SYSTEMS, METHODS, AND APPARATUS FOR RFID TAG DETECTION
First Claim
1. A system for tracking at least one object that includes at least one radio frequency identification (RFID) tag, the system comprising:
- a structure, the structure having an interior and radio frequency reflective walls;
at least one RFID reader panel that transmits a radio signal into the interior and is operable to read the at least one RFID tag in the interior; and
an operator terminal that receives and stores information regarding a read RFID tag from the at least one RFID reader panel.

Abstract
A system for tracking objects that include radio frequency identification (RFID) tags associated therewith. The system including a structure substantially defining an enclosure, a reflective interior of the enclosure configured for the reflection of radio signals, at least one conveyor belt that transports the objects through the structure, at least one RFID reader panel inside the structure, wherein the at least one RFID reader panel transmits a radio signal into the interior of the structure such that the radio signal will reflect off of the interior of the structure to increase a probability that the RFID tags associated with the objects that enter the structure are read, and an operator terminal that receives and stores information regarding read RFID tags from the at least one reader panel.

22. A method for tracking at least one object that includes at least one radio frequency identification (RFID) tag, the method comprising:
-
transmitting radio signals from one or more RFID reader panels into an interior of a structure having radio frequency reflective walls; and receiving an indication that the one or more RFID reader panels has successfully read the at least one RFID tag. - View Dependent Claims (23, 24, 25, 26, 27, 28)

29. An apparatus having an interior and radio frequency reflective walls for reflecting a radio signal transmitted from a radio frequency identification (RFID) reader panel to increase a probability that an RFID tag on an object is read, the apparatus comprising:
-
a first opening that allows a transport of at least one object including at least one RFID tag into the interior; a recognition component that identifies when the at least one object is present inside of the interior; at least one RFID reader panel that transmits a radio signal into the interior and is operable to read at least one RFID tag in the interior; a second opening that allows the transport of the at least one object out of the interior; and at least one reflective curtain at each of the first opening and the second opening, wherein the at least one reflective curtain limits the propagation of the radio signal transmitted from the at least one RFID reader panel; wherein the at least one REID panel comprises an antenna with a circulator to allow the antenna to both transmit the radio signal into the interior and to receive a response radio signal from the at least one RFID tag; and wherein the radio frequency reflective walls are made of aluminum.

30. A method for tracking an object that includes a radio frequency identification (RFID) tag through a structure with radio frequency reflective walls by reflecting a radio signal transmitted from a RFID reader panel to increase a probability that the RFID tag on the object inside the structure is read, the method comprising:
-
receiving an indication that at least one object including at least one RFID tag has entered the structure; transmitting radio signals from one or more RFID reader panels into an interior of the structure having radio frequency reflective walls; covering a first opening and a second opening of the structure with one or more reflective curtains once the at least one object has entered the structure wherein the one or more reflective curtains limit propagation of the radio signals transmitted from the one or more RFID reader panels; and receiving an indication that the one or more RFID reader panels has successfully read the at least one RFID tag or receiving and indication that a successful read of the at least one RFID tag on the at least one object has not been made.
