Radio-enabled collision avoidance system

摘要

In the method of reducing the likelihood of collisions, the improvement comprising the step of embedding passive radio transponders in a tape, grease, or other materials; applying said passive radio transponders to an object of which collisions must be avoided, and mounting an active interrogating transponder on a moving machinery, which uses the information provided by the radio transponders to semi-autonomously avoid collisions.

1. A system for avoiding collisions between an object and one or more parts of a moving machinery, the system comprising:
a material attached to the object, wherein the material is embedded with one or more passive radio transponders; wherein the one or more passive radio transponders passively modulate the received radio frequency pulses; and wherein the one or more passive radio transponders send return signals having a frequency different from that of the received radio frequency pulses; one or more active interrogating transponders mounted on the one or more parts of the moving machinery, wherein the one or more active interrogating transponders transmit wideband radio frequency pulses and receive multiple return signals from each of the one or more passive radio transponders and integrating multiple return signals by a single active interrogating transponder upon receiving multiple return signals corresponding to a particular passive radio transponder; and a semi-autonomous controller coupled to the moving machinery and configured for semi-autonomously controlling the movement of the moving machinery or the one or more parts of the moving machinery based on the distance between the object and the moving machinery or the one or more parts of the moving machinery, wherein the distance between the object and the moving machinery is based on time delay in correlating the radio frequency pulses with the return signals.
