Publication number: 20150118063Abstract: An airfoil comprises pressure and suction surfaces extending from a root section to a tip section of the airfoil. The airfoil also comprises a leading edge and trailing edge defining a chord length therebetween. A tip shelf is formed along the tip section between the pressure surface and a tip shelf wall, the tip shelf wall being spaced between the pressure surface and the suction surface. A squealer pocket is formed along the tip section between the tip shelf wall and a squealer tip wall extending from the suction surface. The tip shelf extends from within 10% of the cord length measured from the leading edge to within 10% of the chord length measured from the trailing edge.

Publication number: 20080084381Abstract: A smaller sized flip dot display utilizes a magnetically actuated pixel that rotates between two orientations. The orientations display two different optical states. A simulated dot matrix design improves the aesthetics and consumer appeal, and also permits a flip dot display capable of producing a positive contrast display image with darker colored “ON” pixels contrasting with brighter background and “OFF” pixels by reducing the visibility of the spacing gap between each rotating pixel and the surrounding background. An interwoven configuration of magnetic actuators with a coil around each arm of a U-shaped core may result in lower power consumption, low production cost, and small size required for use in consumer and small mobile devices such as watches and mobile phones.Type: ApplicationFiled: September 27, 2007Publication date: April 10, 2008Inventors: Donald Brewer, David Cope, Andrew Wright, Christopher Corcoran

Publication number: 20070064884Abstract: An approach provides machine and a human user interaction in support of dialog flows. A first state file is generated and specifies a plurality of states of a dialog with the human user. The first state file includes logic for transitioning among the states. A second state file is also generated. The second state file specifies a plurality of states of the dialog and includes logic for transitioning among the states, wherein a common process is utilized to interpret the first state file and the second state file. The common process loads one of the state files and determines an appropriate one of a plurality of resources to populate with data associated with the dialog.Type: ApplicationFiled: August 24, 2005Publication date: March 22, 2007Applicant: MCI, Inc.Inventor: Christopher Corcoran
