Abstract:
A method utilizing data from a multiplicity of sensor sources for detecting the occurrence of one of a plurality of different possible events which may occur within an area of interest which includes:deploying a plurality of sensor sources to provide sensor detections for an area of interest; choosing from said plurality of deployed sensor sources a unique group of sensor sources for each of said plurality of events to provide a specific sensor detection sequence associated with each event; identifying allowable time intervals between each sensor detection from sensor sources in each sensor detection sequence which will occur for said sensor detection sequence to indicate the occurrence of the event associated therewith; operating upon the receipt of a sensor detection from a first sensor source to identify all sensor detection sequences which include said first sensor source; operating upon receipt of one or more subsequent sensor detections from one or more additional sensor sources to compare the actual time interval between a sensor detections with the allowable time intervals between sensor detections in each identified sensor sequence containing said first sensor source; and when all of said actual time intervals fall within said allowable time intervals for one of said identified sensor sequences, identifying the event indicated by said one identified sensor sequence.
