Abstract: A server stores files and manages the synchronization of those files across client devices in accordance with user preferences that may be embodied in change management rules. A first version of a file has been designated to be synchronized across at least a first client and a second client. The first client accesses the first version of the file and creates a first modified version of the file, and the second client accesses the first version of the file and creates a second modified version of the file. When the first and second clients attempt to re-synchronize their respective modified versions of the file, the server determines a preferred version from among the available modified versions of the file according to change management rules. Then, the preferred version is stored by the server and is subsequently served for synchronization across the client devices.

The copy of the copy of the first data entity in the first intra-transactional cache is accessed for further processing of the first data entity by the first client.

Abstract: The invention provides a method for controlling writing of data to a data storage card having a device controller and a storage medium. Particularly, the device controller receives a meta data synchronization disable command and in response, enters a first mode. In the first mode, the device controller does not synchronize meta data related to a data write request to write the data to the storage medium, leaving corresponding unsynchronized meta data. The device controller receives a data write request to write the data, and in response, effects the data write request such that the data is written to the storage medium. However, the meta data related to the data write request is not synchronized to the storage medium. Other aspects provide a corresponding device controller and software/firmware.

Abstract: A content management system synchronizes content items across client computing systems connected by a network. Each client device has a storage allocation for synchronized shared content items. If the storage allocation for shared content items on a client device is exceeded by the request to add or edit a content item such that it is enlarged, or open a large content item remote to the client device, a client application or the host of content management system selects content items to remove from residence on the client device but keep remotely on content management system. Upon removal of the selected content items, the client application creates shadow items, representing the content item but only containing the metadata of the content item. This creates sufficient space for the initial request to be completed while maintaining user access to all synchronized shared content items. The processes of replacing content items with shadow items may be completed while the client device is idle.

Abstract: Test and measurement instrumentation collects time information independently in each clock domain using a device that monotonically changes state with the passage of time according to a local clock domain. The device under test therefore has a unique state for each synchronous time period. The instrumentation periodically samples the devices under test, collects the state of each device, and records the state of the devices in conjunction with any data collected in clock domains that are synchronous with the devices. The periodic samples are transformed into numeric values using an isomorphic or linear model. These values are then fitted to an assumed frequency model that relates the state of devices in otherwise unrelated clock domains.

Abstract: Methods, apparatus, systems, and computer program products are provided for wirelessly synchronizing datasets that are stored on a wireless device and at a network device, such as a network server or database. Present aspects provide for a simplified and efficient synchronization process, whereby synchronization can be completed in a single round-trip of wireless communication between the wireless device and the network device. Single round-trip synchronization provides for less use of network resources, shorter overall synchronization cycle times and lessens the likelihood of wireless network failures, such as call drops or the like, causing the synchronization process to fail. Additionally, simplification and efficiency are further realized by creating a synchronization process that allows the network dataset to be independent of the wireless device datasets, i.e., the network server does not require a full change history nor is the network server required to know the wireless device dataset version.
