Abstract

The present specification discloses a system for controlling a movement of at least one person into a controlled location. The system includes an X-ray screening system having an entrance area defined by walls and a gate, and an exit area defined by walls and a gate. The gates are automatically controlled based upon the output of the X-ray screening system. Additional gates, defining an additional holding area, are used for subsequent analysis and inspection.

Claims

1. An X-ray screening system positioned to control a flow of people to a secured area from an unsecured area comprising at least:

a scanner;

a scanning enclosure defined by a plurality of walls, a first gate, a second gate, and a third gate, the scanning enclosure comprising a scanning area for scanning an individual, wherein the plurality of walls comprises a first wall positioned in the unsecured area and having a proximal end and a distal end connected to the scanner, a second wall positioned in the secured area and having a proximal end connected to a first side of the scanner and a distal end, and a third wall positioned in the secured area and having a proximal end connected to a second side of the scanner opposing the first side and a distal end;

the first gate coupled with the proximal end of the first wall configured to open to allow the individual to enter into the scanning area;

the second gate coupled with the distal end of the second wall configured to allow the individual to exit the X-ray screening system if a clear signal is generated by the screening system after completing a scan, the second gate remaining closed if the first gate is open and the first gate remaining closed if the second gate is open; and

the third gate coupled with the distal end of the third wall configured to allow the individual to exit to a holding enclosure for inspection if a no-clear signal is generated by the system after completion of the scan, wherein the holding enclosure is defined by at least two walls and two gates, wherein the clear and no-clear signals are generated based on outcomes of the scan, wherein the second gate remains closed if a no-clear signal is generated, and wherein if the first gate is open, only one of the second and the third gates is open concurrently.

2. The screening system as claimed in claim 1 wherein the scanning enclosure further comprises a hold area for holding the individual during analysis of images captured during the scan, wherein the second gate allows the individual to exit the hold area upon completion of the analysis if the analysis does not result in a threat detection.

3. The screening system as claimed in claim 2 wherein one or more computer implemented processes are used to analyse the scan images, while the individual is in the hold area.

4. The screening system as claimed in claim 2 further comprising a fourth gate coupled with one of the plurality of walls configured to allow the individual to exit from the holding enclosure to an inspection area for manual inspection, if the analysis results in a threat detection.

5. The screening system as claimed in claim 2 further comprising a fifth gate coupled with one of the plurality of walls configured to allow the individual to exit the screening system if the analysis of the scan images does not result in a threat alarm.

6. The screening system as claimed in claim 1 wherein a signal is transmitted to open the second gate and close the third gate if a clear signal is generated by the screening system after completing the scan.

7. The screening system as claimed in claim 1 wherein a signal is transmitted to open the third gate and close the second gate if a no-clear signal is generated by the system after completing the scan.

8. The screening system as claimed in claim 1 wherein at least one of the first, second and third gates comprise a left panel and a right panel opening and closing in coordination, each of the panels being hinged to walls defining the scanning enclosure.

9. The screening system as claimed in claim 1 wherein the first gate opens automatically based upon a signal received from a sensor sensing an individual being within a pre-defined distance of the first gate and if the scanning enclosure does not contain one or more individuals.

10. The screening system as claimed in claim 1 wherein at least one of the first, second and third gates comprises a rotating door or a revolving door.
