摘要:
Embodiments of the present invention provide techniques for distributing the reconstruction process of a failed storage device in an array of storage devices to storage systems in a storage system cluster (cluster). The inventive technique includes a storage system securing the array, decomposing the reconstruction process into a number of tasks, distributing each task to other storage system in the cluster, and reconstructing data using results of the tasks performed by the other storage systems.

Methods and systems for optimizing queries in a multi-tenant store are described. In one embodiment, such a method includes retrieving data from a multi-tenant database system having a relational data store and a non-relational data store, receiving a request specifying data to be retrieved, retrieving one or more locations of the data to be retrieved, generating a database query based on the request, in which the database query specifies a plurality of data elements to be retrieved, the plurality of data elements including one or more data elements residing within the non-relational data store and one or more other data elements residing within the relational data store, generating an optimized database query having an optimized query syntax that is distinct from a query syntax of the database query, and executing the optimized database query against the multi-tenant database system to retrieve the data.

Methods and systems for performing cross store joins in a multi-tenant store are described. In one embodiment, such a method includes retrieving data from a multi-tenant database system having a relational data store and a non-relational data store, receiving a request specifying data to be retrieved from the multi-tenant database system, retrieving, based on the request, one or more locations of the data to be retrieved, generating a database query based on the request, in which the database query specifies a plurality of data elements to be retrieved, the plurality of data elements including one or more data elements residing within the non-relational data store and one or more other data elements residing within the relational data store, and executing the database query against the multi-tenant database system to retrieve the data.

A surgical tissue retrieval instrument has a collapsible pouch at the distal end of an elongated pusher rod that is introduced into a patient's abdomen through a cannula. The instrument includes a two-jaw fork that forms a loop when in an unconstrained configuration and that supports the pouch. Deployment and operation of the fork and the pouch are controlled by a toggle means. The two jaws and the toggle means are slid in a hem surrounding the opening of the pouch when the device is assembled. An especially advantageous embodiment features two jaws of unequal length.

The present disclosure is directed to a medical device or article that reduces the ability of the Keith needle to unintentionally fall out of the barrel, improves the ability of the Keith needle to track on axis, or both. In one aspect, the disclosure is directed toward a medical device suitable for use in implant surgery. The medical device includes a Furlow insertion tool with a barrel having a bore. The Furlow tool further includes an obturator adapted for slidable insertion into the bore. The medical device further includes a Keith needle adapted for slidable insertion into the bore. The Keith needle is adapted to yieldably fit against at least one of the barrel and the obturator when the Keith needle is disposed within the bore. In another aspect, the present disclosure is directed toward a Keith needle adapted for use with a Furlow insertion tool. The Furlow insertion tool including a barrel and an obturator. The barrel includes a bore having a diameter such that the Keith needle is adapted to be disposed within the bore. The Keith needle includes a blunt portion adapted to contact the obturator, a tip portion including a sharp end, and an interference portion operably coupled to the blunt portion and the tip portion. The interference portion has an operating thickness of at least the diameter of the bore to yeildably fit the Keith needle against the barrel when the Keith needle is disposed within the bore.

A method and system for hierarchical prioritization and execution of call completion services are provided. When a caller applies for a call completion service, the caller is identified and assigned a priority from among different priorities such as high priority or regular priority. Thereafter, attempts to execute call completion services are performed hierarchically by launching call completion services for callers having a higher priority before similar attempts are performed for callers of a lower priority. Hence, call completion services are handled according to the priority assigned to the callers rather than the order in which each caller applied for a call completion service.

The present embodiments provide methods, apparatuses, and systems for use in maintaining data quality upon conversion to a different data format. Some embodiments provide methods that receive media data in a first format, initiate a first conversion of the media data at the first format to a second converted format, identify parameters dictating the conversion to the second converted format, record the parameters, and distribute the recorded parameters to remote systems such that the parameters at least in part control the remote systems during a conversion of the media data to the second converted format.
摘要:
A split MAC layer system is disclosed. The split MAC layer system comprises an upper MAC portion wherein the upper MAC portion is dependent on a MAC protocol, a lower MAC portion wherein the lower MAC portion is independent of the MAC protocol, and wherein the upper MAC portion communicates information to the lower MAC portion using an information structure including an action pointer.
