Nissan Motor Co. says it will add sounds to the Leaf electric car to serve as a warning to pedestrians. The sounds are designed as a safety measure, given the fact that pure electric vehicles are nearly silent, even when they travel at fairly high speeds.
The Washington Post reports that Nissan explored more a hundred sounds ranging from chimes to artificial motor noises before settling on a soft whine that will increase with intensity as the car moves faster in forward gears. Nissan engineers reportedly have added a clanging sound to alert pedestrians when the vehicle backs up.
A Nissan statement explained the decision by saying, “While silence is golden, it does present practical challenges.”
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
