  • Patent number: 10601142
    Abstract: Reflecting systems, such as reflector antenna systems, can include a first and a second reflector, and a sub-reflector positioning apparatus. The sub-reflector positioning apparatus has a tensioner attached to the second reflector and configured to exert a force on the second reflector. The force urges the second reflector away from the first reflector. The sub-reflector positioning apparatus also includes a plurality of restraints attached to the first and second reflectors. The restraints are configured to be tensioned in response to the force on the second reflector, and to restrain the second reflector at a pre-determined position in relation to the first reflector.

  • Patent number: 10323935
    Abstract: An alignment reference module (ARM) for detecting an alignment of a hologram with respect to a spindle axis of a spindle that supports an optic device under test (DUT). The hologram is employed for testing an optical surface of the DUT. The ARM includes a flat portion having a reflective surface for reflecting light back toward the hologram member to detect tilting of the hologram relative to the spindle axis. The ARM also includes a spherical portion having a reflective surface adjacent the flat portion for transmitting light back toward the hologram member to detect a radial position of the hologram relative to the spindle axis.

  • Patent number: 10279904
    Abstract: The present invention discloses a fixed-structure vertical takeoff and landing aircraft based on the two flight control systems. The aircraft comprises an aircraft structure and the flight control systems. The aircraft structure comprises a fuselage, fixed wings, a steering engine system and a plurality of engines installed on the peripheral side of the fuselage or the ends of the fixed wings. The flight control systems include the multi-rotor flight control system and the fixed-wing flight control system which are relatively independent or integrated in the same flight control system. Free switching between a multi-rotor vertical takeoff and landing mode and a fixed-rotor high-speed cruising mode is achieved by controlling opening and closing of output channels of the multi-rotor flight control system and the fixed-wing flight control system relative to the steering engine system and the engines through a computer.
