  • Patent number: 11183768
    Abstract: A method for deploying a trough structure. The methods comprise: causing a first telescoping segment to move in a first direction away from a proximal end of a telescoping boom; and transiting a flexible element from an untensioned state to a tensioned state as the first telescoping segment is moved in the first direction. The flexible element is coupled to a distal end of the first telescoping segment by a first bulkhead and is coupled to a distal end of a second telescoping segment by a second bulkhead. The first telescoping segment is coupled to the second telescoping segment of the boom when the first telescoping segment reaches an extended position. The flexible element has a parabolic trough shape when in the tensioned state.

    Abstract: An inflatable non-imaging solar concentrator based concentrating solar thermal and photovoltaic system powered water desalination system comprises a concentrating electricity and heat cogeneration subsystem, a battery storage subsystem, a thermal storage subsystem with electric heater, a thermal power regeneration subsystem, and a water distillation system with electric heater. The inflatable non-imaging solar concentrator makes the concentrating system substantially low cost, and the hybrid solar thermal and photovoltaic panels used to construct the cogeneration receiver make the system ultra-high efficient. The cogenerated thermal energy is stored in a thermal storage and the cogenerated electric energy is stored in a battery storage to heat the stored thermal energy to pre-set high temperature for thermal power regeneration. The thermal energy after thermal power generation is used to desalinize water with assistance of electric heater powered by the stored electricity.

    Abstract: Apparatus for improving the performance and allowing increased directionality of reflecting-type antenna systems by varying the geometry of the reflecting surface. A reflecting surface is composed of an array of actuated pins which are capable of extending or retracting to alter the overall pattern. An actuator controlling unit has the address of each actuator and is able to extend or retract the pins to the desired degree. The specific pattern which the actuator control unit realizes is determined by the iterative position calculator which utilizes directional inputs from the user and/or inputs from a system which determines the effectiveness of previous pin movements. The apparatus attempts to maximize the received signal by assessing amplitude changes over time and utilizing that information to direct alteration in the reflecting surface for optimal performance.

  • Patent number: 8558734
    Abstract: A ground based avian radar receive antenna is implemented using a vertically oriented offset parabolic cylindrical antenna. The desired azimuth beamwidth is determined by the width of the parabolic cylinder reflector surface and the desired elevation beamwidth by the height of the parabolic cylinder reflector surface. A vertical array of antenna elements is mounted along the vertical focal line to provide electronic scanning in elevation. Low sidelobe levels are obtained using tapered antenna element illumination. Low cost modular construction with high reflector accuracy is obtained by attaching a thin metal reflector to thin ribs machined or stamped in the shape of the parabolic cylinder reflector surface. The antenna is enclosed in a radome and mechanically rotated 360 degrees in azimuth.

  • Patent number: 8508430
    Abstract: An antenna reflector (100, 700) comprising a centrally located hub (120), inner ribs (108) rotatably secured at a proximal end to the hub, outer ribs (110) extendible from the inner ribs, and a guideline truss structure (132, 160) configured to support a flexible antenna reflector surface (122). The inner ribs are rotatable from a stowed position in which they are generally aligned with a central axis of the hub, to a rotated position in which they extend in a radial direction relative to the central axis. The guideline truss structure is secured to each outer rib using standoff cords attached at intermediate locations along a length of the outer rib between opposing ends (116, 118) thereof. The outer ribs are configured to be linearly displaced respectively along an elongated length of the inner ribs from a proximal position adjacent to the hub, to an extended position distal from the hub.

  • Patent number: 8487830
    Abstract: The invention proposes a solution to the problem of installing an antenna with long focal length on a satellite, and, as a non-limiting example, on satellites at a height that is less than the required focal length. It is based, on the one hand, on a reflector stored “inverted and head down”, and, on the other hand, on a deployment movement sequence employing a long arm taken up in the top portion of the reflector via an articulation (1 axis) and a conventional deployment mechanism (1 or 2 axes).

  • Patent number: 8462078
    Abstract: A reflector useful for communications, radar and sensing application in space and on earth includes thin shell gores emanating from a geometric center of the reflector at its hub. Gores are provided in a spiraled pattern and are in elastic connection to said hub and wrapped around their point of convergence at the hub when the reflector is stowed. The gores emanate from the geometric center of the reflector hub at their elastic connection to the hub when they are deployed and operational as a reflector with a point of convergence to promote operation as a reflector. Thin shell gores can have an inner perimeter and outer perimeter, can be provided in a spiraled pattern, and can be interlocked at their outer perimeter, or in-between their inner and outer perimeter, while also remaining in elastic connection at their inner perimeter to said hub.
