MULTI-MODAL TRANSPONDER AND METHOD AND APPARATUS TO DETECT SAME
First Claim
1. A system for detecting and identifying an object, the system comprising:
- an identification transponder including at least a first inductive winding and an integrated circuit that stores an identifier, the first inductive winding electrically coupled to the integrated circuit and operable to transmit an identification signal from the identification transponder in response to receipt of an interrogation signal in a first frequency range, the identification signal encoding an identifier stored by the integrated circuit; and
a presence/absence transponder including a resonant inductive/capacitive tank circuit having at least a second inductive winding and a capacitor, the second inductive winding electrically coupled to the capacitor and operable to transmit a presence/absence signal from the presence/absence transponder in response to an interrogation signal in a second frequency range, the presence/absence response signal omitting any unique identifying information, the presence/absence transponder physically coupled to the identification transponder to form an integral detection and identification transponder that can selectively be attached to the object.

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.

19. A system for detecting and identifying an object, the system comprising:
-
an identification transponding means for transmitting an identification signal in response to a first interrogation signal, the identification signal including identification information that uniquely identifies the identification transponding means; and a presence/absence transponding means for transmitting a presence/absence signal in response to a second interrogation signal, the presence/absence signal excluding identification information that uniquely identifies the presence/absence transponder, the second interrogation signal different from the first interrogation signal, wherein the identification transponding means and the presence/absence transponding means are physically coupled to one another to form an integral detection and identification transponder configured to be selectively attached to the object. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A method of detecting and identifying a medical object coupled to a multi-mode integral detection and identification transponder having a resonant circuit transponder assembly and a radio frequency identification (RFID) transponder assembly, the method comprising:
-
scanning a selected area by transmitting a first interrogation signal in a first frequency range at a first time; providing an indication of presence of the medical object when a presence/absence signal is transmitted from the resonant circuit transponder assembly in response to the first interrogation signal; transmitting a second interrogation signal in a second frequency range at a second time; receiving an identification signal, carrying identification information encoded in the RFID transponder assembly and associated with information corresponding to at least one attribute of the medical object, from the RFID transponder assembly in response to the second interrogation signal; and decoding the identification information and providing an indication of the identification information. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37)
