摘要： A method for measuring a position, is performed by a vehicle assembly (VA) for alignment between a ground assembly (GA) and the VA. The method includes transmitting low frequency (LF) signals to initiate alignment with the GA and estimating a position of a vehicle using at least one sensor mounted on the vehicle. Information regarding the estimated position of the vehicle is provided to the GA and information regarding a position of the vehicle measured by LF receive antennas of the GA and an acceleration flag calculated by the GA is received. Accordingly, a transmission strength of the LF signals transmitted by the VA is adjusted based on the information regarding the position of the vehicle measured by the LF receive antennas and the acceleration flag.

摘要： Provided is a semiconductor device. The device comprises an epitaxial layer that constitutes a part of an active cell region and is doped with impurities of a first conductivity type at a first concentration; a field stop region that is located below the epitaxial layer and doped with impurities of a second conductivity type at a second concentration which are then activated; and a collector region that is located below the field stop region 70 and is doped with impurities of a second conductivity type. The field stop region is formed by repeatedly alternately arranging regions in which the activation of the impurities of the first conductivity type is relatively strong and regions in which the activation of the impurities of the first conductivity type is relatively weak.
