Attorney Docket: 0006699.000002 SIGNAL DAMPENING AND BLAST MITIGATION DEVICE CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to U.S. Non-Provisional Patent Application Serial No. 18 / 818,769, filed on August 29, 2024, and U.S. Provisional Patent Application Serial No. 63 / 579,418, filed on August 29, 2023, which are hereby incorporated by reference in their entireties into this application. BACKGROUND Field
[0002] Embodiments generally relate to a counter weaponized drone device and method. Specifically, embodiments provide a signal dampening and blast mitigation device method for protecting human life and critical infrastructure. More specifically, various embodiments of the device and method can be used to counter the effects of a downed weaponized device by mitigating blast fragmentation and blocking signal transmission. Description of the Related Art
[0003] Current counter weaponized drone / UAS (C-UAS) technologies are oriented towards electronic location, identification, blocking, and disablement causing the drone to crash land.
[0004] Weaponized drones for use by drug cartels, terrorists, and militaries have surged significantly in the past few years. They range from State sponsored / manufactured weapons systems to small Commercial Off-The-Shelf (COTS) drones with improvised explosive payloads. Current estimates are that Ukraine is losing more than 10,000 drones per month with more than half being weaponized (LeMonde, 2023).
[0005] The focus of C-UAS technologies has been electronic warfare blocking, disrupting, and spoofing. Once a drone reaches the surface (i.e., ground, building, ship), it becomes a -1- IM-#10454304.1Attorney Docket: 0006699.000002 Public Security and Explosive Ordnance Disposal (EOD) problem and is largely treated as an Improvised Explosive Device (IED) response.
[0006] Water has long been used as blast protection to mitigate IEDs. Conventional blast protection designs are placed around typical ground ordnance or IEDs to neutralize blast fragmentation generated by the IED when it is detonated. Current C-UAS technologies do not have signal blocking capabilities, and therefore are limited in their mitigating capabilities. They also are not designed for rapid deployment to minimize the time spent inside the range of blast and fragmentation hazards.
[0007] Conventional signal jamming material is used extensively for blocking and includes pop-up buildings and bags. These materials do not have blast and fragmentation protective capabilities, and therefore are not a comprehensive C-UAS solution.
[0008] What is needed is a first responder device and associated mitigating method offering a simple process to disrupt the send / receive signal of the downed weaponized drone, while also providing a structure to offer explosive blast and fragmentation protection. SUMMARY
[0009] Embodiments provide a signal dampening and blast mitigation device which protects human life & critical infrastructure from downed weaponized devices carrying explosive payloads or intelligence, surveillance, and reconnaissance (ISR) sensors. Designed for rapid deployment by first responders, the signal dampening and blast mitigation device uses electromagnetic radiation (EMR) shielding, a remotely fillable liquid bladder, and a Cordura outer shell to mitigate explosive blast and fragmentation hazards. This method provides time to evacuate personnel in the blast and fragmentation area as well as protection to critical infrastructure.

[0028] FIG. 1 is a perspective view of a signal and dampening blast mitigation device according to an embodiment.
[0029] FIG. 2 is a perspective view of a hose assembly of the signal dampening and blast mitigation device, as shown in FIG.1, according to an embodiment.
[0030] FIG. 3 is a flow chart of a method of operation of the signal dampening and blast mitigation device, as shown in FIGS. 1 and 2, for mitigating the hazards of a downed weaponized device according to an embodiment. DETAILED DESCRIPTION
[0031] While the scope of the apparatus and the method will be described with several embodiments, it is understood that one of ordinary skill in the relevant art will appreciate that -6- IM-#10454304.1Attorney Docket: 0006699.000002 many examples, variations and alterations to the apparatus and method described here are within the scope and spirit of the embodiments.
[0032] Accordingly, the embodiments described are set forth without any loss of generality, and without imposing limitations, on the embodiments. Those of skill in the art understand that the scope includes all possible combinations and uses of particular features described in the specification.
[0033] The signal dampening and blast mitigation device, according to various embodiments, provides non-obvious advantages over conventional ordnance mitigation devices. Conventional devices typically use electronic circuitry to disrupt the operational signal (e.g., initiation / detonation) of downed weaponized drones or IEDs. The signal dampening and blast mitigation device, according to various embodiments, when properly placed over the downed weaponized drones or IED, disrupts the ability of the signal to initiate the firing train by acting as an electronic barrier. Once the bladder of the mitigating body is filled with water, the weight of the water in the bladder seals multiple faraday layers of the mitigating body over the downed weaponized drones or IED, thereby slowing the trajectory of material fragmentation and pushing downward any blast fragmentation from a detonated downed weaponized drone or IED. Water is an environmentally sound method for tamping as it is non- toxic and readily available. Accordingly, the signal dampening and blast mitigation device, according to various embodiments, offers public security representatives time to evacuate personnel and call emergency services.
