  • Publication number: 20210049962
    Abstract: An apparatus receives current image frame data and data relating to at least one previous image frame for an electronic display. One or more parameters related to hysteresis of transistors in the electronic display are sensed. A correlation device, such as a look-up table, receives the sensed parameter or parameters and the data relating to one or more image frames, and uses this information, at least in part, to output an appropriate compensation signal for the current image frame data. The compensated current image frame data may then be supplied to the electronic display to reduce or eliminate the effects of hysteresis on the displayed image.

  • Publication number: 20200365082
    Abstract: A current-voltage (IV) relationship of a pixel having a diode is initially determined. A first voltage is determined that does not cause the diode to emit light, and a first current across the diode is sensed by applying the first voltage. A predetermined current is determined based on the first voltage and the IV relationship. A ratio is determined based on the first current, a target current, and the predetermined current. A ratio voltage is determined by applying the ratio to a predetermined target voltage. If the first current is less than the predetermined current, then the ratio voltage is applied to supply a target current to the diode. If the first current is greater than the predetermined current, then a second voltage is determined by averaging the first test voltage and the ratio voltage, and the second voltage is applied to supply the target current to the diode.

  • Patent number: 10831720
    Abstract: Methods, systems, and computer programs are presented for providing file system functions on a cloud storage system based on blob storage. A cloud storage system comprises storage clusters, and each storage cluster comprises a plurality of storage nodes (each including a partition layer that stores data in blobs organized within containers, and a stream layer for streaming blob data), a hierarchical namespace service for implementing file system functions on the data stored in the blobs and, a front end layer for processing user requests to access and manage data stored on the blobs. The file system functions include flat namespace functions and hierarchical namespace functions. Further, the front end layer accesses the partition layer to access the blobs based on addresses of blobs and accesses the hierarchical namespace service to identify the blobs.

  • Patent number: 10817498
    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: 20200336455
    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.

  • Patent number: 10789217
    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.

  • Patent number: 10768173
    Abstract: Multivalent binding compositions including a particle-nucleotide conjugate having a plurality of copies of a nucleotide attached to the particle are described. The multivalent binding compositions allow one to localize detectable signals to active regions of biochemical interaction, e.g., sites of protein-protein interaction, protein-nucleic acid interaction, nucleic acid hybridization, or enzymatic reaction, and can be used to identify sites of base incorporation in elongating nucleic acid chains during polymerase reactions and to provide improved base discrimination for sequencing and array based applications.
