207 results about "Fluid intake" patented technology

A power plant extracts energy from a free flowing motive fluid by means of a turbine mounted on a gimbal. The shroud element of the fluid intake has external rudders, in conjunction with the gimbal mounting, enabling the enclosed turbine to instantaneously respond to changes in the direction of the free flowing motive fluid thus ensuring the face area of the intake is always physically orthogonal to the direction of the motive fluid streamlines. The shroud element may also be buoyant so as to optimally extract energy from an upper non-turbulent and higher velocity layer of the free flowing motive fluid. To function within an inherently unsteady source of energy, the preferred embodiment of the turbine is coupled to a DC generator which may further be coupled to a voltage and current regulating circuit which either charges a battery, performs electrolysis of water to produce hydrogen fuel, or is further coupled to a DC motor coupled to an AC generator. Alternatively an AC induction generator may be coupled to the turbine. Other mechanical, electrical, electronic, or electromechanical features may optionally be implemented to perform such tasks as adaptively locating the turbine in the maximum velocity flow, adapting internal vane and runner blade pitches for various flow rates and loads, keeping the intake free of obstructions, preventing loss of aquatic life, controlling and communicating the state of charge of the battery, or gauging and controlling the electrolysis process and communicating the fullness of the hydrogen gas output tanks.

The present invention provides an improved disposable article for the absorption and containment of urine or other body exudates, for example a diaper, training pants or an adult incontinence article, that has a high fecal fluid intake rate as measured by the Fecal Fluid Intake Test.

An apparatus comprising first and second fluid intakes, a pump, and a sample chamber, may be positioned in a borehole penetrating a subterranean formation. A method of use thereof may comprise drawing fluid from the subterranean formation and into the first and second fluid intakes using the pump, discharging into the borehole at least a portion of the fluid drawn into the second fluid intake, and selectively diverting at least a portion of the fluid drawn into the first fluid intake to the sample chamber.

An air distribution support surface product includes a vapor permeable material such as a sheet of breathable material, a fluid resistant material, such as a sheet of waterproof material and an intermediate fluid passing material interposed between the vapor permeable material and the fluid resistant material to form a plurality of chambers. One of the chambers serves as a type of fluid retention chamber and another chamber serves as a type of fluid loss chamber. A fluid intake opening may be provided to allow fluid, such as air, to inflate the chambers. In one example, both of the chambers share the intermediate fluid passing material. As such, the fluid retention chamber is formed by the fluid resistant material and the intermediate fluid passing material. The fluid loss chamber is formed by the vapor permeable material and the intermediate fluid passing material.

An electric submersible pump (ESP) assembly comprises an integrated sub-assembly encased within a shroud. The integrated sub-assembly comprises a well fluid intake having a shroud hanger formed in an upper portion thereof, a seal section having a motor head formed in a lower portion thereof, and an electrical conduit extending between the shroud hanger and the motor head. The intake has a plurality of fluid entry slots positioned a select distance from the shroud hanger in order to minimize the space for the accumulation of gas within the shroud. The electrical conduit sealingly extends through the shroud hanger to a receptacle located on an upper portion thereof. Conductors are encased within the conduit and are connected between the receptacle and the motor head. The conduit prevents the conductors from being affected by reservoir fluid and pressures.

A method and apparatus for filtering a large volume fluid intake system using a modular immersed-filtration array that can be easily scaled for use in a wide variety of immersion filtering applications. The immersed-filtration array is composed of a plurality of individual filtration modules. Each filtration module has a mating end that allows the module to be coupled with a base unit or plenum via a common interface port located on the base unit. The array can be scaled in a plurality of ways.

A livestock identification system / method configured to identify individual animals from a pool of livestock is disclosed. The system / method utilizes images of individual animals and determines the identity of a specific animal based on markers extracted from the image of the animal. These markers may then be used to characterize the state of the animal as to weight, health, and other parameters. The system is configured to log these parameters in a temporal database that may be used to determine historical activity of the animal, including but not limited to activity relating to food and / or fluid intake. This historical record in conjunction with analysis of the animal state parameters is used to determine the animal health status and may also be used to determine whether the animal is ready for harvesting.
