When a sleepy driver has trouble in keeping his eyes on the road and gets too close to another car, an alarm sound will warn the driver. If nothing is done, the car will automatically come to a stop and in this way prevent an accident. This is a new device which will soon be tested in an experimental car in Japan. The computer warning system keeps track of a driver’s condition by monitoring his heart beat with signals transmitted from a band round his wrist, The wrist band records the driver’s pulse which measures the heart beat. Each pulse in the wrist sends a signal to the computer. By analyzing the pulse rate, the computer can determine whether a driver is drunk, sleeping or ill. Devices in other parts of the car can also tell the computer if the car is too close to another vehicle or is moving dangerously. The computer will sound the alarm when a problem arises, and will automatically stop the car ff the driver ignores the warning.
选项
A、It monitors the signals transmitted from the driver’s brain.
B、It can measure the driver’s alcohol level in the blood.
C、It can quicken the driver’s response to emergencies.
D、It bases its analysis on the driver’s heart beat.
答案
D
解析
信息判断题。这种新型的电脑控制系统通过戴在司机腕部的监测器监测司机的脉搏心跳,然后对司机当时的状况进行分析,鉴定司机是否酗酒、困倦或是生病。分析的根据主要就是脉搏心跳(heart beat,pulse rate)。这也是这种新型的电脑控制系统的特别之处。
