Abstract: Provided are a network system supporting a spanning tree protocol (STP), a relay apparatus thereof, and a method of creating a spanning tree. Proposed is a method of creating a tree topology, between AVB bridges, using a STP message including a group MAC address which is different from that used in a non-AVB (Audio Video Bridging) bridge (that is, a bridge without the function of AVB), in order to form a minimum number of AVB clouds. Therefore, it is possible to efficiently ensure transmission quality of a multimedia stream such as an AVB stream.

An upper arm is coupled, through a joint, to one side of the operating unit. A forearm coupled, through a joint, to the other side of the upper arm by the cable. A gripper of an end effector operably coupled to the forearm, a cable compensation device is installed between the upper arm and the forearm so as to maintain constant the length of the cable that transmits the power of the operating unit to the end effector during the pivoting of the forearm. It is thus possible to prevent the variation of tensile force due to the variation of the length of the cable for operating the end effector during the pivoting of the forearm or the unintended malfunction of the end effector.

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.

Abstract: Disclosed herein is an adaptive cruse control method on an incline to improve traveling performance and stoppage maintenance performance on an incline. During adaptive cruise control, a gradient of a road is estimated based on a vehicle acceleration and longitudinal acceleration to enable compensation of a resistance torque with respect to the gradient of the road, which prevents deterioration of a traveling speed of a vehicle on an incline. Also, compensating for a brake torque to prevent the vehicle from being pushed rearward when the vehicle is stopped or starts to go on an incline may prevent deterioration of performance on an incline.
