Abstract

An integral detection and identification system for detecting and identifying an object includes an identification transponder and a presence/absence transponder. The identification transponder includes a first inductive winding wound about a core and electrically coupled to an integrated circuit to transmit an identification signal in response to receipt of an interrogation signal in a first frequency range. The identification signal encodes an identifier stored by the integrated circuit. The presence/absence transponder includes a resonant inductive/capacitive tank circuit having at least a second inductive winding wound about a core and electrically coupled to a capacitor to transmit a presence/absence signal in response to an interrogation signal in a second frequency range. The presence/absence response signal lacks unique identifying information and is physically coupled to the identification transponder to form an integral detection and identification transponder that can selectively be attached to the object.
