Radio frequency controlled interrogator-responder system with passive code generator

摘要

An electronic system for automatically identifying objects employing microminiature electronic circuitry supported by each object and containing three operable subsystems, (a) a means for converting shortwave energy from a local energy field to electrical energy, (b) a means for generating coded electrical signals and (c) a means for shortwave transmitting such signals as codes to a local receiver. The system also includes a shortwave receiving means and an electronic computer operable to process and analyze the coded signals received by the receiver from the electronic circuitry energized when in the energy field. The computer generates control signals which are recorded and are utilized in tracking the objects.
