  • Patent number: 10644626
    Abstract: A method and a system for acquiring a rotor position of a rotary transformer are provided. The system includes: a rotary transformer decoder, a low pass filter and a microprocessor, which includes a synchronous demodulation module and a calculation module. The rotary transformer decoder outputs an excitation signal and acquires first position information of the motor rotor. The calculation module performs calculation to acquire second position information of the motor rotor. The rotary transformer decoder and software decoding are integrated to acquire two rotor positions, and the two rotor positions are compared. In a case that a preset determining condition is met, one of the rotor positions is used for motor control, and the other is used as redundant data for backup, thereby improving the reliability of the acquired rotor position.

  • Patent number: 10613976
    Abstract: The present disclosure directs to solutions for performing deduplication by a storage device. In the solutions, according to a duplicate data locality principle, non-duplicate data blocks whose logical addresses are contiguous are stored in contiguous physical addresses in a sequence of the logical addresses, and fingerprints of the non-duplicate data blocks whose logical addresses are contiguous are also stored in contiguous physical addresses in the sequence of the logical addresses, and in addition, a mapping from a logical address, which is of one data block in the non-duplicate data blocks whose logical addresses are contiguous, to an aggregation address is established.

  • Patent number: 10542062
    Abstract: Embodiments of the present invention provide a method for searching for a data stream dividing point based on a server. In the embodiments of the present invention, a data stream dividing point is searched for by determining whether at least a part of data in a window of M windows meets a preset condition, and when the at least a part of data in the window does not meet the preset condition, a length of N*U is skipped, so as to obtain a next potential dividing point, thereby improving efficiency of searching for a data stream dividing point.

  • Patent number: 10540240
    Abstract: Embodiments of the present disclosure disclose a solution for data backup and recovery in a storage system. When a source device in the storage system backs up, to a backup-end device, a data block that is written after a snapshot Sn, the source device performs a logical operation such as an exclusive-NOR or exclusive-OR operation on the written data block and an original data block, which is recorded in the snapshot Sn, of the written data block, and then compresses a data block obtained after the logical operation, which improves a compression ratio of a data block, thereby reducing an amount of data that is sent to the backup-end device, and saving transmission bandwidth. The solution may be further applied to a scenario of data recovery in a storage system.
