Method and apparatus for extracting information from an array of hazardous material sensors
First Claim
1. 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.

Abstract
Information may be extracted from an array of relatively low sensitivity hazardous material sensors deployed, for example within a population center, by collecting identification information, such as video data, RFID data, proximity data, and IR data along with the hazardous material sensor reading. The identification information may then be used to identify objects in the vicinity of the hazardous material sensor at the time the reading was taken. By using identification data to identify an object, and then correlating sensor data readings for that object with other sensor data readings for the same object, as identified using previously collected identification information, a statistically more significant reading may be obtained for that particular object than would be obtainable by any one particular hazardous material sensor. Optionally the proximity of the object to the sensors may be used to weight the readings from the sensors.
