Multi-Modal Active RFID Tag With Biometric Sensors, Systems and Methods of ITV Tracking
First Claim
1. A radio frequency identification and autonomous tracking system comprising:
- a) an active, multi-mode radio frequency identification tag having at least one of a uni-directional or bi-directional primary and secondary communication mode, said primary communication mode comprising a radio frequency transceiver and said secondary communication mode comprising an optical transceiver, an ultra-sound transceiver, and both an optical and an ultra-sound transceiver;
b) a reader communicatively coupled with and adapted with a radio frequency receiver to receive signals representative of information from the radio frequency identification tag via the radio frequency transmitter of the radio frequency identification tag;
c) an illuminator, positioned within the field of view of said tag, communicatively coupled with and adapted with an optical transmitter or an ultrasound transmitter to send triggering information signals to the radio frequency identification tag via the secondary mode optical or ultra-sound receiver of the radio frequency identification tag; and
d) said tag is configured for linking at least one of receipt of or absence of receipt of a secondary mode communication signal from said illuminator to transmit by said tag signals between said tag and said reader via said radio frequency primary communication mode, said signals representing information, data, sensor data, tag identification, identification of an object or person with which said tag is associated, illuminator identification, and combinations thereof.

Abstract
RFID tags, methods and systems for total asset management, in-transit visibility and bio-metric verification and authorization. The system comprises an active, multi-modal, bi-directional RFID tag having a primary communication mode RF transceiver and a secondary mode IR/US transceiver. The tag includes sensors, such as bio-metric, and memory containing user bio-metric data. A reader and illuminator(s), preferably IR and/or US, are communicatively coupled with the tag and adapted to provide command and control signals to the tag and receive data/information from it. The user'"'"'s bio-metric data is read by the sensor, compared to the data base and verification communicated to an access or point of sale device. The tag looks for illuminators and reports to the reader the IDs of those it sees. The detection history permits tracking and locating tagged objects or persons, such as theme park guests. If no illuminator signal is seen, the tag sends a special signal.

15. A method of communicating with a radio frequency identification tag in a radio frequency identification and tracking system comprising a plurality of tags, and at least one other, separate device having at least one illuminator functionality, the method comprising the steps of:
-
a) providing an active, multi-modal radio frequency tag having a primary, radio frequency, mode of communication and at least one secondary, optical or ultrasonic, mode of communication;
b) illuminating a field of view by a secondary, optical or ultrasonic, mode of communication signal from at least one illuminator of said radio frequency identification system;
c) linking, in said tag, the transmission by said tag of a selected signal, of at least one of said primary, radio frequency, and said secondary, optical or ultrasonic, mode of communication upon receipt, or not, by said tag of said secondary mode of communication signal from said illuminator;
c) transmitting a primary, radio frequency, or secondary, optical or ultrasonic, mode of communication signal to at least one reader, or illuminator within the field of view of said tag, of said system and d) receiving said selected signal transmitted from the radio frequency identification tag in response to the reader or illuminator signal to determine information local to said tag. - View Dependent Claims (16, 17, 18, 19, 20, 21)
