Abstract: According to the present invention, a cooling circuit is provided disposed between a first wall portion and a second wall portion of a wall for use in a gas turbine engine, one or more inlet apertures, and one or more exit apertures. The inlet aperture(s) provides a cooling airflow path into the cooling circuit and the exit aperture(s) provides a cooling airflow path out of the cooling circuit. The cooling circuit includes a plurality of first pedestals extending between the first wall portion and the second wall portion. The first pedestals are arranged in one or more rows.

Abstract: A system and method is disclosed for manipulating images. The system includes a digital computer, input and output peripherals, and a program which provides a plurality of functions for manipulating various images. The images are processed to generate unique objects which may be modified by an operator. The program also allows integration and data transfer to various systems including video games, other digital computers, etc. The system may be used to transfer data to the video game in order to replace characters with the actual image of the player. The system may also be used to perform animation of an image, simulate facial movement resulting from speech, and simulate cosmetic reconstruction of a body portion in real time. The program is further capable of generating three-dimensional representations of an image being manipulated.

Abstract: An apparatus and method for cooling a wall for use in a gas turbine engine is provided that includes a cooling air passage having a plurality of segments connected in series by one or more chambers, an inlet aperture, and an exit aperture. The inlet aperture connects the cooling air passage to one side of the wall. The exit aperture connects the cooling air passage to the opposite side of the wall. Cooling air on the inlet aperture side of the wall enters the cooling air passage through the inlet aperture and exits through the exit aperture.

Abstract: This invention relates to a seal for protecting an end of an idler roll against contaminants. The seal includes a fastener engageable with the end of the idler roll and an integral first sealing member molded onto the fastener and extending radially outward from the fastener. A second sealing member is integrated with the first sealing member. The first sealing member and the second sealing member project into frictional engagement with the end of the idler roll. When assembled with the end of the idler roll, the first sealing member and the sealing member are biased into frictional engagement with the end of the idler roll, thus protecting the end of the idler roll from contaminants in wet environments.

Abstract: A method and apparatus for cooling a wall within a gas turbine engine is provided which comprises the steps of: (1) providing a wall having an internal surface and an external surface; (2) providing a cooling microcircuit within the wall that has a passage for cooling air that extends between the internal surface and the external surface; and (3) increasing heat transfer from the wall to a fluid flow within the passage by increasing the average heat transfer coefficient per unit flow within the microcircuit. According to one aspect, the present invention method and apparatus can be tuned to substantially match the thermal profile of the wall at hand.

Abstract: A system and method for producing a digitized likeness of a person. The system includes a digital computer and a scanning device operatively coupled to the digital computer. Headshot photographs of a person are scanned and the data is transmitted to the digital computer. A program is provided for manipulating the data and reconstructing a digital image for display on the digital computer. The program allows customization of the expressions on the face of the digital image. The program also allows enlargement and reduction of the digitized likeness while maintaining necessary proportional relations. The program also allows integration and data transfer to a Computer Aided Manufacturing (CAM) system so that three dimensional contours and depressions corresponding to facial features may be automatically reproduced.

Abstract: A bypass air valve for a gas turbine engine is provided which includes a liner, a strap, and means for selectively actuating the valve. The liner includes an inner radial surface, an outer radial surface, a plurality of first regions, and a plurality of second regions. Each first region includes a plurality of first apertures. Each second region includes a plurality of second apertures. The strap includes a plurality of openings and a plurality of third regions. Each third region includes a plurality of third apertures. The valve may be selectively actuated into an open or a closed position. In the open position, the first regions are substantially aligned with the openings and the third regions are substantially aligned with the second regions. In the closed position, the first regions are substantially aligned with the third regions and the second regions are substantially aligned with the openings.
