Title: Innovations by Patrick M Shea in Explosive Detection Systems
Introduction
Patrick M Shea is a notable inventor based in Sunnyvale, CA, with a focus on advanced detection systems. He holds 5 patents that contribute significantly to the field of explosive detection. His work emphasizes the integration of artificial neural systems to enhance detection accuracy and efficiency.
Latest Patents
One of Shea's latest patents is a multi-sensor explosive detection system utilizing an artificial neural network. This innovative nuclear detection system is designed to efficiently identify explosives in checked airline baggage and other parcels. It operates with a high probability of detection (PD) and a low probability of false alarms (PFA). The system analyzes the presence of nitrogen and other elements, determining their rough density distribution through nuclear-based analysis. It includes a neutron source, an array of gamma ray detectors, and means for capturing and counting elemental-specific gamma rays. This technology provides a rough measure of density distribution and incorporates an X-radiography system for generating high-resolution images.
Another significant patent by Shea is an explosive detection system that identifies explosives contained in an object under observation. This system features a cavity structure for receiving the object and a radiation source that produces thermal neutrons directed at the object. Gamma rays are generated to indicate the presence of explosives, particularly focusing on nitrogen concentration. Inorganic scintillators are strategically placed within the cavity structure to detect gamma rays and produce output signals representative of the elements present. The object is moved through the cavity to build a three-dimensional profile of explosive concentration.
