Abstract: A method and apparatus for scanning a film, in which the film is illuminated by a light source and the light signal coming from the film is fed in channels to a plurality of imaging devices each defining a channel, wherein an exposure for the channels is adjusted to achieve different exposures of the film in at least two of the channels. The signal recorded by the imaging devices is stored as an image having a high dynamic range.

Abstract: Disclosed are assemblies and articles for restricting leakage of a pressurized fluid from a cavity. In accordance with an embodiment of the invention, a vane support defines at least one land, and an interrupted rim region of a bladed rotor assembly defines at least one segmented ring. The at least one segmented ring protruding outward from the bladed rotor assembly in the interrupted rim region, spans across the cavity and cooperates with the at least one land to define a seal.
