Systems and methods for displaying location information for RFID tags
First Claim
1. A system comprising:
- a radio frequency identifier (RFID) reader comprising at least one antenna;
an imager configured to acquire images in a scanning area having an RFID tag;
a controller configured to operate the at least one antenna to transmit interrogation signals while the RFID reader is moved to scan portions of the scanning area and, concurrently at each of a plurality of points during such movement, acquire;
(1) location information indicating the portion within the scanning area being scanned, (2) a response, including phase, from any RFID tags within the portion of the scanning area being scanned, and (3) an image in the scanning area corresponding to the portion within the scanning area being scanned;
a processor configured to determine a location of the RFID tag within the scanning area based on the phase of the RFID tag response and the acquired location information at each position of the RFID reader during scanning; and
a display configured to display an image being only a portion of the scanning area corresponding to the location of the RFID tag within the scanning area.

Abstract
A system, method and computer readable medium are provided. One system includes a transmit antenna, at least one receive antenna, and an imager configured to acquire one or more images in a scanning area having one or more radio frequency identifier (RFID) tags including an RFID tag of interest. The system further includes a controller configured to operate the transmit antenna and the at least one receive antenna to acquire location information from the RFID tags, wherein the controller is further configured to operate the imager to acquire the images while the location information is acquired. The system includes a processor configured to correlate the acquired location information and the one or more images to determine an image corresponding to a location of the RFID tag of interest. The system additionally includes a display configured to display the image corresponding to the location of the RFID tag of interest.

9. A method for determining a location of a radio frequency identifier (RFID) tag, the method comprising:
-
scanning a scanning area for the RFID tag by sequentially scanning only portions of the scanning area; acquiring, in only portions of the scanning area being scanned, selective location information for the RFID tag from a RFID apparatus, the location information comprising phase of a response from the RFID tag; acquiring an image in the scanning area at each point when the location information is acquired during the scanning; determining, by a processor, a location of the RFID tag within the scanning area based on the phase of the RFID tag and the acquired location information at respective positions during scanning; displaying an image being only the location within the scanning area corresponding to the location of the RFID tag within the scanning area. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A non-transitory computer-readable storage medium comprising executable instructions capable of configuring one or more processors for:
-
receiving a user input to search for an RFID tag; transmitting interrogation signals in a scanning area while the RFID reader is moved to scan different areas within the scanning area; concurrently at each of a plurality of points during the movement of the RFID reader, acquiring;
(1) location information indicating a location within the scanning area being scanned, (2) a response from the RFID tag including a phase of the response, and (3) an image in the scanning area corresponding to the location within the scanning area being scanned;determining a location of the RFID tag within the scanning area based on the phase of the RFID tag response and the acquired location information at each position of the RFID reader during scanning; and displaying an image being only a portion of the scanning area corresponding to the location of the RFID tag within the scanning area. - View Dependent Claims (17, 18, 19, 20)