[0034] The signal dampening and blast mitigation device is a comprehensive emergency response tool used to prevent RF signaling both to and from a downed weaponized drone (i.e., loitering drone) or an IED and to protect the surrounding area from blast fragmentation of the detonated device. According to various embodiments, the signal dampening and blast mitigation device offers three capabilities in a single tool: (1) prevention of the weaponized -7- IM-#10454304.1Attorney Docket: 0006699.000002 device from sending or receiving signals, (2) capability to flood the weaponized device and cause the electrical systems of the device to fail, and (3) protection from blast and fragmentation in the event of the detonation of the weaponized device.
[0035] FIG. 1 is a perspective view of a signal dampening and blast mitigation device according to an embodiment. FIG. 2 is a perspective view of a hose assembly of the signal dampening and blast mitigation device, as shown in FIG. 1, according to an embodiment. As shown in FIG.1, the device 10 includes two primary components: (1) the hose assembly 100, as further shown in FIG.2, and (2) the neutralizing body 200.
[0036] According to an embodiment, the hose assembly 100, as shown in FIGS. 1 and 2, includes the following components, positioned in series (as attached from a water source to a connection to the neutralizing body 200): (a) a universal connector 110, (b) an on / off valve 120, (c) a flow meter 130, (d) a check valve 140, (e) a relief valve 150, (f) a quick release connector 160 and a fill / drain hose 170.
[0037] According to an embodiment, the universal connector 110 of the hose assembly 100 is a Camlock connector varying in size based upon customer needs. In a preferred embodiment, the quick release connector 110 has a size of 1.5 inches, more preferably 2 inches, and more preferably 2.5 inches. The sizing variability of the universal connector 110 allows the neutralizing body 200 to be connected to a standard firefighting hose or a fire main (noting that the size of the fire main varies regionally). The sizing variability of the universal connector 110 also facilitates an easily removed connection that allows for the water bladder 240 of the signal dampening and blast mitigation device 10 to be conveniently emptied.
[0038] According to an embodiment, the on / off valve 120 of the hose assembly 100 is a gate valve that allows both water inflow, outflow, as well as variable adjustment. In operation, the on / off valve 120 is opened to allow the water supply to be turned on, thereby filling the water bladder 240. Upon filling the water bladder 240 to the appropriate level (as denoted by -8- IM-#10454304.1Attorney Docket: 0006699.000002 the flow meter / totalizer), the on / off valve 120 can then be closed to shut off the supply of water to the water bladder 240. The on / off valve 120 has three iteration possibilities: 1.5 inches, 2.0 inches, and 2.5 inches, based upon the desired size of the connection to the water source.
[0039] According to an embodiment, the flow meter 130 of the hose assembly 100 allows the operator to monitor the volume of water entering the water bladder 240. The water bladder 240 has a demonstrated volume capacity of 2,300 liters / 607 gallons. When the water volume reaches 2,300, as displayed by the flow meter 130, the operator turns off the on / off valve 120 and secures the water source. According to an embodiment, the flow meter 130 is powered by two double A batteries requiring bi-annual battery changing. In some embodiments, the flow meter 130 is a totalizer.
[0040] According to an embodiment, the check valve 140 of the hose assembly 100 is a one- way valve (towards the water bladder 240) that protects the flow meter from back pressure when filling the water bladder 240. According to an embodiment, the relief valve 150 of the hose assembly 100 is an over pressure valve (200 psi) that protects against pressure surges when filling the water bladder 240.
[0041] According to an embodiment, the quick release connector 160 of the hose assembly 100 is a Camlock connector varying in size based upon customer needs. In a preferred embodiment, the quick release connector 160 has a size of 1.5 inches, more preferably 2 inches, and more preferably 2.5 inches. The sizing variability of the quick release connector 160 allows the neutralizing body 200 to be connected to a standard firefighting hose or a fire main (noting that the size of the fire main varies regionally). The sizing variability of the quick release connector 160 also facilitates an easily removed connection that allows for the water bladder 240 of the signal dampening and blast mitigation device 10 to be conveniently emptied. The quick release connector 160 allows the hose assembly 100 to be quickly disengaged from the -9- IM-#10454304.1Attorney Docket: 0006699.000002 neutralizing body 200 to thereby allow the operator to quickly drain the water bladder 240 after use.
