Abstract
Systems, devices and methods, etc., that overcome one or more problems associated with high-speed monitoring of large numbers/volumes of postal articles of postal articles for dangerous materials and contaminants. Such monitoring can be more economic, practical, efficient and/or effective. The monitoring systems, methods, etc., herein provide positive pressure clean air passing through an interrogation zone in interrogation zone housing, through which suspect postal articles are pass to provide sampled air, which in turn is analyzed optically to detect dangerous materials such as illicit biologicals or chemicals and to identify the source envelope (or other postal article) to within a few envelopes.
Claims22
A high-speed mail sorting machine having an interrogation zone to assay for potentially dangerous postal articles, wherein the high-speed mail sorting machine comprises a high-speed postal article transfer system that rapidly transmits the postal articles through a postal article interrogation zone located within an interrogation zone housing, and wherein the interrogation zone housing comprises an input clean air end that receives purified air from an outside source and transmits the input clean air through a sampling zone contained within the interrogation zone housing to provide sampled air that is in turn transmitted to an optical analysis section that identifies within less than about 5 seconds potentially dangerous particles from the postal articles via optical scanning.
