Abstract: An apparatus for controlling a vehicle is introduced. The apparatus may comprise at least three different type of sensors. The first sensor may obtain visual track information about an external object within an image. The second sensor may provide track information in the form of plots corresponding to the external object. The third sensor may collect track information in clusters of points or virtual boxes corresponding to the external object. The apparatus may set a reference angle range and distance based on the first and second track information. The apparatus then may associate these with the third track information and output a signal for vehicle control.

Abstract: The present disclosure provides a grinding wheel for grinding, configured such that a fiber-reinforced plastic (FRP) layer in a wheel outer peripheral part located on the outer surface of a wheel central part is provided at a position and thickness that vary depending on the type of weaving pattern layer, thereby exhibiting superior mechanical properties and superior vibration/shock absorption and offsetting effects compared to conventional grinding wheels, so problems such as cracking and fatigue failure due to burning do not occur, and the quality and productivity of processed products can be improved. Moreover, the grinding wheel is lighter in weight than conventional grinding wheels, and when an abrasive part is completely consumed, it can be replaced with a new abrasive part through removable attachment thereof, whereby the wheel outer peripheral part (wheel body) can be reused continuously, and the exchange time and the amount of tool wear can be reduced.

A first eNodeB (eNB) of an energy saving cell configures a list of minimum required evolved-UMTS terrestrial radio access network (E-UTRAN) radio access bearers (E-RABs) or required E-RABs, and transmits the configured list of minimum required E-RABs or a required E-RABs to a second eNB of a compensation cell. Upon receiving the configured list of minimum required E-RABs, the second eNB checks whether the compensation cell is able to provide all E-RABs included in the list of minimum required E-RABs or not. Upon receiving the configured list of required E-RABs, the second eNB checks whether the compensation cell is able to provide E-RABs included in the list of required E-RABs or not.
