Patent ID: 7467069

Claim:
A method of obtaining enhanced resolution from an array of low resolution hazardous material sensors, the method comprising the steps of: receiving identification information associated wit an object in a vicinity of a first low resolution hazardous material sensor; receiving a first low resolution hazardous material sensor reading from the first low resolution hazardous material sensor; receiving proximity information associated with the object, the proximity information being a value of a distance between the object and the hazardous material sensor; processing the identification information to determine an identity of the object; and correlating the first low resolution hazardous material sensor reading with other low resolution hazardous material sensor readings taken using other low resolution hazardous material sensors at different geographic locations for the same object based on the identity of the object, to obtain a statistically more significant collective sensor reading than may be obtained from one of the individual low resolution hazardous material sensor readings; wherein the proximity information is used to weight the hazardous material sensor reading during the step of correlating.
