    • A switching circuit and a DC-DC converter including the same are provided. The switching circuit includes an output terminal, a plurality of input terminals, and a plurality of switches configured to selectively connect the plurality of input terminals to the output terminal. The plurality of switches include a first switch directly connected to the output terminal and a plurality of second switches connecting the plurality of input terminals to the first switch. The first switch is implemented using a high-voltage transistor. Each of the second switches is implemented using a low-voltage transistor. A gate of the high-voltage transistor is at least two times longer than a gate of the low-voltage transistor. The DC-DC converter increases or decreases a signal selected from among a plurality of input signals input through the input terminals by a predetermined voltage level. Most of switches in the switching circuit are implemented using low-voltage transistors, thereby decreasing the area of the switching circuit.
    • 提供一种开关电路和包括该开关电路的DC-DC转换器。 开关电路包括输出端子,多个输入端子以及被配置为将多个输入端子选择性地连接到输出端子的多个开关。 多个开关包括直接连接到输出端子的第一开关和将多个输入端子连接到第一开关的多个第二开关。 第一个开关是使用高压晶体管实现的。 使用低压晶体管来实现每个第二开关。 高压晶体管的栅极比低压晶体管的栅极长至少两倍。 DC-DC转换器将从输入端子输入的多个输入信号中选出的信号增加或减少预定的电压电平。 开关电路中的大多数开关使用低压晶体管来实现,从而减小开关电路的面积。

    • A set of reference moisture value of the plurality of sample skin is measured with conventional skin moisture measuring device. Then a set of standard calibration equation is provided from calculating a set of measured reflectance spectra of calibration and the set of reference moisture value by using the multivariate regression, and it is stored at a memory. The next steps are to measure skin moisture of test skin with reference to the set of standard calibration equation stored at the memory. By radiating near infrared on the test skin and sensing a set of reflectance spectra with the portable skin moisture measuring apparatus by using near infrared reflectance spectroscopy system, the skin moisture is measured at a repeatable and stable way, regardless of the variation of temperature or humidity of the external circumstance.
    • 使用常规的皮肤水分测量装置测量多个样品皮肤的一组参考水分值。 然后通过使用多元回归从计算校准的一组测量反射光谱和参考水分值集合来提供一组标准校准方程,并将其存储在存储器中。 参考存储在存储器中的标准校准方程组,下一步是测量皮肤的皮肤水分。 通过在测试皮肤上辐射近红外线,并通过使用近红外反射光谱系统,利用便携式皮肤水分测量装置感测一组反射光谱,不管温度或湿度的变化如何,以可重复和稳定的方式测量皮肤水分 的外部环境。
