摘要:
An airfoil comprises pressure and suction surfaces extending axially from a leading edge to a trailing edge and radially from a root section to a tip section, defining a mean span therebetween. An inner endwall defines an inner endwall contour extending axially and circumferentially from the root section, and an outer endwall defines an outer endwall contour extending axially and circumferentially from the tip section. The inner and outer endwall contours are defined by varying radial deviations from circumferentially uniform nominal inner and outer radii, where one of the radial deviations varies axially and circumferentially by at least three percent of a mean span of the airfoil.

A mixing apparatus includes a hopper, a reel, and at least one auger. The hopper defines first and second chambers. The first chamber is disposed adjacent to the second chamber. The reel is disposed within the first chamber. The reel includes first and second hubs configured to rotate and at least one connecting member connecting the first hub to the second hub. The at least one auger is disposed in the second chamber. The first and second hubs rotate about a common axis of rotation. No connecting member connects a center of the first hub to a center of the second hub along the axis of rotation. An attachment point between each connecting member and the first hub is circumferentially offset with respect to an attachment point between the same connecting member and the second hub.

A method of supporting multiple display configurations in a remote access environment, the remote access environment having a host computing device in communication with a viewer computing device comprises: receiving from a host computing device, by a viewer computing device having one or more viewer displays, a list of rectangles, each rectangle representing the boundaries of one of a plurality of host displays; presenting, by the viewer computing device to an end-user of the viewer computing device, a graphical user interface including means for selecting a configuration for displaying a window representing screen data of the plurality of host displays in the viewable area of the one or more displays of the viewer computing device; and displaying in the selected configuration, by the viewer computing device, the window representing the screen data of the one or more host displays. Corresponding systems are also described.

Compounds effective in inhibiting replication of Hepatitis C virus (“HCV”) or other viruses are disclosed. This invention is also directed to compositions comprising such compounds, co-formulation or co-administration of such compounds with other anti-viral or therapeutic agents, processes and intermediates for the syntheses of such compounds, and methods of using such compounds for the treatment of HCV or other viral infections.
摘要:
Systems and methods for extending the drag-and-drop data transfer mechanism to the remote access environment are described. The extension allows the end-user to select data located on the remote host or the local viewer, drag the selected data to a window on the host or viewer, and drop the selected data in the window. In response, the data is transferred via a network connecting the viewer and the host without any further input from the end-user.
摘要:
A voltage regulator configured to receive a supply voltage from a voltage supply and provide a regulated voltage to digital circuitry is provided. The voltage regulator comprises first circuitry configured to inhibit high frequency energy generated by the digital circuitry from transmitting into the voltage supply, second circuitry configured to inhibit low frequency energy generated by the digital circuitry from transmitting into the voltage supply, and third circuitry configured to maintain the regulated voltage at a substantially constant value in response to a current drawn by the digital circuitry.
摘要:
A protection circuit prevents a surge applied to one end of a signal line from being applied to a circuit connected to another end of the signal line. The protection circuit includes a first diode having an anode coupled to the signal line and a first capacitor having a first electrode coupled to a cathode of the first diode and a second electrode coupled to a first potential. A second capacitor has a first electrode coupled to the signal line and a second diode has a cathode coupled to a second electrode of said second capacitor and an anode coupled to the first potential. A first inductor is coupled between the cathode of the first diode and the cathode of the second diode. A power supply terminal is applied with a power supply potential and is coupled to one end of the first inductor.
