    摘要： Certain aspects and embodiments of the present invention are directed to a porous medium screen that can be disposed in a wellbore through a fluid-producing formation. The porous medium screen can include a porous medium and a retaining structure. The porous medium can be a material having one or more pores. The one or more pores can be adapted to allow a fluid to flow through the porous medium and to prevent one or more particles from flowing through the porous medium. The retaining structure can be adapted to retain the porous medium in a position circumferentially surrounding a section of a tubing string and to prevent expansion of the porous medium. The retaining structure can include a shroud and one or more stoppers. The shroud can be adapted to circumferentially surround the porous medium. Each stopper can be adapted to circumferentially surround the section of a tubing string at an edge of the porous medium.

    摘要： Fluid flow influencer devices capable of affecting fluid flow for fluid selection are described. Fluid flow influencer devices may affect fluid flowing into a turbulence, such as a vortex, having a structure that is usable to restrict fluid flow in a flow path of a chamber by different amounts based on at least one property of the fluid. The fluid flow control device may be in an autonomous fluid selector, such as a diverter, a vortex-causing device, or a whisker. Fluid properties based on which the flow influencer device can select fluid can include fluid density, fluid velocity, fluid viscosity, and Reynolds number of the fluid flow.

    摘要： An apparatus and method are described for autonomously controlling flow of fluid in a subterranean well, where fluid flow is controlled based on a fluid characteristic, such as viscosity or density, which changes over time. Fluid flows into a vortex assembly where a centrifugal force is imparted to the fluid. A less viscous fluid will have a relatively greater velocity and centrifugal force than a more viscous fluid. The fluid exits the vortex chamber by both a vortex outlet and a peripheral outlet. An autonomous valve element moves between an open position, in which fluid flows freely through the peripheral outlet, and a closed position, in which fluid flow through the peripheral outlet is restricted. The valve element is moved by the centrifugal force of the fluid, such that a fluid having a higher centrifugal force moves the valve element to the closed position, thereby reducing the total fluid flow through the vortex assembly.

    摘要： Apparatus and methods for autonomously controlling fluid flow in a subterranean well are presented, and in particular for providing a fluid diode to create a relatively high resistance to fluid flow in one direction and a relatively low resistance to fluid flowing in the opposite direction. The diode is positioned in a fluid passageway and has opposing high resistance and low resistance entries. In one embodiment, the high resistance entry has a concave, annular surface surrounding an orifice and the low resistance entry has a substantially conical surface. The concave, annular surface of the high resistance entry preferably extends longitudinally beyond the plane of the orifice. In a preferred embodiment, the fluid will flow in eddies adjacent the concave, annular surface.

    摘要： A method and system for controlling multimedia presentation characteristics among a plurality of devices are disclosed. An electronic device (100) is capable of communication (109) with a peripheral device (102) to play back content (107) on the peripheral device (102). The content (107) has an associated a multimedia presentation characteristic signal, for example an audio signal (108). When the electronic device (101) receives a user input request to adjust a system volume, the device is configured to adjust either the associated audio signal or an output volume level of the peripheral device (102). Once this adjustment reaches a threshold, the device is configured to adjust the other of the associated audio signal or the output volume level of the peripheral device (102). The decision of which control to adjust first and which to adjust second can be user defined. The process can be repeated when more than two devices are included in the system.

    摘要： A reconfigurable LNA for increased jammer rejection is disclosed. An exemplary embodiment includes an LNA having a tunable resonant frequency, and a detector configured to output a control signal to tune the resonant frequency of the LNA to increase jammer suppression. An exemplary method includes detecting if a jammer is present, tuning a resonant frequency of an LNA away from the jammer to increase jammer rejection if the jammer is present, and tuning the resonant frequency of the LNA to a selected operating frequency if the jammer is not present.
