    • An intravascular catheter, such as a balloon catheter, and a method for use thereof, the catheter comprising an elongate shaft having an inflation lumen extending therethrough, an implement, such as a dilation balloon, connected to and located at the distal portion of the shaft and communicating with the lumen, a small profile core wire extending through at least the dilation balloon and having a distal portion that extends distally from the dilation balloon through a distal core wire opening located distally of the balloon, and further in which the core wire is movable relative to the elongate shaft to allow withdrawal of the elongate shaft and the balloon while leaving the core wire positioned intravascularly, and a tip member connected to the core wire in a region thereof distal of the location at which the core wire extends distally of the core wire opening, the tip member having a profile larger than the opening. Also, a manifold is provided adapted to both form a fluid seal around a guide wire received in a port and spatially fix the position of the guide wire in the manifold. Also, the manifold automatically closes a fluid port upon disconnection of a source of fluid from the fluid port.

    • A downhole piston accumulator system is disclosed, such as for a formation tester. The soft piston of the system is designed to withstand high pressure downhole fluids in small volume cylinders, the fluid being collected for optical fluid identification or other analyses. The temperature range of the fluid may vary widely, which can be accommodated by the soft piston. Sealing components on the soft piston include additional materials for sealing the soft piston and otherwise helping to accommodate the wide ranging pressures and temperatures. The piston container or cylinder is designed to properly capture the piston and accommodate piston movement. The piston accumulator system allows an outer or exterior position sensor to detect piston movement, such as by a magnetic sensor.
    • 公开了一种井下活塞蓄能器系统,例如用于地层测试仪。 系统的软活塞设计用于承受小体积气瓶中的高压井下流体,收集流体用于光学流体识别或其他分析。 流体的温度范围可能变化很大,这可以通过软活塞来适应。 软活塞上的密封部件包括用于密封软活塞的其他材料,否则有助于适应宽范围的压力和温度。 活塞容器或气缸被设计成适当地捕获活塞并适应活塞运动。 活塞蓄能器系统允许外部或外部位置传感器检测活塞运动,例如通过磁性传感器。

    • Apparatus, systems, and methods may operate to receive incident energy within a chamber defining a first part of an interaction volume that attenuates the incident energy as a function of path length to provide attenuated energy. Additional activity may include simultaneously transforming the attenuated energy characterized by a substantially exponential intensity function into resultant energy characterized by a substantially polynomial intensity function. The transformation may be accomplished using an interacted energy transformation element that defines a second part of the interaction volume, the transformation element operating to intercept the attenuated energy along a plurality of path lengths. Other activity may include transmitting the resultant energy to a receiver. Additional apparatus, systems, and methods are disclosed.
