  • Publication number: 20210076662
    Abstract: Disclosed herein are methods, devices, modules, and systems which may be employed for automated weed identification, control, and eradication. These methods, devices, modules, and systems provide an alternative to hand cultivation or chemical herbicides. Devices disclosed herein may be configured to locate, identify, and autonomously target a weed with a beam, such as a laser beam, which may burn or irradiate the weed. The methods, devices, modules, and systems may be used for agricultural crop management or for at-home weed control.

  • Patent number: 8706755
    Abstract: A distributed file system enables the intelligent storing and retrieval of files among a plurality of storage units. The distributed file system utilizes a metadata data structure to track and manage detailed information about each file, including, for example, the device and block locations of the file's data blocks, to permit different levels of replication and/or redundancy. The distributed file system includes a switch to receive a read request for a file and to send the read request to one of the storage units. Each of the plurality of storage units is operable to monitor access to the file, such that a block cache module is operable to perform a scalable number of packet read aheads, wherein the scalable number is based on at least a current read rate and a current latency of a link to access the at least one file.

  • Patent number: 8214334
    Abstract: Systems and methods are provided for scanning files and directories in a distributed file system on a network of nodes. The nodes include metadata with attribute information corresponding to files and directories distributed on the nodes. In one embodiment, the files and directories are scanned by commanding the nodes to search their respective metadata for a selected attribute. At least two of the nodes are capable of searching their respective metadata in parallel. In one embodiment, the distributed file system commands the nodes to search for metadata data structures having location information corresponding to a failed device on the network. The metadata data structures identified in the search may then be used to reconstruct lost data that was stored on the failed device.

  • Patent number: 8112395
    Abstract: The intelligent distributed file system enables the storing of file data among a plurality of smart storage units which are accessed as a single file system. The intelligent distributed file system utilizes a metadata data structure to track and manage detailed information about each file, including, for example, the device and block locations of the file's data blocks, to permit different levels of replication and/or redundancy within a single file system, to facilitate the change of redundancy parameters, to provide high-level protection for metadata, to replicate and move data in real-time, and so forth.

  • Patent number: 7937421
    Abstract: Systems and methods for restriping files distributed among a set of smart storage units, wherein data blocks for a particular stripe do not typically need to be located at any particular location on the storage units, wherein data can be typically restriped among the smart storage units with minimal data movement, and wherein data is typically protected and recoverable even if a system failure occurs during the restriping process.
