Abstract
Description
- This application is related to U.S. patent application Ser. No. [Goldman 28], titled “Forced Premature Detonation of Improvised Explosive Devices via Radiated Electromagnetic Energy,” Ser. No. [Goldman 29], titled “Forced Premature Detonation of Improvised Explosive Devices via Heavy Vibration,” Ser. No. [Goldman 30], titled “Forced Premature Detonation of Improvised Explosive Devices via Laser Energy” and Ser. No. [Goldman 33], titled “Forced Premature Detonation of Improvised Explosive Devices via Noise Print Simulation,” each filed concurrently with the present application and assigned to the assignee of the present invention.
- This invention relates generally to counter-terrorism methods and devices and, more particularly, to methods and devices for triggering premature detonation of Improvised Explosive Devices (IEDs) utilizing chemical substances.
- An Improvised Explosive Device (IED) is an explosive device that is cobbled together (or “improvised”) for example, from commercial or military explosives, homemade explosives, military ordnance and/or ordnance components, typically by terrorists, guerrillas or commando forces for use in unconventional warfare. IEDs may be implemented for the purpose of causing death or injury to civilian or military personnel, to destroy or incapacitate structural targets or simply to harass or distract an opponent. IEDs may comprise conventional high-explosive charges alone or in combination with toxic chemicals, biological agents or nuclear material. IEDs may be physically placed at or near a pre-determined target or carried by person or vehicle toward a predetermined target or target of opportunity.
- As will be appreciated, the design of construction of an IED and the manner and tactics for which a terrorist may employ an IED may vary depending on the available materials and sophistication of the designer. As such, a variety of different triggering mechanisms could be used to trigger detonation of IEDs. It is contemplated that certain IEDs, either by design or by nature of the triggering mechanism, may detonate responsive to chemical substances of a certain type or characteristic. For example and without limitation, exhaust fumes from a vehicle can yield chemical particles that may trigger detonation of IEDs. It is a concern that this tactic can be used to trigger bombings against civilian and military targets throughout the world. Accordingly, there is a need for precautionary measures to respond to this threat.
- The present invention provides systems and methods for guarding against chemical substance-triggered IEDs by forcing premature detonation of the IED at a safe distance from a prospective target, thereby reducing the effectiveness of the IED. Embodiments of the invention provide for releasing chemical substances from a stationary or mobile platform (hereinafter “Chemical Platform (CP)) to a stationary or mobile area defining an “IED detonation zone.” IEDs within the IED detonation zone that are triggered by chemical substances will receive the radiated chemical substances, thereby forcing premature detonation of IEDs in the detonation zone.
- The foregoing and other advantages of the invention will become apparent upon reading the following detailed description and upon reference to the drawings in which:
-
FIG. 1 is a block diagram of an IED defense system including one or more Chemical Platforms (CPs) according to embodiments of the invention; -
FIG. 2 illustrates a manner of deploying CPs about a stationary target area defining a stationary IED detonation zone; -
FIG. 3 illustrates a manner of deploying CPs about a mobile target area defining a mobile IED detonation zone; and -
FIG. 4 is a flowchart of a method for implementing an IED defense system using mobile or stationary CPs to force premature detonation of IEDs within an IED detonation zone. -
FIG. 1 shows by way of example and not limitation, anIED defense system 100 for guarding against chemical substance-triggered IEDs. A system controller 102 controls and coordinates operation of one or more Chemical Platforms 104 (CP1 . . . CPn). TheCPs 104 operate responsive to activation by the system controller to project plumes 106 (P1 . . . Pn) comprising one or more chemical substances within anIED detonation zone 108. - The
system controller 102 includes aprocessor 112 andmemory 114 for controlling the operation of CPs within theIED defense system 100. In one embodiment, the processor executes software routines for managing operation of the various CPs, including, for example and not limitation, activating and de-activating the CPs and controlling the type(s) and amount of chemical substances to be released. The memory stores software routines for controlling the CPs and information relating to the identity, characteristics and location of the various CPs in the IED defense system. Alternatively or additionally, the system controller may 102 operate responsive to manual input from a human operator (not shown). As will be appreciated, thesystem controller 102 is a functional element that may reside in a single device or may be distributed among multiple devices and multiple locations. For example and without limitation, the system controller functionality may reside in a centralized platform; or controller functionality may reside in individual CPs to allow for independent operation of the CPs. - As shown, the system controller includes a
