Abstract: A multi-joint link hinge may include hinge bracket provided with a base in which a plurality of screw coupling holes are defined, a plurality of side walls which protrude from the base and are spaced apart from each other in a vertical direction, a plurality of link modules which are vertically arranged between the side portions and axially coupled to the hinge bracket by a rotation shaft, and a door bracket which is axially coupled to each of the plurality of link modules.

Abstract: The present invention relates to an air conditioner in which oils mixed in the refrigerant compressed by a plurality of compressors are separated together and recovered in an efficient manner. An air conditioner according to an embodiment of the present invention comprises: a plurality of compressors for compressing refrigerant; an oil separator connected to the plurality of compressors so as to separate oils mixed with the refrigerant compressed by the plurality of compressors; an oil discharge pipe connected to the oil separator so as to discharge the oils separated by the oil separator, and a plurality of oil recovery pipes branched from the oil discharge pipe so as to recover the oils separated by the oil separator to the plurality of compressors.

Abstract: An apparatus and method for constructing a data unit that includes a buffer status report (BSR) such that when BSR triggering is performed, the size(s) of the necessary sub-header(s) are also to be considered together in addition to the BSR size. There is a checking unit that checks whether any padding region is available in a MAC PDU that was constructed, a comparing unit that compares the number of padding bits with the size of a buffer status report (BSR) plus its sub-header, and a processing unit that cooperates with the checking unit and the comparing unit to trigger a buffer status report (BSR) procedure if the number of padding bits is larger than the size of the BSR plus its sub-header, including the BSR and its sub-header in the MAC PDU, and setting an LCID in the sub-header to indicate a BSR is included, the BSR having been triggered due to padding. Using such apparatus allows the sub-header(s) to be inserted (included) into the MAC PDU (or transport block (TB) or other data unit).

Abstract: A text subtitle decoder includes a text subtitle processor, a text renderer, and a presentation controller. The text subtitle processor parses a text subtitle stream into text data and reproduction control information, where the text data represent a subtitle text to be displayed within a text subtitle region. After the text subtitle stream is parsed, the text renderer renders the text data into bitmap data using the reproduction control information. The presentation controller controls operations of the text subtitle processor and the text renderer.

Abstract: The present invention relates to an image processing technique, and in particular to a method for restoring a compressed image by using a hybrid motion compensation discrete cosine transform (hybrid MC/DCT) mechanism, including: a step of defining a smoothing functional having a smoothing degree of an image and reliability for an original image by pixels having an identical property in image block units; and a step of computing a restored image by performing a gradient operation on the smoothing functional in regard to the original image, thereby preventing the blocking artifacts and the ringing effects in regard to the pixels having an identical property in image blocks. In one embodiment, the method includes obtaining a pixel value in a current block and at least one adjacent pixel value, obtaining a difference value between the pixel value in the current block and the adjacent pixel value, and obtaining a smoothing value of the current image based on the difference value.
