摘要:
A solution for rapid evaluation of numerically large complex rules governing network and application transactions includes, at a network device, receiving network transaction record comprising a plurality of elements that characterize a network transaction, creating a hash of a result of concatenating the plurality of elements, and if the hash is found in a hash table comprising, for each network transaction rule, a hash of the plurality of elements comprising the rule, blocking the network transaction or alerting a network user that a prohibited transaction has occurred.

Embodiments of the disclosure may include a medical device comprising a flexible elongate member including a longitudinal axis and a tool connected to the elongate member at a pivot axis, wherein the tool may be configured to conduct electricity and deliver a fluid, and wherein the tool may be configured to pivot towards either side of the longitudinal axis relative to the elongate member at the pivot axis.
摘要:
A device and related methods of use for guiding a surgical tool. The device may include a mating section for mating with a portion of a guide tube. An elongate structure may extend from the mating section. In addition, the elongate structure may be configured to transition between a collapsed delivery configuration and an expanded deployed configuration.

A cocoa powder composition which, when mixed with bulking sugar, is dispersible in cold liquids and methods of producing and using the same. The cocoa powder composition comprises, on a dry weight basis, 75-95% cocoa powder and 0.5-20% of at least one hydrophilic agent, wherein the cocoa powder is coated with the hydrophilic agent.
摘要:
Methods and apparatus enable reliable and improved isolation between two portions of a bore extending through a casing string disposed in a borehole. A downhole deployment valve (DDV) may provide the isolation utilizing a valve member such as a flapper that is disposed in a housing of the DDV and is designed to close against a seat within the housing. The DDV includes an operating mechanism for opening/closing the DDV. In use, pressure in one portion of a well that is in fluid communication with a well surface may be bled off and open at well surface while maintaining pressure in another portion of the casing string beyond the DDV.

Embodiments of the invention include a system for guiding an instrument. The system may include a frame and a bearing assembly supported by the frame. The bearing assembly may include an outer tubular member supported by the frame and including a proximal end and a distal end. The bearing assembly may also include a bearing at least partially disposed within at least one of the proximal end and the distal end of the outer tubular member. The channel may extend through the outer tubular member and the bearing.

There is provided herein a performance-enhancing composition comprising inorganic nanoparticles dispersed in a polymer selected from the group consisting of polysiloxane, polysilsesquioxane, and mixtures thereof. This composition, when applied to a thin-film transistor, such as a bottom-gate thin-film transistor, as an overcoat or top layer, improves the carrier mobility and current on/off ratio of the thin film transistor. Also provided is the thin-film transistor produced utilizing this process and/or composition.
摘要:
A power distribution system comprising a stack of bus bars having through-hole openings arranged in end portions of each of the bars such that the stack of the bars are connectable to bars of an adjacent stack. One or more connectors pass through the holes in one of the end portions of the bars of the stack. The one or more connectors also pass through holes in one of the end portions of the bars of the adjacent stack. One of the end portions of the bars of the stacks are interleaved with one of the end portions of the bars of the adjacent stack.
