  • Patent number: 10537275
    Abstract: A system and a method is provided for assessing motion of a biological tissue of a subject including one or more superficial biological layers and a targeted biological layer. An optical perturbation is introduced within the one or more superficial biological layers but not within the targeted biological layer. A set of optical signal data is acquired preceding, during, or following the optical perturbation and, using the set of optical signal data, a set of optical characteristics is determined that is representative of light transiting the biological layers. Using the set of optical characteristics and a model of the biological layers, a target optical signal consistent with a target biological layer is separated and a movement of the desired biological tissue is determined using the target optical signal.

  • Publication number: 20190392053
    Abstract: Methods, systems, and apparatuses are provided for a storage system that implements a hierarchical namespace service. A storage system includes a plurality of physical nodes and a plurality of sets of virtual nodes. Each set of virtual nodes is managed by a corresponding physical node. Each virtual node is configured to manage a respective set of directory blocks. Each directory block is a respective partition of a storage namespace and is managed by a corresponding single virtual node. Each virtual node maintains a directory block map. The directory block map maps file system object names in a hierarchical namespace to entity block identifiers in the flat namespace for entity blocks (files and folders) stored in directories corresponding to the managed set of directory blocks. Load balancing may be performed by moving virtual nodes between physical nodes, and by splitting directory blocks.

  • Publication number: 20190394162
    Abstract: A service enables a command that refers to a file system object using a hierarchical namespace identifier to be executed against the file system object in a flat namespace. The service selectively distributes the command to one of a plurality of name resolution nodes based on a directory name included in the hierarchical namespace identifier. The identified node resolves the directory name to a flat namespace identifier that is used to execute the command against the flat namespace. After communicating with at least one storage node to resolve a directory name, each name resolution node stores a mapping of the directory name to the corresponding flat namespace identifier in a cache, so that subsequent resolutions of that directory name may be performed more efficiently. Cache entries may be invalidated when an operation occurs that impacts the relevant mapping and/or based on system considerations such as cache expiry.

  • Publication number: 20190370365
    Abstract: Methods, systems, and programs provide for executing distributed transactions in a cloud storage system with a hierarchical namespace. One method includes receiving a request with operations to be executed atomically. Further, nodes are identified for executing the operations, each node having a respective clock and having at least part of a transactions table for controlling updates to entities. Each clock is one of a loosely-synchronized, a strictly-synchronized clock, a logical, or a physical clock. Additionally, the nodes process the operations, which includes setting a commit timestamp (CS) to a value of the clock in the node if the node is a first node in the processing. One node coordinates the transactions, and may be one of the nodes executing transactions. If the clock in the node is less than a current value of the CS, the node waits for the clock to reach the current value of the CS and the CS is updated.

  • Publication number: 20190339873
    Abstract: A cloud storage system includes a processor and a non-transitory computer-readable medium to store blob table management instructions for execution by the processor. The blob table management instructions are configured to manage a plurality of storage requests for a blob stored in a storage stamp as snapshots in a blob table and selectively create a user snapshot of at least one of the snapshots in the blob table. When automatic snapshots are enabled, the blob table management instructions are configured to receive a first request to overwrite the blob. If the first request does not further specify a key of the one of the snapshots in the blob table, the blob table management instructions are configured to add a new snapshot to the blob table and maintain storage of a prior snapshot of the blob for a maximum period.

  • Patent number: 10447607
    Abstract: Methods for dequeue optimizations in queues are performed by systems and apparatuses. The methods optimize dequeue operations using aggregation of expired messages enqueued in a queue and conditional iteration over enqueued messages based on the aggregation to service dequeue commands. Queues utilize page hierarchies such as root pages, index pages, and data pages. The aggregation of expired messages for pages in the queue determines the latest expired time for messages for a given page, and these latest expired times are stored in their respective pages, including data pages, index pages, and root pages, for use in the conditional iteration. The conditional iteration bypasses pages for which a latest expired time for all messages is prior to the current time when servicing dequeue requests for the queue.

  • Publication number: 20190298387
    Abstract: An implant for treatment of a vascular space can form open loops and closed loops in separate cycles to provide balanced stiffness and flexibility. Such an implant provides both stability for retention within the vascular space and conformability for mitigating forces on the vasculature. Such a configuration can also provide proper coverage over an opening to a vascular space into which the implant is delivered, for reducing or eliminating flow into or out of the body cavity and promoting occlusion of the vascular space.
