Title: Innovations by Stewart Berry in Explosive and Narcotic Detection

Introduction

Stewart Berry is an accomplished inventor based in Ottawa, Canada, known for his significant contributions to the field of detection technology. With a total of three patents to his name, Berry has developed innovative solutions aimed at enhancing safety and security through the detection of contraband substances.

Latest Patents

Berry's latest patents include groundbreaking technologies for the chemiluminescent detection of explosives, narcotics, and other chemical substances. One of his notable inventions is a compact scanning apparatus that utilizes an infrared laser to emit light. This light illuminates an interrogation area on the surface of an object being scanned, causing selective desorption of molecules of contraband substances without damaging the surface. The apparatus collects these desorbed molecules, thermally decomposes them to form nitric oxide (NO), and transfers them to a reaction cell containing a luminol solution. The reaction produces light through chemiluminescence, which is detected to indicate the presence of contraband, activating an alarm system. This technology allows for rapid and accurate detection, minimizing false alarms and enhancing detection efficacy.

Another patent focuses on multi-modal detection, incorporating a supplemental detector such as a gas chromatography-ion mobility spectrometry (GC/IMS) system. This system is activated upon detecting chemiluminescent light, providing confirmation of contraband presence and enabling thorough scrutiny of suspicious items. The combination of effective detection and high throughput makes Berry's inventions invaluable in security applications.
