Latest Patents

Dongmei Zhu holds a patent for an "Incremental backup method and system for CAD engineering data file." This patent addresses the challenges associated with the lengthy time required for saving large-scale engineering CAD data files using traditional full backup methods. The patented method involves chunking historical CAD engineering data based on a sliding window approach to determine a first data block group. It calculates a first hash fingerprint value for each data block in this group. The method then chunking the CAD engineering data to be backed up, determining a second data block group, and calculating a second hash fingerprint value for each data block in this group. Finally, it determines the backup status of the data blocks based on the comparison of the two hash fingerprint values. This innovative approach significantly reduces the time required for data backup.
