  • Patent number: 10915407
    Abstract: The Source Volume Backup with Adaptive Finalization Apparatuses, Methods and Systems (“SVBAF”) transforms backup request inputs via SVBAF components into backup response outputs. A set of blocks to be copied from a source volume to a target volume is designated and copied while an operating system is configured to write to the source volume. Blocks of the source volume that were written to by the operating system while the operating system was configured to write to the source volume are identified. Finalization settings are analyzed to determine whether to enter a CoW mode. If the CoW mode should not be entered, the designated set of blocks is changed to include at least one of the identified blocks and a pass is repeated. Otherwise, the operating system is instructed to enter the CoW mode and bring the target volume into a state consistent with a state of the source volume.

  • Patent number: 10844544
    Abstract: A method of measuring hydrophobic contaminants in a pulp slurry or a papermaking system includes the steps of providing an aqueous paper mill sample, filtering the aqueous paper mill sample to produce a filtrate comprising particles, and collecting an image of the particles in a measured volume of the filtrate. The method also includes the steps of analyzing the image to determine a size and morphology of the particles in the measured volume of filtrate, identifying spherical particles having a size of from about 1 micron to about 20 microns in the measured volume of filtrate, and quantifying a number of the spherical particles having the size of from about 1 micron to about 20 microns in the measured volume of filtrate. This method is useful for papermakers for deposition diagnostics, prevention, and contaminant control treatment optimization.
