20150057532 | GUIDEWIRE WITH INTERNAL PRESSURE SENSOR - The present document describes a pressure guidewire comprising a shaft tube, a tip portion and a fiber optic pressure sensor. The shaft tube comprises a middle section and a sensor housing extending distally relative to the middle section, the sensor housing having a distal end. The tip portion extends distally relative to the shaft tube. The pressure sensor is embedded in the sensor housing. The sensor housing defines a cavity, inside the sensor housing, which is distal relative to the pressure sensor and delimited at a proximal end thereof by the pressure sensor. | 02-26-2015 |

20140278014 | SYSTEM AND METHOD FOR ENGINE TRANSIENT POWER RESPONSE - There is provided a system and method for controlling an engine. A request signal indicative of a demand for the engine to output a required power level is first receive. A position control signal is then generated in response to the request signal. The position request signal is indicative of a first request for adjusting a present position of a variable geometry mechanism of the engine towards a commanded position to achieve the required power level. An acceleration rate control signal is further generated on the basis of the position control signal. The acceleration rate control signal is indicative of a second request for adjusting an acceleration rate of the engine in accordance with the commanded position of the variable geometry mechanism. The position control signal and the acceleration rate control signal are then output to the engine. | 09-18-2014 |
20140352314 | GAS TURBINE ENGINE FUEL SYSTEM WITH ECOLOGY VALVE - A gas turbine engine fuel system has an ecology valve for withdrawing residual fuel from primary and secondary fuel manifolds upon engine shut-down. The ecology valve has primary and secondary reservoirs respectively connected in fluid flow communication with the primary and secondary fuel manifolds. The valve further has a reciprocating piston movable from a retracted position when engine start-up is initiated to an extended position which the piston assumes under normal engine running conditions. The movement of the reciprocating piston between the retracted and extended positions controls the flow of fuel from and to the primary and secondary reservoirs. A cross-bleed passage is defined in the reciprocating piston. The cross-bleed passage connects the primary and secondary reservoirs in fluid flow communication only when the piston is in its extended position. In this way, the cross-bleed flow between the primary and secondary fuel manifolds may be initiated only at the end of the engine start-up phase. | 12-04-2014 |

20130319658 | WELLBORE ISOLATION WHILE PLACING VALVES ON PRODUCTION - An internal completion string is anchored within a closed casing valve of a production liner in a wellbore. The internal completion string comprises a packer and a shifting tool. The production liner comprises a casing valve having a port and a moveable member. The annulus defined between the production liner and the internal completion string is sealed, and the shifting tool is remotely operated to move the moveable member away from the port, thereby opening the casing valve. | 12-05-2013 |

20090083252 | WEB-BASED COMPETITIONS USING DYNAMIC PREFERENCE BALLOTS - In one example, a method for ranking items such as contest entries is provided. An exemplary method includes displaying sequential subsets of entries from a plurality of entries for a first user to vote on, e.g., making a selection of their preference of one over the other. The method further includes generating a first preference ballot of displayed entries based on selections by the first user, and ranking the plurality of entries based upon the first preference ballot and at least a second preference ballot received from another user. The ranking may be determined based on the first and second preference ballot by a Condorcet algorithm. Additionally, display of the entries may be determined based on previous selections associated with the contest entries, e.g., based on the state of the contest and/or the history of particular contest entries. | 03-26-2009 |
