    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: 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: 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.
