Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to unmanned aerial vehicles. More specifically, the present invention relates to an unmanned aerial vehicle with a non-lethal neuromuscular incapacitation system that delivers an electric pulse, mace, marking dye or other non-lethal device to incapacitate a person.

Description of the Related Art

In recent years, unmanned aerial vehicles (UAVs), more commonly known as drones, have been used by law enforcement agencies for a number of specialized purposes including search and rescue operations, traffic collision reconstruction, crime scene analysis, general surveillance and crowd monitoring. UAVs have also been used by law enforcement officers to investigate suspects and locate active shooters that are believed to be “armed and dangerous” while maintaining a safe distance. While this gives officers real-time, actionable intelligence to use to assess the threat and formulate a strategy to respond, it still requires officers to be put into harm's way to diffuse the situation and subdue the shooter.
Accordingly, there is a need for an unmanned aerial vehicle that carries with it a non-lethal neuromuscular incapacitation system that is capable of not only providing officers with intel to assess the threat, but the tools to diffuse the threat without putting officers in harm's way.

SUMMARY OF THE INVENTION

It is therefore an objective of the present invention to provide an unmanned aerial vehicle that carries a non-lethal neuromuscular incapacitation system that is capable of being deployed remotely by officers via a handheld remote control.
The present invention meets this objective by providing an unmanned aerial vehicle that carries an on-board non-lethal incapacitation system.

