  • Patent number: 10951110
    Abstract: Disclosed in embodiments of the present invention are a control method and device for an alternating-current and direct-current conversion circuit, and a computer storage medium. The alternating-current and direct-current conversion circuit comprises a first commutation unit, a second commutation unit, and a coupling unit. By obtaining voltage information and current information of the alternating-current and direct-current conversion circuit, a controllable device of the first commutation unit can be controlled to be turned on in delay or turned off in advance; and the second commutation unit is controlled to work in a controllable rectification state or a controllable inversion state or an uncontrollable rectification state.

  • Patent number: 10168447
    Abstract: A method, apparatus, and computer-readable medium provide automatic geosteering by automatically updating a geosteering structure model based upon observed data gathered during a drilling operation. In some embodiments, automatic updates may be used to introduce vertical shifts into a geosteering structure model to match synthetic log data with observed log data. In addition, in some embodiments an evolutionary algorithm may be used to introduce such vertical shifts and thereby provide an optimal match between the synthetic and observed log data.

  • Publication number: 20170219343
    Abstract: The present invention provides a Fabry-Perot sensor for measuring inclination. Wherein the present inclinometer is fixed on a static detected object in application use, the mass block is flexibly connected to the top plate, thus the line between the center of gravity of the mass block and the connecting point on the top plate is perpendicular to the horizontal plane; a Fabry-Perot cavity is formed between the reflecting surface disposed at one end of the mass block and the end of the optic fiber. The detected object will be in a static state after tilting, the line between the center of gravity of the mass block and its connecting point on the top plate is still perpendicular to the level plane and the F-P cavity length will have a variation. Then the change of cavity length can be measured in accordance with the Fabry-Perot principle, thereby the tilting angle of the mass block is able to be further measured. Then the tilting angle is also the inclination of the detected object.

  • Patent number: 9686892
    Abstract: Optical windows based on a multi-period master-slave nested ring array of concentric rings are suited for electromagnetic shielding. A metal grid of the ring array has basic rings, concentric sub-ring pairs, secondary sub-rings, filling rings, concentric modulation ring pairs, and modulation sub-rings. Basic rings and concentric modulation ring pairs form a two-dimensional orthogonal array. External rings of concentric modulation ring pairs are externally tangentially connected to basic rings. Concentric sub-ring pairs and filling rings are arranged within basic rings, secondary sub-rings are arranged within concentric sub-ring pairs, and modulation sub-rings are arranged within concentric modulation ring pairs. Where rings are tangentially connected, wires overlap or metal ensures reliable electrical connections between connected rings, thus all rings are conductive.

  • Patent number: 9668391
    Abstract: An optical window based on an array of rings and sub-rings having a triangular and orthogonal mixed distribution is suited for electromagnetic shielding. The array has metal rings of the same diameter acting as basic rings closely arranged according to an equilateral triangular and two-dimensional orthogonal square mixed arrangement and is loaded on an optical window transparent substrate surface. Adjacent basic rings are connected externally tangentially. Metal sub-rings are arranged within each basic ring and connected thereto internally tangentially. Each basic ring and its sub-rings constitute a basic unit. At tangential connection locations of the rings, wires overlap or metal is provided to ensure reliable electrical connections between connected rings, thus all rings are conductive.
