Abstract: A mine clearing system and method remotely deploys line hose from a remotely controlled two-wheeled vehicle. The wheels are connected together via a central hub shaft. Individual battery operated hub motors on each wheel communicate to a central controller inside the hub shaft. The power source for the motors is contained within the hub shaft, with battery recharge ports located on the hub shaft. The line hose is wrapped around the central hub shaft. An operator uses a remote control console in communication with the central controller to independently control each wheel of the vehicle. A camera can hang from a hub shaft bearing on the outside of one wheel so as to be gravitationally stabilized during vehicle movement. The camera can broadcast signals to a display at the remote control console. Explosive slurry is pumped into the line hose and detonated.

Abstract: A system for reducing the operational efficiency of a watercraft's propulsion system includes a self-propelled and variable-speed unmanned underwater vehicle (UUV) that has at least one homing device adapted to direct the UUV towards an origin of a targeted watercraft's propulsion wake. At least one rod is coupled to a forward end of the UUV and extends forward therefrom at least when the UUV is in proximity to the origin of the targeted watercraft's propulsion wake. At this point, the UUV is directed and accelerated to drive the rod into the targeted watercraft's propulsor.

Abstract: A structure, e.g. a pop-up tent, usable in extremes of temperature, wind, and aridity. One side of the structure's fabric reflects heat, and the other absorbs heat. The structure is reversible, so that, depending which side is outside and which inside, the structure either rejects or absorbs ambient heat, making the structure cooler in hot environments, and warmer in cool environments. The structure can have a detachable base with a hollow chamber in which one can put thermally insulating fluid (e.g. water) to add further comfort, which also provides additional physical and thermal stability to the structure. An optional moisture collector is disposable inside to collect condensate for recycling, and the fabric of the structure can be hydrophobic to direct other condensate to the base and away from occupants.
