  • Patent number: 8434320
    Abstract: Disclosed is a dispenser of an icemaker in a refrigerator for maximizing an inner space when a total size is the same, and for minimizing the total size when the inner space is the same. The dispenser of the icemaker in the refrigerator includes an ice chute being a passage through which the ice produced from the icemaker is discharged; and a container supporter provided at an outer case and disposed to be perpendicular to an outer surface of the outer case when the ice is discharged outside through the ice chute, the contain supporter allowing a container seated thereon to receive the ice discharged from the ice chute. The ice chute is closed and not exposed outside when the ice-discharging process is finished, and the container supporter is not exposed to the outer surface of the outer case.

  • Patent number: 8249131
    Abstract: A method for transmitting signals for interference randomization is disclosed. The method for transmitting signals includes spreading the transmission signals using a plurality of orthogonal codes and transmitting the transmission signals spread by the plurality of orthogonal codes by a spatial frequency block coding (SFBC) or spatial time block coding (STBC) scheme. Among the plurality of orthogonal codes, codes of which mutual interferences are equal to or greater than a predetermined threshold are grouped to the same group, and orthogonal codes belonging to different groups are used for the spreading of the signals which are transmitted at the same timing. Accordingly, it is possible to realize interference randomization.
