  • Patent number: 7954955
    Abstract: A light engine for image display projectors has a plurality of monochromatic light sources, typically red, blue and green, combined into one light generation device powered by microwaves pulsed at 3-5 KHz rates. The light engine has a microwave power supply, microwave coupling cavity, a microwave coupler coupling a microwave signal from the microwave power supply to the microwave coupling cavity, and the plurality of monochromatic light sources disposed in the microwave coupling cavity and powered by the microwave signal. The microwave coupling cavity includes a plurality of resonance points, each of the monochromatic light sources being located respectively at one of the resonance points.

  • Publication number: 20070215946
    Abstract: A new communications system is described in which the phased array heater used to create an artificial ionized plasma pattern in the atmosphere (AIPA) has an integrated phased array transmitter. By combining these two functions a simplified telecommunications system is created. The new system is called the Integrated Plasma Mirror. Another advantage is that a portion of the telecommunications signal is absorbed in the plasma pattern and contributes to the maintenance power level.

  • Patent number: 6425663
    Abstract: A microwave ink drying apparatus for an ink jet printer includes a microwave applicator. The applicator may be attached to a movable print carriage. The applicator may further comprise a slot antenna. The slot antenna may be formed as a dual slot, with one portion of the slot coupled to a wave launching cavity, and the other portion of the slot coupled to an impedance matching cavity.

  • Patent number: 5868909
    Abstract: This invention provides methods and apparatus for continuously and efficiently separating the elements in a complex substance such as radioactive waste with a large volume plasma processor. One principal methods utilizes plasma confinement by toroidal magnetic fields with a poloidal divertor magnetic field and converts the plasma from a process plasma to a product plasma at a rapid rate permitting injection of a series of pellets, droplets or streams while the toroidal current in the plasma is maintained. A second principle method involves reducing the radiation losses in the separation process by eliminating the toroidal section and directly converting the feedstock material to a product plasma in an elongated evacuated container surrounded by magnetic field generating coils which produce magnetic fields that are parallel to the long axis of the evacuated container,The apparatus is a large volume plasma processor with multiple containment vessels.

  • Patent number: 5681434
    Abstract: This invention provides methods and apparatus for ionizing all the elements in a complex substance such as radioactive waste and for separation of some of the elements from the other elements. One principal methods utilizes plasma confinement by toroidal magnetic fields as a gate to regulate when and where specific elements are collected. While the plasma is confined, some of the species are removed by repeatedly cycling all of the species between the plasma and the deposition stages lining the walls, whereby some species preferentially accumulate on the deposition stages. The other species are then diverted into an additional containment vessel for collection or additional separations. The apparatus is a large volume plasma processor with multiple containment vessels. The invention provides for the characterization of waste material, and for its separation all within one serf contained vacuum environment. Other applications include remediation of chemical toxic wastes and chemical and germ warfare weapons.

  • Patent number: 4042850
    Abstract: An apparatus for efficiently coupling microwave energy to a highly dissipative load such as a plasma lamp tube. A longitudinally extending lamp tube is enclosed in a longitudinally extending non-resonant microwave chamber having a pair of coupling slots therein which are oriented perpendicular to the direction of the lamp tube. The slots are azimuthally offset in opposite directions with respect to a longitudinally extending top center line of the chamber by about 15.degree. to 20.degree., and are located near respective ends of the chambers but at different distances therefrom. Microwave energy from a pair of microwave energy generating means is coupled to the respective slots with the frequency outputs of the generating means being offset from each other by a small amount.
