Mobile telephone network-based system for detection and location of hazardous agents
First Claim
1. A cellular telephone network-based system for detecting hazardous agents, said cellular telephone network capable of locating cellular telephones in said network, said system comprisinga plurality of cellular telephones in public circulation, each cellular telephone having at least one detector for detecting at least one hazardous agent, said cellular telephone broadcasting over said cellular telephone network at least one alarm packet upon detecting said hazardous agent;
- andat least one computer interconnected with said plurality of telephones by said cellular telephone network for processing said alarm packet and setting an alarm condition for said hazardous agent in a vicinity of said cellular telephone configured to calculate based upon alarm packets from other telephones with detectors for said hazardous agent in said vicinity, said calculations including determination of a level of contamination of said hazardous agent in said vicinity and integration of said level of contamination of said hazardous agent over said vicinity, with bias due to variations in cellular telephone density over said vicinity removed, to determine whether a result of integration exceeds an alarm threshold.

Abstract
A system for detecting hazardous agents is based on cellular telephone networks. The cellular telephones in public circulation have at least one detector for detecting at least one hazardous agent and broadcast alarm packets upon detecting the hazardous agent. A computer or computer network interconnected with telephones by the cellular telephone network processes the alarm packets and sets an alarm condition for the hazardous agent in a vicinity of the cellular telephone by calculations based upon alarm packets from other telephones with detectors for the hazardous agent in the vicinity. A map of the contaminated area is also created.

11. In a system based on a cellular telephone network having a plurality of cellular telephones in public circulation, each cellular telephone capable of detecting one or more hazardous agents and being located by said cellular telephone network, a method comprising
receiving an alarm packet from any of said cellular telephones in public circulation responsive to detection of a hazardous agent, parsing said alarm packets to remove identifying data of said hazardous agent and a cellular telephone base station in communication with said telephone; -
determining a level of contamination of said hazardous agent in said vicinity from alarm packets from other telephones in said vicinity based on said identifying data; mathematically integrating said level of contamination over said vicinity, including eliminating bias due to variations in cellular telephone density over said vicinity; and determining whether a resulting integration value exceeds a threshold to determine whether an alarm condition for said hazardous agent in said vicinity exists. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
