  • Work machine with automatic pitch control of implement
    Patent number: 11926988
    Abstract: A system and method for automatically adjusting the pitch of a work implement attached to a work vehicle, wherein the work implement has adjustable wings. The system and method include moving materials with a blade having an adjustable wing located at one end of a center portion of the blade. blade operatively connected to the work vehicle is positionable with respect to the work vehicle in response to an operator command. A commanded position of the blade is identified based on a blade positioning signal received from the operator command transmitted by an operator control device. An inclined position of the adjustable wing with respect to the center portion of the blade is identified. A pitch of the blade with respect to the work vehicle based is automatically adjusted based on the identified commanded position of the blade and the identified inclined position of the adjustable wing.

  • Gyrotron whispering gallery mode coupler with a mode conversion reflector for exciting a circular symmetric uniform phase RF beam in a corrugated waveguide
    Patent number: 9715988
    Abstract: A cylindrical waveguide with a mode converter transforms a whispering gallery mode from a gyrotron cylindrical waveguide with a helical cut launch edge to a quasi-Gaussian beam suitable for conveyance through a corrugated waveguide. This quasi-Gaussian beam is radiated away from the waveguide using a spiral cut launch edge, which is in close proximity to a first mode converting reflector. The first mode converting reflector is coupled to a second mode converting reflector which provides an output free-space HE11 mode wave suitable for direct coupling into a corrugated waveguide. The radiated beam produced at the output of the second mode converting reflector is substantially circular.

  • Multi-mode horn
    Patent number: 6411263
    Abstract: A horn has an input aperture and an output aperture, and comprises a conductive inner surface formed by rotating a curve about a central axis. The curve comprises a first arc having an input aperture end and a transition end, and a second arc having a transition end and an output aperture end. When rotated about the central axis, the first arc input aperture end forms an input aperture, and the second arc output aperture end forms an output aperture. The curve is then optimized to provide a mode conversion which maximizes the power transfer of input energy to the Gaussian mode at the output aperture.

  • Gyrotron with a mode convertor which reduces EM wave leakage
    Patent number: 5180944
    Abstract: In a gyrotron having an annular collector for an expanded e-beam and a gyrotron output waveguide with an annular gap for passing the expanded e-beam is provided with a mode converter between the resonator and the gap to shift more energy to the waveguide central axis to decrease EM field leakage coupling through said gap.