[0042] According to an embodiment, the fill / drain hose 170 of the hose assembly 100 is 100 feet or 33 meters long, such that the signal dampening and blast mitigation device can be deployed and used at a safe standoff while filling the water bladder 240. The signal dampening and blast mitigation device 10 is ideally suited to mitigate explosive devices under 5 pounds Net Explosive Weight (NEW), and reasonably suited to mitigate explosive devices under 10 pounds NEW. The length of the fill / drain hose 170 of 100 feet or 33 meters is chosen because it exceeds the standard minimum safety distances for an explosive charge of 5 pounds NEW. In an embodiment, the fill / drain hose may be 4 inches in diameter and may be made of TPU and is heat sealed for structural integrity.
[0043] As further shown in FIG. 1, the neutralizing body 200 includes: (a) an outer shell 210, (b) an EMR shielding layer 220, (c) a fragmentation layer 230, (d) a water bladder 240, (e) an EMR shielding layer Velcro loop 250, (f) an EMR shielding layer Velcro hoop 260, and (g) a plurality of securing loops 270. The outer shell 210, the EMR shielding layer 220, and the fragmentation layer 230 are sewn together to form a liner or blanket surrounding the water bladder 240. The EMR shield layer Velcro loop 250 and the EMR shielding layer Velcro hoop 260 are configured to seal the liner or blanket securing the water bladder 240 within the liner or blanket.
[0044] According to an embodiment, the outer shell 210 is comprised of a planar top surface 210a, a planar bottom surface 210b, and 4 planar side surfaces, 210c, 210d, 210e, 210f. In an embodiment, one of the 4 planar side surfaces 210f is comprised of two panels 210g, 210h, forming an access door to install the water bladder 240 and to prevent entry of any debris from a detonated downed, weaponized drone or IED, one panel 210g to which the EMR shielding layer Velcro loop 250 is affixed and the other panel 210h to which the EMR shielding layer -10- IM-#10454304.1Attorney Docket: 0006699.000002 Velcro hoop 260 is affixed. As shown in FIG. 1, side surface 210e of the outer shell 210 is configured to receive and connect to the hose assembly 100, and the side surface 210f is arranged on an opposing side of the outer shell 210 from the connection to the hose assembly 100.
[0045] The outer shell 210 is composed of Cordura fabric, more particularly, Cordura 1000 fabric, although other materials have been contemplated according to various embodiments, materials that can withstand tears, scuffs, and abrasions with the same capabilities as Cordura 1000, such as canvas or Kevlar-reinforced nylon.
[0046] According to an embodiment, each planar surface of the outer shell 210 is double folded and stitched to a respective EMR shielding layer 220 and respective fragmentation layer 230 with high strength thread. In some embodiments, each planar surface of the outer shell 210, EMR shielding layer 220, and the fragmentation layer 230 are double stitched together with high strength thread to form a single surface sheet, such that the top surface sheet, the bottom surface sheet, and the 4 side surface sheets can be stitched together to form a pouch for containing the water bladder 240 therein. The top and bottom surface sheets of the outer shell 210, EMR shielding layer 220, and the fragmentation layer 230 measure (L) 2.7 meters / 8.86 feet by (W) 2.7 meters / 8.86 feet, thereby having dimensions of a size to contain the water bladder 240 when it is filled to capacity. The choice of thread will have no blast mitigation effect and serves only to secure the layers to one another. It should be noted that other dimensional sizes of the outer shell 210, the EMR shielding layer 220, and the fragmentation layer 230 are contemplated to adjust for larger downed, weaponized drones and IEDs. The outer shell 210 made of Cordura serves as an additional fragmentation slowing mechanism as well as friction protection to the EMR shielding layer 220. The fragmentation layer 230 touches the water bladder 240. -11- IM-#10454304.1Attorney Docket: 0006699.000002
[0047] According to an embodiment, the EMR shielding layer 220 includes one faraday EMR shielding layer, more preferably two faraday EMR shielding layers. The two faraday EMR shielding layers may be constructed of woven copper and aluminum that are configured to disrupt and / or block electronic signals transmitted from and / or received by the downed, weaponized drone or IED. One of ordinary skill in the art would have understood that other electronic signal blocking materials may be used to construct the faraday EMR shielding layers 220 according to various embodiments.
