For example, we created this running sound with frequent gaps so that people with visual impairments could locate their robots using the Doppler effect.

例如，我们创建了这种带有频繁间隙的运行声音， 以便有视觉障碍的人可以使用多普勒效应定位他们的机器人。

The system would then measure with ultimate precision how long it takes the beams to be reflected back, and would then apply the Doppler effect in three-dimensional space to proceed safely.

然后，该系统将以极高的精度测量光束被反射回来所需的时间，然后将在三维空间中应用多普勒效应以确保安全进行。
