The criteria includes at least one of the parameter of the fluid to be output, an input signal specifying sensors to be selected, a predetermined configuration based on the parameter to be determined, and in response to a previously determined parameter of the fluid.

摘要： An apparatus for measuring at least one parameter associated with a fluid flowing within a pipe includes a spatial array of pressure sensors disposed at different axial locations x1. . . xN along the pipe. Each of the pressure sensors provides a pressure signal P(t) indicative of unsteady pressure within the pipe at a corresponding axial location of the pipe. A signal processor receives the pressure signals from each of the pressure sensors and determines the parameter of the fluid using pressure signals from selected ones of the pressure sensors. By selecting different pressure sensors, the signal processor can configure the array to meet different criteria. In one embodiment, the array of pressure sensors may be formed on a single sheet of polyvinylidene fluoride (PVDF) that is wrapped around at least a portion of an outer surface of the pipe. This arrangement allows a large number of pressure sensors to be quickly and economically installed.

摘要： A bone plate system is provided. The system includes two or more fastener locks stacked on top of each other and located between two holes in a plate adapted to receive bone fasteners. An actuator is provided between the locks. As the actuator is advanced, the locks are moved sequentially into position, firstly, to prevent one or more bone fasteners from backing out of the plate while permitting the fasteners to angulate and, secondly, to lock the angulation of the bone fasteners while still providing back out protection in situ. An expandable bone plate having a top plate interconnected to a bottom plate by a rack and pinion is provided. The rotation of the pinion with a driver lengthens or shortens the plate incrementally for custom length adjustment. The length is fixed in position with the simple removal of the driver and no further step is required to lock the plate length.

摘要： An improved misting bottle and fan apparatus capable of both convective cooling and evaporative cooling independent of either other. The operator can select to have the convective cooling effects of air being blown over the operator. The operator can select to have the evaporative cooling effects of pressurized fluid forced through a small orifice showered down at the operator. In the alternative, the operator is able to select both style of cooling using this device. The positioning and shape of the atomizing device in relation to the forced air is unique as well as the shaping of the air flow optimizes the cooling effects. Location of the atomizing device is proscribed as to prevent the occurrence of drips and runs commonly associated with misting fans.

摘要： Accelerated sub-string searches on large data sets can be performed using filtering processes that can improve or optimize run time performance. A first filtering process can include partitioning a binary tree into sections to enable an exact search to replace a substring search for part of the binary tree and for part of the binary tree to be potentially excluded from substring searching. A second filtering process can include comparing count representations of entries in the binary tree and of a received input string to potentially further exclude entries from substring searching.
摘要翻译：可以使用可以提高或优化运行时性能的过滤过程来执行对大型数据集的加速子字符串搜索。第一个过滤过程可以包括将二进制树划分为多个部分，以便能够精确搜索替换二叉树的一部分的子字符串搜索，以及二进制树的一部分可能被排除在子串搜索之外。第二滤波处理可以包括比较二叉树中的条目和接收到的输入字符串的计数表示，以潜在地进一步从子串搜索中排除条目。
