20080295677 | Method and apparatus for detecting and disabling optical weapon sight - The present invention is an apparatus for detecting and disabling a human eye or optical device used in the fire control of a weapon. This apparatus comprises a prism having a plurality of peripheral reflective surface. This prism has a longitudinal axis and rotating about said longitudinal axis. An infrared (IR) laser directs an infrared laser beam toward the prism side that the laser beam is reflected toward the human eye or optical device, such that the IR laser beam is retroreflected to the prism. There is also an infrared IR detector which detects the IR retroreflected laser beam reflected from the prism. A visible light wavelength laser which produces a visible light wavelength laser beam which is reflected from the prism to the human eye or optical device to disable the human eye or optical device to prevent use of the weapon. | 12-04-2008 |

Subterranean-to-terrestrial communication is established by a low-frequency handheld transmitter using repeat processing to transmit digital data from the subterranean location to the surface of the earth using modulated H-field waves. | 06-11-2009 |
20090308970 | POD launched unmanned air vehicle - A method for attacking dispersed targets from a single aircraft standing off at a significant distance from the target area, wherein pods of individually targeted UAVs are carried in lieu of a bomb on a conventional bomb rack. | 12-17-2009 |
20100231389 | METHOD AND APPARATUS FOR TRACKING AND LOCATING EXPLOSIVES AND EXPLOSIVE MATERIALS WORLDWIDE USING MICRO RF TRANSPONDERS - Stolen or lost explosives are detected by fixing micro RF transmitters in the form of RFID tags to the explosive packaging or embedding them in the explosive material itself. Moreover, the subject microradio transponders may be contained in an adhesive binder or slurry. The identity of the explosive, its place of manufacture and ownership is detectable by RFID tag interrogators strategically located along commonly used roads or railways in which the RFID tags scavenge energy from interrogation beams, with the RFID tags indicating the identity of the explosive and its origin. | 09-16-2010 |
20110187363 | METHOD AND APPARATUS FOR SENSING THE PRESENCE OF EXPLOSIVES, CONTRABAND AND OTHER MOLECULES USING NUCLEAR QUADRUPOLE RESONANCE - Stimulated emissions due to nuclear quadropole resonance are detected utilizing a terminated balanced transmission line and a directional coupler for the detection of explosives, contraband, narcotics and the like that exist between the transmission lines, with either a stepped frequency generator utilized to scan between 100 KHz and 10 MHz, or wherein parallel fixed frequency sources are coupled to the transmission line, thereby to permit correlation with expected lines, with the frequency sources being low power so as to not create a safety hazard and so as not to interfere with radiation sensitive devices such as film or electronic circuits that are in the vicinity of the balanced transmission line. | 08-04-2011 |
20110283877 | METHOD OF PROVIDING A DEFENSE AGAINST A SHAPED CHARGE - A method of providing a defense against a shaped charge uses an outer and an inner armor layer provided with a medial space between these outer and inner armor layers. One or more defensive shaped charges are positioned in the medial space. If the outer armor layer is attacked by ordnance having an offensive shaped charge, one or more of the defensive shaped charges positioned in the medial space is detonated so as to degrade the effectiveness of the offensive shaped charge and prevent penetration of the inner armor layer. | 11-24-2011 |