transceiver 116 for communicating with theCPs 104 viawireless resources 118. TheCPs 104 similarly includetransceivers 116 for communicating with the system controller, or with each other, viawireless resources 118. As will be appreciated, the wireless transceivers may be eliminated, for example, in embodiments where controller functionality resides within the CP. Thewireless resources 118, where applicable, may comprise narrowband frequency modulated channels, wideband modulated signals, broadband modulated signals, time division modulated slots, carrier frequencies, frequency pairs or generally any medium for communicating information to or from the CPs. The wireless resources may implement air interface technologies including but not limited to, CDMA, TDMA, GSM, UMTS or IEEE 802.11. - The
CPs 104 executecontrol logic 120 responsive to instructions from the system controller 102 (or where applicable, from their own resident controllers) to activaterespective drivers 122 for activatingchemical sources 124. Responsive to the control logic and drivers, the chemical sources release one or more chemicals defining respective plumes 106 (P1 . . . Pn) within theIED detonation zone 108. As will be appreciated, the nature and type of the chemical sources may be selected or combined to produce one or more characteristic type(s) of chemical plumes that are believed to trigger detonation of IEDs. In one embodiment, the CPs are implemented to produce a chemical plume having a particular signature characteristic of a prospective target. For example and without limitation, the CPs may be implemented to simulate the exhaust fumes produced by a diesel truck. Generally, it is contemplated that virtually any type of chemical substances may be released and at varying volumes, temperatures, release sequences or the like to produce a desired characteristic plume. Further, the physical location and/or direction of the sources may be varied, individually or collectively. - As shown, a
fan 128 andheater 130 are provided for the purposes of cooling and heating thechemical sources 124, respectively, as may be needed to realize a desired temperature or regulate the temperature of thechemical sources 124. Agauge 132 measures and displays one or more parameters of the chemical substances. As will be appreciated, multiple gauges or multi-purpose gauges may be used to measure a plurality of parameters of the chemical substances. The parameters may include, for example and without limitation, the temperature of the chemical substance or the amount (e.g., volume) of chemical substance remaining. In one embodiment, thefan 128 andheater 130 are operated under control of thecontrol logic 120 and/or thesystem controller 102, such that operation of thefan 128 andheater 130 may be implemented by software routines executed within thecontrol logic 120 and/or thesystem controller 102. Thegauge 132 is operably connected to thecontrol logic 120 and/orsystem controller 102 to allow for monitoring and adjustment of one or more parameters as may be required, by thecontrol logic 120 and/orsystem controller 102. - A directional nozzle 132 (or optionally, nozzles) allows for spraying or directing the released chemical substances in a desired direction or multiple simultaneous directions. As will be appreciated, the nozzle(s) 132 may be implemented in a variety of forms, for example, to release chemical substances at a desired pressure or to achieve a desired spray pattern or characteristic.
- As will be described in greater detail in relation to
FIG. 2 andFIG. 3 , the CPs may be deployed on mobile or stationary platforms, or some combination thereof, to effect a mobile or stationaryIED detonation zone 108. In either case, the IED detonation zone is advantageously positioned a safe distance from civilian or military personnel or structural targets, such that detonation of IEDs in the zone will not cause significant damage to persons or property. Detonation of IEDs within the zone is referred to as a forced premature detonation since it is instigated by theIED defense system 100 and will occur before intended by the person or agency deploying the IED. -
FIG. 2 illustrates a manner of deploying CPs about a stationary target area defining a stationary IED detonation zone. For convenience, similar reference numerals will be used to describe like elements inFIG. 1 andFIG. 2 , albeit with “200” series reference numerals inFIG. 2 rather than “100” series. For example, the IED detonation zone, referred to byreference numeral 108 inFIG. 1 will be referred to byreference numeral 208 inFIG. 2 . - In the embodiment of
FIG. 2 , a stationaryIED detonation zone 208 is defined by deploying one ormore CPs 204 at predetermined fixed positions about a designated geographic area in which premature detonation of IEDs is desired. The designated geographic area may comprise, for example, a remote checkpoint or staging area situated a safe distance (e.g., 500 ft.) from persons or structures that may be targeted by IEDs. When activated, theCPs 204 release chemical substances within the IED detonation zone, substantially as described in relation toFIG. 1 , so as to force premature detonation of IEDs within or entering thezone 108. The CPs may be activated responsive to a system controller (not shown inFIG. 2 ) or a human operator. - As shown,
vehicle 230 is traveling on a transportation path 232 (e.g., a roadway) toward a prospective target or target area.Vehicle 230 is carrying an IED that may be triggered to detonate by chemical substances. As the vehicle proceeds alongpath 232, it encounters and enters the stationaryIED detonation zone 208. Generally, when a person or vehicle first approaches the IED detonation zone, it is not known to be carrying an IED and even if an IED is detected, the type of triggering device may not be known. Accordingly, any unidentified person or vehicle entering the IED detonation zone will at least initially be perceived as a threat. Consequently, in one embodiment, the person or vehicle is stopped upon entering the IED detonation zone. Optionally, agate 234 is utilized to facilitate stopping the person or vehicle. While the person or vehicle is stopped, or generally at any time while the person or vehicle is within thedetonation zone 208, theCPs 204 may be activated to release chemical substances within the zone. In such manner, any IEDs carried by the person or vehicle that are triggered by chemical substances are prematurely detonated within thezone 208. An alternative implementation is that the zone is sufficiently wide that the person or vehicle does not need to be impeded by a gate, but will be in the zone for sufficiently long enough time as to allow the chemical substances to cause premature detonation of the IED. -
