Abstract: In a method and device for suppressing range ambiguity in Synthetic Aperture Radar (SAR), azimuth transmission-phase modulation is performed respectively, using a preset rule for phase modulation, on pulse signal data transmitted on a channel of Horizontal (H) polarization and pulse signal data transmitted on a channel of Vertical (V) polarization. Full polarimetric echo data corresponding to the transmission-phase modulated pulse signal data transmitted on the channel of H polarization and the transmission-phase modulated pulse signal data transmitted on the channel of V polarization are acquired. Azimuth phase demodulation is performed on the full polarimetric echo data using a preset rule for phase demodulation. Echo data are acquired by filtering out, using a preset azimuth filter, range-ambiguity energy from the phase demodulated full polarimetric echo data.

Abstract: Drying and separation vibrating fluidized bed for processing wet coal by high-temperature hot air. Wet coal is fed into a vibrating separation chamber connected to a hot air supply duct. The wet coal is vibrated as it is dried and is layered as heat and mass transfer occur between the high-temperature air and the wet coal particles. Hot air enters the bottom of separation chamber through a distribution plate that includes asbestos fiber cloth sandwiched between clamping plates. The wet coal is fed through a feeding distribution device that separates the coal pieces as they enter the separation chamber. After the coal is dried and layered, the heavy and light material exits the separation chamber through two discharge impellers.

Abstract: A plasma actuator of the present disclosure comprises a plate electrode; a needle electrode positioned at a height above the plate electrode and a distance away from the plate electrode; and a voltage source connected to the needle electrode. Application of a signal from the voltage source to the needle electrode forms surface corona discharge around a tip of the needle electrode, and air flow driven by the corona discharge from the tip of the needle electrode is induced at a surface of the plate electrode. Accordingly, the air flow that is created can be used to cool a surface, such as a circuit board, a heat exchanger, etc.

Abstract: Embodiments relate to an electromagnetic, or electric, pump for pumping and/or transporting a liquid. Embodiments impart motion to a liquid, so as to stir, mix, circulate, or otherwise move the liquid. Embodiments transport water. The liquids can be conducting or non-conducting. Embodiments pump liquids in pipes. Embodiments utilize a shockwave effect, a magneto hydrodynamic effect, and/or an electrohydrodynamic effect to push the liquid. Embodiments operate with no mechanically moving parts, increasing the reliability of the pump. Embodiments of the electromagnetic (or electric) lifting, or pumping, device are thin such that the electrodes that create the pumping are installed inside the piping of the pump, reducing, or eliminating, sealing/leakage problems. Embodiments create one or more sparks, and/or filament discharges, triggered between one or more pairs of electrodes positioned such that a liquid is between the electrodes of the electrode pair, where the spark, or filament discharge, creates a plasma.

Abstract: A method for achieving high-power solid-state lasers by multiple beams combination using cascaded compound laser oscillators, comprising the following steps: 1) Designing a compound resonator to achieve an output beam perpendicular to the axis of oscillation in which a compensating lens is used; 2) Designing beam combination of two independent solid-state lasers in cascaded compound cavities and using 4f optical system to compensate the beam waist separation between two lasers; 3) Based on the first two steps, multiple beams combination of N independent solid-state lasers can be achieved. In the present invention, N output beams emitted from N independent solid-state lasers are completely combined, and the combined beams hold the same waist position, size and divergence along down the same optical axis. Therefore, it can preserve original beam quality with that of individual solid-state lasers.
