Interactive security screening system
First Claim
1. A security screening system comprising:
- a main housing;
a contact pad provided on the main housing;
a sample collection sheet positioned upon the contact pad, said sample sheet receiving a trace residue sample upon contact with a subject;
a pressure sensor operatively linked to the contact pad, said sensor configured to determine a pressure applied to the contact pad during a sample collection process;
a sample processing system provided in the main housing, said sample processing system analyzing the sample collection sheet to determine whether the trace residue sample contains a threat residue; and
a spatial recognition system operatively connected to the sample processing system, said spatial recognition system configured to focus the sample processing system on particular portions of the sample collection sheet.

Abstract
An interactive security screening system includes a main housing, a contact 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.
