Abstract: A turbocharger comprises a turbine wheel (5) mounted within a housing assembly (1, 3) for rotation about a turbine axis, a gas flow inlet passage (8) upstream of the turbine wheel (5), and a gas flow control mechanism (10, 16, 32) located within the housing assembly (1, 3) upstream of the turbine wheel (5) and operable to control gas flow through said gas flow inlet passage (9). An actuator assembly is mounted to the housing assembly and comprises: A lead screw including a lead screw shaft (37) defining a lead screw axis, and a lead screw nut (36) threadedly engaged on a threaded portion of the lead screw shaft (37). The lead screw (36, 37) being arranged so that rotation of one of said shaft and nut relative to the housing assembly produces linear movement in the other of said shaft and nut in the direction of the lead screw axis: The lead screw (36, 37) engages the gas flow control mechanism (10, 16, 32) at a location within a housing cavity defined within said housing assembly (1, 3).

Abstract: A contact number encapsulation system is disclosed that is operable to consolidate a plurality of contact numbers associated with a given user into a single contact number. The system includes a call processing application that uses information contained in a SIP message header to determine a list of contact numbers to call. The SIP message header contains a call destination indication that is used by the call processing application to retrieve the list of contact numbers. The list of contact numbers is user defined and may be updated or modified by an account holder at any given time. Once the list of contact numbers is obtained, a simultaneous call module is used to simultaneously call each number contained in the list. As such, the account holder only needs to provide the primary contact number to individuals desiring to reach him/her instead of various numbers that are associated with various locations the account holder may be located.

Abstract: The present invention relates to optoelectronic and/or electrochemical devices comprising an organic charge transporting material which is liquid at a temperature of ?180° C. In particular in dye-sensitised solar cells, quantum efficiency higher than with prior art solid organic hole-transporters is reported. The melting point of a large quantity of organic charge transporting materials may be adjusted to a desired value by selecting suitable substituents. Accordingly, general advantages of the liquid state may be associated with the properties of organic charge transporting materials.

The method further includes controlling an actuator based on the adjusted target EGR mass flow.

Abstract: A method of, and apparatus for, arthroplasty of a knee joint comprising obtaining a desired spacing of the femur from the tibia by inserting a spacer into the knee joint between the femur and the tibia. The spacer is used as a reference for securing a guide jig in position about the knee joint for guiding resection of one or both of the femur and tibia for fitting of tibial and/or femoral prostheses. A method of resecting the femur while moving the tibia through an arc of motion to remove bone to the desired depth, a method of determining the position of the guide jig, the guide jog, an alignment device and the spacer are also described.

An external power interface is included to connect to an external electrical power source. An AC electric power distribution bus is included to power electric loads of the vehicle and a power switch device is provided to selectively provide AC electric power on the power distribution bus from one of the respective power sources with a default to select one of the sources whenever it is present.

Abstract: One embodiment is a fuel system for an internal combustion engine including a fuel pump having a fuel pump gear operable to drive the fuel pump to pressurize fuel. The fuel pump gear is offset relative to engine top dead center by a predetermined angle to reduce a sound or noise. The offset can be determined by selecting the minimum sound produced over a range of offsets or operating conditions.

Abstract: One embodiment of the present invention is an internal combustion engine system that includes an internal combustion engine, a turbocharger with a compressor and a turbine and a gas flow pathway defined therebetween, one or more pressure sensors to detect pressure along the gas flow pathway, an emission control device structured to receive exhaust from the turbocharger, and a controller responsive to input from the one or more pressure sensors. The controller determines a control signal indicative of turbine outlet temperature as a function of such input, and selectively generates an output signal to adjust temperature of the exhaust provided to the emission control device from the turbocharger in response to the control signal.

Abstract: A method of initiating a pour of a liquid alloy comprises the steps of filling an interior of a crucible with a displacement plunger and the liquid alloy until a metal head of the liquid alloy exceeds a critical height. The crucible has a bottom pour opening with a plug inserted therein. The plug is configured to be buoyant within the liquid alloy when the liquid alloy is below the critical height. Pour is initiated by at least partially withdrawing the displacement plunger until the metal head drops below the critical height.

Abstract: One embodiment of the present application is a gas turbine engine with a compressor that includes a variable geometry mechanism to vary working fluid flow area. A desired state of this mechanism is selected different than a current state to change the amount of flow area. The mechanism has a hysteresis band corresponding to a difference between increasing the flow area to reach the desired state and decreasing the flow area to reach the desired state. To control operation of the mechanism within this hysteresis band, a determination is made whether the desired state corresponds to a greater flow area or a lesser flow area relative to the current state.

Abstract: Removable circuits and related mounting hardware for removably connecting circuits to a vehicle's control system. Circuits and connectors form an addressable assembly which may be enclosed in a flowable material.

Abstract: A hydraulic seal is defined between a rotating member such as a turbocharger shaft and a stationary member such as part of a bearing housing of a turbocharger. The members define a projecting annular disc that is received in an annular channel that is filled with hydraulic sealing fluid such as oil. Rotation of the rotary member applies a centrifugal force to the fluid thereby ensuring that it is retained in the channel between walls thereof and the disc. This annulus of fluid provides a hydraulic seal around the shaft between the bearing housing and the compressor or turbine housing. The oil is delivered into the channel from a supply in the rotary member. One of the walls of the channel serves as a weir whereby when the channel has an excess supply of oil is overflows the wall and passes the drain.

Abstract: An electrostatic drive includes a first electrode and a second electrode responsive to a drive signal. The drive signal includes an actuation signal constituent and a sensing signal constituent. The sensing signal constituent is at a frequency higher than a natural mechanical resonant frequency of the electrostatic drive. In response to the actuation signal constituent, displacement between the first electrode and the second electrode changes, which is evaluated by detecting a change in an electrical characteristic of the drive as a function of the sensing signal constituent.
