Abstract: An encoding/decoding apparatus and method for controlling a channel signal is disclosed, wherein the encoding apparatus may include an encoder to encode an object signal, a channel signal, and rendering information for the channel signal, and a bit stream generator to generate, as a bit stream, the encoded object signal, the encoded channel signal, and the encoded rendering information for the channel signal.

Abstract: A display apparatus according to a concept of the disclosure includes: a display panel configured to display an image in a front direction; a top chassis positioned in a front direction of the display panel; a bottom chassis positioned in a rear direction of the display panel; a rear cover covering a rear side of the bottom chassis; and a stand member being accommodatable in the rear cover and selectively coupled with a rear surface of the rear cover, wherein the rear cover includes an accommodating portion in which the stand member is accommodated and a coupling portion coupled with the stand member, and the stand member includes an inserting protrusion which is inserted into the accommodating portion and the coupling portion.

Abstract: The present disclosure relates to an apparatus for preparing an oligomer, the apparatus including: a reactor for oligomerizing a feed stream containing a fed monomer; a stirrer inserted into a hole formed in an upper portion of the reactor; and a solvent transfer line extending inward from a side of the reactor, wherein the stirrer includes a rotating shaft vertically extending downward from the upper portion of the reactor, and a blade having a conical shape whose vertex is positioned at a lower end of the rotating shaft and outer diameter increases from a bottom toward a top, and the solvent transfer line has a plurality of spray nozzles formed in a direction toward the blade.

Abstract: Disclosed is an apparatus and method for processing a multichannel audio signal. A multichannel audio signal processing method may include: generating an N-channel audio signal of N channels by down-mixing an M-channel audio signal of M channels; and generating a stereo audio signal by performing binaural rendering of the N-channel audio signal.

Abstract: Disclosed is a catheter for the extraction of foreign substances from blood vessels including an insertion tube configured to be inserted into a blood vessel and provided at one side thereof with a branched suction tube, a moving crusher configured to be inserted into the blood vessel while being received inside the insertion tube, the moving crusher serving to crush foreign substances inside the blood vessel after being discharged out of the insertion tube, and a foreign substance moving net coupled to a front end of the moving crusher so as to guide the crushed foreign substances into the insertion tube, the foreign substance moving net having a mesh shape.

Abstract: An apparatus and method of automatic router configuration is disclosed when a cable of the router in operation is replaced or a protocol configuration is changed, a PLD automatically senses the change and initializes parts of the system to normalize communication environments without turning off the power. A TVS circuit is provided to absorb and prevent an electrical shock so that cable replacement is made possible in the power-on state.

Abstract: The present invention relates to anti-adhesion barriers which prevents an adhesion between tissues at an operated legion and have various shapes, comprising sodium carboxymethyl cellulose (NaCMC) and gellan gum in 1:(0.1˜10) of weight ratio.
