Abstract

A modulation device for directing a mobile tracking device away from an asset is provided. The modulation device includes a continuous wave laser source whose output is directed at a seeker head of the mobile tracking device. The modulation device causes the generation of localized sources within the mobile tracking device and confuses the mobile tracking device as to the true location of the asset. A portable cutting device is disclosed. The portable cutting device may include a portable power supply and a laser source. The portable power supply and laser source of the portable cutting device may be positioned within a backpack and carried by a user. A handheld unit which is coupled to the laser source may be supported by the hands of the operator. The handheld unit provides power generated by the laser source to a barrier to be cut.

First claim

The invention claimed is:

1. An apparatus for interacting with a mobile tracking device, the apparatus comprising:
a body;
at least one propulsion device supported by the body;
a plurality of sensor modules supported by the body which monitor the environment surrounding the body;
a controller operatively connected to the plurality of sensor modules, the controller determining a presence of the mobile tracking device in the environment surrounding the body based on information collected by the plurality of sensor modules and a current location of the mobile tracking device comprising a type of mobile tracking device which is identified based on a retro-reflection received from mobile tracking device;
a modulation system which receives the current location of the mobile tracking device from the controller, orients a tracking system of the modulation system based on the current location of the mobile tracking device, detects the mobile tracking device, updates the location of the mobile tracking device, and directs a continuous beam of optical energy at the mobile tracking device, the continuous beam of optical energy being produced by a plurality of semiconductor lasers whose output are combined, wherein said beam is directed towards and is received by a telescope within said mobile tracking device, wherein said beam is configured to produce different effects on said mobile tracking device receiving said optical energy based on a separation distance of said mobile tracking device from the modulation device, wherein said separation comprises distance that is divided into three ranges comprising a near distance band, a mid-distance band, and a far distance band, wherein at distances in near distance band energy of said beam explodes seeker head and destroys mobile tracking device, at distances in mid distance band the beam destroys functionality of detector, wherein distances in said far distance band the beam produces a plurality of internal localized infrared radiation sources within said mobile tracking device, said internal localized sources are produced by the beam being absorbed by optical components of mobile tracking device which then reradiate absorbed energy in multiple wavelengths within the mobile tracking device, wherein the beam produces infrared energy which is brighter than infrared signature of an asset initially being tracked by said mobile tracking device such that a controller of said mobile tracking device interprets reradiated absorbed energy within the mobile tracking device as the infrared signature of the asset, wherein if internal reradiated energy is off-axis of the infrared signature of said asset, controller will generate an erroneous guidance signal that causes said mobile tracking device to alter the mobile tracking device's path of travel away from said asset.

2. The apparatus of claim 1 , wherein the plurality of semiconductor lasers are quantum cascade lasers.

3. The apparatus of claim 1 , wherein the output of each of the plurality of semiconductor lasers are incoherently combined to produce the continuous beam of optical energy.

4. The apparatus of claim 1 , wherein the controller continues to update the current location of the mobile tracking device until the modulation system detects the mobile tracking device, the modulation system using the updated current location to orient the tracking system.

5. The apparatus of claim 4 , wherein the plurality of sensor modules have a wide field of view to survey the environment around the body and the modulation system has a narrower field of view to focus on the location of the mobile tracking device.

6. The apparatus of claim 1 , wherein the modulation system includes a beam control module which controls a direction of the continuous beam of optical energy based on the updated location of the mobile tracking device.

7. The apparatus of claim 6 , wherein the continuous beam of optical energy is provided until the beam control module has caused the direction of the continuous beam of optical energy to move by a predetermined threshold amount.

8. The apparatus of claim 7 , wherein the predetermined threshold amount is three degrees.

9. The apparatus of claim 2 , wherein the modulation system includes a beam control module which controls a direction of the continuous beam of optical energy based on the updated location of the mobile tracking device, the beam control module being coupled to said semiconductor lasers comprising a continuous wave fiber laser through an optical conduit.

10. The apparatus of claim 9 , wherein the modulation system includes a housing and beam control module includes a positioning system which includes a rotatable head coupled to the housing and including an optical window through which the continuous beam of optical energy exits counter measure system, the positioning system rotating the rotatable head to control the direction of the continuous beam of optical energy.

11. The apparatus of claim 10 , wherein the positioning system further includes a moveable optical component which may be moved to control the direction of the continuous beam of optical energy.

12. An apparatus for use with an asset and for interacting with a mobile tracking device, the apparatus comprising:
a pod configured to be attached to the asset, the pod including an optical window;
a plurality of continuous wave semiconductor lasers positioned within the pod;
a controller positioned within the pod operatively connected to the plurality of sensor modules, the controller determining a presence of the mobile tracking device in the environment surrounding the body based on information collected by the plurality of sensor modules and a current location of the mobile tracking device;
a modulation and beam directing system positioned within the pod which receives the current location of the mobile tracking device from the controller, orients a tracking system of the modulation system based on the current location of the mobile tracking device, detects the mobile tracking device, updates the location of the mobile tracking device, and directs a continuous beam of optical energy produced from said continuous wave lasers at the mobile tracking device, the continuous beam of optical energy being produced by a plurality of semiconductor lasers whose output are combined; and
a battery source operatively coupled to the plurality of continuous wave semiconductor lasers and positioned within the pod, the battery source providing power to the plurality of continuous wave semiconductor lasers to produce a continuous beam of optical energy;
wherein said beam is directed towards and is received by a telescope within said mobile tracking device, wherein said beam is configured to produce different effects on said mobile tracking device receiving said optical energy based on a separation distance of said mobile tracking device from the modulation device, wherein said separation comprises distance that is divided into three ranges comprising a near distance band, a mid-distance band, and a far distance band, wherein at distances in near distance band energy of said beam explodes seeker head and destroys mobile tracking device, at distances in mid distance band the beam destroys functionality of detector, wherein distances in said far distance band the beam produces a plurality of internal localized infrared radiation sources within said mobile tracking device, said internal localized sources are produced by the beam being absorbed by optical components of mobile tracking device which then reradiate absorbed energy in multiple wavelengths within the mobile tracking device, wherein the beam produces infrared energy which is brighter than inf
