    • A method and apparatus for measuring the remaining charge of a galvanic cell effects the measurement of the remaining charge by superimposing an AC voltage or current on DC voltage or current issuing from the cell to produce a higher harmonic current or voltage, determining the value corresponding to a higher harmonic component of n'th order from the higher harmonic current or voltage, and comparing the value thus measured of the cell under test with that measured previously in the same manner of a reference galvanic cell. Since the corresponding value of the higher harmonic current or voltage of n'th order varies notably with the decrease in the remaining charge of the galvanic cell, the comparison of the found corresponding value with the reference characteristic is effected with ease and the measurement can be carried out accurately and simply.
    • 用于测量电池的剩余电荷的方法和装置通过将AC电压或电流叠加在从电池发出的DC电压或电流上产生高次谐波电流或电压来实现剩余电荷的测量,从而确定对应于 从高次谐波电流或电压起n阶的高次谐波分量,并将与测得的电池相同的值与先前参考电流电池相同的方式进行比较。 由于高次谐波电流或第n阶电压的对应值随着原电池的剩余电荷的减少而显着变化,因此可以容易地实现所找到的对应值与参考特性的比较,并且测量可以 精确而简单地进行。

    • The invention relates to an area lighting device using an LED as a light source and a liquid crystals display having the same. An object is to provide an area lighting device which can provide stable display quality and a liquid crystal display device having the same. An area lighting device is configured to have a light source part provided with a plurality of LEDs; a dummy liquid crystal panel which has a pair of substrates and a liquid crystal layer encapsulated between the substrates, and to which light from the light source part partially enters; a chromaticity sensor which senses a chromaticity of light transmitted through the dummy liquid crystal panel; and an LED control part which compares the sensed chromaticity with a set target value, and controls the plurality of the LEDs so that the chromaticity becomes close to the target value.
