Patent ID: 8085132

Claim:
A method for resolving RFID-based object traffic transactions to a single object in the presence of a plurality of objects comprising the steps of: a) monitoring RFID object traffic transactions to a single object amongst a plurality of objects wherein said traffic transactions are between at least one RFID reader and a plurality of detected RFID tags detected by said at least one RFID reader, wherein said at least one RFID reader is chosen from the group consisting of: a plurality of stationary RFID readers, at least one mobile RFID reader, b) calculating a cumulative and weighted data set for each detected RFID tag of said RFID tags, c) comparing said data set for said each detected RFID tag with said data set for other of said detected RFID tags and identifying one RFID tag of said detected RFID tags having a greatest cumulative weight calculated for its corresponding said data set so as to resolve multiple detections and identifications of said detected RFID tags in said object traffic transactions to said single object, d) calculating a plurality of overlapping proximity zones for said single object and combining said proximity zones so as to determine a maximum overlapped area having the greatest number of overlaps of said plurality of overlapping proximity zones, wherein said maximum overlapped area coincides with an area of increased probability of location of said single object, wherein said data set includes the following data for said each detected RFID tag: radio frequency signal strength, an incremental count of the number of said RFID tag detections and identifications, and the corresponding clock time for each count in said incremental count, and wherein said data is, in order of most important to least important, weighted by said signal strength, said incremental count, and said corresponding clock time.
