COMMUNICATION SYSTEM AND METHOD FOR CONTROLLING COMMUNICATION SYSTEM - A simplified explanation of the abstract

  • This abstract for appeared for US patent application number 18022932 Titled 'COMMUNICATION SYSTEM AND METHOD FOR CONTROLLING COMMUNICATION SYSTEM'

Simplified Explanation

The communication system described in the abstract aims to prevent communication issues and signal overlap among multiple slave devices. It involves a first master device that sends out a pulsed light through a transmission path and receives the reflected light from a second transmission path. Each slave device modulates the pulsed light and sends it back as the reflected light. The width of the pulsed light is narrower than twice the shortest distance between the slave device and the first master device or between the slave device and the first master device.


Original Abstract Submitted

In order to avoid the phenomenon of communication being impeded and signals transmitted by the plurality of slave devices overlapping, a communication system according to the present invention has the first master device transmits a first pulsed light to the first transmission path and receives a return light of the first pulsed light from the second transmission path; each of the slave devices modulates the first pulsed light, and outputs the modulated first pulsed light as the return light of the first pulsed light; and the width of the first pulsed light is narrower than double the shortest distance from among the transmission distance between the slave device outputting the return light and the transmission distance between the first master device and the slave device outputting the return light.
