    • A vision enhancement device for use in a vehicle that improves the frontward vision of an operator during operation. The device has two dividing lines set apart from each other on an instrument panel. These dividing lines show as false image lines on an inside surface of a front window, and divide the inside surface of the front window into a plurality of areas in a vertical direction. A second area formed between these two false image lines forms an appropriate visual field range when the operator looks forward while operating the vehicle. First light emitting means comprising light emitting diodes are disposed at both ends of each of the two dividing lines. The light emitted by these light emitting diodes is directed onto the front window as a false image in accordance with changes in the vehicle state and the environment around the vehicle.
    • 一种在车辆中使用的视觉增强装置,其改善操作者在操作期间的向前视力。 该设备在仪表板上具有彼此分开的两条划分线。 这些分割线在前窗的内表面上示出假图像线,并且将前窗的内表面分成多个垂直方向的区域。 形成在这两条虚假图像线之间的第二区域在操作车辆时操作者向前看时形成适当的视场范围。 包括发光二极管的第一发光装置设置在两条分割线中的每一条的两端。 由这些发光二极管发出的光根据车辆状态的变化和车辆周围的环境而被引导到作为假图像的前窗上。

    • Switching member SW20 which receives detection signals for detecting capacitance outputted from a control part 35, controls each of switches so as to measure capacitance between electrodes positioned adjacently (an electrode TE1 and an electrode TE2, and so on) before measuring capacitance of measuring object. Capacitance initially measured between the adjacent electrodes are stored in a storing circuit 30. The initial capacitance are averaged to calculate an averaged initial value. Upon calculating the averaged initial value, correction values which represent difference between the averaged initial value and the initial capacitance are calculated. Actual measured values are corrected using the correction values when level of measuring object is measured. It is therefore possible to measure level of measuring object without influence of floating items or the like with stability, because level measurement is conducted by utilizing capacitance measured between adjacent electrodes. Also, actual measured values are corrected with the corrected value after measuring initial values. Therefore, level measurement of the measuring object can be conducted with high stability and accuracy.
    • 接收检测从控制部35输出的电容的检测信号的开关部件SW20,在测量对象物体的电容量之前,控制每个开关以测量邻近的电极之间的电容(电极TE1和电极TE2等)。 最初在相邻电极之间测量的电容被存储在存储电路30中。初始电容被平均以计算平均的初始值。 在计算平均初始值时,计算表示平均初始值和初始电容之间的差的校正值。 当测量对象的电平时,使用校正值校正实际测量值。 因此,可以通过利用在相邻电极之间测量的电容来进行电平测量,从而可以稳定地测量测量对象的水平而不影响浮动物品等。 此外,在测量初始值之后,用校正值校正实际测量值。 因此,能够以高稳定性和精度进行测量对象的液位测量。
