US 7,257,493 B1 · Chemical, biological, radiological, and nuclear weapon detection system comprising array of spatially-disparate sensors and environmental acuity

Abstract

A chemical, biological, radiological, and nuclear weapons detection system is disclosed that comprises an array of spatially-disparate hazardous material sensors that all feed into a centralized system control center. This enables the embodiment to receive and coordinate in one place all of the hazardous material sensors spread over a wide area, and, therefore, enables an alarm to be quickly issued in the event of a real attack. To accurately reduce false alarms, the illustrative embodiment requires that at least N of M neighboring stations report an alarm for the same hazardous material within an interval of time, and that the values of at least one of N and M change and are based on at least one environmental factor.

Dependent claims

A system comprising:

a first environmental sensor for monitoring a first environmental factor;
K spatially-disparate hazardous material detection stations, wherein each of said K hazardous material detection stations issues a first alarm when the amount of a first hazardous material reaches a first threshold;
and
a first system-wide alarm that is triggered when N of M neighboring hazardous material detection stations issues said first alarm;
wherein N, M, and K are positive integers and 1<N≦M≦K;
and
wherein at least one of N and M change based on said first environmental factor.
