Abstract: A rotor train torsional mode frequency tuning apparatus is provided and includes a rotor train and a coupling element. The rotor train includes first and second shafts and a coupling operably disposed between the first and second shafts and has a torsional mode frequency. The coupling element is disposed at the coupling and is configured to adjust the torsional mode frequency of the rotor train by a change in at least one of inertia and/or torsional stiffness in the rotor train.

Abstract: Systems and devices for thermodynamically regulating portions of a dynamoelectric machine are disclosed. In one embodiment, a fan assembly element includes: an axially inner shroud segment configured to form a portion of an annular assembly about a rotor of a dynamoelectric machine, wherein the axially inner shroud segment includes a rotor hub interface configured to physically connect to a complementary portion of a rotor hub; a set of fan blades physically connected to and extending axially from a face of the axially inner shroud segment; and an axially outer shroud segment physically connected to the set of fan blades.

Abstract: A method of determining a location of an apparatus relative to a previously determined location, the method comprising: detecting a change in motion of the apparatus by use of a sensor or sensors in the apparatus; determining a first estimate of the location of the apparatus at which said change of motion is detected, the first estimate of location being relative to the previously determined location, by use of at least one of said sensor or sensors; holding information relating to a plurality of reference points at which a change in motion is expected; determining that the detected change in motion relates to a first reference point of the plurality of reference points on a basis including the first estimate of the location and at least part of said information relating to the plurality of reference points; and re-setting the first estimate of location to a location of the first reference point.

Abstract: A method and system for performing a handover of a mobile device from a first wireless network to a second wireless network is provided, the mobile device being operably connected, via a tunnel, to a server of a Mobile Internet Protocol (IP) system, and to an information server coupled to the first wireless network and the second wireless network. The method includes transmitting, by the mobile device, a handover data packet to the information server via the tunnel, and transmitting, by the mobile device, the handover data packet to the information server via another route.

Abstract: Disclosed is a method of processing User Equipment (UE) status information in a telecommunication network including a plurality of RANs, first UE and second UE, the method including: sending a first message via the telecommunication network, the first message containing a request originated by the first UE and requesting status information relating to the second UE; and receiving a second message via the telecommunication network, the second message conveying the requested status information, wherein at least one of said first and second messages are processed using a service component which is used for controlling handover of UE between different RANs.

Abstract: A post-cast EDM process is used to remove material from the interior surface of a nozzle vane cavity of a turbine. A thin electrode is passed through the cavity between opposite ends of the nozzle vane and displaced along the interior nozzle wall to remove the material along a predetermined path, thus reducing the thickness of the wall between the cavity and the external surface of the nozzle. In another form, an EDM process employing a profile as an electrode is disposed in the cavity and advanced against the wall to remove material from the wall until the final wall thickness is achieved, with the interior wall surface being complementary to the profile surface.
