  • Patent number: 8989334
    Abstract: An aneutronic magnetron energy generator that generates microwave energy from a fusion-fission reaction that produces alpha particles in response to a proton colliding with an 11B nucleus. The magnetron energy generator includes a magnetron having an anode resonator including a central chamber and a plurality of radially disposed cavities. A cathode assembly is provided at the center of the chamber and includes a cathode electrode that generates a proton plasma. A series of electrically isolated acceleration rings extend from the cathode electrode and operate to accelerate protons from the proton plasma towards an outer target ring composed of boron eleven (11B). The accelerated protons fuse with the 11B nuclei to generate the alpha particles that then interact with crossed electric and magnetic fields between the target ring and the cavities. The alpha particles resonate with the cavities and generate a current within the resonator that is collected.

  • Patent number: 8836793
    Abstract: True color images are produced by combining data collected from one or more color cameras with data collected from one or more infrared cameras. The produced images are the result of combining portions of the visible light data with portions of the infrared light data that may have been captured at dark, at daytime or at low light level conditions. These images appear as normal color images, with infrared information highlighted in a non-distracting fashion. The true color images that are produced in this fashion can also facilitate identification and reproduction of various objects that may not be visible or readily identifiable in infrared or false color imagery.

  • Patent number: 8497479
    Abstract: A thermal infrared camera may be used under a wide variety of target-scene radiation conditions, with interchangeable or zoom lenses requiring matching or different size cold stops. A variable aperture assembly of a thermal infrared camera integrates a rigid open truss-like framework that's capped by an aperture ring and bottomed by a driving ring, and a radiation shield, located inside the framework, that contains an aperture ring at an upper side. A plurality of blades that collectively define an aperture positioned between the upper aperture rings. Opposite blade ends are coupled to respective ones of the two aperture rings, permitting pivotal movement in one ring and radial movement in the other ring, when the rings are rotated relative to one another, to change the size of the formed aperture. Both refractive and reflective infrared telescopes may be retro-fitted with variable aperture devices to enhance infrared imaging performance.

  • Patent number: 8466964
    Abstract: A multispectral thermal infrared camera system is disclosed. An uncooled thermal imaging camera is equipped with an axially tilted, cooled spectral filter. The axially tilted, cooled spectral filter deflects the radiation emitted by the uncooled camera away from being reflected back into the camera. The axially tilted, cooled spectral filter emits a lesser amount of thermal radiation towards the camera. And the axially tilted, cooled tilted filter is enclosed in a cold radiation shield to minimize the thermal emission that would be reflected by the filter towards the camera and to absorb the radiation deflected by the tilted filter. The axially tilted, cooled spectral filter passes only the desired portion of the thermal infrared radiation from the scene onto the uncooled camera.

  • Patent number: 8462418
    Abstract: A continuous variable non-circular aperture for an infra-red camera is formed by a plurality of positionable metal blades arranged to define there between an aperture of non-circular shape. A rotatable actuator plate positions the blades. Actuator rotation in one direction moves the metal blades to increase the size of the non-circular aperture without changing the non-circular shape of the aperture and vice-versa when the actuator plate is rotated in the opposite direction also maintaining the non-circular aperture shape. A preferred non-circular shape for a continuous variable aperture now possible is a rectangle; another is configured as a racetrack.

  • Patent number: 8071947
    Abstract: A variable aperture assembly for an infrared camera for use with optics having two or more f-numbers. The variable aperture assembly includes a variable iris disposed substantially along an axis of the infrared camera and is thermally connected to a cooling assembly. The variable iris is capable of causing an infrared radiation admitting opening to vary in size. The infrared radiation admitting openings of the variable aperture assembly can be circular or non-circular, including generally rectangular or racetrack shaped openings. The variable aperture assembly provides f-number matching by adjusting the infrared radiation admitting opening to the size necessary to effectively match the numerous f-numbers of the optics, or by adjusting to a size so that a fixed aperture on the radiation shield becomes the effective aperture stop, providing the f-number matching.

  • Patent number: 7149928
    Abstract: The present invention, generally speaking, “instruments” an arbitrary software program, without changing the software program, to automate malfunction detection and reporting. Although users can be invited to enter a description of what the user was doing prior to receiving the error, report generation and transmission to a remote server can be fully automatic and transparent to the user. In the case of beta testing, therefore, a software developer is guaranteed to receive all pertinent information about malfunctions of an application without having to rely on “fallible humans” for this information. The effectiveness of beta testing, in terms of ultimately contributing to an improved product, is therefore greatly increased. Various kinds of malfunctions may be detected and reported, including an application “crashing,” becoming “hung,” etc.

  • Publication number: 20060017816
    Abstract: A line of sight stabilization system using two mirrors pivotally mounted to a fixed platform that can be used with existing imaging systems to provide pitch, roll, and yaw compensation while maintaining image orientation. By deflecting only the photons, the inventive system avoids the need to stabilize the entire imaging sensor and optics system. The only mass to move is that of the two imaging system mirrors. By monitoring attitude changes via an inertial measurement system, proceeding platform positions can be estimated for subsequent image acquisitions, and efficient mirror positioning can provide optimal image orientation and stabilization. This approach requires small motors with low torque, providing a less expensive, lightweight, and small image orientation and stabilization system.
