German scientists have invented a device designed to prevent motorists from falling asleep at the wheel which could save 300,000 lives a year around the world. The system devised at the Fraunhofer Institute for Digital Media Technology involves tiny cameras that monitor eye movements which trigger an alarm when drivers seem about to nod off.
德国科学家近日发明一种能够“防止司机开车时瞌睡”的监视器，据悉，这一新发明一旦问世，每年可以“拯救”30万民众的生命。，司机一旦打盹，眼皮的活动会通过传感器告诉设备，并发出尖锐的警报声。
Professor Peter Husar of the institute said: What we have developed is a small modular system with its own hardware and programmes on board, so that the line of vision is computed directly within the camera itself.
发明此设备的教授Peter说，该设备属于自带存储命令的模块化系统，。
