摘要： A DC voltage distribution system includes at least one load connected in parallel to a first DC power supply via a first distance of wire, and connected in parallel to a second DC power supply via a second distance of wire. The first and second DC power supplies are configured to enter a load sharing mode in which one of the first or second DC power supplies selectively increases its voltage to prevent the other of the first or second DC power supplies from exceeding its power output threshold. The DC power supplies are also configured to enter a load balancing mode in which the DC power supplies set their output voltages to the same value such that a flow of current on the longer of the wire distances is reduced and a flow of current on the shorter of the wire distances is increased.

摘要： Retrievable bridge plug used in oil and gas wells comprises a setting and anchoring mechanism, a locking and releasing mechanism and a sealing and anti-adhering mechanism. The bridge plug in which a self-lock mechanism is placed can be lowered through an coiled tubing or wireline, and provide reliable bi-directional sealing, and can be taken out by a specific tool after setting, in order to be used repeatedly after simple maintenance. By replacing its mandrel, the bridge plug can be refitted into a squeezing bridge plug, a conventional one and a hook-wall bridge plug to be used in a temporary/permanent and selective blocking operation. Also, the bridge plug can be associated with other downhole tools to perform well test, layer protection and snubbing.

摘要： Embodiments of the present invention relate to the use of stamping to form features on a lead frame of a semiconductor device package. In one embodiment, portions of the lead frame such as pins are moved out of the horizontal plane of a diepad by stamping. In certain embodiments, indentations or a complex cross-sectional profile, such as chamfered, may be imparted to portions of the pins and/or diepad by stamping. The complexity offered by such a stamped cross-sectional profile serves to enhance mechanical interlocking of the lead frame within the plastic molding of the package body. Other techniques such as selective electroplating and/or formation of a brown oxide guard band to limit spreading of adhesive material during die attach, may be employed alone or in combination to facilitate fabrication of a package having such stamped features.

摘要： A system for utilizing informed throttling to guarantee quality of service to a plurality of clients includes a server core having a performance analyzer that compares a performance level received by a client to a corresponding contracted service level and determines if the client qualifies as a victim whose received performance level is less than the corresponding contracted service level. The performance analyzer is further configured to identify one or more candidates for throttling in response to an I/O stream receiving insufficient resources by determining if the client qualifies as a candidate whose received performance level is better than the corresponding contracted service level. The server core further includes a scheduler that selectively and dynamically issues a throttling command to the candidate client, and provides a quality of service enforcement point by concurrently monitoring a plurality of I/O streams to candidate clients and concurrently throttling commands to the candidate clients.
