A method and apparatus for inspecting a photolithography mask for defects is provided. The inspection method comprises providing a defect area image to an image simulator wherein the defect area image is an image of a portion of a photolithography mask, and providing a set of lithography parameters as a second input to the image simulator. The defect area image may be provided by an inspection tool which scans the photolithography mask for defects using a high resolution microscope and captures images of areas of the mask around identified potential defects. The image simulator generates a first simulated image in response to the defect area image and the set of lithography parameters. The first simulated image is a simulation of an image which would be printed on a wafer if the wafer were to be exposed to an illumination source directed through the portion of the mask. The method may also include providing a second simulated image which is a simulation of the wafer print of the portion of the design mask which corresponds to the portion represented by the defect area image. The method also provides for the comparison of the first and second simulated images in order to determine the printability of any identified potential defects on the photolithography mask. A method of determining the process window effect of any identified potential defects is also provided for.

Signature analysis of streamed download data narrows a list of likely candidates after a search engine search has been performed. “Streamed download” means that the data is brought byte by byte to the searcher's computer and then discarded. During the streaming process the subject data, in binary form, is parsed into segments and each segment is provided with a signature based on the content of the segment. The signatures of the individual segments are then compared to signatures of the material that may have been infringed. If there are no matches, the streamed download data is discarded. If there are enough matches of the signatures, the offending data is displayed for visual inspection. Only caching and display takes place if a potential infringing segment is discovered.

An optical inspection system uses an illumination gradient to gradually spatially vary the intensity and/or specular characteristics of the illumination reflected from the surface of a specular object to determine surface gradients of the object. The surface gradients can be used to reconstruct a three-dimensional image of the object. The illumination gradient can be produced by an illumination apparatus that includes circular arrays of light-emitting elements. The illumination gradient can also be produced using an optical element that gradually alters the illumination intensity of the reflected illumination in accordance with the incidence characteristics of the reflected illumination on the optical element. The illumination gradient enables the use of numerous illumination angles to reduce error in estimated surface gradients without increasing imaging or processing time.

An air seed meter for an agricultural planter includes a vacuum cover which has a central opening which exposes the central portion of the seed disc to the exterior. The central opening of the vacuum cover is centered on a location offset from the axis of rotation of the seed disc. This reduces disc wear at the disc-vacuum cover interface, and renders the disc more accessible for self-cleaning, visual inspection and verification of the proper disc. Openings in the central, open portion of the disc, the back wall of the seed housing and the side wall of the seed housing cooperate to equalize the air pressure in the seed reservoir to atmospheric pressure and reduce or eliminate reverse air currents in the discharge chute. An adjustable brush with three separate stations cooperates with an edge-release, beveled disc to apply a progressively more forceful singulation force to eliminate duplicate seeds.
