US11327663B2	Ensuring the integrity of data storage volumes used in block-level live synchronization operations in a data storage management system An illustrative live synchronization feature uses file system block-level backup copies, snapshot techniques, change tracking, and volume-level granularity to ensure the integrity of destination volumes. Two protection mechanisms guard the destination data and ensure consistency from one live sync restore to the next. First, an inter-job software snapshot captures the destination volume image after each restore. The snapshot is created at the very end of each live sync restore and is reverted at the beginning of the next live sync restore. A second and more granular protection mechanism uses intra-job block monitoring to detect, and later to reverse, changes that the snapshots cannot capture. This second mechanism acts as a mini-block-level restore nested inside another block-level restore. This dual approach ensures that each incremental live sync restore finds the destination volume with a guaranteed pristine image identical to where the preceding live sync restore left it.

US11327187B2	Functional quantization based data compression in seismic acquisition Seismic acquisition having high geophone densities is compressed based on Functional Quantization (FQ) for an infinite dimensional space. Using FQ, the entire sample path of the seismic waveform in a target function space is quantized. An efficient solution for the construction of a functional quantizer is given. It is based on Monte-Carlo simulation to circumvent the limitations of high dimensionality and avoids explicit construction of Voronoi regions to tessellate the function space of interest. The FQ architecture is then augmented with three different Vector Quantization (VQ) techniques which yield hybridized FQ strategies of 1) FQ-Classified VQ, 2) FQ-Residual/Multistage VQ and 3) FQ-Recursive VQ. Joint quantizers are obtained by replacing regular VQ codebooks in these hybrid quantizers by their FQ equivalents. Simulation results show that the FQ combined with any one of the different VQ techniques yields improved rate-distortion compared to either FQ or VQ techniques alone.
