Abstract
The present invention is directed to an interrogator, method of discerning metal and radio frequency identification (RFID) objects, and an interrogation system employing the same. In one embodiment, the interrogator includes a metal sensing subsystem configured to provide a first signal having a signature representing a presence of a metal object, and a RFID sensing subsystem configured to provide a second signal having a signature representing a presence of a RFID object. The interrogator also includes a control and processing subsystem configured to discern a presence of at least one of the metal and RFID objects from one of the first and second signals.
Claims50
An interrogator, comprising:
- a metal sensing subsystem configured to provide a first signal having a metal signature representing a presence of a metal object;
- a radio frequency identification (RFID) sensing subsystem configured to provide a second signal having a RFID signature representing a presence of a RFID object;
- and
- a control and processing subsystem configured to discern a presence of at least one of said metal and RFID objects from one of said first and second signals.
A method of discerning a presence of at least one of metal and radio frequency identification (RFID) objects, comprising:
- providing a first signal having a metal signature representing a presence of a metal object;
- further providing a second signal having a RFID signature representing a presence of a RFID object;
- and
- discerning a presence of at least one of said metal and RFID objects from one of said first and second signals.
An interrogator, comprising:
- a sensing subsystem configured to provide a signal having at least one of a metal signature representing a presence of a metal object and a radio frequency identification (RFID) signature representing a presence of a RFID object;
- and
- a control and processing subsystem employing an adaptive integrating filter and configured to coordinate a processing of said signal in conjunction with one of an observable and data to discern a presence of at least one of said metal and RFID objects.
A method of discerning a presence of at least one of metal and radio frequency identification (RFID) objects, comprising:
- providing a signal having at least one of a metal signature representing a presence of a metal object and a radio frequency identification (RFID) signature representing a presence of a RFID object;
- coordinating a processing of said signal in conjunction with one of an observable and data in conjunction with an adaptive integrating filter;
- and
- discerning a presence of at least one of said metal and RFID objects.
An interrogator, comprising:
- a sensing subsystem configured to provide a plurality of signals having at least one of a metal signature representing a presence of a metal object and a radio frequency identification (RFID) signature representing a presence of a RFID object;
- and
- a control and processing subsystem configured to coordinate a processing of said plurality of signals to discern a presence of at least one of said metal and RFID objects.
A method of discerning a presence of at least one of metal and radio frequency identification (RFID) objects, comprising:
- providing a plurality of signals having at least one of a metal signature representing a presence of a metal object and a radio frequency identification (RFID) signature representing a presence of a RFID object;
- coordinating a processing of said plurality of signals;
- and
- discerning a presence of at least one of said metal and RFID objects.
An interrogation system, comprising:
- a computer system;
- a transceiver that transmits and receives signals for said computer system;
- and
- an interrogator, including:
- a metal sensing subsystem that provides a first signal having a metal signature representing a presence of a metal object,
- a radio frequency identification (RFID) sensing subsystem that provides a second signal having a RFID signature representing a presence of a RFID object,
- a control and processing subsystem that discerns a presence of at least one of said metal and RFID objects from one of said first and second signals, and
- a communications subsystem that communicates with said transceiver.
