It is well-known that fatigue driving(疲劳驾驶)is very dangerous.A device that stops drivers 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 device is a kind of system, which is called Driver Alert,and it aims to reduce deadly road accidents by 20%—40%that are caused by tiredness.Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue.

    Driver Alert is based on a computerized wristband.The device,worn by drivers or pilots,gives out a sound about every four minutes during a car journey.After each sound the driver must respond by squeezing the steering wheel.A sensor in the wristband detects this pressing action and measures the time between the sound and the driver’s response.

    Driver’s response time is directly related to tiredness.Usually, a watchful driver would take about 400 milliseconds to respond,but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.   

    In such cases 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 response 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 these tests, scheduled for six months’ time,are successful,the makers will bring the product to market within about a year.

Last week when I was sitting in my office, I heard an elderly lady talking on the phone about her husband. Her husband’s name was Ed. He dropped her off for her doctor’s appointment and was going to park the car and wait for her. She was so upset that she started to cry. I knew I should take action.

The lady told me her name was Helen and she called the restaurant she and her husband were going to have lunch at after her appointment to see if he was waiting for her there. She explained that she thought her husband parked the car in the parking lot and waited for her in the car but she didn’t find him there so she returned to see if he entered the medical building, but Ed was not there either. She regretted making her husband park the car alone since some signs of Alzheimer’ (早老性痴呆症)had appeared in his behavior. I asked a few nurses to help look for Ed inside and out side the medical building according to Helen’s description. Then I offered to drive Helen to the restaurant to see if Ed was waiting for her there.

On arriving at the parking lot of the restaurant, Helen began to search for Ed’s car but she failed, which suggested Ed wasn’t there. We decided to have a talk with the manager before we returned to the hospital. On our way to the manager’s office, I received a call from a nurse, who said they had found Ed. What a relief(安慰)! But we still needed to go on searching since he forgot where he parked his car! Fortunately, we didn’t have much difficulty finding it.

As I waved goodbye to the couple, I thought, “This is true love in life. The love is not romantic but it stays with us all the time.”
