Abstract
An Apparatus and Method for reliably sorting RFID chips, in inlays, labels, tags or other units of manufacture, into rows and columns, and using that information to report their exact position on a moving web, in support of further manufacturing processes, in the presence of crosstalk, with speed and accuracy exceeding prior art.
Claims13
A method of determining a position of each member of a plurality of RFID tags in motion through a manufacturing process, comprising:
- a. providing a plurality of RFID readers, each coupled to one of a plurality of RFID antennas, sized to interact with one or more said RFID tags, performing a plurality of RFID tag read operations on said RFID tags in response to a plurality of trigger events from a sensor or an external control system,
- b. recording s plurality of RFID data from said RFID tag read operations in a computationally efficient manner,
- c. using a software algorithm to derive a pattern from said RFID data to determine said position of each said RFID tag relative to said antennas, including said position of bad RFID tags that may be present,
- d. reporting said position of each said RFID tag in said plurality for use in a further manufacturing process.