FIG. 3 illustrates a manner of deploying CPs about a mobile target area defining a mobile IED detonation zone. For convenience, similar reference numerals will be used to describe like elements inFIG. 1 andFIG. 3 , albeit with “300” series reference numerals inFIG. 3 . For example, the ED detonation zone, referred to byreference numeral 108 inFIG. 1 will be referred to byreference numeral 308 inFIG. 3 . - In the embodiment of
FIG. 3 , one ormore CPs 304 are deployed onvehicles 330 traversing a transportation path (e.g., roadway) 332. In one implementation, thevehicles 330 comprise drone vehicles traveling in advance of a convoy of troops. At various points along thetransportation path 332, thevehicles 330 may encounter IEDs that are possibly triggered by chemical substances. TheCPs 304, when activated, produce a mobileIED detonation zone 308 that advances along thetransportation path 332 along with the mobile platform. The CPs may be activated responsive to a system controller (not shown inFIG. 3 ) or a human operator. TheIED detonation zone 308 comprises chemical substance plumes substantially as described in relation toFIG. 1 . As such, any IEDs on the transportation path that are encountered by the advancingIED detonation zone 308 are likely to become prematurely detonated if they are triggered by chemical substances. - Now turning to
FIG. 5 , there is shown a flowchart for implementing an IED defense system using mobile or stationary CPs. Atstep 402, an authority or agency responsible for implementing an IED defense system defines an IED detonation zone. The IED detonation zone may define a stationary detonation zone such as described in relation toFIG. 2 or a mobile detonation zone traversing a transportation path such as described in relation toFIG. 3 . As will be appreciated, multiple IED detonation zones may be defined to cover multiple geographic areas or transportation paths as needed or desired. - At
step 404, the responsible authority or agency deploys one or more CPs as necessary to obtain desired chemical coverage within the zone. For example, in the case where the IED detonation zone defines a stationary zone, one or more CPs may be deployed at one or more predetermined locations residing within or proximate to the stationary zone as necessary to obtain desired chemical substance coverage within the zone; or in the case where the IED detonation zone defines a mobile zone, one or more CPs may be deployed on drones or other suitable transport vehicles adapted to traverse a designated transportation path. - As has been noted in relation to
FIG. 1 , the nature and type of the CPs may be selected to produce one or more characteristic type(s) of chemical substance plume(s) that are believed to trigger detonation of IEDs. In one embodiment, the chemical plume simulates the exhaust fumes of a diesel truck. - Sometime after the CPs are deployed, the CPs are activated at
step 408 to release chemical substances within the zone. Depending on implementation, the CPs may be operated alone or in combination and at varying volumes, release sequences or the like to produce a desired characteristic chemical plume or plumes. - At
step 410, IED(s) within the designated stationary or mobile zone come into contact with the chemical plumes, causing the IED(s) to prematurely detonate if they include triggering mechanisms that respond to chemical substances. - Optionally, at
step 412, the responsible authority or agency may choose to reconfigure one or more CP(s) to obtain different coverage or define a different IED detonation zone. If reconfiguration is desired, reconfiguration is accomplished atstep 414. It is contemplated that reconfiguration may be accomplished while the CP(s) remain active or after they are de-activated. At some point when it is desired to cease releasing chemicals within the IED detonation zone, the CPs are de-activated atstep 416. - In one embodiment, activation or de-activation of the CPs at
steps system controller 102. As has been noted, the system controller functionality may reside in a centralized platform; or controller functionality may reside in individual CPs to allow for independent operation of the CPs. Alternatively or additionally, one or more CPs may be activated or de-activated responsive to human control. Generally, instructions for activating and operating the CPs or de-activating the CPs may be implemented on any computer-readable signal-bearing media residing within the system controller or residing in individual CPs. The computer-readable signal-bearing media may comprise, for example and without limitation, floppy disks, magnetic tapes, CD-ROMs, DVD-ROMs, hard disk drives or electronic memory. The computer-readable signal-bearing media store software, firmware and/or assembly language for performing one or more functions relating tosteps - The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. For example, the CPs may be deployed with or without a
system controller 102; and the CPs may be implemented alone or in combination to release chemical substances of various types and/or characteristics that may differ from the described embodiments. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
