一些动物的胡须可以帮助它们在光线不好的地方探路。英国研究人员受此启发,发明出一种防撞感应头箍。这种头箍的外围一周安装有多个小型感应器,感应器探测到的信息通过电线传递给一台随身电脑,电脑对这些信息进行分析处理后会即时将信号传回头箍。如果周围有障碍物,信号就会激活头箍内侧的一条震动带,提示佩戴者注意危险。 Some animal beards can help them find ways in poor light. Inspired by British researchers, invented a collision-resistant headband. Around the periphery of this headband, there are several small sensors installed. The signals detected by the sensors are transmitted by wires to a portable computer. The computer analyzes the information and sends the signals back to the headband immediately. If there are obstacles around, the signal activates a vibration band inside the headband, alerting the wearer to danger.
