RFID system with a mobile RFID reader
First Claim
1. An RFID system comprising:
- a pair of guide tracks located on opposite boundaries of at least one zone, wherein the at least one zone is at least a portion of a predefined area;
a channel movably attached to the guide tracks, wherein the channel is configured to move along the guide tracks through the at least one zone; and
a mobile RFID reader movably attached to the channel, wherein the mobile RFID reader is configured to move along the channel and pause at a plurality of read points within the at least one zone to scan for RFID tags located within the predefined area, wherein the plurality of read points are determined by an arrangement of a plurality of hexagonal areas which are grouped together to create a combined area, wherein the combined area is aligned with the predefined area to define locations of the plurality of hexagonal areas, and wherein substantially central locations each hexagonal area represent the plurality of read points.

Abstract
An RFID system includes a pair of guide tracks located on opposite boundaries of at least one zone. A channel is movably attached to the guide tracks and is configured to move along the guide tracks through the at least one zone. A mobile RFID reader is movably attached to the channel and the mobile RFID reader is paused at a plurality of read points to scan for RFID tags located. The read points are determined by an arrangement of a plurality of hexagonal areas which are grouped together to create a combined area, where the combined area is aligned with the predefined area to define locations of the plurality of hexagonal areas, and where substantially central locations of each hexagonal area represent the plurality of read points.

10. A method of scanning for RFID tags comprising:
-
arranging a plurality of hexagonal areas together to form a combined area, wherein each hexagonal area represents an area of coverage of a mobile RFID reader; aligning the combined area with a predefined area to define locations of the plurality of hexagonal areas in the predefined area; moving a channel along a pair of guide tracks, wherein the guide tracks are located on opposite boundaries of at least one zone, wherein the at least one zone is at least a portion of the predefined area; moving the mobile RFID reader along the channel through at least a portion of the at least one zone; pausing the mobile RFID reader at a read point within the at least one zone, wherein the read point comprises a substantially central location of a hexagonal area; and scanning for RFID tags with the mobile RFID reader while the mobile RFID reader is paused at the read point. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A non-transitory computer readable storage medium on which is embedded one or more computer programs, said one or more computer programs implementing a method for localizing a tag, said one or more computer programs comprising a set of instructions for:
-
arranging a plurality of hexagonal areas together to form a combined area, wherein each hexagonal area represents an area of coverage of a mobile RFID reader; aligning the combined area with a predefined area to define locations of the plurality of hexagonal areas in the predefined area; moving a channel along guide tracks, wherein the guide tracks are located on opposite boundaries of at least one zone, wherein the at least one zone is at least a portion of the predefined area in the combined area; moving the mobile RFID reader along the channel through at least a portion of the at least one zone; pausing the mobile RFID reader at a read point within the at least one zone, wherein the read point comprises a substantially central location of a hexagonal area; and scanning for RFID tags with the mobile RFID reader while the mobile RFID reader is paused at the read point. - View Dependent Claims (20)
