US Patent:

7032467, Apr 25, 2006

Filed:

Oct 28, 2002

Appl. No.:

10/281680

Inventors:

Sung Hoon Yoon - Leonia NJ, US

International Classification:

G01N 1/38

US Classification:

7386381, 73 232, 73 3103, 73 3104, 73 3107

Abstract:

This apparatus and method allows collection concentrated sample of content in shipping packages without unsealing the package by forcing airflow via existing hidden gaps or, if necessary, creating one by a small incision. The air is injected into the hidden gaps by either probe or socket device to disturb and agitate contents inside the package, causing the contents to loosen and blend particulates on the surface into the air stream. Airborne particles are channeled into detection device, where the particulates are concentrated. Display and warning apparatus receives and records the analysis results from detection device. If the analysis finds that predetermined selection and sensitivity criteria for target hazard or contraband is met, then the warning apparatus initiates appropriate alert protocols.
