Abstract: A battery module includes a sub module including a cell stack having a plurality of battery cells and a pair of bus bar frames respectively coupled to one side and the other side of the cell stack; a module housing configured to accommodate the sub module and configured to have an air inlet and an air outlet formed to circulate air; a sprinkler provided through the module housing at one side of the cell stack in a stacking direction; and an outlet closing device configured to move by a buoyancy generated by a cooling water introduced into the module housing through the sprinkler so that the air outlet is closed.

Abstract: An aberration correction method and apparatus. The apparatus includes at least one processor, and an input/output unit configured to receive an captured image, wherein the processor is configured to initialize a first matrix or a second matrix by reducing a matrix of a point spread function (PSF) of a lens included in a capturing device used to capture the captured image, iteratively perform an aberration removal and a noise removal based on the captured image and the first matrix or the second matrix, and output a final original image as a result of the iteratively performing. Here, the first matrix is a matrix obtained by reducing the number of indices indicating light arrival points of the matrix of the PSF, and the second matrix is a matrix obtained by reducing the number of indices corresponding to light arrival points of a transposed matrix of the PSF.

Abstract: Provided is a method for forming barrier ribs of a plasma display panel (PDP), in which the rear substrate is protected from camber and damage occurring in the pressing process, and the mold can be separated easily by manufacturing a soft mold using elastic silicon rubber and forming uniform barrier ribs in a press method using the soft mold. In addition, a method for manufacturing a transparent soft mold is suggested, and uniform barrier ribs are formed by pressing a photosensitive barrier rib paste with the transparent soft mold, exposing them to a particular light source to reduce contact surface between the mold and the paste and thus make the mold separated easily.

Abstract: Provided is a plasma display panel (PDP) manufacturing technology, and more particularly, to a method for manufacturing an additive soft mold forming barrier ribs of a PDP and a method for forming barrier ribs of a PDP that can prevent camber and damage of a glass substrate, produce barrier ribs with uniform height, and make the soft mold separated easily. In this research, an additive soft mold is manufactured using an elastic rubber material, and barrier ribs of a PDP are formed by using the additive soft mold. In particular, the barrier rib paste can be filled by polishing the rear surface of the soft mold and forming an opening, using a squeezer instead of performing a pressing process. When a photopolymerizing photosensitive paste is used as a paste for forming barrier ribs, and it is exposed to UV light, the soft mold can be separated easily from the paste, because the polymer in the paste shrinks due to the polymerization reaction.
