International Classification:

G01N 11/00

US Classification:

73 5441, 73 5402, 73 5424, 73 5425

Abstract:

A method and apparatus for providing, e. g. , identifying or determining, at least one parameter of a fluid moving through a fluid channel using a vibrating wire in contact with the fluid moving through the fluid channel that is clamped under tension. The vibrating wire is actuated by an actuating device capable of displacing the vibrating wire from an initial position. An interpretation element further is utilized to provide a parameter of the fluid moving through the fluid channel based upon data from the vibrating wire following actuation by the actuation element.

International Classification:

E21B 47/01

US Classification:

16625001, 166 66, 1662424

Abstract:

Protective barriers for small devices, such as sensors, actuators, flow control devices, among others, protect the devices from erosive and/or corrosive fluids, for example, formation fluids under harsh downhole conditions. The protective barriers include protective coatings and fluid diverting structures in the fluid flow which facilitate use of the small devices in high temperature-high pressure applications with erosive and/or corrosive fluids that are often found in downhole environments.

International Classification:

G01N 11/08

US Classification:

73 5409

Abstract:

A micro-fluidic device and methods for measuring one or more rheologic properties of a fluid. The micro-fluidic device includes a substrate and at least one cover bonded to a surface of the substrate with a fluid channel formed in at least one of the cover or the substrate. Further, the micro-fluidic device includes a first differential pressure gauge that can have a first differential pressure sensor in fluid communication with both a first pressure site and a second pressure site. Further still, the micro-fluidic device includes the first pressure site and the second pressure site that can be spaced apart by a first section of the fluid channel. Also, the micro-fluidic device includes a data processor communicatively coupled to the first differential pressure sensor, so as to receive data generated by the first differential pressure sensor.

US Classification:

382118, 382173

Abstract:

Virtual environments are presented on displays along with multimedia programs to permit viewers to participate in a social interactive television environment. The virtual environments include avatars that are created and maintained in part using continually updated animation data that may be captured from cameras that monitor viewing areas in a plurality of sites. User input from the viewers may be processed in determining which viewers are presented in instances of the virtual environment. Continually updating the animation data results in avatars accurately depicting a viewer's facial expressions and other characteristics. Presence data may be collected and used to determine when to capture background images from a viewing area that may later be subtracted during the capture of animation data. Speech recognition technology may be employed to provide callouts within a virtual environment.

US Classification:

422 681, 436121, 436164, 436 25

Abstract:

Methods and related apparatuses and mixtures are described for detecting hydrogen sulfide in a formation fluid downhole. A detection mixture is combined with the formation fluid downhole. The detection mixture includes metal ions for reacting with hydrogen sulfide forming a metal sulfide, and charged nanoparticles sized so as to inhibit significant aggregation of the metal sulfide so as to enable spectroscopic detection of the metal sulfide downhole. The combined mixture and formation fluid is then spectroscopically interrogated so as to detect the presence of the metal sulfide thereby indicating the presence of hydrogen sulfide in the formation fluid. The mixture also includes chelating ligands for sustaining thermal endurance of the mixture under downhole conditions.
