| 20090036817 | IMPLANTABLE FLOW CONNECTOR - An implantable flow connector for fluidically coupling a source tissue-enclosed body space with a destination element, comprising: a conduit having a lumen terminating at an orifice at a first end of the conduit implantable in the source body space through an opening formed in a tissue wall of the source body space, and a second end of the conduit implantable in the destination element through an opening in a surface of the destination element; and a circumferential flange, radially extending from the conduit proximate the conduit first end, configured to be implanted in the source body space adjacent an opening in the tissue wall of the source body space such that the conduit extends through the opening, the flange comprising one or more circumferentially adjacent sections at least one of which has a rigidity that decreases in a radially-increasing direction. | 02-05-2009 |

| 20110037970 | Laser Doppler Velocimeter - A laser Doppler velocimeter is formed using a fiber laser as the lasing medium. Within the velocimeter, all optical signals, transmitted and received, are conveyed by optical fibers. An amplifier amplifies a source laser, which is then transmitted to one or more transceivers. The one or more transceivers, each projecting along a different axis, and each with a single optical fiber input/output interface act as both the transmission device to focus the radiation at a target region, and as the receiving system for collecting reflected radiation. The transceivers each include an amplifier to further amplify the radiation received from the laser source. The one or more transceivers transmit radiation simultaneously to the target region, and may be located remotely from the laser source. The portion of the reflected radiation collected by the receiving system is analyzed to determine the Doppler shift caused by targets at the focal point of the one or more transceivers. | 02-17-2011 |

| 20110216307 | High Density Wind Velocity Data Collection for Wind Turbine - Methods and systems for collecting high-density wind velocity data for the inflow area of a wind turbine are presented. Wind turbines are provided with one or more wind velocity sensors that provide a plurality of wind velocity measurements to the turbine from various ranges and locations across the inflow. Sensors are proximate to the wind turbine. Sensors mounted on the turbine's nacelle work collaboratively to provide the wind velocity measurements. Sensors mounted on the turbine's hub spin with the turbine blades. Spatial and temporal wind mapping provides improved fidelity of data to the wind turbine control system. | 09-08-2011 |

| 20100300967 | BREAKER FLUIDS AND METHODS OF USING THE SAME - A method of cleaning a wellbore drilled with a drilling fluid that forms a filter cake that includes emplacing a breaker fluid into the wellbore, the breaker fluid comprising: an aqueous fluid; a fragmentation agent; and an amphoteric chemotrope; and shutting in the well for a period of time sufficient to initiate breaking of the filter cake is disclosed. | 12-02-2010 |
| 20100307746 | METHODS OF CLEANING WELLBORES AND ANALYZING WELLBORE FLUIDS - A method of analyzing a wellbore fluid that includes treating a wellbore fluid with an emulsifying fluid, the emulsifying fluid comprising: a hydroxylated ether; an amphoteric chemotrope; and testing the treated wellbore fluid for at least one of turbidity and total suspended solids is disclosed. Methods of cleaning wellbores are also disclosed. | 12-09-2010 |
| 20100317549 | EMULSIFIER BLEND - An oil-in-water emulsion that includes a brine continuous phase; and an oleaginous discontinuous phase stabilized by an emulsifier blend, the emulsifier blend comprising: an emulsifier having an HLB greater than 11; and an amphoteric chemotrope is disclosed. Emulsifier blends comprising an emulsifier having an HLB greater than 11 and an amphoteric chemotrope and methods of using emulsifier blends are also disclosed | 12-16-2010 |

| 20100137974 | Stent with Graduated Stiffness - Disclosed herein is a stent having a generally tubular stent body with a first end region, a second end region, and a third region therebetween. The stent has a plurality of circumferential serpentine bands and a plurality of connector columns. Each connector column is located between two immediately adjacent serpentine bands, with each connector column having at least one connector. Connectors are connected at one end to one serpentine band and at the other end to an immediately adjacent serpentine band. The connectors of the first and second end regions have a first length which is substantially parallel to the longitudinal axis, and the connectors of the third region have a length greater than the first length and form an oblique angle relative to the longitudinal axis. | 06-03-2010 |
