Abstract:
A device for dismantling explosive devices, the device may include a handle for carrying the robot; a camera; infrared illumination elements; a payload compartment that is configured to hold, in a releasable manner, an explosive device dismantling payload; laser markers that are configured to be at a predefined spatial relationship with an optical axis of the explosive device dismantling payload; a transceiver; a controller that is configured to control the robot, at least partially in response to commands that are received by the transceiver; a base; and a rotation and tilt assembly for moving the payload compartment in relation to the base. The device may be without a driving unit for driving the device from one location to the other.
Abstract:
Disclosed is an apparatus that includes an electric power source that powers a Marx generator that is electrically coupled to a cathode emitter that is configured to discharge electrical potential into the earth. The apparatus also includes a load resistor that is coupled between the output of the Marx generator and either a relative ground or the input to the Marx generator.
Abstract:
A low-cost, reliable and easy to use kit for neutralizing surface exposed landmine and unexploded ordnance for humanitarian demining is based on a liquid fuel and a solid/soluble fuel. Both fuels are premeasured in separate, sealed containers. The addition of a small quantity of solid/soluble fuel into the liquid creates an explosive. The resulting mixture is capable of detonating with a standard No. 8 blasting cap. The solid/soluble fuel can be in the form of a powder, tablet, or its saturated solution in water. The solid/soluble fuel is hexamethylenetetramine. The liquid fuel, nitromethane, is provided in premeasured quantities. User is provided instructions for choosing the appropriate quantity of liquid fuel, the corresponding solid/soluble fuel required, the method of mixing, placement and detonation of the kits. Also disclosed is a simple wooden stand to hold the bottle of explosive in place. A special fuel, liquid 2-ethylhexylnitrate, is provided to desensitize the mixed and sensitized explosive.

Abstract:
A ground pressure detonation device includes a housing, a foot coupled to the housing, and an oscillation subsystem associated with the housing configured to oscillate the housing such that the foot impacts the ground with sufficient oscillating force to ensure detonation of one or more pressure sensitive explosive devices in and/or on the ground.
Abstract:
In an implementation, a roller system is provided. The roller system includes a modular frame. The frame includes a plurality of weight component attachment points. Each weight component attachment point is adapted to receive one or more weight components such that a weight of the frame and location of a center of gravity of the frame is adjusted by the addition of one or more weight components to each of the plurality of weight component attachment points. The frame further includes at least one arm assembly adapted to connect to the frame, and to apply force to a surface, wherein the force applied to the surface is proportional to the weight of the frame and the location of the center of gravity of the frame.
Abstract:
The present invention relates generally to a method and devices for the detection of target objects, such as landmines, using the odor characteristics which may be associated with the target objects as a way of detecting their presence. The invention includes devices used to carry out a method of training live animals, such as rats, to seek out the target objects in the field, or to localize, unearth, and mark the location thereof.
Abstract:
The invention is directed to a system and method for detecting substances, such as high boiling and low vapor pressure materials, using high energy radiation imparted by a suitable radiation source, such as a strobe or laser over a short time period.
Abstract:
A forwarding looking ground penetrating mine detection apparatus includes a radiation source for irradiating a sample of ground suspected of containing at least one mine with a plurality of frequency swept ground penetrating radar signals. A detector receives target signals backscattered from the ground responsive to the radar signal. The detector includes a time-frequency analyzer which transforms the target signals into a time-frequency image representation (TFR). In a preferred embodiment, the detector can include a wavelet packet transformer (WPT) for extracting time-frequency localized information from the TFR in the form of feature set constructed from a wavelet table. The apparatus can also include a data dimensionality reducer for selecting features to form a feature subset from the feature set, preferably based on reference to a training data set. A multilayer neural network classifier can be based on the feature subset, and be adaptable to the surrounding environment through learning.
Abstract:
A coalbed methane borehole pipe liner perforation system comprises a plastic pipe punch that slips down inside a coalbed methane production borehole lined with a non-perforated plastic pipe. A ground-penetrating radar is used inside the plastic-pipe lined borehole to determine which sections of the pipe are in contact with groundwater. The punch is then operated along the length of the plastic-pipe lined borehole to perforate it for methane-gas collection wherever such groundwater is not present. A radar survey to determine groundwater contact can be made simultaneously in combination with the punching of liner pipe perforations, or earlier in a separate operation.
