  • Threat detection system having multi-hop arrangement of wireless detectors and wireless sensors and with at least one sensor having close-by low-cost low-power wireless sub-sensors for blanketing a venue
    Patent number: 9390608
    Abstract: A data sensing and threat detecting network comprising a plurality of wireless sensor devices for communication with wireless detector units in a multi-hop arrangement to allow transmission of data there between in optimized paths. The network further has a plurality of low power sub-sensor devices for transmission of data to respective sensor devices in close proximity thereto due to their low power, but their low cost allows them to be used in large numbers to blanket substantially all of the physical space in a venue. The sensor and sub-sensor devices may include portable sensor devices and condition sensing devices.

  • Threat detection system and method
    Patent number: 8994556
    Abstract: A data multi-hop sensing and threat detecting network, including modular sensor devices, smart plug and portable sensor devices, and low power sub-sensor devices. A determination is made to alert when a sensed value is either (1) greater than a predetermined upper threshold value or the running average baseline value (whichever is greater) plus the upper fluctuation buffer value, or (2) less than a predetermined lower threshold value or the 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.
