Abstract
Abstract A system for transferring information via light signals from at least one station to at least one other station when the stations are generally capable of movement, one with respect to the other. In general, each station is capable of receiving and transmitting light signals through a light-conductor of light transparent material. At least one conical indentation is formed in the light conductor for the purpose of intercepting a portion of the light signals transmitted from one of the stations and reflecting the intercepted light signals to one of the other stations.
