摘要:
According to an embodiment of the present invention, a torque variation of a servomotor, which is measured in a numerical control apparatus of an existing numerical control machine tool, is observed, and a backlash is detected by calculating a transfer distance of an output shaft of the servomotor at a torque peak, without adding additional positioning detection equipment, thereby detecting an accurate backlash amount without adding additional equipment.

Total global minimum costs can be determined for multiple sub-plans for completing a multi-operation database process to be performed in a distributed database management system that includes a plurality of nodes. The multiple sub-plans can include different distributions of node locations of a plurality of operators among the plurality of nodes. An optimal plan having a lowest total minimum global cost can be selected from the multiple sub-plans.

There is a need for a window blind assembly for a vehicle, in which vibration and noise are reduced when a shade curtain moves and which is convenient to be transported. The window blind assembly for a vehicle includes: a main frame; a pair of connection units arranged in the main frame; a rotary shaft rotationally arranged in the connection units; a pair of guide rails rotationally arranged in the connection units and formed with guide grooves; a shade curtain supporter movably coupled to the guide grooves of the pair of guide rails; a shade curtain including one side end portion connected to the rotary shaft and rolled into the rotary shaft, and the other side end portion connected to the shade curtain supporter and unrolled as the shade curtain supporter becomes apart from the rotary shaft; and a driving unit providing driving force to move the shade curtain supporter along the guide rail.

There is provided a channel access method in which a channel access method in a wireless network in which a channel access opportunity is provided to high priority traffic for each super-frame. The channel access method includes: setting parameter values required for channel access; setting a channel access time to be equal to a size of a contention access period (CAP); and accessing a channel to be used by resetting the channel access time to be equal to the size of the CAP when traffic to be transmitted is traffic having a preset high priority in a case in which the channel is not in an idle state.
