A refrigerator includes a main body having a storage chamber within the main body; and a door. The door includes: a door body having insulation inside the door body, the door body being rotatably coupled to the main body so that the door is rotatable to open and close the storage chamber; a door panel which detachably coupled to the front of the door body and forming a front surface of the door; a trim installing classis which is detachably mounted to the door body so as and forming a side surface of the door, the trim installing chassis includes a trim coupling portion protruding outward from the door body and the door panel; and a deco trim which is mounted to the trim coupling portion and forming an edge of the door, wherein the door panel and the deco trim together form a front outer appearance of the door.

Refrigerator

Provided is a refrigerator including a main body including a storeroom, a door body arranged to open or close the storeroom, a decoration panel coupled to a front side of the door body, and a holder mounted on the front side of the door body to be coupled to the decoration panel. The door body includes a rear case defining a rear side of the door body, and a main case defining front and sides of the door body. The main case includes a front part defining the front side of the door body and having an installation groove in which to install the holder, side parts defining sides of the door body, and a rear coupler coupled to the rear case. The main case is formed by bending a single metal board.

A refrigerator including a main body having a storage room, and a door to open and close the storage room, wherein the door includes a door body and a door panel detachably mountable on the door body. The door panel may be installed on the door body by coupling a lower fixing portion with a lower cap protrusion, accommodating an upper fixing portion in an accommodating space through a panel passing portion, and accommodating a fixing cover in the accommodating space through a cover passing portion to be coupled with the upper fixing portion.

A residual echo estimator estimates a residual echo of a microphone signal input to a microphone as a reference signal is output through a speaker. The residual echo estimator estimates a magnitude of a residual echo of the reference signal at a current frame by using a magnitude of the linear echo of the reference signal at the current frame and a magnitude of the linear echo of the reference signal at a past frame, and updates weights to be applied to the magnitudes of the linear echo.

Disclosed is a method and a system for preventing a call drop by limiting a search time for a 1X system during a 1xEV-DO system traffic state. The system comprises a hybrid access terminal, supporting both a 1xEV-DO system and a 1X system, for periodically switching over to the 1X system while in traffic with the 1xEV-DO system, updating an overhead message, checking a search time and switching over to the 1xEV-DO system based on a result of the search time; a base station transceiver subsystem including a 1xEV-DO transceiver subsystem for exchanging a packet data with the hybrid access terminal and a 1X transceiver subsystem for exchanging a voice or data with the hybrid access terminal; a base station controller including a 1xEV-DO controller for controlling a packet data transmission service of the 1xEV-DO transceiver subsystem and a 1X controller for controlling transmission service of the 1X transceiver subsystem; and a packet data serving node connected to the 1xEV-DO controller for exchanging the packet data with the 1xEV-DO system.
