Electric projection weapons system

Abstract

The invention is a weapon/protection system that generates two or more channels of physical medium in which travels an electric current. The current circulates though the channels due to their impedance being lower than that of air. From the generated electrical potential difference resulting at the target, the current can mildly shock, stun or fully paralyze a subject; therefore the device can be used as a weapon or deterrent for entry.

Description

SUMMARY

The system differs from all previous devices by incorporating at least one directionally controlled nozzle to create a controlled impedance intersection point at the target. This provides a novel feature for precisely controlling the distance at which the effect of the weapon (shock) occurs.

By setting up this condition rapidly and/or by combining multiple media steams, a raster much like the type used to form an old fashioned CRT television image can be used to create invisible electrified fences, walls and or 3D structures like cages.

Another improvement is the possible use of a modulating viscosity of the medium. By using the unique physical properties of some compounds that change their viscosity in a fast and defined way, fluid exit conductivity and breakdown can be controlled. Examples of viscosity modulation can be achieved via thermal, electromagnetic fields or other means. The system is designed to maintain the medium in a thinner (liquid like) state inside the device while making it thicker (gel or solid like) when propelled outside. This partial or total material phase change contributes to extend the continuous laminar jet length (the length without forming droplets) and thus providing an improved conductive medium path for electric current allowing the reach of more distant targets.

The media are typically water ionic gel solutions or very low melting point alloys. It is projected through a small diameter long metal tube that provides laminar flow, slowly coerced and then exited at high velocity. The generated streams join within breakdown voltage at the target and a shock of controllable power can be imparted on the target (subject).

Unlike previous patents (patents U.S. Pat. No. 5,169,065 A and U.S. Pat. No. 7,676,972B2) the two streams of fluid are not projected in parallel or uncontrolled lines; those patents also never made use of controlled viscosity to provoke quasi or total phase to solid once in the air.

BACKGROUND

Solutions containing salts or acids are known to be conductive. For example a car battery's electrolyte is highly conductive. In this invention, we use this same basic liquid conductivity principle, but at a much lower and thus safer concentration. Unlike a car battery, the preferred embodiment uses higher voltages and a fluid medium that is only temporarily projected.

The acceptance of electric weapons by law enforcement is well established in many countries because it is an effective and a non-lethal means for control and neutralization of a threat. It is simple to use, causes virtually no collateral damage, and is relatively accurate. Despite obvious advantages some aspects of existing systems are operationally challenging. In current embodiments reloading is not possible or practical without full service (based on projected wire conductor and springs). Furthermore its use is more constraining in crowded areas given wire deployment along in a linear path (like a bullet's trajectory).

The invention overcomes these drawbacks by providing multiple shots, enables the capability of multiple or continuous reloading (through refueling of physical medium fluid/solution) and can target only in a controlled spatial volume (though jet convergence). This opens new possibilities for standalone operation (surveillance and active defense devices) and drone mounting (low recoil).

DETAILED DESCRIPTION AND PRINCIPLE OF OPERATION (PREFERRED EMBODIMENT)

