路器───Road device;裸器件───Bare device
It all sounds rather worrying, but so far there has been no known case of a cyber-attack in which a car has been forced off the road or a medical device misappropriated.───这一切听起来都让人很担心，但是，到目前为止，还没有发生过汽车离开道路，或者医疗设备不正当使用的网络攻击事件。
That used to be a simple device, working like a radio-frequency identification tag when it passes under a gantry on a toll road, but it is also getting smarter.───这个车载单元只是一个简单的装置，当车辆通过收费公路入口处时，这个装置就起到了一个无线电频率身份识别标签的作用，但这个装置也开始实现智能化了。
For example, a device can switch transparently from GPRS on the road to a cheaper WLAN in an Internet cafe for network connectivity, depending on location input from a GPS module.───例如，根据GPS模块的定位输入，设备可以透明地将网络连接从路上的GPRS切换到网吧中更便宜的WLAN。
