摘要： A versioned file system comprises a set of structured data representations, such as XML. Each structured data representation corresponds to a “version,” and each version comprises a tree of write-once objects rooted at a root directory manifest. Each version in the versioned file system has associated therewith a “borrow window.” When it is desired to reconstruct the file system to a point in time (or, more generally, a given state), i.e., to perform a “restore,” it is only required to walk (use) a single structured data representation (a tree). During a restore, metadata is pulled back from the cloud first, so users can see the existence of needed files immediately. The remainder of the data is then pulled back from the cloud if/when the user goes to open the file. As a result, the entire file system (or any portion thereof) can be restored to a previous time nearly instantaneously. A “fast” restore is performed if an object being restored exists within a “borrow window” of the version from which the system is restoring.

摘要： An archive cluster application runs across a redundant array of independent nodes. Each node runs an archive cluster application instance comprising a set of software processes: a request manager, a storage manager, a metadata manager, and a policy manager. The request manager manages requests for data, the storage manager manages data read/write functions, and the metadata manager facilitates metadata transactions and recovery. The policy manager implements policies, which are operations that determine the behavior of an “archive object” within the cluster. The archive cluster application provides object-based storage. It associates metadata and policies with the raw archived data, which together comprise an archive object. Object policies govern the object's behavior in the archive. The archive manages itself independently of client applications, acting automatically to ensure that object policies are valid.

摘要： An archive cluster application runs in a distributed manner across a redundant array of independent nodes. Each node preferably runs a complete archive cluster application instance. A given nodes provides a data repository, which stores up to a large amount (e.g., a terabyte) of data, while also acting as a portal that enables access to archive files. Each symmetric node has a set of software processes, e.g., a request manager, a storage manager, a metadata manager, and a policy manager. The request manager manages requests to the node for data (i.e., file data), the storage manager manages data read/write functions from a disk associated with the node, and the metadata manager facilitates metadata transactions and recovery across the distributed database. The policy manager implements one or more policies, which are operations that determine the behavior of an “archive object” within the cluster. The archive cluster application provides object-based storage. Preferably, the application permanently associates metadata and policies with the raw archived data, which together comprise an archive object. Object policies govern the object's behavior in the archive. As a result, the archive manages itself independently of client applications, acting automatically to ensure that all object policies are valid.

摘要： A drill/driver (eg. an electric drill) with a screwdriver attachment, and a method of controlling the drill/driver, are described. A control circuit (30) controls the speed of rotation of the motor (38, 39) through a time delay circuit (42) and a triac (41). The control circuit (30) uses the time delay information and information inputted from a rotational speed sensor (43) to monitor the current in the motor or a parameter related at least in part to current in the motor. When a change corresponding to an increase in the rate of change of current in the motor is detected, the control circuit (30) stops the motor to provide an automatic torque control feature for a screwdriving operation.

摘要： A method of data sharing among multiple entities is provided. Each entity exports to a data store a structured data representation comprising a versioned file system local to that entity. The method begins by forming a sharing group that includes two or more entities. Sharing of the structured data representations by members of the sharing group is enabled. The filers use a single distributed lock to protect each version of the file system. This lock is managed to allow each filer access to the shared file system volume to create its new version. To share a fully-versioned file system, asynchronous updates at each of the filers is permitted, and each node is then allowed to “push” its individual changes to the store to form the next version of the file system. A mechanism also may be used to reduce the period during which filers in the group operate under lock.

摘要： A multi-function hand-held power tool includes an electric motor for driving a tool holder and control means for energizing the motor in accordance with a selected combination of operating conditions under which the tool is to be used. Located on the housing of the tool is a keyboard for inputting to the control means information to define the selected combinations of conditions. The keyboard has a first single key for selecting a tool function, for example drilling, from a defined range of tool functions, a second single key from selecting a required workpiece material for example wood, from a defined range of workpiece materials, and two further keys for selecting, from a defined range, another parameter, for example drill size, appropriate to the selected tool function. A visual display also located on the tool housing is energizable to show symbols indicative of the selected combination of operating conditions.

摘要： A versioned file system comprises a set of structured data representations, such as XML. Each structured data representation corresponds to a “version,” and each version comprises a tree of write-once objects rooted at a root directory manifest. Each version in the versioned file system has associated therewith a “borrow window.” When it is desired to reconstruct the file system to a point in time (or, more generally, a given state), i.e., to perform a “restore,” it is only required to walk (use) a single structured data representation (a tree).

As a result, the entire file system (or any portion thereof) can be restored to a previous time nearly instantaneously. A “fast” restore is performed if an object being restored exists within a “borrow window” of the version from which the system is restoring. A version is pruned from the versioned file system by deleting all objects in the tree (associated with the version) that, at the time of pruning: (i) are not being lent to any other version within the borrow window of the version being pruned, and (ii) are not referenced in any other version whose borrow window is sufficiently large enough such that an object in the version could have been restored from that other version.
