  • Patent number: 8229142
    Abstract: A device includes a substrate and a transducer attached to the substrate, wherein the substrate includes a surface to which the transducer is attached and at least one edge member extending along at least a portion of the outside edge of the surface. The surface can be a generally planar surface. The edge member is stiffer than the surface. In several embodiments, the transducer is adapted to vibrate. The transducer can, for example, be selected from the group consisting of a piezoelectric transducer, an electrostrictive transducer and a magnetostrictive transducer. Preferably, the transducer is attached to the surface of the substrate by a metallic bonding agent and, more particularly, by welding.

  • Publication number: 20090243282
    Abstract: A fitting arrangement and method of securing a fitting arrangement to a surface is provided. A plurality of adjacent fittings is coupled to and extends from a mounting surface of a structure in a well bore. Each fitting has an engagement surface that is configured to engage with an installation tool for coupling the fitting to the structure. The engagement surfaces of the adjacent fittings in the plurality are offset from each other to thereby define a clearance for the installation tool.

  • Publication number: 20070225097
    Abstract: The electrically variable transmission family of the present invention provides low-content, low-cost electrically variable transmission mechanisms including first, second and third differential gear sets, a battery, two electric machines serving interchangeably as motors or generators and five or six selectable torque-transfer devices. The selectable torque transfer devices are engaged to provide an EVT with a continuously variable range of speeds (including reverse), four or more mechanically fixed forward speed ratios and at least one mechanical reverse speed ratio. The torque transfer devices and the first and second motor/generators are operable to provide six operating modes in the electrically variable transmission, including battery reverse mode, EVT reverse mode, reverse and forward launch modes, continuously variable transmission range mode, fixed forward mode and mechanical reverse mode.

  • Publication number: 20070117668
    Abstract: An electromechanical transmission is provided having an input member for receiving power from an engine and output member. A plurality of gear members is operable for changing speed ratio between the input member and the output member. The input is connected with one of the gear members and the output member is connected with another of the gear members. A motor/generator is continuously operatively connected with the output member (via a planetary gear set) in parallel with the gear member that is continuously connected with the output member. The motor/generator is packaged axially between the input member and the plurality of gear members. The motor/generator is packaged in a packaging space typically utilized for a torque converter in a nonelectro-mechanical transmission. Thus, redesign of the nonelectro-mechanical transmission to achieve the electromechanical transmission involves a minimal number of steps.

  • Patent number: 7218009
    Abstract: A breathing system includes a container to store a gas under pressure, wherein the gas includes air or oxygen. The container includes an outlet through which the gas exits the container. The breathing system further includes a generator system including a generator in operative connection with the container outlet such that energy is supplied to the generator by the pressurized gas. The generator converts the energy supplied by the pressurized gas to electrical energy. The system further includes a fluid path in connection with the generator through which pressurized gas passes after providing energy to the generator and a respiration facepiece in fluid connection with the fluid path.

  • Publication number: 20070055593
    Abstract: A trust accounting system and securities broker platform are closely integrated such that a third-party investment manager is notified of an amount of principal cash that is available for investment. Investments made are reported to the trust accounting system. Information flow between the third-party investment manager and the trust accounting system occurs daily. Consequently, the operator of the trust accounting system, e.g., a bank, can perform its fiduciary oversight duty while maximizing return on investment of principal cash, and beneficiaries can obtain up-to-date information about the state of trust investments and income.

  • Publication number: 20070044977
    Abstract: A packer that is usable with a well includes a resilient seal element and a support member. The resilient seal element is adapted to radially expand in response to the longitudinal compression of the element. The support member is at least partially surrounded by the seal element and is adapted to radially expand with the seal element to support the element. The support sleeve is substantially harder than the seal element.

  • Publication number: 20060243445
    Abstract: Apparatuses and methods allow a downhole anchor device to be cut, released, and retrieved using a single one-trip cutter and removal assembly. The assembly preferably includes a cutter head recessed behind an anchor latch. The latch is landed to the anchor device to be removed and the cutter head is extended therefrom and activated. Once cut by the cutter head, the anchor device is retrieved upon a distal end of the assembly.