[0048] According to an embodiment, the fragmentation layer 230 is made from heavy duty nylon webbing that serves two functions: (1) protecting the EMR shielding layer 220 and (2) slowing the expulsion of fragmentation in the event of an explosion. The combination of water contained in the water bladder 240 to serve as a tamping method combined with the nylon webbing of the fragmentation layer 230 to ensnare thrown fragmentation reduces potential travel of hazardous fragmentation over long distances away from the down, weaponized drone or the IED. The fragmentation layer 230 is double stitched to an outside surface of the EMR shielding layer 220. One of ordinary skill in the art would have understood that other materials may be used, which would serve the prescribed functions, to construct the fragmentation layer 230 according to various embodiments.
[0049] According to an embodiment, the water bladder 240 is constructed of thermoplastic polyurethane (TPU) having a thickness of 1 millimeter. The water bladder 240 measures (L) 2.5 meters / 8.2 feet by (W) 2.5 meters / 8.2 feet by (H) 30 centimeters / 12 inches. TPU allows for significant expansion when filled where the ideal operational volume is 2,300 liters / 607 gallons. One of ordinary skill in the art would have understood that other materials may be used, which would serve to accommodate the significant expansion of the water bladder 240, to construct the water bladder 240 according to various embodiments. It should be noted that -12- IM-#10454304.1Attorney Docket: 0006699.000002 other dimensional sizes of the water bladder 240 are contemplated to adjust for larger downed, weaponized drones and IEDs.
[0050] According to an embodiment, the EMR shield layer Velcro loop 250 and the EMR shielding layer Velcro hoop 260 are configured as a double flap, in which one fold provide an initial closure and then a second fold seals the water bladder 240 within the the outer shell 210.
[0051] According to an embodiment, the plurality of securing loops 270 include one or more securing loops 270 secured to each corner of the neutralizing body 200. More particularly, the neutralizing body 200 includes a pair of securing loops 270 at each corner, one being secured to a top surface corner of the neutralizing body 200 and the other secured to a bottom surface corner of the neutralizing body 200. According to an embodiment, the plurality of securing loops 270 are non-magnetic and are configured to allow the signal dampening and blast mitigation device when the water bladder 240 is filled to capacity to be moved by the operator when pulling the signal dampening and blast mitigation device using one or more of the plurality of securing loops 270, or to secure the neutralizing body 200 to the ground over the downed weaponized drone or IED in high winds or other heavy weather.
[0052] According to an embodiment, the signal dampening and blast mitigation device includes a separate portable bag for carrying the device to a site of the downed weaponized device or IED. The signal dampening and blast mitigation device may also include an operation and maintenance manual as well as recommended training with the Emergency Response Procedure (ERP).
[0053] The device, according to various embodiments, is designed to be used by first responders (e.g., military, police, firefighters, bomb disposal technicians), when arriving at the scene of a downed weaponized drone or IED, removing the signal dampening and blast mitigation device from a vehicle and walking to the ordnance, removing the signal dampening -13- IM-#10454304.1Attorney Docket: 0006699.000002 and blast mitigation device from a carrying bag, and placing the signal dampening and blast mitigation device directly over the top of the ordnance. The first responder then unfolds the device, and dependent upon weather conditions may also stake the device down or tie it down using the tie downs on the outer edges of the signal dampening and blast mitigation device. At this juncture, the ordnance is likely RF signal safe and cannot transmit or receive signals. The first responder can also decide whether he / she will flood the device by filling the water bladder to capacity, as discussed above (i.e., opening a relief valve), or not flooding the device (i.e., maintain the relief valve in a closed position). Flooding of ordnance has successfully been used for 80 years but is dependent upon conditions of the ordnance and local environmental conditions (i.e., water would cause other problems).
[0054] Next, the first responder connects the signal dampening and blast mitigation device, using a hose assembly, at a safe distance (K50), to a water source (e.g., hydrant, fire truck, or other available sources). Once the water bladder of a neutralizing body is filled (i.e., dependent upon the size of signal dampening and blast mitigation device, multiple sizes available), the downed weaponized device has a moderate blast and fragmentation veil of protection as well as signal protection.
[0055] FIG. 3 is a flow chart of a method of operation of the signal dampening and blast mitigation device, as shown in FIGS. 1 and 2, for neutralizing a downed weaponized device according to an embodiment.
