A device operative to detect metal objects. The device includes a transmitter circuit, an upper transmitter coil and a lower transmitter coil operatively connected to the transmitter circuit. A current fed through the upper transmitter coil and the lower transmitter coil generates a field that excites eddy currents in metal objects in the vicinity of the upper transmitter coil and the lower transmitter coil. An upper magnetic field detector and a lower magnetic field detector are operative to sense eddy currents generated in the metal objects. Processor elements operatively connected to the upper magnetic field detector and the lower magnetic field detector collect, store and analyze the eddy currents and thereby determine the likelihood that a metal object has been detected. A navigation system operatively connected to the processor elements controls movement of the device. Transporting elements operatively connected to the navigation system are operative to support the device and permit alteration of a position of the device.

A Kinetic Energy penetrator round is shown effective in neutralizing incoming air borne threat munitions such as rockets, artillery, or mortars for instance, without posing a threat in urban environments to harm bystanders on the ground. There are also no hazards or expense with this round of cleaning up unexploded ordnance, which might have occurred with other types of rounds due to unreliability of self destruct mechanisms. Shown herein is a kinetic energy penetrator for air defense that merely self destructs beyond its operational range into fragments that are not lethal to personnel on ground; no pyrotechnic or energetic materials means are used to activate this self destruct process. A full bore projectile structure is shown that is composed of plural axi-symmetric circular disks stacked on each other and tied by a shape memory metal wire of Nitinol. While operational as a joined group, the disks are a formidable round to kill an incoming air target. After the self destruct phase however, each disk is separated from adjacent disks on either side by a spring mechanism that enables separation after the process is initiated in flight when the Nitinol wire deforms due to heating from air drag. Each disk then proceeds alone with low enough terminal kinetic energy on the ground to be less than lethal.

A method for neutralization of the explosive content of mines and UXO by essentially completely consuming the explosive by combustion or decomposition before any explosion occurs. A charge of a compound that reacts with an extremely high heat-release rate is ignited on or near the casing of the device to be neutralized. The intense exothermic reaction generates high temperature combustion products that will disrupt the casing, thus leading to combustion or decomposition of the explosive. The holes melted in the mine casing enable ignition of a large area of the explosive charge and provide easy access for atmospheric air to support active burnout of the explosive.The apparatus comprises the compound that reacts with a high heat release rate, an ignition source, and a container for the assembly.

This invention generally relates to a method and apparatus to neutralize ordnance, more specifically improvised explosive devices (IEDs) and unexploded ordnance (UXOs). The current invention provides a simple method to neutralize the ordnance by taking advantage of a new class of energetic materials that includes nano-thermites, binary thermites and additionally powdered thermites. In the invention, a projectile is loaded with the new class of energetic materials and fired into the ordnance. The impact causes the energetic materials to react in such a fashion that the explosive compound or other material within the IED or UXO is burned in a self-propagating mode without exploding. Hence, the ordnance is neutralized.

To fully characterize the inductive response of an isolated conductive object, such as buried unexploded ordinance, one needs to measure its response to stimulation by primary magnetic fields in three linearly independent (e.g., approximately orthogonal) directions. In one embodiment this is achieved by measuring the response to magnetic fields of three independent transmitters arranged to have magnetic fields that are linearly independent. According to the apparatus and methods employing the system of this invention, multiple transmitters and receivers of known relative position and orientation on a single platform are used. In a preferred embodiment, matched sets of receiver pairs connected in gradient mode are positioned adjacent to closely spaced pairs of transmitting coils, such that a minor displacement of one or both of the receiver coil pairs relative to the paired transmitting coils will not affect the detected secondary signals emitted by a buried metallic object.

A KE rod warhead for artillery rockets contains a multiplicity of KE rod penetrators housed in trays and packaged into bays or tier packs that are stacked and positioned around a center column of the warhead. The warhead has a skin which is severed upon the rocket entering a target area. The KE rods are situated and housed in such a manner that upon release the rods experience a minimum of pitching or tumbling upon entering the air stream giving the rods an optimal lethality against a designated target. The KE rod artillery rocket contains no explosive munitions, so it can be used without civilian and environmental concerns over unexploded ordnance.

A method to condition honey bees to search for a non-rewarding producing target odor source enables bees to identify a number of chemical substances such as those associated with unexploded ordnances, land mines, and illicit drug laboratories. Further, the subject method can be used to increase pollination efficiency by conditioning the bees to search for a specific vapor from a target crop. The method includes conditioning the bees to the target odor by moving their hives into a staging area. The staging area is located at least two miles from the ultimate site to be searched. The target odor is applied to the hive. Bulk feeders containing the target odor are placed near the hive. The hives are reoriented to the bulk feeders for several days. The hives are then moved to the search site and feeding / conditioning trays containing the target odor are placed nearby. For the first, approximately 24 hours, the bees are fed from the feeding / conditioning trays. Thereafter, periods of feeding and starvation are alternated to encourage the bees to forage and identify the target source. There are several embodiments of the feeding / conditioning trays which present the target odor to the bee during conditioning. Additionally, an automated feeding controller is useful in the conditioning method.
