Abstract
A closed coupled identification system for verifying the identity of an animal, object or other thing, has a probe including a circuit adapted to be connected to a source of alternating current and a separate, preferably miniature, circuit adapted to be implanted within or attached to the animal, object or thing. The probe circuit is held adjacent the implanted circuit for mutually inductively coupling the circuits so that a load applied to the implanted circuit has an effect on the current in the probe circuit. A programmable load is included in the implanted circuit, along with means for sequentially connecting and disconnecting the load to and from the implanted circuit in response to alternating current cycles in the probe circuit, according to a predetermined code program. A signal is derived from the probe circuit having a waveform corresponding to the coded program in the implant circuit. Further means are employed to decode the waveform and to display a number or other representation corresponding to the code program and indicating the identity of the implanted circuit, and, hence of the animal, object or thing.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
