The invention relates to a method a method for routing calls and messages in a communication system. In the method a mobile station registers to a call control node using a logical name. The logical name is mapped in a directory to an international mobile subscriber identity. The call control node performs a location update to a home location register using the international mobile subscriber identity. The mobile station is reached using a called party number. As a terminating call or message is received to a core network, a roaming number is allocated for the mobile station, and the call or message is routed to the call control entity currently serving the mobile station. The call control node translates the called party number to the logical name using the directory.

A fluid end 15 for a multiple reciprocating pump assembly 12 comprises at least three plunger bores 61 or 91 each for receiving a reciprocating plunger 35, each plunger bore having a plunger bore axis 65 or 95. Plunger bores being arranged across the fluid head to define a central plunger bore and lateral plunger bores located on either side of the central plunger bore. Fluid end 15 has suction valve bores 59 or 89, each suction valve bore receiving a suction valve 41 and having a suction valve bore axis 63 or 93. Discharge valve bores 57 or 87, each discharge valve bore receiving a discharge valve 43 and having a discharge valve bore axis 63 or 93. The axes of at least one of suction and discharge valve bores is inwardly offset in the fluid end from its respective plunger bore axis.

In an axial turbine wheel including a rotor disk and a plurality of turbine blades each having a base end retained by the rotor disk via a joint and extending radially from the rotor disk, a seal plate is received in outer and annular slots formed in the base ends of the turbine blades and rotor disk, respectively, and an annular shoulder is formed in the wall defining the inner annular slot on a side remote from the rotor disk, the annular shoulder thereby defining an inner narrow section and an outer wide section in the inner annular slot. Thus, the seal plate can be easily placed in position by first fitting the inner peripheral edge thereof in the inner narrow section of the inner annular slot, fitting the outer peripheral edge thereof in the outer annular slot until the inner peripheral edge clears the annular shoulder. Thereby, the outer and inner peripheral edges of the seal plate are received in the outer annular slot and outer wide section of the inner annular slot. The outer peripheral edge of the seal plate may abut the bottom of the outer annular slot so as to allow the seal plate to be firmly retained even when subjected to a large centrifugal force.

A multi-force actuator valve invention including a radially polarized permanent magnet, a pair of associated electromagnetic coils, a movable magnetically operated armature member, a valve located to be actuated by movement of the armature member, and mechanical force exerting means located and positioned to exert a force on the movable magnetically operated armature member. The multi-force actuator valve invention has electrical current control input means for supplying and controlling electrical current to the electromagnetic coils for controlling the movable magnetically operated armature member. The electrical current control input means for supplying and controlling electrical current to the electromagnetic coils for controlling the movable magnetically operated armature member has a plurality of types of controls that allow the multi-force actuator valve invention to operate or function as a plurality of types of valves such as a latching valve or a modulating valve. The electrical current control input means also has switching means for switching between the plurality of types of controls for permitting the multi-force actuator valve invention to be switched from one type of valve to another. In the preferred embodiments the electrical current control input means includes an H-bridge circuit and a modulating circuit.

An aircraft flight control surface has an actuator that employs a magneto-rheological (MR) fluid for dynamically adjusting the responsiveness of the control surface. The MR fluid may be used as a primary or secondary control in the event that a primary control actuator fails. In the event of system failures associated with the primary control, an alternate level of performance may be provided by the secondary control and communicated to the overall flight control system. This permits the control surface actuator to reactively and proactively respond to changes associated with the flight control system. If the design fails, it also permits a safe mode of operation should the ability to dynamically adjust the viscosity of the MR fluid be negatively impacted. The safe mode of operation may involve a reduced level of performance.

The invention relates to a safe, arm and fire integral micromodule designed based on microsystem integrated technology. A core structure of the safe, arm and fire unit is processed to be a SAF integral chip structure by MEMS-CMOS machining process and through design for the safe, arm and fire principal; the integral micromodule can be largely reduced in size while the traditional safe, arm and fire function are simultaneously implemented through design for the electrical connection style of the SAF integral chip, design for primary explosive sequence of the SAF integral chip, priming composition, primary explosives and a flyer; the integral thickness without battery of the micromodule is less than 1cm, size is less than 1 cm<3>; the micromodule can implement a plurality of functions as timed igniting, impact initiation and self-failure etc.

A method of arranging data synchronization of at least one application in a networked system, which comprises at least one terminal, at least one synchronization server, a first database in the terminal, and a second database. In the method, a configuration message is formed which comprises data required for the application data synchronization, said data comprising settings of at least the second database. The configuration message is transmitted from the synchronization server to the terminal. A synchronization connection is arranged between the terminal and the synchronization server to perform the synchronization. The synchronization is initialized using the arranged synchronization connection and at least part of said data, data of the first database and the second database being synchronized using at least part of said data.

A lacrosse head pocket and a related method of manufacture are provided to facilitate consistent, repeatable and/or custom manufacture of lacrosse equipment. The pocket can be constructed from multiple different sections joined with one another, or can be knitted, weaved or otherwise assembled on an automated assembly machine from strands, and/or can be formed as a unitary textile material having regions/sections with different physical and/or mechanical properties. The pocket can be integrally molded within portions of a lacrosse head to eliminate manually constructed connections between the pocket and lacrosse head. The lacrosse head can be integrally molded with a lacrosse handle to provide a one-piece unitary lacrosse stick. Related methods of manufacturing also are provided.

A bottom bracket assembly for bicycle frames aligns crankshaft bearings. The assembly is press fitted into the bottom bracket shell to journal the crankshaft. An elongated, rigid, unibody sleeve comprises a terminal end and a spaced apart leading end which both receive and support a radial contact bearing that is press fitted into a machined bore. Each bore comprises an interference fit zone for bearing retention and a larger, pressure relief zone comprising a channel and an adjacent, buffering slope that compensates for stresses. Dust shields coaxially abut the bearing exteriors. An inner, tubular buttress bushing coaxially occupies the sleeve interior and extends between the spaced apart bearings to brace them. Externally the sleeve has a pair of integral, friction retention contact interfaces separated by a reduced diameter optimization zone. The sleeve terminal end has an integral stop flange that abuts the frame bottom bracket shell contacting the crank arm.
