A device that stops drives from falling asleep at the wheel is about to undergo testing at Department of Transport laboratories and could go on sale within 12 months.
The system, called Driver Alert, aims to reduce deadly road accidents by 20%—40% that are caud by tiredness. Airline pilots can also u it to reduce the 30% of all pilot-error accidents that are related to fatigue.
Driver Alert is bad on a computerized wristband. The device, worn by drives or pilots, gives out a sound about every four minutes during a car journey. After each sound the drive
r must respond by squeezing the steering wheel(方向盘). A nsor in the wristband detects this pressing action and measures the time between the sound and the driver's respon.
Tiredness is directly related to a driver's respon time. Usually, a watchful driver would take about 400 milliconds to respond, but once that falls to more than 500 milliconds, it suggests that the driver is getting sleepy.非主流语言
In such cas the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver's respon continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.
The device has been delivered to the department's laboratories for testing. If the tests, scheduled for six months' time, are successful, the makers will bring the product to market within about a year.

Rearchers at the Babraham Institute in Cambridge, southern. England, have shown that animals have a good memory system and are extremely good at recognizing faces--which they think is a sure sign of intelligence.
Behavioral scientist Keith Kendrick and his friends trained 20 sheep to recognize and distinguish(区别) 25 pairs of sheep faces and ud electrodes(电极) to measure their brai
n activity, which showed they could remember 50 faces for up to two years.
"If they can do that with faces, the fact is that they have to have reasonable intelligence, otherwi, what is the point of having a system for remembering anything el," Kendrick said in an interview.
So hours of emingly mindless eating grass may not be so mindless after all.