• 1. Operation of the device is depicted on the overall (FIG. 2A to 2C), functional (FIG. 3) and operation (FIG. 9) diagram.
• 2. Two or four isolated reservoirs (120,121, 124,125) contain special high conductance ionic solutions. Reservoirs can be pressurized directly by a pump or indirectly by a piston or a bladder. See FIGS. (6 through 8).
• 3. In a direct pressurized reservoir system (156), the fluid is pumped by a high pressure pump (126) and pressure is maintained by a confined inert gas behind a diaphragm (127). The fluid being quasi incompressible forces pressurization of the gas, until the fluid is ready for release. See FIGS. (4 and 6).
• 4. In an indirect pressurized reservoir system (157), forced volume variation induces a fluid pump pressure. In this case a piston type (128); or a bladder type (129); a gas pressure generator (131) (see points 7 and 8) is used to produce the volume variation. In the case of a mechanically driven piston (130); the drive is achieved with a motor. In such embodiments, the fluid experiences low to high pressure states before release. See FIGS. (5 and 7).
• 5. More specifically, the indirect pressurized reservoirs (157), the pressure generation can be established with:
  • a. Two or four pistons that move fluid from one end from pressure that occurs on the other piston's end (128). See FIG. (7).
  • b. Two or four confined bladders move the fluid on one end from pressure variation that occurs between the bladder's membrane and a rigid confinement chamber (129). See FIG. (7).
  • c. Two or four pistons that move from a motor armed springs with a magnetic actuated released mechanism through a dielectric connecting rod (130). See FIG. (8).
• 6. The system contains: a mechanical valve set (122)(149)(146)(153) and a pump set (134)(152)(153) that are used to dispatch fluid (this may also be a gas or oil) for the operation of the dual or quad reservoirs (156,157). The system synchronizes: one high pressure fluid pump (126) or (on an indirect pressurized reservoir sub-system) one gas pressure generator. The valve sequence is driven by the controller (109). See FIGS. (3, 4 and 5).
• 7. In an indirect pressurized reservoir sub-system, exception made to the mechanically driven piston, the gas pressure generator (131) can be based on:
  • a. An air compressor
  • b. A pressured gas generated by a
    • i. Compressed gas cylinder
    • ii. Cryogenic expansion reaction: water solidification for example.
    • iii. Or preferably, a chemical reaction (like hydrogen peroxide with a catalyst, see list) See FIG. (9).
• 8. In a pressured gas generator (131) based on a chemical reaction; a closed loop is used by the controller (109) to maintain the required system's pressure at a high pressure. The high pressures of hydraulic oil (or isolating gas) reservoirs (155) are controlled by modulating in real-time mechanically (149) and/or electronically (148)(147) the amount of chemical that reacts with the catalyst (132) in the mixing chamber (153). A pump (134) with a check valve at its exit or other may be used to control the flow. From the mixing chamber (153) pistons movement, hydraulic oil (or isolating gas) is pressurized (155) and this simultaneously pressurizes both fluid (120)(121) and chemical (133) reservoirs. Heat generated by the reaction may be used to heat the fluid reservoirs (113), the pump and valve (153) and/or to recharge the batteries (112). After several fired shots, the fluid reservoirs (120)(121) are depleted, the controller (109) depressurizes (122)(154) the mixing chamber (153). Then, the low pressure pumps and valve (153)(152) refill both fluid (120)(121) and chemical (133) reservoirs through check valves (114)(115). To prevent short circuiting the reservoir, through the refilling tube, the remaining fluid in transit is later flushed and expulsed throughout ports (122) by valves (146) and pump & valve (153). The electrolyte is replaced by an isolating flush fluid (150). Finally, the gas pressured gas generator (131) is reset again to working status. The port's (122) external output is in the opposite mean direction of firing jets. This prevents unwanted vibrations. See FIGS. (1, 2, 3 and 9).
• 9. Continuously or alternately when the trigger (116) is pulled half way, the system (109) acquires the target though a range finder (104) or from an external computer that generates a 3D analysis (110) and calculates the required angles for ejector nozzles convergence on the target. See FIGS. (1, 2, 3 and 9).
• 10. The first nozzle may have a fixed position (101). The second of the ejector nozzle (102) has a computer controlled (109) angular position that sets an intersection point at a set distance between the 2 conductive fluid beams. Alternately both nozzles may be actuated. See FIGS. (1, 2, 3 and 9).
• 11. Humidity, temperature and pressure are monitored to calculate the actual dielectric breakdown of air (108&109). The applied voltage is modulated accordingly with the addition target distance measurements See FIGS. (1, 3 and 9).
• 12. Depending on the distance from the target the dispensed volume is calculated by computer (109). Volume controlled is achieved by controlling the pump's (126) or gas pressure generator (131) on-time as the debit is known See FIGS. (1, 3 and 9).
• 13. Alteration of the focal point is modulated based on the computed air dielectric breakdown and the stream's resistivity that result in a constant voltage at the interception point on the target. See FIGS. (1, 3 and 9).
• 14. A high voltage power supply (105&106) is used to apply a potential difference between the two streams of liquid which closes the circuit at the dielectric breakdown point on the target (144). See FIGS. (1, 3 and 9).
• 15. Current & voltage circuits monitor (158) the actual delivered power (137) and adjust the current in real-time (135)(136). Adjustments are conveyed onto the fluid path resulting in the desired effect at the output (144). A redundant secondary control sets the current safety upper limit (138) to a specific setting (minimal, warning, non-lethal shock and lethal shock if allowed by the device power selector (109) and internal configuration). See FIG. (3).
• 16. An enhancement of jet properties can be achieved by viscosity control. This mechanism can use the thermal properties of a special solution, like a gelatin-salt or on a low melting point metal alloy. By keeping the solution inside the device at a significantly higher temperature than the outside; when propelled out from the nozzle, contact with air cools the media and solidifies the solution into a more viscous fluid thus generating longer continuous jet. Both external (140&108) and internal thermal sensors (142) along with an internal heater (143) can be used in a temperature control loop (141) maintaining the required thermal difference. Also, as a possible enhancement, thermo-electric devices (Peltier junction) or other cooling means (139) can be used on the nozzle and on an anterior portion of tubing to rapidly cool the medium. This initiates and possible completes fluid phase changes prior to nozzle exit. See FIG. (3).
• 17. The unit can be portable or stationary. Stationary units may provide larger coverage areas due to faster scanning motors and higher possible jet exit velocities. See FIGS. (2, 10 and 12).
• 18. Multiple simultaneous firing nozzles can be combined for coverage of very large areas.
• 19. Instead of being completely integrated within the device, the three refilling reservoirs (150)(133)(113), pumps & valves (153)(152) and battery pack (112) may be contained in a sole unit named ‘replaceable recharge unit’ (151) that is removable and replaced during action to reduce idle time. Also, large external reservoirs of fluid with a pump are used to refill the device's main reservoirs (113)(150)(133). Furthermore these may be used in some applications (along with permanent tubing) to refill the device continuously allowing uninterrupted operation and/or to lower maintenance. See FIGS. (1, 2 and 9).
• 20. Power is provided onboard with battery packs (112) that optionally can be charged periodically or continually by the charger (111) which may use a fuel cell or thermoelectric generator (TEG) type of generation exploiting the chemical reaction occurring in the gas/fluid pressure generator (131). See FIG. (9).
• 21. The trigger (116) is used to confirm the target (144) and it is protected by a safety lock (117). The shock power level may the controlled by a selector (109). See FIGS. (2 and 3).

