  • Patent number: 9026490
    Abstract: A technique for synchronizing a datum between a plurality of stores, wherein a version history is associated with the datum in each store. The version history has one or more entries, and each entry has an identifier and a value. The identifier identifies a store that has modified the datum, and indicates a number of modifications to the datum. When synchronizing the datum between stores, the version histories of the datum are compared to determine whether one version history is subordinate to another version history. The datum having the subordinate version history is then replaced with the datum having the dominant version history. Conflict resolution is required if the version histories are not identical, if the version histories do not have the same identifiers, and if one version history does not contain all of the identifiers with equal or greater values of those in the other version history.

  • Patent number: 8621109
    Abstract: Synchronization of two or more items can be optimized through the use of parallel execution of synchronization tasks and adaptable processing that monitors and adjusts for system loading. Two or more synchronization tasks required to be performed for an item can, if not inherently serial in nature, be performed in parallel, optimizing synchronization of the item. Even if multiple synchronization tasks required for one item must be serially executed, e.g., download the item prior to translating the item, these synchronization tasks can be executed in parallel for different items, optimizing a download request involving two or more items. Moreover, multiple threads for one or more synchronization tasks can be concurrently executed when supportable by the current operating system resources. Rules can be established to ensure synchronization activity is not degraded by the overextension of system resources.

  • Patent number: 8620366
    Abstract: The present invention relates to a method of data uplink synchronization between a mobile terminal and a server. The server modifies the stored address book data one item by one item. The present invention also relates to a method of data downlink synchronization between a mobile terminal and a server. Before the server sends address book data to the mobile terminal requesting the downlink synchronization, it performs item-by-item adaptation of the address book data according to the item's attribute and parameter supported by the mobile terminal. The present invention relates to another method of data downlink synchronization between a mobile terminal and a server. The mobile terminal, according to the received address book data, modifies the stored address book one item by one item.

  • Patent number: 8615487
    Abstract: In one embodiment, information content files, such as text files, image files, XML files and the like, that provide information related to an identifier bearing item, such as a consumer item with a barcode, are stored on a data storage device such as network server. Identifier data entries, such as UPC data, are associated with file data entries, such as file names, in a database. General file access information that is used in accessing the information content files is stored on a terminal. In operation an identifier is read by the terminal and is used to extract one of the file data entries from the database based on database communication information stored on the terminal. The file data entry in combination with the general file access information is used to establish communication with the data storage device and to extract one of the information content files.

  • Patent number: 8606947
    Abstract: The invention provides a mechanism for a transaction coordinator to indicate to a transaction participant that it supports a heuristic outcome, where a course of action has occurred which means that the transaction participant is unable to honor a transactional prior commitment to the transaction coordinator. The mechanism is such that a transaction participant that is incapable of communicating a heuristic outcome may ignore any such indication. A transaction participant may be incapable because it does not understand the concept of a heuristic outcome at all or because it does not have the ability to inform the transaction coordinator that a heuristic outcome has occurred.

  • Patent number: 8566365
    Abstract: A first collection of content that includes digital assets is maintained on a host computer. Based on a determination that a portable media device becomes connected to a client computer that is separate from the host computer and that interacts with the host computer, initiation of a synchronization of the first collection of content resident on the host computer with a second collection of content on the portable media device is automatically triggered. The synchronization of the first collection with the second collection includes a transfer of at least one of the digital assets from the host computer to the client computer to the portable media device and is triggered and conditioned upon the determination that the portable media device has become connected to the client computer.

  • Patent number: 8510324
    Abstract: A method is provided for efficiently transferring records related to places of interest between two communicating vehicles in a V2V system without initially having to transfer full text records. A determination is made as to whether information stored in a memory of the vehicle is redundant with the respect to the other vehicle. A query request is transmitted from a first vehicle to a second vehicle containing specifics as to what records the first vehicle is seeking. Data satisfying the query request represented by global unique index numbers is hashed to determine the similarity between the data of the two communicating vehicles. The similarity is used to determine whether a full filtered set of global unique index numbers should be transferred to the second vehicle for determining which records are not duplicate records. Thereafter, the second vehicle wirelessly transmits to the first vehicle the non-overlapping data that satisfies the query request.

  • Patent number: 8489549
    Abstract: A method of resolving conflicts between revisions to a distributed virtual file system is implemented at a computing device that is communicatively connected to a plurality of storage devices. The virtual file system at the computing device has a first revision of the virtual file system. Upon receipt of a request to synchronize the first revision of the virtual file system with the storage devices, the computing device retrieves one or more blocks from the storage devices, which are associated with a second revision of the virtual file system. The computing device then merges a first component of the first revision with a corresponding component of the second revision if a first predefined condition is met or identifies a second component of the first revision as being conflicted with a corresponding component of the second revision if a second predefined set of conditions is met.
