Abstract: A ship having identifiable radar hot spots along its length is protected against radar homing missile attack by a floating decoy, which may be towed. The decoy has a plurality of radar return signal generators spaced along its length, with the amplitudes and spacing of the generators emulating the amplitudes and spacing of the hot spots. The homing missile is seduced away from the ship and toward the decoy.

Abstract: A device for reducing a thermal signature of a person includes: a hood sized and configured to cover a head of a person, having an inner substantially waterproof layer, an outer water wicking layer, and at least one tube having a plurality of openings therethrough attached to the inner layer; and a pump in fluid communication with the tubes to urge water into the tubes and cause the tubes to dispense water to the outer water wicking layer via the openings.

Abstract: An ice-inhibition system for a communications or a radar antenna having an aperture includes a membrane placed before the antenna aperture and secured to the antenna along the antenna's perimeter. The membrane has one or more membrane excitation points identified thereon and when an outward membrane excitation force is delivered to the one or more excitation points, a shock wave is generated at each of the one or more membrane excitation points and propagates away from the membrane excitation points along the membrane toward the perimeter region removing any ice crystals formed on the outer surface of the membrane.
