US 2006/0187018 A1 · CHEMICAL, BIOLOGICAL, RADIOLOGICAL, AND NUCLEAR WEAPON DETECTION SYSTEM COMPRISING ARRAY OF SPATIALLY-DISPARATE SENSORS

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. The illustrative embodiment also incorporates a mechanism to reduce the probability that a false alarm will be issued. In particular, the illustrative embodiment requires that at least 2 stations report an alarm for the same hazardous material within an interval of time. This prevents a false alarm from one hazardous material detection station from issuing a false system-wide alarm. This is based on the assumption that a real attack is more likely to be detected by stations that are near each other than by stations that have no proximity.

Dependent claims

A system comprising:

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 of said neighboring hazardous material detection stations issues said first alarm;
wherein N, M, and K are positive integers and 1<N≦M≦K.
