Abstract: A trim element having a body and a covering element extending over part of the body. The covering element includes at least two substantially rigid panels connected to one another by a flexible branch forming a bending line of the panels relative to one another and fastened to the body by a fastening edge forming a hinge between the panels and the body, the covering element being deformable around the bending line. The covering element hinges between a retracted position, in which the panels of the covering element are pressed against the body, and a deployed position, in which the panels are moved away from the body, the covering element defining a storage volume with the body in the deployed position.

Abstract: The present invention discloses groundwater heat transfer system comprising a primary pump suspended in a well and connected to at least one water supply pipe, a heat exchange system being connected to said primary pump via a secondary pump, a return pipe being connected to the heat exchange system and returning water from the heat exchange system to the well, wherein the primary pump provides motive pressure to a primary nozzle of a liquid jet ejector submerged in the well, which entrains filtered groundwater through a secondary nozzle of the liquid jet ejector, wherein the secondary pump, placed after the primary pump and before the heat exchange system, provides the remaining system head.

Abstract: Apparatus and methods for assessing contamination of formation fluid. A downhole sampling tool is operated to draw fluid from a subterranean formation into a chamber of the downhole sampling tool. The downhole sampling tool is then operated to discharge the fluid from the chamber while monitoring pressure of the fluid and volume of the chamber. Contamination of the discharged fluid is assessed based on the monitored fluid pressure and the monitored chamber volume.

Abstract: A downhole tool for conveyance within a wellbore extending into a subterranean formation. The downhole tool comprises a moveable member comprising a first surface defining a moveable boundary of a first chamber, and a second surface defining a moveable boundary of a second chamber. The downhole tool further comprises hydraulic circuitry selectively operable to establish reciprocating motion of the moveable member by exposing the first chamber to an alternating one of a first pressure and a second pressure that is substantially less than the first pressure.

Abstract: The techniques herein relate to a probe for forming a seal between a downhole tool and a wall of a wellbore. The probe includes a probe inlet extending from the downhole tool for fluid communication with a subterranean formation, a base positionable about the downhole tool about the probe inlet, a packer positionable on the base for forming a seal with the wellbore wall, and a raised packer support and/or packer stopper for supporting the packer as the packer is compressed against the wellbore wall. The packer may have an inlet channel extending therethrough for receiving the probe inlet. The raised packer support can extend from the base for supporting the packer, and the packer may have a support channel extending a distance therein for receiving the raised packer support. The packer stopper can extend from the base about a perimeter of the packer with an expansion gap defined therebetween.

Abstract: Techniques for determining at least one downhole parameter of a wellsite are provided. A sensor apparatus is operatively connectable to a downhole tool deployable into a borehole of the wellsite, the downhole tool having a conduit system for receiving downhole fluid. The sensor apparatus has a housing, at least one gauge, a gauge carrying body positionable in the housing for receiving the gauge, and a flowline extending through the gauge carrying body for operatively connecting the conduit system to the gauge whereby parameters of the downhole fluid are measured. The gauge has at least one pressure sensor and at least one temperature sensor. The gauge carrying body has a pressure resistant block and a thermal absorber positionable about the gauge.

Abstract: The present disclosure relates to a media recognition game. In an illustrative embodiment, the game is provided on a smartphone application. The application can be provided on a graphical user interface. The smartphone can be connected to, but is not required, a network interface for communicating with an online service such as the Zune Marketplace®, Rhapsody® or iTunes®. In operation, the application can retrieve media from the online service or local data storage. In turn, a portion of the media can be played to the user. The user can then provide, to the best of their ability, an identifier for the media. The application can determine whether the user was correct and display a message dependent on whether the user's identification was right.

Abstract: A duplexer for microwave signals that requires no system of settings by screws. The duplexer includes two tunnels, each having a longitudinal passage and compartments demarcated by transversal partition walls. The compartments, the longitudinal passages and the common part are hollowed out in the plane upper surface of a monolithic block. The tunnels are closed on the top by a lid that adheres uniformly to the plane surface.

Abstract: A pyrotechnic firing device for tools connected to a firing plunger movably mounted in a launch tube. The device consists of an inner barrel or frame (1), and a firing gas generator (9) housed in a modular breech (7) at one end of the launch tube (5) secured to a weight (3) which receives the recoil on the breech (7) during firing and is connected to one end of a damping cylinder (6) between the frame (1) and the weight (3). The device is useful as an easily adaptable and convertible firing device capable of being fitted with a wide variety of tools.
