Interactive security screening system
First Claim
1. A method of obtaining and analyzing a sample from a subject through interaction with an interactive security screening system comprising:
- pressing an object associated with the subject upon a sample collection sheet positioned over a contact pad, said object exerting an amount of pressure upon the contact pad;
sensing the amount of pressure applied to the contact pad through portions of the sample collection sheet;
analyzing whether the amount of pressure sensed is sufficient to indicate that a proper sample has been obtained on the portions of the sample collection sheet; and
analyzing the portions of the sample collection sheet with a sample processing system that scans the proper sample for threat residue.

Abstract
An interactive security screening system includes a main housing, a contact or palm pad provided on the main housing and a sample sheet positioned upon the contact pad. A sensor is operatively connected to the contact pad to measure pressure applied to the contact pad during a sample collection process. A feedback system, operatively connected to the contact pad and the sensor, provides the subject or screener with at least one of a visual signal and an audio signal to indicate whether requisite pressure was applied to the contact pad. A sample processing system analyzes the sample collection sheet through series, parallel or image processing to determine whether the trace residue sample contains a threat residue. The screening system also employs a spatial recognition system that focuses the sample processing system on particular portions of the sample collection sheet to increase overall system accuracy.

11. A method of obtaining and analyzing a sample from a subject through interaction with an interactive security screening system including a main housing, a contact pad provided on the main housing, a sample collection sheet positioned upon the contact pad, a pressure sensor operatively linked to the contact pad, a sample processing system and a spatial recognition system operatively connected to the sample processing system, said method comprising:
-
receiving a trace residue sample upon contact of the sample collection sheet with a subject; utilizing the pressure sensor to determine a pressure applied to the contact pad by the subject during a sample collection process; utilizing the spatial recognition system to focus the sample processing system on particular portions of the sample collection sheet including the trace residue sample; and analyzing only the particular portions of the sample collection sheet with the sample processing system to determine whether the trace residue sample contains a threat residue. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A method of obtaining and analyzing a sample from a subject through interaction with an interactive security screening system comprising:
-
pressing an object associated with the subject upon a sample collection sheet positioned over a contact pad, said object exerting an amount of pressure upon the contact pad; sensing the amount of pressure applied to the contact pad to assure that a proper sample has been obtained; analyzing the sample collection sheet with a sample processing system that scans the proper sample for threat residue, wherein the sample processing system is only directed to particular portions of the sample sheet for scanning; and performing at least two cycles of chemical application followed by illumination in determining whether the sample collection sheet includes a threat residue.
