  • Patent number: 8107894
    Abstract: A modular solid-state MMW power source based on a topology of the lens array amplifier provides both the flexibility to scale output power and effective thermal management. The modular power source includes a single submodule that uses one or more power dividers and one or more solid-state amplification stages to divide and amplify an RF input signal into R amplified RF signals. The submodule is mounted (suitably in the X-Y plane) on the surface of a heat sink, suitably coupled to a cold backplane, to remove heat. R 1:N low loss power dividers route the amplified RF signals to R*N radiating elements. Each of the 1:N power dividers suitably reside in the X-Z plane and are stacked in the Y direction to provide a planar output of the R*N radiating elements in the Y-Z plane. Placement of the amplifier chips on the single submodule decouples the number of amplifier chips, hence output power, from the number of radiating elements.

  • Patent number: 7889499
    Abstract: There is disclosed a self-contained electronic apparatus containing at least some power-dissipating components which may require cooling. The self-contained electronic apparatus may also include a removable and replaceable energy storage module. The removable and replaceable energy storage module may include a power element to provide electrical energy for the self-contained electronic apparatus and a cooling element to cool at least a portion of the power dissipating components.

  • Patent number: 7784390
    Abstract: There is disclosed a solid state non-lethal directed energy weapon. The non-lethal weapon may include a solid-state source to generate a high-power millimeter-wave initial wavefront, a main reflector, and a sub-reflector to reflect the initial wavefront to the main reflector. The main reflector may direct the reflected wavefront in a bore-sighted direction toward a target. The wavefront directed by the main reflector may have a power density selected to deliver a non-lethal deterring effect on the target.

  • Patent number: 7730819
    Abstract: A portable weapon comprises a non-lethal portion and a lethal portion. The lethal portion may comprise a rifle, and the non-lethal portion may comprise a millimeter-wave directed energy weapon. The non-lethal portion may comprise a kit to add non-lethal capability to a lethal weapon. The non-lethal portion may comprise an output antenna to generate a high-power millimeter-wave initial wavefront, a main reflector, and a sub-reflector to reflect the initial wavefront to the main reflector. The main reflector may direct the reflected wavefront in a bore-sighted direction toward a target. The wavefront directed by the main reflector may have a power density selected to deliver a non-lethal deterring effect on the target. In some embodiments, the non-lethal portion may include a replaceable energy-storage module.

  • Patent number: 6083452
    Abstract: A radome is fabricated by mixing a mass of ceramic powders, a dispersant chemical, a prepolymer material, and a solvent together to form a casting mixture, which is then cast into a mold having the shape of a radome. The prepolymer material in the casting mixture is cured, and the casting mixture is dried. The molded article is heated to a burnout temperature sufficiently high to vaporize the prepolymer material and the dispersant chemical, and thereafter the molded article is heated to a sintering temperature sufficiently high to sinter the ceramic particles.
