ABSTRACT:
The present invention features a method and circuit for ensuring substantially continuous, on-line communications for a vehicle that is directed to travel along one of a plurality of closed loop guide paths. The system includes a signal generator, and a first buffer operatively connected to the signal generator and to a first guide member defining one of the plurality of closed loop guide paths. The generator and first buffer provide a first reference signal at a predetermined frequency. A second buffer is operatively connected to the signal generator and to a second guide member defining a second guide path. The second buffer provides a second signal at the predetermined frequency. Connected to the second buffer is a mechanism for shifting or time delaying the second signal relative to the first reference signal, as a periodic function of time. In this way, destructive coupling of signals provided in each of the guide members in their respective guide paths is substantially eliminated and constructive coupling of signals provides enhanced effective signal amplitude to the vehicle.