Application and Variants

Hand Held Electro Gun Application

The unit can be mounted in a gun like structure as depicted in FIGS. 2A to 2C.

Computerized Raster Electro Wall Application

Multiple units can be assembled in a matrix or fire in a time shared coverage, rendering the effect of an invisible wall. Such an invisible wall or perimeter may be set and can prevent person(s) or animal(s) from penetrating or leaving a quartered off area. This may be used to fence animals or persons from access to an area or passageway.

The thickness of the said raster wall can be altered by creating high speed rastered points in front of one another rendering the perception and sensation of a controlled thickness.

A collection of range measuring sensors as well as cameras may be used to determine target positions. Multiple units can be synchronized together to dispatch proper target coverage and increase wall coverage resolution.

Such units may be mounted on gimbals or pan & scan mechanism to cover larger areas. Alternately beams may be deflected electrically or magnetically.

Portable Variant

Referring to FIG. 10, portable units could be used by riot police to restrict and contain protestors or for crowd control without the use of rubbers bullets or tear gas canisters pepper spray or other firepower. Target identification by visual or a radio frequency ID ensures that law enforcement personnel don't get shocked by the device. For example and without being limitative, FIG. 10 shows the electric projection weapon system being embodied as a crowd control system and being deployed in a hot zone.

Drone Mounted Variant

Referring to FIG. 11, the system may be carried by a drone and used to actively or by remote control shock an enemy or project an invisible cage around a suspect or a dangerous animal who then remains constrained until further intervention can occur. This system has the advantage of having little recoil when fired from a drone. For example and without being limitative, FIG. 11 shows the electric projection weapon system being embodied for containment of an insurgent for later capture using a drone projected invisible cage.

