摘要： Various apparatus or methods are arranged to operate a tool in a wellbore, where the tool has a number of acoustic sensors. Scanning images obtained by the tool sensors along the borehole can be combined to increase the contrast of leak location with respect to background noise. A sequence of beamformed images, generated from signals captured by the tool as it moves over a range of depths of the wellbore, can be acquired. Each beamformed image may overlap at least one other beamformed image of the sequence. The beamformed images can be processed and the processed beamformed images can be combined, forming a stitched image. Additional apparatus, systems, and methods operable in providing stitched images can operate in a variety of applications.

摘要： Disclosed are tools, systems, and methods for detecting one or more underground acoustic sources and localizing them in depth and radial distance from a wellbore, for example, for the purpose of finding underground fluid flows, such as may result from leaks in the well barriers. In various embodiments, acoustic-source detection and localization are accomplished with an array of at least three acoustic sensors disposed in the wellbore, in conjunction with array signal processing.

摘要： A protective circuit compares at least two different signals and asserts a control node toward respective logic states accordingly. At least one of the signals is derived from a voltage on a power rail within a computer or other device. A switching element passes or isolates an enable signal based on the logic state of the control node, enabling or preventing operation of a power supply, accordingly. Central processing units (CPUs) or other elements are protected against electrically caused damage in the event that a fault is detected by the protective circuit.

摘要： Inverse search systems and methods operate on identifiers of content items in a corpus such as the World Wide Web In an inverse search, the user submits a query that includes an identifier of a target content item in the corpus and receives information (metadata) about the target content item being returned to the user. Many types of metadata can be returned, including ratings or other metadata related to the target content item obtained from users, popularity data specific to the target content item, information about previously submitted forward search queries that led to the target content item being identified as a hit, and metadata extracted from the target content item.

摘要： A system and method is disclosed for failure recovery and communications in a shared storage system. The shared storage system includes at least two host nodes, each of which includes two ports. Each of the ports of each of the nodes is coupled to input ports of a storage enclosure. The input ports of the storage enclosures are in turn coupled to one another to form communications links between each of the host nodes. When the communications links between the host nodes fail, the host nodes are able to pass configuration information to each other by saving configuration information to a central location in a shared storage, such as a dedicated location in one of the storage drives of the storage enclosure that is directly coupled to both host nodes. The host nodes are able to force their peer nodes to read configuration changes before accessing possibly corrupted data from a previous configuration.

摘要： A system and method for recovering from a server failure in a computer network, wherein the network contains several stand-alone, non-clustered, servers, and a cluster, wherein a clustered server also serves as the spare server, is disclosed. This cluster will have one standby recovery group for each non-clustered server in the computer network. Each recovery group contains the IP address and network name of the associated stand-alone server. The cluster monitors the health of the stand-alone servers, preferably through the use of a heartbeat mechanism. If the cluster detects a failure, it will reassign the LUNs owned by the failing server to the cluster. After the cluster has reassigned the LUNs, it will activate the recovery group containing the IP address and network name of the failing server. Subsequently, the cluster will assume the identity of the failing server and serve its users, until the failing server is repaired or replaced.
