patches from the word-depth gradient dictionary; and a depth map generation unit configured to compute a depth from the obtained matching depth gradient for each of the obtained color patches and generate a depth map.

Disclosed herein is a fibrous separation membrane for secondary batteries, comprising: a polymer layer which partially melts and blocks pores thereof thus cutting off electric current when a temperature of a secondary battery is increased; and heat-resistant resin layers applied on both sides of the polymer layer.

Fibrous separation membrane for secondary battery and manufacturing method thereof

The present invention relates to a porous sheet and a method for manufacturing the porous sheet. A porous sheet including a fine-fiber web layer and a support layer and a method for manufacturing the same are provided, and it is possible to implement a porous sheet with sufficient strength and thickness to be used in peeling and laminating processes of a multilayer ceramic capacitor.

Porous sheet and method for manufacturing the porous sheet

A lens injection mold includes an upper mold and a lower mold, a cavity provided in the upper mold or the lower mold and having a shape corresponding to the rib portion having the concave portions in order to form the rib portion, and an upper core and a lower core disposed to be movable inside the upper mold and the lower mold and having an upper tip portion and a lower tip portion, respectively, the tip portions having a shape corresponding to the effective aperture portion such that the effective aperture portion is created by pressing injection liquid.

Lens injection mold

A liquid lens for adjusting a focal length by electro-wetting. A body houses a non-conductive fluid and a conductive fluid therein. A cover is capped on the body. A first adhesive bonds the body to the cover, the first adhesive curing rapidly. Also, a second adhesive bonds an outer periphery of the body to an outer periphery of the cover. The glass cover and the body are bonded across a large area by two types of adhesives with different compositions. This allows the lens manufactured to greatly withstand temperature and heat impact and stay durable in a high-temperature humid environment, thereby significantly elevating a quality of the final product.

Liquid lens having improved sealing structure

A method of fabricating a liquid lens which can prevent unstable movement of liquids while sealing a hole containing the liquids by applying voltage to a chamber containing the liquids to induce electrowetting, and a liquid lens fabricated thereby. The method includes providing a chamber with a hole formed therein for containing liquid and injecting two non-miscible liquids with different refractive indices. The method also includes placing a conductive transparent plate to be in contact with the liquid on the top and applying voltage to the conductive transparent plate and the chamber to induce electrowetting, thereby changing the shape of meniscus between the two liquids. The method further includes covering an upper surface of the chamber with the conductive transparent plate to seal the hole.
