摘要:
A system and method of distributing traffic across a computer network is provided using a relay apparatus. A relay apparatus includes an interface to a communication network, a data store, and a processor. The data store includes data elements associating a first network address of a server to a second network address of the server. The processor is configured to receive a request corresponding to a data element in the data store, use the data element to determine a corresponding server, and forward the request to the server in a manner such that any response to the forwarded request is sent to the relay apparatus.
摘要:
This invention relates generally to a stent comprising a plurality of struts and a plurality of projecting elements integral with the struts. At least some of the struts and some of the projecting elements comprise a biologically active material. The struts are configured in a tubular shape or tubular sidewall having two ends. One end of at least one of the projecting elements defines an end of the stent when the stent is expanded. The invention is also directed to a method for delivering the biologically active material to body tissue of a patient by inserting such an expandable stent into body of the patient. The invention is further directed to a system comprising the expandable stent and a balloon catheter for expanding the stent.
摘要:
A stent assembly comprises a substantially tubular, first stent body and a second stent body. In an undeployed state the second stent body is at least partially positioned within the lumen of the first stent body. The first stent body define a first side branch opening in fluid communication with the lumen. The second stent body comprises a plurality of side branch projecting members. The projecting members define a second side branch opening in fluid communication with the first side branch opening and the lumen. In a deployed state the projecting members extend through the first side branch opening and form an oblique angle relative to the longitudinal axis of the first stent body.
摘要:
A method and a system is disclosed for managing distribution of computer-executable program threads between a plurality of central processing units (CPUs) administered by an operating system in a multi-CPU computer system having a plurality of memory caches shared amongst the CPUs. The method includes assigning the CPUs to a plurality of CPU-groups of a predetermined group-size, selecting a CPU-group form the CPU-groups, setting a predetermined threshold for the selected CPU-group, and affinitizing a program thread to the selected CPU-group based on the predetermined threshold wherein the operating system distributes the program threads among the CPU-groups based on the affinitizing. In this way, the memory access time delays associated with the transfer of data amongst the CPU-groups can be advantageously reduced while the ability to more effectively utilize the total number of available CPUs in the processing of the program threads is advantageously increased.
摘要:
In one aspect, a method of creating a virtualized computer environment that represents a real world computer environment is provided. The real world computer environment comprises a plurality of components, the plurality of components comprising a plurality of computer devices and at least one network device that implements a network that interconnects the plurality of computer devices, the real world computer environment comprising at least one security facility that implements at least one security function in the real world computer environment. The method comprises acts of including in the virtualized computer environment a virtualized representation of at least one of the plurality of computer devices in the real world computer environment and implementing the at least one security function in the virtualized computer environment. In another aspect, a virtualized representation of the at least one network device is provided. In another aspect, software is executed in the virtual computer environment.
摘要:
Foldable boom inner wings are attached to a boom center frame through a rocker attached to a breakaway hydraulic cylinder pressurized to full stroke and connected to an accumulator. When a wing impacts an object, the impact load is transmitted through the fold cylinder and rocker into the breakaway cylinder. As the breakaway cylinder retracts to allow the wing to pivot, pressure builds in the system in three stages. First pressure builds along an accumulator pressure curve until a relief valve in the hydraulic system actives to initiate the second stage wherein oil is dumped through the relief valve. Thereafter, pressure is again allowed to build along the same accumulator curve to absorb impact hydraulically before the cylinder reaches full stroke. The staged pressure buildup prevents boom momentum from gaining and loads from increasing above the strength of the overall structure.
摘要:
In one aspect, the invention features a method including contacting a first gas to an anode of a fuel cell, and contacting a second gas to a cathode of the fuel cell. The first gas is capable of interacting with the anode to form protons, and the second gas is substantially free of a gas capable of being reduced by the cathode.
