The idea then, is to design “sensor systems that can enter living cells and complex environments and remain in an ‘off’ state until exposure to a target leads to a [signal].

根据方案，将如此设计：敏感元件系统能记录活细胞并在复杂环境下保持关闭状态，直到接收到目标型号。

If the running system has many instances of the same kind (say, an interface graphical element in an IT system or a sensor message), each will have the same state model.

如果运行系统有许多同样种类的实例(比方说，IT系统或传感器消息中的界面图形元素)，每个都将有相同的状态模型。

The app spends roughly a week collecting data from this sensor and testing it against the user's emotional state.

That might be about to change, though, as South Korea's state-owned Korea Electronics Technology Institute has announced a new image sensor chip that promises to take "vibrant photos" in extreme low-light conditions -- all the way down to 1 lux, which is the equivalent light output of a candle shining one meter away.

By combining a state-of-the-art image processing engine and back-illuminated CMOS image sensor with low-noise, even up to ISO 6400, and approximately 16.0 effective megapixels, the PENTAX X-5 provides users with very high-resolution images.
