Abstract: A handover method of a first terminal in a wireless communication system may comprise: transmitting a first measurement report message to a first cell that is a primary cell (PCell); receiving, from the first cell, one or more first configuration messages for one or more target cells determined according to the first measurement report message; adding each of the one or more target cells as a candidate PCell based on the one or more first configuration messages; and performing data transmission and reception with at least one cell among the first cell and the one or more candidate PCells.

Abstract: A refrigerator comprises: a body having a storage chamber; a door for selectively shielding the storage chamber; a hinge coupling portion for hinge-coupling the door to the body; and a height control unit for lifting up or lowering the door by repeatedly opening and closing the door. Since the door has a controllable height by being opened and closed, a moment arm becomes longer than when using the conventional tool such as a spanner. This may allow the height of the door to be controlled by using less force. Since the height of the door is controllable at a user's eye height, the user may control the height of the door more rapidly and precisely without errors.

Abstract: Method for preventing formation of ice on a damper in a refrigerator, comprising the steps of (1) driving a compressor and a fan and opening baffles if a freezing room temperature is lower than a freezing room reference temperature and a chilling room temperature is lower than a chilling room reference temperature, (2) comparing the chilling room temperature to the chilling room reference temperature, to close the baffles if the chilling room temperature is lower than the chilling room reference temperature, (3) comparing the freezing room temperature to the freezing room reference temperature, to stop the compressor and the fan if the freezing room temperature is lower than the freezing room reference temperature, (4) comparing an outside temperature of the refrigerator to an outside reference temperature, to return back to the step (1) if the outside temperature of the refrigerator is higher than the outside reference temperature, and determining chilling room door of being opened if the outside temperature

Abstract: A concentrated cool air supply device for refrigerators is disclosed. In the device, a branch duct is branched from the cool air passage to guide the cool air to the door. A door duct is formed on the door to receive the cool air from the branch duct. The door duct has a plurality of air outlet openings on a cover plate. The outlet openings of the door duct are selectively opened by a slide panel, thus concentrically discharging the cool air from the door duct into a desired portion of the compartment. In order to move the slide panel, the device also has a motor, a rotatable link and a connecting rod. The link is coupled to the motor, thus being selectively rotated by the motor, while the connecting rod is connected to the link and the slide panel at both ends.

Abstract: A cool air supplying device for a fresh food compartment in refrigerators is disclosed. In the device, a cool air passage extends from an evaporator to the fresh food compartment. A connection duct is branched from the passage and extends to a front portion of the fresh food compartment. A plurality of door ducts are provided on the door of the fresh food compartment and individually have an air inlet opening at a position selectively aligned with an associated one of the air outlet openings of the connection duct. The door ducts also have a plurality of air outlet ports capable of discharging cool air from the door ducts into the fresh food compartment rearwardly. The amount of cool air for the air outlet openings of the connection duct is controlled by a cool air distribution unit. The air distribution unit has a motored regulator.

Abstract: An apparatus for and a method of supplying cold in a refrigerator, wherein respective temperatures at a plurality of different portions of the interior of the refrigerator are sensed so that cold air is selectively supplied to each refrigerator portion based on the sensed temperature associated with the refrigerator portion, thereby effectively maintaining the refrigerating and freezing compartments of the refrigerator at predetermined temperatures, respectively.
