Title:
THREAT DETECTION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2013/186640
Kind Code:
A3
Abstract:
A data multi-hop sensing and threat detecting network comprising a plurality of sensor devices including modular sensor devices for communication with detector units, a smart plug sensor device, a portable sensor device which communicates with an associated detector device via a cellular or WiFi network, a plurality of low power sub-sensor devices including modular sub- sensor devices for communication with at least one of said sensor devices, wherein directly related data is sensed and adjusted for. In order to determine, based on a predetermined threshold value and a difference between the predetermined threshold value and a predetermined modified threshold value for a sensed condition, at what sensed value to alert, a running average baseline is kept of sensed values, and it is determined to alert when a sensed value is at a value which is either (1) greater than the upper threshold value or the running average baseline value (whichever is greater) plus the upper fluctuation buffer value, or (2) less than the lower threshold value or running average baseline value (whichever is less) less the lower fluctuation buffer value. The running average baseline is smoothed by applying large number numerology to the sensed values.
