Abstract: A multifunctional track system with two or more independently movable trolleys which can run along the track system and are adapted to receive multiple interchangeable components for data collection, navigation, and cargo transportation is disclosed. The trolleys and the track system communicate data to a central station, which monitors and sends instructions to the trolleys. The system can have horizontal, vertical or angular segments and the trolleys are enabled to move along all segments and switch between tracks. Various operational units in the trolleys are possible in the same system.

Abstract: The invention a multi-purpose, multi-reusable, multi-ejectable grenade and anti rioting device in a single unit. Explosion(s) occur by being thrown after setting the desire pyrotechnic effects. Further Characteristics in that principally consist of four quarter mountable oval shape charges that ejected or launch after being toss and impact with target surface or target object that will occur during detonation process hence create the desired pyrotechnic effects.

Abstract: The Cassu-guard is electrical safety apparatus that is created to prevent electrical shortage, shock & movement of broken wires and eliminate the use of electrical tape in insulating socket outlets and light switches when installing these devices in metallic boxes.

Abstract: An adjustable nozzle dispenser and a multi-nozzle dispenser are disclosed for washing an aerofoil of a gas turbine engine. The dispensers are characterized by their nozzle arrangements being capable of washing at least two different parts of the aerofoil. A system and a method of operating such a nozzle dispenser is included.

Abstract: An illumination source of predominantly non-directional and incoherent millimeter-wave radiation for illuminating an area for passive millimeter-wave imaging comprises a container with at least a partly reflective internal surface and a plurality of exit apertures and a primary source of millimeter-wave radiation for emitting millimeter-wave radiation into the container. The primary source and the container are arranged so that a proportion of the millimeter-wave radiation emitted by the source undergoes reflection within the container before being emitted through the apertures, such that the different paths lengths are at least equal to the coherence length of the radiation. This is facilitated if the bandwidth of the radiation is preferably at least 1 GHz. The container may be a box in which a waveguide is used to couple radiation from the primary source into the box. Alternatively, the container may be formed from a mesh and the plurality of holes is provided by the holes in the mesh.

Abstract: An object detection apparatus which includes a radiation source in the form of an amplifier and a detection arrangement. The apparatus has a tuner which determines a coherence length. The apparatus detects an object which is buried/concealed at a depth, d, is beneath a surface provided that the depth, d is less than the coherence length.