[0056] As shown in FIG.3, the method provides for the deployment of a signal dampening and blast mitigation device at a site of a downed weaponized drone or IED, the signal dampening and blast mitigation device, as shown in FIGS. 1 and 2, including two primary components: (1) a hose assembly, as further shown in FIG. 2, and (2) a neutralizing body, as described in detail above. The method includes placing the neutralizing body of the signal -14- IM-#10454304.1Attorney Docket: 0006699.000002 dampening and blast mitigation device over the downed weaponized drone or IED, such that the neutralizing body completely covers the drone or IED (step 310). The method further includes extending the hose assembly of the signal dampening and blast mitigation device a distance of 100 feet towards a water source for filling a water bladder of the signal dampening and blast mitigation device (step 320), and then connecting the hose assembly to the water source (step 330). The method further includes filling the water bladder using the water source (step 340). The water bladder is filled by opening an on / off valve of the hose assembly (step 350). The operator of the signal dampening and blast mitigation device monitors a flow meter of the hose assembly to ensure that the water bladder is filled to a capacity of 2,100 liters and the hose is filled to a capacity of 200 liters, totaling 2,300 liters (step 360). The on / off value is turned to an off position, the hose is depressurized and removed from the water source (step 370). With the water bladder filled to capacity, the neutralizing body disrupts the ability of a remote signal to initiate the firing train of the downed weaponized drone or IED by acting as an electronic barrier, while the weight of the water in the bladder seals a faraday liner of the neutralizing body over the downed weaponized drones or IED, thereby slowing the trajectory of and pushing downward any blast fragmentation from a detonated downed weaponized drone or IED.
[0057] Upon neutralization of the downed weaponized drone or IED, a quick release connector of the hose assembly is disconnected from the water bladder of the neutralizing body, thereby causing the water in the water bladder to drain out (step 390). A plurality of securing loops are arranged at each corner of the signal dampening and blast mitigation device, further enabling the operator to raise the neutralizing body to assist in the drainage of the water from the water bladder.
[0058] Embodiments address the absence of an existing protocol for mitigating a signal or blast of a downed weaponized drone or IED. The signal dampening and blast mitigation device, -15- IM-#10454304.1Attorney Docket: 0006699.000002 according to various embodiments, provides a solution for saving lives and protecting critical infrastructure while the downed weaponized drone or IED is being neutralized.
[0059] The signal dampening and blast mitigation device offers a rapidly deployable, agile, and scalable response to a wide range of downed weaponized devices and IEDs. As swarming becomes an increasingly relevant threat, it is critical that some drones be recovered to exploit the drone to determine counter swarm leverage points. The signal dampening and blast mitigation device is simple to deploy, mobile, and cost effective against both small and large attacks. Signal dampening and blast mitigation devices that are not destroyed in the response process can be re-used.
[0060] Extensive laboratory testing has been performed on modeling blast and fragmentation capabilities. Explosive devices vary tremendously based upon the types of explosive fillers (e.g., TNT) as well as the type of fragmentation (e.g., shape charge, ball bearings). In addition to water used for blast fragmentation protection, embodiments of the signal dampening and blast mitigation device include a water-filled bladder that helps mitigate the speed of travel of blast fragmentation, as well as one additional layer of fibrous Cordura- type material to slow fragmentation dispersion. The explosive calculations are based upon standard RE factors (RE 1=1 pound TNT). The blanket size can be adjusted to mitigate different size categories of weaponized drones, ranging from small category 1 drones to large category 3 drones.
[0061] Various embodiments contemplate frequency ranges that will jam the types of signals transmitted from and received by the downed weaponized devices.
[0062] Signal blocking benefits of this design are maximized by layering. Each layer increases the protective capability of the signal dampening and blast mitigation device because signals cannot be transmitted from or received at the downed weaponized device. When filled with water, for example, an additional blocking factor of water is applied. Functionally, no -16- IM-#10454304.1Attorney Docket: 0006699.000002 signals have penetrated four layers of signal jamming material with water, therefore preventing the downed weaponized device from relaying its location, and in particular sending signals indicating its static movement to a home station, so that remote destruction can be avoided (sometimes, drones can be remotely detonated if they are showing they have been downed). Additionally, this configuration blocks the device operator from sending signals to the downed weaponized device, preventing detonation of the device and mitigating the blast and fragmentation for material exploitation.