Wall Mounted Surveillance System Variant

Referring to FIG. 12, the unit can be used in conjunction with a surveillance camera with intruder control on private property or high security facilities. This gives the possibility to the surveillance agent to remotely observe a crime in progress. Automatic control can also be used. An identity control such as voice; or facial recognition; or radio identification technology (like RFID) can be used to ensure that is not a false/friendly target. Using an installation which provides standard electric power, network (for camera) along with tubing to an easily accessible large fluid tank, the unit may be operated without the need of access the unit (no ammo or recharging is required). This allows operation as easy as standard surveillance only system and has the benefit of controlling the intruder rather than just seeing him. For example and without being limitative, FIG. 12 shows a wall installation of the unit, therefore adding security to an otherwise vulnerable window.

Explosive or Incendiary Detonated or Ignited at Controlled Distance and Shield Variant

An advanced use of this invention may provide new application fields by using large amount of power (lot more than what is required for human shocking) and using a timely sequenced fired electric bolts at high speed, a moving object can be slowed down or stopped by the action of the electric arcing shockwave result of the focal point A series of lightning bolts of high energy in front of a bullet or missile could destroy it, slow it down enough to significantly reduce damage, create a local shield or induce a trajectory change.

Additionally the device may be fitted with a third nozzle that carries an ignitable or explosive material stream which will be ignited by the electrical spark at the target. The ignitable fluid projection may be stopped and with a computed delay before applying the high voltage generator to the conductive fluid in order to make impossible a back firing. The advantages of using the ignitable material is to increase heat damage of the target; multiple shots; and an easy means of reloading a unit (can be made at ground level).

Extended Possible Mechanisms

• • a) Streams of conductive material and of inflammable material may be liquid solid gaseous or a mixture of both. Powdered metals could even be magnetically projected using rail gun type mechanisms, or using a spark chamber.
  • b) Magnetic or electric fields may be used to coax the ejected jet stream into a well-defined beam of liquid. Electric plates and or magnetic coils may be used to deflect ionized jet onto a trajectory.
  • c) Viscosity control can be based on special conductive polymer streams that turns into gel in air and/or a lower pressure.
  • d) An electromagnetic arc propulsion system could be developed. The weapon can then operate in one of 2 ways either by deflection of a current path compensating an inverted or collapsed magnetic field based on Faradaic principles; or by generating a column of plasma that then serves as a conductive medium for a second HV source based on Lorentz force law and electric propulsion.
    • Principally 2 electro-magnetic interactions are at play one is Lenz's law; and the other is the Lorentz force in the presence of orthogonal components of magnetic field and current. (Refer to addendum for additional information).
  • e) Finally an ionization system in which at least one pair of pulsed radiation (normally lasers) rays combine to join energy at a series of targets arranged in a stream by rapid firing. The lasers have a frequency that matches the spectrum absorption band of one the major atmospheric gas (O₂, N₂ or Ar) and/or have the 1^st level direct ionization frequency of such gas. The converged radiation is absorbed as heat or ionization in a stream of air. This creates a lower impedance path for electric arcs. This path can be made directly or increased progressively to angle in a succession of rapid events reaching the target. The arcing beam trajectory that may be modulated along a path in 3-D, which can be curved or straight. FIG. 13 shows possible modifications of the system, using a radiation source to ionize air in the path of firing in a sequence of burst that can be directed 3 dimensionally by the meeting of combined energy pulses. A rapid firing of these heated coordinated may trace a trajectory for the electric path. The trajectory may even be curved.

Angle Determination and Target Acquisition

The computed angle can be worked out to the difference between 90 degrees and the inverse tangent of the ratio of distance between the 2 beams and target distance. The dielectric breakdown component can be accounted for by projecting the breakdown distance with the same angular ration and subtracting that from the distance.

FIG. 14 shows a geometry for target meeting of converging beams. In FIG. 14 “d” is the distance between the two firing jets “D” the intersection distance to the target, “α” is the angle between to joining beams and “θ” the computer controlled angle for firing. Where δ is the dielectric breakdown distance and Δ is the distance correction to the target. Then it can be easily derived that θ is:

${\theta }_o=90°-\left[{\tan }^{-1}\left(\frac{d}{D}\right)\right]$

Then we note that the practical measured distance to the target is actually 1 and not D where 1=D−Δ.

