Estimating the term…
An object tracking and management system and method using radio-frequency identification (“RFID”) tags is disclosed. Objects to be moved between locations are outfitted with RFID tags having information relating to the identities of the objects. The locations are also marked by RFID tags containing information on the locations. A transport vehicle for moving the objects is equipped with an RFID interrogator capable of detecting signals from the RFID tags. An onboard processor provides the operator of the vehicle with instructions on the movement of objects. The processor also determines the identities of the objects and locations from the detected signals and provides the operator with feedback as to the identity of an object being moved, the location of the vehicle and any error in carrying out the instructions. Numerous variations of the basic system and method using RFID tags are also described.
A system for tracking an object positionable at a plurality of locations, the system comprising:
A system for tracking an object positionable at a plurality of locations on a traffic-bearing surface, the system comprising:
A method of managing an object to be moved between locations in an environment wherein a first radio-frequency identification tag is affixed to the object and has stored therein and is capable of transmitting signals encoded with information indicative of the identity of the object, a second radio-frequency identification tag is affixed at a location and has stored therein and is capable of transmitting signals encoded with information indicative of the location of the second tag, and a transport vehicle is equipped with a radio-frequency identification tag interrogator, capable of receiving the signals from the tags and determining the information stored in the tags, the method comprising:
