DETAILED DESCRIPTION

[0028] Reference will now be made in detail to some embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0029] FIG. 1 is a block diagram of a wildfire defense system 100. The system 100 includes pump system 101 having a first pump P1 and a second pump P2. The first pump P1 pumps fluid from a first tank 102 over a first fluid path to a mixing valve (MV). The second pump P2 pumps fluid from a second tank 103 over a second fluid path to the mixing valve (MV). In various embodiments, the first tank 102 is configured to store a first fluid, such as water. The second tank 103 is configured to store a second fluid, such as a fire retardant gel.

[0030] The system also includes a controller 104, which is operatively coupled to both the first pump P1 and the second pump P2, as well as to the mixing valve (MV). The controller 104 comprises at least one of a CPU, processor, state machine, programmable memory, logic, interface hardware, discrete hardware, and any software configured to implement the functions of the controller 104 described herein. In some embodiments, the controller 104 is configured to control the pumping operations of the first pump P1 and the second pump P2 of the pump system 101. The first pump P1 pumps the first fluid from the first tank 102, and the second pump P2 pumps the second fluid from the second tank 103. The controller 104 regulates the flow and mixture of fluids from the first 102 and second 103 tanks at the mixing valve (MV) according to a configurable ratio, thereby generating a third fluid that is provided at an output port of the mixing valve (MV). In one embodiment, the third fluid is a mixture of the first fluid and the second fluid, and the ratio of the first fluid to the second fluid in the third fluid is adjustable by the controller 104 based on specific requirements or conditions.

[0031] The system further includes one or more fixed location sprayers 105 and 106, which are coupled to the output of the mixing valve (MV). In one embodiment, a first control valve (V1) couples fixed location sprayers 105 and 106 to receive and spray the third fluid from the mixing valve (MV). The fixed location sprayers 105 and 106 are configured to disperse the mixed fluid over a predetermined target area. In one embodiment, the fixed location sprayers 105, 106 are remotely controllable by the controller 104.

[0032] The system further includes manual sprayers 107 and 108, which are coupled to the output of the mixing valve (MV) by a second control valve (V2). The manual sprayers 107 and 108 are used to manually spray the third fluid over any desired area as determined by users that operate the sprayers 107 and 108. In one embodiment, the controller 104 is configured to control the operations of the control valves V1 and V2. In another embodiment, the control valves V1 and V2 are manually operated by a user.

[0033] In this embodiment, the system 100 also includes a power system 109. The power system 109 supplies energy to the controller 104 and pumps P1 and P2. The power system 109 ensures that the system can operate independently of external power sources. In various embodiments, the power system 109 comprises batteries, solar panels, power generators and/or other stand-alone power systems. In other embodiments, the power system 109 is connected to a mains power line and the system 100 is fixed and not portable.

[0034] In this embodiment, the system 100 also includes a communication system 110. The communication system 110 is configured to receive activation signals 111 and/or control signals 112. The activation signals 111 are configured to remotely switch on the system 100, allowing for a rapid response to emerging wildfire threats. The control signals 112 are configured to control various features and functions of the system 100. The control signals 112 may be used to control the mixing ratio of the first and second fluids, the operations of the pumps P1 and P2, and/or the operation of the valves V1 and V1 or the sprayers 105 and 106.

[0035] In one embodiment, the first tank 102, the second tank 103, the mixing valve (MV), the first pump P1, the second pump P2, the controller 104, and the one or more sprayers 105-108 are attached to a movable assembly, which can also be referred to as a trailer. This movable assembly provides mobility to the system 100, allowing it to be moved to different locations as the risk of a wildfire changes.

[0036] In one embodiment, the system operates to disperse five-hundred (500) gallons of water in the first tank 102 in about five (5) minutes. The system can be operated longer if the first fluid path that receives the output of the first tank 102 is hooked up to a more substantial volume of water, such as a pool, hydrant, or lake. In the absence of wind or trees one embodiment can spray an area of about 2 acres of land with the fire retardant spray that is output from the mixing valve. In one embodiment, one or more of the sprayers 105-108 can be remotely controlled through wireless commands received by the controller from the communication system 110. The power system 109 can be either a stand-alone power system or connected to a power grid to receive continuous power from a power utility or other source.

[0037] Additionally, the wildfire defense system 100 includes a system flush and/or rehydrate mode, a thermogel tank recirculation mode, and a mineral oil clean and feed mode. In the system flush and/or rehydrate mode, various tubes and components of the wildfire defense system 100 are flushed with water or other fluids. In the thermogel tank recirculation mode, thermal gels stored in the second tank 103 are recirculated through the system 100. It is generally undesirable for thermal gel to remain in the second tank 103 indefinitely. This mode allows for the thermal gel to be recirculated and/or agitated remotely or in accordance with a preconfigured schedule. In the mineral oil clean and feed mode, the thermal gel is drained from the second tank 103, mineral oil is added to the second tank 103, and cycled through tubing of the system 100. This mode is typically activated at the end of fire season and ensures that the wildfire defense system 100 is maintained fresh with mineral oil when not in fire season.

[0038] In accordance with another novel aspect, no water or water-like fluid enters the second fluid path. The system 100 is constructed such that no water or non-mineral based fluid enters any fluid path between the second tank 103 and the mixing valve (MV). Only fire retarding, fire suppressing, or mineral oil is permitted to enter the second fluid path between the second tank 103 and the mixing valve MV. The separation of water or water-like fluid from channels between the second tank 103 and the mixing valve (MV) ensures that a reliable and predictable amount of the second fluid enters the mixing valve (MV) to achieve desired mixing ratios.

[0039] FIG. 2 is a side view of a wildfire defense trailer 200 in accordance with one embodiment. The trailer 200 is configured to secure and transport the components of the wildfire defense system 100. The trailer 200 includes control panels 201A-C, which are mounted on the side of the trailer. In various embodiments, the control panels 201A-C are coupled to or include the controller 104 and provide operational control and monitoring capabilities for the wildfire defense system 100. The trailer 200 also includes pumps P1 and P2, which are situated to facilitate the movement of fluids from the tanks 102 and 103. In various embodiments, the pumps P1 and P2 are configured to pump a first fluid from a first tank 102 to a first fluid input port of a mixing valve (MV), and to pump a second fluid from a second tank 103 to a second fluid input port of the mixing valve (MV).

[0040] The controller 104 is configured to control operations of the first P1 and second P2 pumps. The controller 104 is configured to combine the first fluid stored in the first tank 102 with the second fluid stored in the second tank 103 according to a configurable ratio, thereby generating a third fluid that forms a fire retardant spray.

[0041] The trailer 200 also includes a protective housing 205 that secures and protects an engine, battery, generator, and the pumps P1, P2. In various embodiments, the generator is part of a power system configured to supply power to the components of the wildfire defense system. The power system provides stand-alone power to ensure that the system 100 can operate independently of external power sources, thus providing a reliable source of energy for the remote operation of the system 100. In the example of fixed embodiments where the wildfire defense system 100 is stationary, the power system is coupled to a power grid to receive power directly from a power utility.

[0042] Trailer wheels 203 support the trailer for mobility, and a stabilizing leg or jack 204 is deployed to secure the trailer in a stationary position during operation. A mounted sprayer or nozzle 107 is positioned at the top of the trailer, ready to disperse fire retarding or suppressing fluids over a selected geographic region. In some embodiments, one or more sprayers, which include the mounted sprayer or nozzle 107, are connected to the mixed fluid output port of the mixing valve and configured to spray the mixed fluid over a selected geographic region.

[0043] A method for wildfire defense is provided that includes storing a first fluid in a first tank, such as the first fluid tank 102 shown in FIG. 2. This first fluid is stored in the first tank 102 until it is ready to be used in the firefighting process. Similarly, the method also includes storing a second fluid in a second tank, such as the secondary tank or storage 103 depicted in FIG. 2. This second fluid is stored separately from the first fluid until it is ready to be mixed with the first fluid.

[0044] The method includes controlling a pump system and a mixing valve to combine the first fluid stored in the first tank 102 with the second fluid stored in the second tank 103 according to a configurable ratio, thereby generating a third fluid. The pump system includes the pumps P1 and P2 shown in FIG. 2, which are configured to pump the first fluid from the first tank 102 to a first fluid input port of the mixing valve (MV), and to pump the second fluid from the second tank 103 to a second fluid input port of the mixing valve (MV).

[0045] The method also includes outputting the third fluid from one or more sprayers, such as the mounted sprayer or nozzle 107 depicted in FIG. 2. These sprayers are connected to the output of the mixing valve and are configured to spray the mixed fluid over a selected geographic region. In various embodiments, the first tank 102, the second tank 103, the pump system 101, and the mixing valve MV are mounted on a transportable structure, such as the trailer 200 shown in FIG. 2. This transportable structure allows the system and methods to be operated in a variety of locations, providing flexibility in the deployment of the wildfire defense system.

[0046] In various embodiments, the method further includes supplying power from a stand-alone power source to the pump system. The power source is also attached to the transportable structure within the protective housing 205 and includes a generator, battery, and engine. The power source provides the energy that is used to operate the pump system 101, ensuring that the pump system 101 can function effectively in remote locations to move the fluids through the system 100.

[0047] FIG. 3 is a diagram of an embodiment of a fluid handling system for use with the wildfire defense system. The main fluid tank 102 is connected to the pump P1 driven by engine 301, which is powered by a generator or power unit, to move fluid through the system.

The 35 gallon gel tank is an integral component of the wildfire defense system, contributing to its functionality and effectiveness in wildfire defense.

[0082] FIG. 15 is a flowchart of a method 1500 in accordance with one novel aspect. The method 1500 comprises several steps for operating the system 100, including storing a first fluid in a first tank, storing a second fluid in a second tank, controlling a pump system and a mixing valve to combine the first fluid stored in the first tank with the second fluid stored in the second tank according to a configurable ratio, thereby generating a third fluid, and outputting the third fluid from one or more sprayers. The first tank, the second tank, the pump system, and the mixing valve are attached to a transportable structure, allowing for the method to be implemented in a variety of locations.

[0083] In some embodiments, the first fluid is water and the second fluid is a fire retardant gel. The pump system includes a first pump and a second pump, wherein the first pump draws the first fluid from the first tank, and the second pump draws the second fluid from the second tank. The mixing valve is configured to mix the first fluid and the second fluid in a configurable ratio, thereby generating a third fluid that is a mixture of the first fluid and the second fluid. The third fluid is then output from one or more sprayers, which are configured to disperse the third fluid over a selected geographic region.

[0084] In various embodiments, the method further comprises receiving an activation signal, wherein the third fluid is generated in response to the activation signal. This activation signal remotely switches on the system 100, allowing for the rapid response to emerging wildfire threats. The method also comprises setting the configurable ratio to a desired value, allowing for the adjustment of the ratio of the first fluid to the second fluid in the third fluid based on specific requirements or conditions.

[0085] In some embodiments, the method further comprises supplying power from a power source to the pump system, wherein the power source is attached to the transportable structure. This power source provides the energy that is used to operate the pump system, ensuring that the pump system can function effectively to move the fluids through the system 100. The method also comprises moving the transportable structure while outputting the third fluid from the one or more sprayers, thereby distributing the third fluid throughout an area surrounding the transportable structure. This operation allows for the efficient and effective distribution of the third fluid, providing a protective layer against wildfires over a large area.

[0086] In one embodiment, the method 1500 for operating a wildfire defense system comprises the following steps.

[0087] At step 1501, a notification is received of an approaching wildfire. The notification may be received by the satellite communication module 401 and passed to the controller 104, so that information about the approaching fire can be provided to a user.

[0088] At step 1502, the wildfire defense system is relocated to a geographic region to be defended from the approaching wildfire. Based on the information in the received notification, the user may move the system to a designated area that needs protection from the approaching fire.

[0089] At step 1503, one or more sprayers are positioned as needed to defend the geographic region. The user may position the sprayers to spray fire retardant over a specific region to be protected.

[0090] At step 1504, the system is powered up with its stand-alone power system.

[0091] At step 1505, the valves are set to mix the appropriate ratio of fluids in the first and second tanks to produce the desired ratio of fire retardant fluid. The mixed fluid is then directed by the valve positions to the appropriate sprayers.

[0092] At step 1506, the pumps are activated to start spraying the mixed fluid (fire retardant) to protect the identified geographic region.

[0093] FIG. 16 is a diagram showing operations of a system 1600 using the wildfire defense system 100 to protect structures. A remote controlled vehicle or drone 1601 operates to position the wildfire defense system 100 at a desired location or navigate through a pre-configured or learning-based path. The system 100 may be positioned to defend a structure 1604 from wildfires.

[0094] A fire detection system 1603 comprising any suitable type of fire detection apparatus detects the presence of a wildfire 1606. The detection system 1603 determines that the detected wildfire is moving in the direction of the structure 1604. When the wildfire 1606 gets within a selected distance 1605 from the structure 1604, the detection system 1603 utilizes a communication system 1602 to send activation and control signals 111 and/or 112 to the wildfire defense system 100. The activation and control signals 111 and 112 operate to activate the wildfire defense system 100, set a control valve, set a mixing ratio for the fire retardant, and set the sprayers to spray the mixed fire retardant 1607 over the structure 1604.

[0095] In one embodiment, the remote controlled vehicle or drone 1601 includes a processor, a memory, a Light Detection and Ranging (Lidar) sensor, a network interface, a machine learning system, and a camera. The memory stores machine readable instructions that when executed by the processor cause the drone 1601 to navigate around a property thereby positioning the wildfire system 100 at desired locations on a property. The camera and Lidar sensors may detect and map structures on a property. The machine learning system is trained to detect and identify high risk structures from high resolution images and point cloud data generated from the camera and Lidar sensors. The machine learning system uses one or more neural networks, Generative Adversarial Networks (GANs), and/or Variational Autoencoders (VAEs) to predict where, when, and how to apply fire retardant to structures.

[0096] Thus, the system 100 operates to receive information about detected wildfires, determine structures or regions that may be in danger, receive activation and control signals to the defense system 100, and begin spraying structures or regions with mixed fire retardant well before the fire arrives at the location of the protected structures or region.

[0097] FIG. 17 is a diagram showing remote and automated operation of the wildfire defense system 100. A device 1610 remotely controls automated operation of the wildfire system 100 over a network 1620.

The status interface 1615 presents status information of the wildfire defense system 100, such as fluid levels in tanks, battery charge information, energy consumption information, location information, log operating and maintenance history, and any other information pertinent to operating and maintaining the wildfire defense system 100. The sensor interface 1616 provides sensor data to the user 1612, such as temperature, image, or fluid level, audio information, or any other sensor data available from the wildfire defense system 100. In one embodiment, the sensor interface shows live stream image and/or video data, temperature at or near the property, and/or audio collected at the property.

[0099] In operation, the user 1612 downloads a software application 1617 onto the device 1610. The software application 1617 presents the user interface 1611 onto the device 1610. The software application 1617 processes user input provided via the user interface 1611 and generates control information 1618. The control information 1618 is generated and communicated to the wildfire defense system 100 via the network 1620. The control box 201B (shown in FIG. 2) may communicate with the device 1610 over the network 1620. Sensor and status information 1619 is communicated from the wildfire defense system 100 over the network 1620 and onto the device 1610 and presented via the status interface 1615 and sensor interface 1616.

[0100] In one embodiment, the user 1612 is an owner of structure 1604 present on a property of the user 1612. In accordance with at least one novel aspect, the user 1612 is able to remotely control wildfire defense system 100 while safely away from the property during the event of a wildfire. The user 1612 does not need to remain on their property or near structure 1604 to protect their property against wildfires. The user 1612 is able to activate and monitor wildfire defense system 100 remotely and away from danger.

[0101] In various embodiments, a third party entity 1630 receives information from the wildfire defense system 100. The third party entity 1630 is any entity that is provided access to sensor and status information 1631, such a firefighting station, a government entity, such as California Department of Forestry and Fire Protection, or another entity associated with collecting information about wildfires. The third party entity 1630 is configured to receive sensor and status information 1631 from the wildfire defense system 100 over the network 1620. For privacy, the user 1612 is able to control what information is available to third party entity 1630. The third party entity 1630 shares and uses such information to protect property, land, and others from active or imminent wildfires.

[0102] The wildfire defense system 100 optionally includes additional sensors 1640. In this example, the wildfire defense system 100 includes a thermal sensor 1641, a camera system 1642, a fluid level sensor 1643, and an audio system 1644. The thermal sensor 1641 uses infrared temperature sensing or other techniques to sense temperature at or near the wildfire defense system 100. The wildfire defense system 100 uses sensed temperature information in operation to protect structures and to communicate the temperature information over the network 1620.

[0103] The camera system 1642 includes one or more image sensors that capture image and/or video. The image and/or video provide useful information about status of property and surrounding structures and also provide guidance to propulsion systems operable to navigate the wildfire defense system 100. In one embodiment, the remote controlled vehicle or drone 1601 shown in FIG. 16 uses the image and/or video data to control the position of the wildfire defense system 100. In one example, the thermal sensor data and image data are used by a machine learning system to navigate a property, identify structures at risk, and automatically disperse fire retardant onto detected structures.

[0104] The fluid level sensor 1643 provides fluid level information of water, thermal gels, fire retardant/suppressant materials, or any other fluids that cycle through the wildfire defense system 100. In embodiments where the wildfire defense system 100 is mobile and includes tanks, such as tanks 102 and 103 of FIG. 1, the fluid level sensor 1643 provides information of fluids remaining in the tanks. In one embodiment, if the first tank 102 is running low on water, or if the second tank 103 is running low on fire retarding gel, the user 1612 is notified. In embodiments where the wildfire defense system 100 is fixed or connected to a dedicated tank or fluid source, the fluid level sensor 1643 provides information of remaining fluid in the tank or fluid source. If the wildfire defense system 100 is fixed and connected to a dedicated tank or pond, the fluid level sensor 1643 indicates when the fluid levels of the source are low.

[0105] The audio system 1644 includes microphone or speakers and allows the wildfire defense system 100 to detect and broadcast audio detected at the property and generate audio alerts or other output provided from a remote station. In one embodiment, the wildfire defense system 100 outputs an alarm notifying neighboring properties of potential wildfire risk. In another example, the wildfire defense system 100 provides audio data collected via microphone and streams the audio data to the user 1612 or other interested parties to remain informed on what is occurring on the property.

[0106] Although certain specific embodiments are described above for instructional purposes, the teachings of this patent document have general applicability and are not limited to the specific embodiments described above. Accordingly, various modifications, adaptations, and combinations of various features of the described embodiments can be practiced without departing from the scope of the invention as set forth in the claims.
