作为结果，噪音提高了开关的灵敏度——这种现象叫做随机共振。
In effect, the noise increases the sensitivity of the switch - a phenomenon called stochastic resonance.
用单位增益缓冲器构成的开关电容滤波器（SCF），若能消除寄生电容引起的“阻性”寄生，则可用于高频设计，总寄生灵敏度会因此大大降低。
The unity gain buffer will be good for designing high frequency SCF if its resistive effect can be eliminated and then the overall parasitic sensitivity will be greatly lowered.
自动缝纫，采用高灵敏度光纤传感器自动启动缝纫机，无需脚踩开关。
Machine used high sensitivity optical fiber sensor. Automatic sewing without manual step On/Off.
