  • Patent number: 11630804
    Abstract: In an approach for classifying and storing multiple layers of a file system as platform-dependent and platform-independent layers, a processor generates an initial layer of a file system. The initial layer is a platform-dependent base layer. A processor assigns one or more files associated with the initial layer with a first group identification as a first same group in a file registry for a plurality of platforms. A processor generates a new layer based on the initial layer into the file system. A processor, in response to the new layer being platform-independent, marks the new layer as platform-independent in the file registry. A processor pushes the new layer into the file registry for one of the plurality of platforms. A processor distributes one or more corresponding files from the file registry per a client request to access the file system.

  • Patent number: 11630226
    Abstract: A least one seismic attribute is determined for each voxel of the seismic volume. A first horizon is selected for mapping and a sparse global grid is generated which includes the horizon, at least one constraint point identifying the horizon, and a number of points having a depth in the seismic volume. A value of at least one seismic attribute is determined for each point and their depths are adjusted based on the value of the seismic attribute. A map of the horizon can be generated based on the adjusted depths. Multiple local grids can be generated based on the sparse global grid, and the depths of the local grid points adjusted to generate a map of the horizon at voxel level resolution. The seismic volume can be mapped into multiple horizons, where previously mapped horizons can function as constraints on the sparse global grid.

  • Patent number: 11629625
    Abstract: Engine systems and methods use a dual air injection approach to control exhaust reactions and to maintain temperatures below a maximum limit of exhaust system components during engine enrichment operation conditions. Dual air injectors are disposed in the exhaust system with one upstream from, and another downstream from, the catalytic converter. Providing air injection before and/or after the converter helps convert all HC, CO, and PM emissions while keeping the catalyst temperature below the catalyst protection temperature limit. Air injection quantity may be controlled and diagnosed by monitoring the temperatures before and after the catalytic converter. The catalytic converter may be a three-way catalytic converter for lower cost or a downstream two-way catalytic converter may be added if further emission reduction is necessary.

  • Patent number: 11631967
    Abstract: Integrated-optics systems are presented in which an optically active device is optically coupled with a silicon waveguide via a passive compound-semiconductor waveguide. In a first region, the passive waveguide and the optically active device collectively define a composite waveguide structure, where the optically active device functions as the central ridge portion of a rib-waveguide structure. The optically active device is configured to control the vertical position of an optical mode in the composite waveguide along its length such that the optical mode is optically coupled into the passive waveguide with low loss. The passive waveguide and the silicon waveguide collectively define a vertical coupler in a second region, where the passive and silicon waveguides are configured to control the distribution of the optical mode along the length of the coupler, thereby enabling the entire mode to transition between the passive and silicon waveguides with low loss.

    Abstract: A three-phase converter and a control method thereof are provided. The three-phase converter includes an AC terminal, three filter circuits, three bridge arm circuits, a capacitor module and a DC terminal connected in sequence and a controller. The midpoints of the filter circuits are connected to the midpoint of the capacitor module. The controller controls each bridge arm circuit to work in the first and second modes at different time in one line voltage cycle of the AC source. In the first mode, the bridge arm circuit works in a clamping state. In the second mode, the bridge arm circuit selectively works in a DCM mode or a TCM mode. A switching frequency is limited to be lower than a preset frequency. When the three-phase converter works with over 80% of a rated load, a time length of working in the second mode is ?˜? of the line voltage cycle.
