  • Publication number: 20240046680
    Abstract: A system and method for correcting image data is disclosed. The method includes receiving one or more documents from one or more electronic mediums. The method further includes determining a primary character and one or more alternate characters corresponding to the mis-captured character image, extracting one or more confident instances of the primary character and the one or more alternate characters from the one or more documents and generating one or more scores corresponding to the primary character and the one or more alternate characters. Further, the method includes predicting a correct character corresponding to the mis-captured character image by using a trained image prediction-based ML model and automatically replacing the mis-captured character image with the predicted correct character.

  • Patent number: 10141837
    Abstract: Device and method for energy harvesting using a self-oscillating power-on reset start-up circuit. The device for energy harvesting comprises a start-up circuit for generating self-oscillation and initial boosting of an input voltage from an energy source during a start-up phase; a main boost circuit for boosting the input voltage during a steady state phase; a clock generator circuit for generating clock signals which control voltage boosting of the main boost circuit during the steady state phase; and a switching circuit coupled to the start-up circuit, the main boost circuit and the clock generator circuit for switching powering of the clock generator circuit between the start-up circuit and the main boost circuit such that the clock generator circuit is powered by only one of the start-up circuit and the main boost circuit at any point in time.

  • Patent number: 10142415
    Abstract: Data migration data may include analyzing data to be migrated from a first device to identify data blocks containing content that is the same at an abstraction layer and constructing a content map. Entries in the content map may respectively correspond to unique contents found at the abstraction layer, and each of the entries may include a list of addresses at which the unique content corresponding to the entry can be found. The unique contents may be sent from the first device to the second device and written in the second device at addresses selected based on the content map and using the abstraction layer in the second device.

  • Publication number: 20120005307
    Abstract: A method of providing access to a plurality of different file systems implemented across a plurality of storage spaces comprises receiving a request for at least one storage space. The method further comprises receiving a request for at least one storage space and processing the request based at least in part on one of a location metadata and a file metadata, the location metadata including attributes associated with the plurality of storage spaces and the file metadata including attributes associated with one or more files stored at the plurality of storage spaces.

  • Publication number: 20100293145
    Abstract: A method includes identifying with a server a first range of data blocks in a storage device array corresponding to data files selected for replication, the first range of data blocks being managed by a source host device; mapping the first range of data blocks to a second range of data blocks in the storage device array managed by the destination host device; copying the data blocks from the first range that contain the data files selected for replication to the corresponding data blocks in the second range; deleting files in the copied data blocks of the second range that have not been selected for replication; and condensing the second range of data blocks.
