Publication number: 20250167640Abstract: A common mode line-to-ground filter is disclosed which includes but is not limited to a resistor, capacitor and a ground. The common mode line to ground filter is connected on a high side of a step-up transformer. A low side of the step-up transformer is connected to a variable frequency drive that provides a semi-sinusoidal voltage waveform. The common mode line to ground filter generates a filtered sinusoidal waveform from the output of the step-up transformer. The filtered sinusoidal voltage waveform is supplied via an electrical cable to an electrically submersible pump deployed downhole.Type: ApplicationFiled: November 18, 2024Publication date: May 22, 2025Applicant: MAGNEY GRANDE DISTRIBUTION, INC.Inventors: Salvatore F. Grande, III, Leo Stephen Coombs

Publication number: 20250057424Abstract: Various examples are provided related to dynamic brain parcellation. In one example, a method for functional task prediction with dynamic supervoxel parcellation includes preprocessing activation data obtained from brains of multiple subjects to generate one or more dynamic parcellated supervoxel maps of the brain, the activation data associated with a functional task, and determining an anatomical location of the functional task in the brain of another subject based upon classification of supervoxels of the one or more dynamic parcellated supervoxel maps. In another example, a system includes at least one computing device that can preprocess activation data to generate one or more dynamic parcellated supervoxel maps of the brain, the activation data associated with a functional task, and determine an anatomical location of the functional task based upon classification of supervoxels of the one or more dynamic parcellated supervoxel maps.Type: ApplicationFiled: December 16, 2022Publication date: February 20, 2025Inventors: Ruogu Fang, Kyle B.
