Disclosed is a masking material intended to be disseminated by an ammunition or a launcher to create a cloud that masks a target with respect to electromagnetic radiation in a given wavelengths range. This material contains at least one aluminium oxyhydroxide, such as boehmite or pseudoboehmite. Also disclosed is an ammunition enabling the dissemination of such masking material and the use of aluminium oxyhydroxide, such as boehmite or pseudoboehmite as a masking material that can be disseminated by an ammunition.

The invention proposes an apparatus for generating three-dimensional visual effects, characterised in that it comprises, in combination: a controlled smoke generator (10) comprising a synthetic smoke source and a means for directionally propelling the smoke produced by the generator in order to form a plume of smoke extending in a certain direction, and a controlled light generator (20), suitable for generating one or more light beams in the plume of smoke and in the direction in which it extends, the light beam or beams being essentially contained in said plume of smoke. Application in particular to the production of lightsaber visual effects, and more generally to varied three-dimensional light effects.

Systems and methods for modifying an infrared signature of a vehicle are provided. A method may include producing an aerosol cloud proximate the vehicle. The method may further include determining one or more characteristics of the aerosol cloud. The method may also include determining a projection plane within the aerosol cloud based on the aerosol cloud characteristics for projecting a representation of the object. The method may additionally include providing heat at particles in the projection plane of the aerosol cloud to generate the object representation.

A portable Doppler microwave radar defense system that saves lives in dangerous situations, and alerts a person from surrounded threats, exposes enemy location, and shows the health data and injured person's location to remote server at a base. The system lets the person know about the surrounded threats before it happens, as it will detect any bullets in the detection zone and alert the person immediately from the incoming bullet within a long range which will let the person have seconds to avoid the bullet and save his life and the location of the shooter will be exposed to the person. The detection system can also be deployed over an object such as a car, truck, battle tank, aircraft, jet, helicopter, spaceship, or a satellite.

A fog-generating device (1) is described, comprising a heat accumulator to store thermal energy and release it to a fog-generating fluid, to produce steam, and a thermal mass composed of a plurality of small metal plates (11, 12, 13, 14, 15, 16, 17, 18, 19, 20) housed, inside a container (2), in order to locate a path of the fog-generating fluid adapted to lick the surface of the small metal plates (11, 12, 13, 14, 15, 16, 17, 18, 19, 20), generating a vaporization of the fog-generating fluid.

This disclosure relates generally to a Multiple Payload Expendable Device consisting of a set of cylindrical multiple payload casings, each payload casing exhibiting circular symmetry fluid passages in relation to firing squibs and voltage coded squib actuating circuit that converts existing single payload expendable device systems to multiple payload expendable device systems.

A prompting device for prompting state information of a physical game character includes a smog machine and a control circuit. The smog machine include a smog chamber, a heating element, and an air-blowing device. The smog chamber has a receiving cavity for receiving smog fluid, an inlet, and an outlet. The inlet and the outlet are in communication with the receiving cavity. The heating element is mounted within the receiving cavity and generates heat to vaporize the smog fluid after an electric current is applied. The air-blowing device is disposed corresponding to the outlet for blowing an air flow towards the receiving cavity. The air flow generated by the air-blowing device enters into the receiving cavity from the inlet and discharges smog within the receiving cavity from outlet. The control circuit is configured to control the smog machine to generate the smog that characterizes the state information.

A mixture and method of creating the mixture includes mixing hexachloroethane, stannous oxide, and aluminum together. The mixture may be loaded into at least one canister. The mixture may be combusted to create a smoke screen. The loading of the mixture into the at least one canister may include pressurized loading at loading pressures in the range of approximately 2300 psi to 3600 psi. The hexachloroethane may include approximately 30-40 parts by weight of the mixture and have a particle size of approximately less than 850 m. The stannous oxide may include approximately 55-65 parts by weight of the mixture and have a particle size of approximately less than 150 m. The aluminum may include approximately 5-10 parts by weight of the mixture and have a particle size of approximately less than 45 m. The mixture is devoid of zinc chloride.
