Abstract

An identification system (10) of the present invention is used at airport terminals, bus stations, government buildings, and the like. The identification system (10) includes a controller (26), a pair of spaced stations or checkpoints (12, 14) for generating a first reference and a second reference each containing scanning image and weight of the person (P) passing through the first (12) and second (14) spaced stations. The controller (26) includes a comparative software that determines a correlation between the first and second references to identify at least one discrepancy therebetween. As the discrepancy is identified, a distress signal is send by the controller (26) to the second station (14) to alert about the discrepancy being identified. The invention includes a method of identifying the person (P).

4. The identification system as set forth in claim 3, wherein said comparator compares said first plurality of the pixels with said second plurality of the pixels and said first value of the weight with said second value of the weight to determine at least one correlation.

5. The identification system as set forth in claim 2, wherein said first station includes a first camera for scanning the person and a first weight measuring device for measuring weight of the person, said first camera each operatively communicating with said controller.

6. The identification system as set forth in claim 3, wherein said second station includes a second camera for scanning the person and a second weight measuring device for measuring weight of the person, said second camera and said second weight measuring device each operatively communicating with said controller.

7. The identification system as set forth in claim 6, including an alarm device operated by said controller for generating said signal as said discrepancies between said first plurality of the pixels and said second plurality of the pixels or said first value of the weight and said second value of the weight are identified.

8. The identification system as set forth in claim 5, wherein at least one of said first camera and said second camera is a charge-coupled camera.

9. The identification system as set forth in claim 5, wherein at least one of said first camera and said second camera is a high dynamic range camera.

10. The identification system as set forth in claim 5, wherein at least one of said first camera and said second camera is an active pixel camera.

11. The identification system as set forth in claim 5, wherein at least one of said first camera and said second camera is a metal oxide semiconductor camera.

12. An identification system for identifying a person entering a secured area, comprising:

a controller,

a first identification station having a reference imager generating a reference image and a reference weight measuring device generating reference weight of the person entering the secured area each being electronically communicating with said controller for signaling said controller said reference image and said reference weight thereby generating a reference data point associated with said first identification station;

a second identification station spaced from said first identification station having a secondary reference imager generating a secondary image and a secondary weight measuring device generating a secondary weight of said person passing through said secured area each being electronically communicating with said controller for signaling said controller said secondary image and said secondary weight thereby generating a secondary data point associated with said second identification station, and

said controller indicating an alarm situation if said reference data point is different than said secondary data point.

13. The identification system as set forth in claim 12, wherein said controller indicates an alarm situation if said reference image is different from said secondary image or if said reference weight is different than said secondary weight.

14. The identification system as set forth in claim 12, wherein said first identification station includes a first luggage scale for weighing carry on luggage at said first identification station and said second identification includes a second luggage scale for weighing carry on luggage at said second identification station.

15. The identification system as set forth in claim 14, wherein said first and second luggage scales electronically communicate with said controller for transmitting to said controller a reference luggage weight and a secondary luggage weight enabling said controller compare said reference luggage weight to said secondary luggage weight and indicate an alarm situation if said first luggage weight is different than said second luggage weight.