We also know that Δ/δ=D/d Thus:

$\Delta =\frac{\delta }{\tan \left(90-\theta \right)}\mathrm{Therefore},\theta =90-{\tan }^{-1}\left[\frac{\delta }{\text{?}+\left(\frac{\delta }{\tan \left(90-\theta \right)}\right)}\right]$ $\text{?}\text{indicates text missing or illegible when filed}$

From the above equation θ can be discovered numerically by iteration plugging θ₀. As a first approximation. 3 or 4 polynomial McLaurin approximations can be worked out for trigonometric estimation that are accurate enough for precise angle stepping. As distance increase is becomes more important to improve finesse in step control of the jet defecting mechanism.

The depth of the firing is computed based on the position of the target such that a arching distance occurs on the target in this case breakdown is computed from the ratio of D/d

Magnetic arc Propulsion Mechanisms

Consider the following setup of a classic rolling bar experiment in physics. In this paradigm however, the rolling bar is replaced with an electric arc. This arc may be further seeded with ionic solutions, solids or gases creating a plasma.

Referring to FIG. 15, an embodiment where the rolling bar is replaced by an electric arc is shown. Hence, the ions in the arc plasma can be propelled according to the generated force. In this case the metallic conductor can be substituted with a plasma that is propelled by a high energy magnetic pulse, making use of Lorentz's force law and a constant current HV source. In effect there is therefore a MHD propelled arc. In the diagram of FIG. 15, L is the current arc path length, I is the current B creating the magnetic field and F the resulting force acting on ionic entities.

As current flows in the corona arc; the generated plasma will be subject to the Lorentz force as described below and the electrons or plasma are propelled according to the Lorentz force equations which is:

$F_L=n·q·\underset{\text{?}}{\to }x\underset{B}{\to }\text{?}\text{indicates text missing or illegible when filed}$

Which can be expressed in terms of the plasma current and arc path length as:

$F_L=I_p\underset{L}{\to }x\underset{B}{\to }$

Where Ip is the plasma current, L is the current path length vector and B would be the magnetic field vector produced by an electromagnet. In such a case then, from Ampere's law the magnetic field of the electromagnet can be worked out to be:

$\underset{B}{\to }=p_o·p_r·N·I_M$

Where I_m is the current through the electromagnet plugging back then we have:

$a_e=\frac{\left(\text{?}·I_P\right)x\left({\mu }_o·{\mu }_r·N·I_M\right)}{\text{?}}$ $\text{?}\text{indicates text missing or illegible when filed}$

Where Ip is:

$I_p=I_{\mathrm{source}}-I_{\mathrm{ind}}$

For computing current special case we are interested in is based on the empirical observations known as Lenz's law (Heinrick Lenz 1834). This a special case of Faradays eauation Lenz's states that:

${\varepsilon }_{\mathrm{ind}}=-\frac{d\text{?}}{\mathrm{dt}}=-B·L·\text{?}\mathrm{And}\mathrm{thus}I_{\mathrm{ind}}=\frac{-B·L·\text{?}}{\text{?}}$ $\text{?}\text{indicates text missing or illegible when filed}$

By substituting in the above we then have that

$a_e=\frac{\left(\text{?}·\left\{I_{\mathrm{source}}\frac{-B·L·\text{?}}{R}\right\}\right)x\left({\mu }_o·{\mu }_r·N·I_M\right)}{\text{?}}$ $\text{?}\text{indicates text missing or illegible when filed}$

By rearranging the terms and expressing acceleration and velocity in terms of displacement is possible to show that:

$\text{?}·\frac{d^2x}{{\mathrm{dt}}^2}+L·{\left({\mu }_o·{\mu }_r·N·I_M\right)}^2·\frac{\mathrm{dx}}{\mathrm{dt}}-L·I_{\mathrm{source}}=0$ $\text{?}\text{indicates text missing or illegible when filed}$

Which is a second order homogeneous differential equation. The systems can then be tune for overdamped, damped or underdamped response. Note that ionic collision dynamics should be used to further refine this model. As an approximation very large accelerations can be present. The system is in essence an MHD plasma propulsion in which the plasma also carries (charge) electricity

By modulating the magnetic field in the above setup; it would be possible to project an ionic stream in the forward direction. This stream can then either deflect the current path L through the air or be utilized in pairs of ionized plasma channels that then provide a low impedance path for electric arcing. Ionic columns can be formed in this way and then paired can be used to join at a target point and serve as a path for yet another high voltage supply electrifying the so defined path.
