A wide-area wildfire suppression system uses a network of geographically distributed water sprayers, and includes at least one wind sensor and a fire-suppression controller communicatively coupled to the water sprayers and the at least one wind sensor. The at least one wind sensor detects wind direction and communicates wind-direction information to the fire-suppression controller, which uses the wind-direction information to activate at least one of the water sprayers upwind of an asset or area to be protected. Parameters of the water spray, such as flow rate, droplet size, spray pattern, spray direction, spray elevation, or aeration, can be adapted based on wind direction or wind speed.

A device for characterizing a fire comprises at least one stereovision system and at least one processing unit. The at least one stereo vision system comprises a first and a second image capture unit. The at least one processing unit is configured to determine at least one geometric characteristic of the fire. The processing unit is also configured to determine a radiative flux of this fire on the basis of a calibrated linear relationship established between a radiative flux of a reference fire as a function of at least one of the geometric characteristics of the fire and of at least one fire category in order to be able to determine zones exposed to a radiative flux that exceeds a reference threshold. The present disclosure also relates to a method for determining radiative fluxes that implements such a fire characterizing device.

Tools for fire monitoring are presented. One method includes an operation for accessing values of features for monitoring a fire in a region. The features include satellite images at a first resolution, vegetation information, and weather data. Further, each satellite image includes first cells associated with the geographical region and the first resolution defines a first size of each first cell. The method further includes generating a map of the geographical region comprising a plurality of second cells having a second size, which is smaller than the first size. Additionally, the method includes operations for estimating, using a machine-learning model, probability values for the second cells in the map based on the features, each probability value indicating if the second cell contains an active fire, and for updating the map based on the probability values for the second cells. The map is presented in a user interface.

An autonomous firefighting system is disclosed. The autonomous firefighting system may include a controller coupled to one or more unmanned aircraft, one or more unmanned vehicles, one or more valves of a water spraying system, or a combination thereof, and further coupled to one or more fire-associated risk surveillance assets (FARSAs). The controller utilizes the FARSA(s) to detect a fire-associated risk event, which may include an active or potential fire event, and subsequently creates and delivers instructions to the one or more unmanned aircraft, one or more unmanned vehicles, one or more valves of a water spraying system, or combination thereof for mitigating damage associated with the actual or potential fire-associated risk event.

A watchtower vehicle, including: a top plate engaged with a top of a vehicle; an extendable boom, with a first end thereof engaged with the top plate, wherein the extendable boom is allowed to be inclined from a vertical axis of the top plate within a first angle range; a main sensor mounting unit, engaged with a second end of the extendable boom, for mounting at least one sensor thereon, wherein the main sensor mounting unit is allowed to be inclined from a longitudinal axis of the extendable boom within a second angle range; a sensor module unit including the sensor mounted on the main sensor mounting unit; and a control module for controlling or supporting another module to control at least one of the extendable boom within the first angle range and the main sensor mounting unit within the second angle range.

A fire mitigation and/or public safety event detection device has a housing having a cavity and a plurality of varying sensors coupled within the cavity of the housing, and/or coupled to, or somehow connected or interfaced with the housing. The device and/or system further has a processor configured to determine, based upon outputs from the sensors, whether there is a fire/wildfire event or a public safety event or associated conditions. The processor is further configured to transmit data indicative of the sensors and alerts related to the fire event and/or the public safety event and/or associated conditions to one or more computing device(s) of utility personnel, authorized third parties, and/or first responders. An aggregated deployment of such fire mitigation and public safety event detection devices serves to create a web or network, thereby serving as a watchdog system within the associated deployment area(s).

One or more thermal images containing pixel-by-pixel radiation intensity data in two or more wavelength bands can be processed to accurately determine the location of fire within the image(s), regardless of the radiation-scattering effects of smoke. First, all pixels having radiation intensities above a fire threshold in the longer-wavelength band are classified as being aflame. Second, a threshold curve defining a fire threshold in the shorter-wavelength band is applied to the pixels, and those having radiation intensities above the fire threshold in the shorter-wavelength band are classified as being aflame. Third, at least the second group of pixels above is tested to see if each pixel classified as being aflame is part of a group of adjoining pixels which were all classified as being aflame, and if so, each such pixel is reclassified as not being aflame unless it also falls within the first group of pixels above.

A GPS tracking and mapping wild fire defense system network configured for defending homes and neighborhoods against threat of wild fire by proactively spraying environmentally-safe anti-fire (AF) chemical liquid on property surfaces to inhibit fire ignition and flame spread in the presence of wild fire. The GPS tracking and mapping wild fire defense system network includes: a command center in operable communication with a wireless communication network; and one or more GPS-tracked anti-fire liquid spraying systems, each having an integrated supply tank and a spray pump deployable at properties having building structures, for spraying the properties with environmentally-clean anti-fire chemical liquid using a spray nozzle assembly connected to said spray pump by way of a fluid connection. The system network further includes: a GPS system for transmitting GPS reference signals from a constellation of GPS satellites deployed in orbit around the Earth, to a GPS transceiver installed aboard each GPS-tracking anti-fire liquid spraying system, for GPS processing and GPS-coordinate location; and one or more mobile computing systems, each for use by a registered user including property parcel owners, spray contractors, and other stakeholders on the system network, to request and receive services supported by said system network. Each mobile computing system has a display screen supporting: messaging services; display of maps indicating where wild fires have been identified and mapped, tracked and ranked in terms of risk to the user and GPS-specified property; and scheduling of spray task to be performed, and recording tasks that been completed, and which are in progress, on the GPS tracking and mapping wild fire defense system network.
