Abstract: An ice bank of an ice-making device for a refrigerator is disclosed, for smooth crush and discharge of ice, which includes a housing for storing ice made in an icemaker, and provided rotatably to apply the power to the stored ice at a rotation direction; an ice discharger having at least one hole through which the ice is discharge to the external; a crusher provided in the inside of the housing, the crusher guiding the stored ice to the hole of the ice discharge and crushing the ice as a predetermined size before discharging the ice to the hole according to a user's select; and rotating means for rotating the housing. Also, the crusher includes fixed crushing means fixed to the inside of the housing, and rotation crushing means rotated for being synchronized with the housing so as to crush the ice before discharging the ice to the external according to a user's select.

Abstract: A coordinator switching method and a communication system using the same, which can promptly replace the present coordinator with another device if an unexpected situation happens so that the present coordinator cannot suddenly broadcast a sync signal in the ad-hoc network environment. The coordinator switching method includes selecting a coordinator that broadcasts a sync signal for synchronizing the ad-hoc network environment, selecting at least one of a plurality of devices linked to an ad-hoc network as a replacement coordinator and setting a priority of the selected replacement coordinator, transmitting the priority to the selected replacement coordinator, and if the sync signal is not broadcast for a predetermined time, the replacement coordinator becoming a new coordinator in accordance with the set priority to broadcast the sync signal.

Abstract: An icemaker for an ice supply system for preventing water from overflowing from the ice tray by vibration and/or shaking of the surrounding structure includes an icemaker, a container provided at a lower part of the icemaker and an ice chute for supplying the ice stored in the ice container. An ejector in the ice tray of the icemaker and a dropper device having an inclined upper surface at a side of the open top of the ice tray are provided for dropping the ice discharged upwardly by the ejector. An overflow prevention device is provided at another side of the open top of the ice tray for preventing water filled in the ice tray from overflowing. The overflow prevention device includes a panel extending upward from the ice tray and a cover coupled with the hinge at the top of the ice tray.

Abstract: Disclosed is a structure for dispensing ice in a refrigerator, in which an automated ice-making device and an ice bank are installed at a door of a freezing chamber to thereby make its space utilization effectively. The structure of the present invention includes: an ice-making device installed in a door of a freezing chamber; an ice bank storing pieces of ice provided from the ice-making device; an ice transfer unit for transferring the pieces of the ice stored in the ice bank in a width direction; and an ice crushing part for crushing the pieces of the ice transferred by the ice transfer unit.

Abstract: A computer mouse having data recording and decoding function is comprises a card inserting part for inserting a memory card in a body of the computer mouse, an output part for reading and outputting data stored in the memory card, and a Moving picture experts group decoding part to control storing and decoding data by cooperating with the card inserting part having a memory card and the output part. Thereby, a moving picture experts group decoder or MP3 player can be affixed within the same body of a computer mouse or can be easily mounted on the top of the computer mouse. Therefore, a connecting means like a cable does not need to store data in a memory card. And the data can be played without any other MPEG decoder.

Abstract: Disclosed is to a cellular phone which is compatible with an MP3 player, which is detachably inserted to a battery of the cellular phone, and can be used for an audio player by connecting to the battery with the MP3 player, so that it is convenient for a user to use the MP3 player without the increasing weight and the size of a main body to the cellular phone.
