    • An antenna system for a vehicle is provided. The antenna comprises an antenna disposed on a window glass and having a feed point, a matching circuit connected to the feed point, and a coaxial cable connecting between the matching circuit and the radio receiver. The matching circuit includes a parallel circuit having a damping resistor, a first coil and a first capacitor. The matching circuit further includes a second coil and a second capacitor connected in series between an output side of the parallel circuit and a ground such that, assuming that MF1 is a lower limited frequency of medium-frequency (MF) broadcast waves and MF2 is an upper limited frequency of the MF broadcast waves, a receiving sensitivity of the antenna system has local maximum points which are present at a frequency F1 in the range from (MF1-170) to MF1 KHz and at a frequency f2 in the range from (MF2-230) to MF2 KHz, respectively, and a local minimum point which is present at a frequency f0 smaller than f1 and equal to or larger than 50 KHz.
    • 提供了一种用于车辆的天线系统。 天线包括设置在窗玻璃上并具有馈电点的天线,连接到馈电点的匹配电路以及连接在匹配电路和无线电接收器之间的同轴电缆。 匹配电路包括具有阻尼电阻器,第一线圈和第一电容器的并联电路。 匹配电路还包括串联连接在并联电路的输出侧和地之间的第二线圈和第二电容器,使得假设MF1是中频(MF)广播波的较低受限频率,而MF2是 MF广播波的上限频率,天线系统的接收灵敏度具有在从(MF1-170)到MF1KHz的范围内的频率F1处的局部最大点,并且在从(MF2 -230)分别为MF2KHz,局部最小点以小于f1且等于或大于50KHz的频率f0存在。

    • An apparatus for determining seat occupancy includes a seat for a vehicle, which has a seating portion, right and left load detecting portions arranged between a vehicle floor and either one of a front portion and a rear portion of the seating portion, the right load detecting portion detecting a load applied to a right side of the seating portion, the left load detecting portion detecting a load applied to a left side of the seating portion, and a seat occupancy determining portion calculating a seating load of the seat on the basis of the detected loads and determining the seat occupancy of the seat by comparing the seating load with a predetermined threshold value, wherein the seat occupancy determining portion varies the predetermined threshold value depending on of a difference value between the loads applied to the right and left sides, respectively, of the seating portion.
    • 一种用于确定座椅占用的装置包括一个车辆用座椅,其具有一个座位部分,左和右侧负载检测部分布置在车辆地板与座椅部分的前部和后部中的任一个之间,右侧负载检测 检测施加在座位部的右侧的负荷的部分,左负载检测部分检测施加在座位部的左侧的负荷,以及座椅占有率判定部,其基于 通过将所述就座负载与预定阈值进行比较来确定所述座椅的座位占有率,其中所述座位占有率确定部分分别根据施加到所述左侧和右侧的负载之间的差值来改变所述预定阈值 ,座位部分。
