所以O'Brien先生一直研究一套基于天花板的系统，用于跟踪接收装置所在位置，利用来自定向传送器的几束激光向该装置发出信号。

So Mr O'Brien has been working on a ceiling-based system that tracks where a receiving device is, and then sends it a signal using several laser beams from a directional transmitter.

如果机器和人都没有接收到他们需要的信息，即使拥有最大功率的激光机和最有效的原材料处理系统也是无济于事的。

The most high-powered laser and efficient material handling system don’t count for much if both machines and people can’t access the information they need.