The battery 20 powers the electric motors 15 coupled to the propellers 14 as well as the camera 16 and flight control electronics 18.
A protective cage 36 surrounds the UAV 10 and is attached to the UAV body 12 by a plurality of connectors such as leaf springs 38 having a first end attached to the protective cage 36 and a second end attached to the UAV body 12. The protective cage 36 is preferably formed of a plurality of criss-crossed wires that surround the UAV body 12, but can consist of any configuration that surrounds the UAV body 12 and propellers 14 providing a protective cage. Preferably, the cage 36 is spherical or ball-shaped, although other shapes are certainly contemplated.
A plurality of stinging stickers 40 are attached to the periphery of the cage 36. Each of the stinging stickers 40 includes a plurality of metal hooks or barbs 42 that, when they come into contact with an object such as human skin, engage and penetrate the surface of the skin. Although numerous configurations of stinging stickers could be used, FIG. 1 depicts two different types of stinging stickers 40 a, 40 b, shown in FIG. 1 in a alternating pattern. The first type of stinging sticker 40 a includes a plurality of metal hooks or barbs 42 a that are electrically coupled to the positive terminal of a power source 44, while the plurality of metal hooks or barbs 42 b on the second type of stinging sticker 40 b are electrically coupled to the negative terminal of the power source 44 such that, when activated, an arc of electricity is generated between adjacent stinging stickers 40 a, 40 b. The stinging stickers 40 a, 40 b are activated when the barbs 42 a, 42 b are in close proximity to the target person such that the arc of electricity delivers a charge to the suspect once the barbs 42 a, 42 b are in close proximity to the skin of the target. The plurality of metal barbs 42 a are electrically coupled to the positive terminal of a high voltage pulse supply 44 that is carried on the UAV body 12 via electrical leads 46. A plurality of stinging stickers 40 a may be provided and connected in series as shown in FIG. 1 . The second type of stinging strikers 40 b include a plurality of metal hooks or barbs 42 b located in a central area surrounded by a surface with an adhesive thereon.
An alternative embodiment of the present invention is shown in FIG. 2 . Many of the components of the UAV 10 are the same or similar to those in the first embodiment and like reference numerals are used here to indicate like component parts. The UAV according to the second embodiment includes a RF power supply and RF transmitter 50 that is capable of transmitting a narrow beam of electromagnetic energy to heat the skin without causing any permanent damage. The beam is sent out at the speed of light by the transmitter. An intense burning sensation continues until the transmitter is turned off or the targeted individual moves outside of the beam's range.
A further alternative embodiment of the invention is shown in FIG. 3A and FIG. 3B. Again, many of the components of the UAV 10 are the same or similar to those in the previous embodiments and like reference numerals are used here to indicate like component parts. The UAV according to the third embodiment includes a mechanism for discharging a liquid or powder substance at the target. The liquid/powder discharging mechanism includes one or more reservoirs 60 a, 60 b for holding the liquid or powder to be discharged. A pump 62 a, 62 b is associated with each reservoir 60 a, 60 b to draw the liquid or powder from the reservoirs 60 a, 60 b and direct it into tubes 64 a, 64 b. The free ends of tubes 64 a, 64 b are positioned at the periphery of the cage 36 to discharge the liquid or powder at the target when the UAV is in close proximity. Power is provided to power the pumps 62 a, 62 b by the main battery 20. A high voltage power supply 66 has a positive post connected by a lead wire to the first tube 64 a and a a negative post connected by a lead wire to the second tube 64 b. The first and second tubes 64 a, 64 b are preferably formed from an electrically conductive material such that when the stinging liquid is discharged from the end of the tubes 64 a, 64 b it forms a mist which become electrically charged upon actuation of the high voltage power source via electricity passing through the electrically conductive tubes 64 a, 64 b and the mist which spans the area around the free ends of the tubes 64 a, 64 b.
According to one aspect of the third embodiment, the liquid used is a stinging liquid and the liquid reservoirs are conductive liquid reservoirs, one being positively charged and the other negatively charged. Alternatively, the liquid reservoirs could contain mace. Still further, a marking dye could be contained in the reservoirs such that an ultraviolet or colored dye is discharged from the ends of the tubes 64 a, 64 b.
A fourth embodiment of the present invention, as shown in FIGS. 4A-4C, includes a rotary sting arm 70 connected to the UAV body 12 by a rotary brush high-voltage connection 72 and powered by a sting arm motor 73 mounted at or near the center of the UAV body 12. The main components of the UAV 10 are the same as in previous embodiments were like reference numerals indicate like components. Each end of the rotary stinging arm 70 has a stinger element 71 a, 71 b that is configured to deliver a stinging charge when it comes into contact with the skin of a target. A high voltage power supply 74 positioned on the UAV body 12 supplies power to the stinger elements 71 a, 71 b. A first lead wire 76 a has a first end attached to a positive post of the high voltage power supply 74 while a second lead wire 76 b has a first end attached to a negative post of the high voltage power supply. The lead wires 76 a, 76 b are connected to electrical contacts 72 a, 72 b that are a part of the rotary brush high-voltage connection 72 so that power can be delivered to the stinger elements while the rotary sting arm 70 is in rotary motion without the lead wires 76 a, 76 b becoming entangled. The distal end of the lead wires 76 a, 76 b are connected to stinging barbs 78 a, 78 b, respectively, that are positioned at the outer ends of the stinger elements 71 a, 71 b.
A fifth embodiment of the present invention, shown in FIGS. 5A-5B, includes a telescoping stinger 80 that can be fired at a target within range of the UAV body 12. The telescoping stinger 80 may be equipped with an electrode barb 82 at the end thereof which is connected by a wire 83 to a high voltage pulse power supply 84. A spool 85 may also be provided about which the wire 83 can be wound, and, subsequently unwound as the telescoping stinger 80 with the end of the wire 83 attached is fired at and moves toward the target. The telescoping stinger in inserted into a barrel that has a spring 86 located therein. The stinger 80 compresses the spring 86 and locks the stinger 80 into position with the spring 86 compressed. When the user actuates a trigger switch (not shown) on the handheld remote control unit 24, the spring 86 is released and the stinger 80 fired toward the target.
FIG. 5C shows an alternative firing mechanism for the fifth embodiment wherein a pair of telescoping stingers 80 a, 80 b having electrode barbs 82 a, 82 b, respectively, are loaded into barrels and have electrical lead wires 83 a, 83 b which connect them to a high pulse power supply 84. Spools 85 a, 85 b may also be provided about which the wires 83 a, 83 b can be wound, and, subsequently unwound as the telescoping stingers 80 a, 80 b with the end of the wires 83 a, 83 b attached are fired at and move toward the target. An air compressor 87 and valve controller 88 serve to open and close valves 89 a, 89 b and deliver a burst of compressed air to the barrel(s) causing the stinger(s) 80 a, 80 b to be discharged toward the target upon actuation of the trigger switch (not shown) by the user on the handheld remote control unit 24.
