摘要： Disclosed is a method and apparatus for generating a two dimensional (2D) image of a structure (e.g., an organ) that has at least one pixel corresponding to at least one voxel of a three dimensional (3D) image of the structure. First, the surface of the structure in the 3D image is modeled by a geometrical volume such as an ellipsoid. Next, normal maximum intensity projection (MIP) rays are cast (i.e., projected) for voxels of the geometrical volume. The 2D image is then generated using the rays. The 2D image has at least one pixel that corresponds to at least one voxel of the 3D image.

摘要： The monitoring system for a gas turbine engine including a viewing tube assembly having an inner end and an outer end. The inner end is located adjacent to a hot gas flow path within the gas turbine engine and the outer end is located adjacent to an outer casing of the gas turbine engine. An aperture wall is located at the inner end of the viewing tube assembly and an optical element is located within the viewing tube assembly adjacent to the inner end and is spaced from the aperture wall to define a cooling and purge chamber therebetween. An aperture is defined in the aperture wall for passage of light from the hot gas flow path to the optical element. Swirl passages are defined in the viewing tube assembly between the aperture wall and the optical element for passage of cooling air from a location outside the viewing tube assembly into the chamber, wherein swirl passages effect a swirling movement of air in a circumferential direction within the chamber.

摘要： An automatic trash pickup assembly which may be attached to a forward portion of a vehicle such as a trash truck for use in picking up and conveying to a rear portion of the truck, trash, refuse, and the like, which may be packed in any disposable container. An inclined elevating conveyor assembly is attached to the vehicle at one point through a ball and socket assembly and to the front of the vehicle by a sliding bar and sleeve. A fully floating reel is carried above the forward end of the conveyor and is structured to move up or down in response to the size of the trash encountered. A revolving underroller, having extending and retracting cleats, is affixed to the forward end of the conveyor and counterrotates with the floating reel. The conveyor assembly is laterally movable from a position extending directly in front of the vehicle to a position wherein the conveyor swings outboard of the vehicle to remove trash from the sidewalk or curb adjacent the roadway. The attachment of the conveyor assembly to the vehicle allows such sideways movement without subjecting the inclined conveyor assembly to twist or tilt. Further, apparatus is provided for automatically changing the elevation of the forward end of the conveyor in response to changes in height of the surface from which the trash is to be removed.

摘要： An inspection system formed at least from a viewing tube for inspecting aspects of a turbine engine during operation of the turbine engine. An outer housing of the viewing tube may be positioned within a turbine engine using at least one bearing configured to fit into an indentation of a support housing to form a ball and socket joint enabling the viewing tube to move during operation as a result of vibrations and other movements. The viewing tube may also include one or more lenses positioned within the viewing tube for viewing the turbine components. The lenses may be kept free of contamination by maintaining a higher pressure in the viewing tube than a pressure outside of the viewing tube and enabling gases to pass through an aperture in a cap at a viewing end of the viewing tube.
