Abstract:
An Identification system comprising:Counterparts with electrical circuits in them; some of said Counterparts are attached to things; a Counterpart, which has a known identity, is within range of electromagnetic emissions from some of the Counterparts attached to said things and it emits an electromagnetic code which identifies the category the Counterpart belongs in, and some of said other Counterparts start to pulsate in unison because the emitted code matches their category code thereby activating their inductive pulse circuits; and following the category match the Counterpart with the known identity emits a momentary irregularity in its pulsing emission; after a varied number of pulses the said other Counterparts emit irregularities in their inductively pulsing circuits; said Counterpart of known identity is designed to receive emissions at one particular pulse number following its emitted irregularity and no other; and if said other Counterpart's emitted irregularity occurs at that one pulse number identity is established by the reception of emissions to said Counterpart of known identity after which the Counterparts have means to indicate emissions have been sent and received, whereby Identification has been validated.
