Abstract

A system for selectively disabling a vehicle. In the illustrative embodiment, the system adapted to prevent high-speed automotive chases. The system includes a first mechanism for locating vehicle to be disabled. A second mechanism launches a disabling projectile toward the vehicle. A third mechanism employs the projectile to disable the vehicle by suffocating an engine of the vehicle or otherwise compromising the fuel/air mixture. In a specific embodiment, and an infrared guidance system guides the projectile toward a muffler of the vehicle, and a muffler-plugging agent incorporated within the projectile plugs a muffler.

Claims

1. A system for selectively disabling a vehicle comprising:

first means for locating a vehicle to be disabled;

second means for launching a disabling projectile toward said vehicle; and

third means for suffocating an engine of said vehicle via said projectile, thereby disabling said vehicle.

2. The system of claim 1 wherein said third means includes fourth means for plugging a muffler of said vehicle, said fourth means including a muffler-plugging agent incorporated within said projectile.

3. The system of claim 2 wherein said system further includes fifth means for guiding said projectile toward said muffler.

4. The system of claim 3 wherein said fifth means includes an infrared guidance system.

5. The system of claim 1 wherein said third means includes a gas incorporated within said projectile, said gas sufficient to stall said vehicle upon or after entering an engine of said vehicle.

6. The system of claim 5 wherein said system further includes sixth means for selectively dispersing said gas upon or after impact of said projectile with said vehicle.

7. The system of claim 6 wherein said projectile includes a sticky substance for adhering said projectile to said vehicle.

8. The system of claim 7 wherein said system further includes seventh means for directing said projectile into an aperture of said muffler, thereby at least partially plugging said muffler.

9. A device for disabling a vehicle comprising:

a muffler-clogging agent and

means for selectively activating said muffler-clogging agent to effect clogging of a muffler of said vehicle in response to a predetermined condition.

10. The system of claim 9 further including means for directing said device toward said target.

11. The system of claim 10 wherein said means for directing includes a targeting and guidance system employing infrared energy emanating from said muffler, and wherein said system further includes a controller in communication with said targeting and guidance system for providing control signals to control steering actuators positioned on or within said device.

12. The system of claim 11 wherein said means for selectively activating includes a fuze.

13. The system of claim 12 wherein said fuze is a Micro Electromechanical Systems (MEMS) fuze that is armed upon launch of said projectile and activated upon impact of said projectile with said muffler.

14. The system of claim 13 wherein said fuze is a remote-controlled fuze responsive to a signal from said controller.

15. The system of claim 10 wherein said muffler-clogging agent includes plural muffler-clogging beads capable of expanding upon entering an aperture of said muffler, thereby clogging said muffler, whereby said vehicle is slowed or disabled.

16. The system of claim 10 wherein said muffler-clogging agent includes hardening glue or a sticky gelatinous material.

17. A system for selectively disabling a vehicle comprising:

first means for determining the location of a muffler of said vehicle;

second means for launching a projectile toward said muffler; and

third means for clogging said muffler via said projectile.

18. The system of claim 17 further including fourth means for guiding said projectile to said muffler based on the location of said muffler as determine by said first means.

19. The system of claim 18 wherein said first means includes an infrared seeker installed on said projectile, said infrared seeker capable of tracking the location of said muffler, particularly an aperture of said muffler, based on heat emanating from said muffler, and wherein said fourth means includes fifth means for controlling the trajectory of said projectile via one or more steering actuators positioned on said projectile, said fifth means responsive to control signals based on output from said infrared seeker.

20. The system of claim 18 wherein said first means includes a target tracking system remotely positioned relative to said projectile, said target tracking system capable of tracking the location of said muffler and providing a signal in response thereto.

21. The system of claim 20 wherein said fourth means further includes means for receiving said signal, said means for receiving said signal positioned on said projectile and capable of controlling the direction of flight of said projectile based on said signal.

22. The system of claim 21 wherein said first means includes an infrared imaging system for receiving infrared energy from a scene containing said muffler and providing an infrared image in response thereto to said tracking system.

23. The system of claim 22 wherein said first means includes a ladar or radar system for providing additional image information pertaining to said scene, said additional image information including distance information, and further including sixth means for employing said distance information to selectively activate said projectile.

24. The system of claim 18 wherein said fourth means includes a boresight guidance system that includes an imaging system in communication with a controller, said controller forwarding guidance signals to a receiver on said projectile for controlling actuators on said projectile to steer said projectile toward a boresight of said imaging system, said boresight approximately aligned with said muffler.

25. The system of claim 18 wherein said third means includes a muffler-clogging agent on or within said projectile that includes plural beads, said beads including means for expanding upon lodging within said muffler, thereby sufficiently restricting exhaust flow from said muffler to cause said vehicle lose power and/or stall.

26. The system of claim 25 wherein said plural beads each include a fuze in communication with a container containing pressurized gas and surrounded by a material that expands upon release of said pressurized gas in response to activation by said fuze.

27. The system of claim 26 wherein said fuze is impact-sensitive, temperature-sensitive, or responsive to remote activation signals.

28. The system of claim 25 wherein said third means includes a fuze in communication with a charge, said charge sufficient to disperse said muffler-clogging agent from said projectile in response to activation by said fuze.

29. The system of claim 28 wherein said muffler-clogging agent includes foam or sponge material and/or a substance that hardens in response to heat from said muffler and/or said charge.
