1.   Our central sensors would detect any ship coming in from five thousand li out.

2.   Although infrared light cannot be seen by the human eye, it can be detected by sensors designed to measure the radiation frequencies below the visible range.

3.   An fMRI sensor detects and records those radio pulses.

4.   As a result, the sensor often detected targets where none existed.

5.   As passengers approach, infra-red sensors detect their presence, activating tiny fans in the roof, which then force air through fragrance-soaked pads.

6.   A laser sensor detects the minute surface vibrations, which are recorded by a computer and used to pinpoint the location of the mine.

7.   If the sensor detects smoke or heat seeping into the lower chamber, it triggers the transmitter to send a signal to a remote receiver.

8.   It has a low gear range for severe conditions, but for regular driving, the rear wheels get the power until sensors detect slippage.

9.   It activates only when sensors detect that the heart is out of rhythm, a condition known as ventricular fibrillation.

10.   Officials at the lab said no buildings containing radioactive materials had been damaged and that their sensors had detected no radiation leaks.
