Abstract

Abstract An automatic information transmission system for a mobile object, the system including a response unit arranged to be carried along with the mobile object, and an interrogation unit arranged to be disposed alongside the path of movement of the mobile object for movement of the response unit past the interrogation unit. The interrogation unit is arranged to emit a carrier signal at a first frequency and to receive a signal at a second frequency different from the first frequency. The response unit includes a memory for storing information relating to the mobile object, a signal generator connected to the memory for generating a signal at the second frequency and containing the stored information, a signal receiver for receiving the carrier signal at the first frequency emitted by the interrogation unit, an emitter connected to the signal generator for emitting the signal generated thereby, and an energy converter connected between the signal receiver and signal generator for deriving operating power for the generator from the carrier signal at the first frequency.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 275 words
An automatic information transmission system for a mobile object comprising a response unit arranged to be carried along with the mobile object, and an interrogation unit arranged to be disposed alongside the path of movement of the mobile object for movement of said response unit past said interrogation unit, said interrogation unit comprising: means for emitting a carrier signal at a first frequency; and means for receiving a signal at a second frequency different from the first frequency, and said response unit comprising: electric circuit components including memory means for storing information relating to the mobile object, and signal generator means connected to said memory means for generating a signal at the second frequency and continaing the stored information; signal receiving means for receiving the carrier signal at the first frequency emitted by said emitting means of said interrogation unit; emitting means connected to said signal generator means for emitting the signal generated thereby; a transmitting/receiving antenna consisting of a single induction coil and forming part of both said signal receiving means and said emitting means of said response unit, said signal receiving means of said response unit comprising a first resonant circuit tuned to the first frequency and including at least part of said coil, and said emitting means of said response unit comprising a second resonant circuit to the second frequency and including at least part of said coil; and energy conversion means connected between said signal receiving means of said response unit and said circuit components for deriving operating power for said circuit components from the carrier signal at the first frequency received by said signal receiving means of said response unit.
Claim 2
Dependent Claim 275 words
An automatic information transmission system for a mobile object comprising a response unit arranged to be carried along with the mobile object, and an interrogation unit arranged to be disposed alongside the path of movement of the mobile object for movement of said response unit past said interrogation unit, said interrogation unit comprising: means for emitting a carrier signal at a first frequency; and means for receiving a signal at a second frequency different from the first frequency, and said response unit comprising: electric circuit components including memory means for storing information relating to the mobile object, and signal generator means connected to said memory means for generating a signal at the second frequency and continaing the stored information; signal receiving means for receiving the carrier signal at the first frequency emitted by said emitting means of said interrogation unit; emitting means connected to said signal generator means for emitting the signal generated thereby; a transmitting/receiving antenna consisting of a single induction coil and forming part of both said signal receiving means and said emitting means of said response unit, said signal receiving means of said response unit comprising a first resonant circuit tuned to the first frequency and including at least part of said coil, and said emitting means of said response unit comprising a second resonant circuit to the second frequency and including at least part of said coil; and energy conversion means connected between said signal receiving means of said response unit and said circuit components for deriving operating power for said circuit components from the carrier signal at the first frequency received by said signal receiving means of said response unit.
