A rotary turbomachine, and particularly a turbojet engine, has a compressor stage that is especially adapted for operation in the transonic region. The compressor stage includes a rotor (1) having a hub (2) and a plurality of compressor blades (3) extending radially therefrom, and a stator having a plurality of compressor blades extending radially between a stator hub and a housing. The hub (2) of the rotor (1), and/or the hub of the stator, and/or the housing of the stator, have a circumferential surface contour that is not continuously rotationally symmetrical. Namely, a concave contour (K) is provided in the circumferential surface of the hub near the base of each blade (3) on the pressure side (PS) thereof, while the circumferential surface on the suction side (SS) of the base of each blade has a contour that is linear, slightly convex, convex/concave, or slightly concave to a lesser degree than the concave contour (K) on the pressure side of each blade. The hub contour slopes and transitions smoothly radially outwardly from the concave contour (K) on the pressure side to the flatter or convex contour on the suction side. In this manner, fluid flow velocities on both the pressure side and the suction side of each blade are reduced, especially under transonic operating conditions, and compression shock losses can be minimized.

Methods and systems allow an application capable of online communication to monitor the availability of different electronic communications sources and provide transition between online and offline operation and between different electronic communications sources. When a change occurs in connectivity source status, such as when the user disconnects from a wireline connection or goes offline or when a connection is otherwise lost due to mechanical failure or loss of wireline or wireless signal or when a reduction in bandwidth or connection speed is detected, the application is automatically transitioned between online and offline status and between different types of connectivity source without user action and without interruption of use of the application. If an online connection may not be obtained via TCP/IP connection, a determination is made as to whether the application and computer operating system are configured for RPC/HTTP connectivity. If the application and computer operating system are configured for RPC/HTTP connectivity, RPC/HTTP connection is attempted.

A system for assigning human resources to service tasks. A long term forecasting module enables one or more users simultaneously working on that module to assign tasks that should be fulfilled in the each specific region, based on analysis of past demand and actual service operations. A mid-term planning module enables one or more users simultaneously working on that module to roughly allocate resources to fulfill actual future tasks and expected task demands. A short-term scheduling module enables one or more users simultaneously working on that module to roughly allocate specific human resources to fulfill actual tasks. A coordination module immediately propagates any change in the parameters of the human resource assignments resulting at any one of the forecasting, planning or scheduling modules to effect the other two modules. An analyzing module repeatedly checks the assignment actual status upon any introduction of an assignment update by the forecasting and planning modules to detect discrepancies and to generate alerts to correct those discrepancies.

This is an improvement of the 1968 Trailing Rotor V/STOL aircraft (Ref. 1). Rotors are mounted on wing-tip pods which can be tilted from the vertical to the horizontal aft position. Rotors are then stopped in the axial-flow condition and indexed to an azimuth position, aft of the wing trailing-edge. Rotor blades are then folded forward (blade-tips upstream of rotor-hubs) and locked into grooves in the tip-pods.

The main improvements over Ref. 1 are: a smaller shift of center-of-gravity during transition to cruise mode, and an easier task of locking blades into the tip-pods.

The main feature of the autorotative aft rotor tilt is that a soft-inplane rotor can be used, which reduces rotor weight. The blade-folding axis is also the blade-flapping axis.

The autorotative mode is used frequently by helicopters during descent. It has been found to be a good, stable mode with rpm-stability. During aft tilt on the UFR, the rotors provide pitching stability to the airframe. During stopping of the rotor, the stability of the autorotating rotor eases the task of passing thru rotor resonance.

Also, the wing can be swept back, which is desirable for 400 kt. cruise speeds and can be used for external stores such as fuel and weapons.

A system and method for providing path planning and generation for automated lane centering and/or lane changing purposes for a vehicle traveling on a roadway, where the method employs roadway measurement values from a vision camera within an effective range of the camera and roadway measurement values from a map database beyond the range of the camera. The method uses the roadway measurement values from the camera to determine a desired path along a first segment of the roadway and identifies an end of the first segment based on how accurately the camera defines the roadway. The method then uses the roadway measurement values from the map database to determine the desired path along a second segment of the roadway that begins at the end of the first segment, where a transition from the first segment to the second segment is smooth.

The present invention provides a contact lens having an orientation feature that does not provide an prism optical distortion and can maintain a predetermined orientation of the lens on an eye. A contact lens of the invention comprises an anterior surface and an opposite posterior surface. The anterior surface includes a vertical meridian, a horizontal meridian, a central optical zone, a blending zone extending outwardly from the central optical zone, a peripheral zone surrounding the blending zone, and an edge zone circumscribing and tangent to the peripheral zone. The presence of the blending zone ensures that the peripheral zone, the blending zone and the central optical zone are tangent to each other. The peripheral zone has a surface that, in combination with the posterior surface, provides in the peripheral zone a lens thickness which is characterized (1) by having a lens thickness which increases progressively from the top of the lens downwardly along each of the vertical meridian and lines parallel to the vertical meridian until reaching a maximum value at a position between the optical zone and the edge zone and then decreases to the edge of the edge zone; or (2) by having a mirror symmetry with respect to a plane cutting through the vertical meridian, by having a substantially constant thickness in a region around the horizonal meridian and by having a thickness which decreases progressively from the horizontal meridian to the top or bottom of the contact lens along each of the vertical meridian and lines parallel to the vertical meridian.

A technique for performing frame erasure concealment (FEC) in a speech decoder. One or more non-erased frames of a speech signal are decoded in a block-independent manner. When an erased frame is detected, a short-term predictive filter and a long-term predictive filter are derived based on previously-decoded portions of the speech signal. A periodic waveform component is generated using the short-term predictive filter and the long-term predictive filter. A random waveform component is generated using the short-term predictive filter. A replacement frame is generated for the erased frame. The replacement frame may be generated based on the periodic waveform component, the random waveform component, or a mixture of both.

The problem of charge leakage in the AC compensation filter for the error amplifier of a pulse width modulation (PWM)-based DC—DC converter is effectively obviated by controllably sampling and storing the voltage across the AC compensation filter, in response to a transition of the operation of a DC power supply from run or active mode to quiescent or sleep mode. The sampled voltage is retained as a compensation voltage throughout the quiescent mode, so that it will be immediately available to the PWM circuitry at the termination of the quiescent interval. This serves to ensure a relatively smooth (low noise) power supply switch-over during a subsequent transition from quiescent to active mode.
