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; and
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.

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.

10. 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 with a subject; utilizing the pressure sensor to determine a pressure applied to the contact pad by the subject during a sample collection process; and analyzing the sample collection sheet with the sample processing system to determine whether the trace residue sample contains a threat residue, while the spatial recognition system focuses the sample processing system on particular portions of the sample collection sheet contacted by the subject. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
