Abstract: A refrigerator includes a driving coupler to transmit a driving force and a connecting member to transmit the driving force of the driving coupler to a transfer member. The connecting member is rotated when interference with the driving coupler occurs in a process of connecting with the driving coupler and idles within a predetermined angle range regardless of the transfer member. With this constitution, even when ice cubes are loaded by the transfer member, the connecting member may be smoothly rotated. Thus, the driving coupler and the connecting member may be smoothly connected without an impact.

Abstract: Algorithms and concepts for maintaining uniform random samples of streaming data and stream joins. These algorithms and concepts are used in systems and methods, such as wireless sensor networks and methods for implementing such networks, that generate and handle such streaming data and/or stream joins. The algorithms and concepts directed to streaming data allow one or more sample reservoirs to change size during sampling. When multiple reservoirs are maintained, some of the algorithms and concepts periodically reallocate memory among the multiple reservoirs to effectively utilize limited memory. The algorithms and concepts directed to stream joins allow reservoir sampling to proceed as a function of the probability of a join sampling operation. In memory limited situations wherein memory contains the sample reservoir and a join buffer, some of the stream join algorithms and concepts progressively increase the size of the sampling reservoir and reallocate memory from the join buffer to the reservoir.

If the vehicle speed exceeds the speed limit of a road, the vehicle speed is automatically reduced to below the speed limit, and a warning operation is performed. Thereby, probability of accidents due to speeding may be reduced, and it may be possible to make the driver obey the Road Traffic Act and to prevent imposition of fines due to speeding. Further, the vehicle speed is automatically reduced at bumps or curves, resulting in enhanced safety and driver convenience.
