Abstract: In forming integrated circuits on a wafer, diffuser features are provided adjacent to topographic features so that when a film is formed by spin-coating a liquid precursor over the integrated circuits, the action of the spreading liquid relative to the diffuser features in proximity to topographic features minimizes radial streaks which would have been caused by the topographic features.

Abstract: Interleaved cyclic error correction encoded binary data, of the type employed in the compact audio disk standard for example, in which the parity characters are located in the middle of a codeword, are encoded by a serial encoder to greatly increase the speed at which such data may be recorded. In the invention, the message characters are treated as two polynomials, a left-hand sub-codeword or message block representing the message characters to the left of the parity characters and a right-hand sub-codeword or message block representing the message characters to the right of the parity characters. The encoder of the invention has two parallel inputs (200, 210) which simultaneously receive the message characters of the right-hand and left-hand sub-codewords, respectively, each input receiving one character at a time in serial fashion. The encoder is a serial register in which each stage receives the sum of the contents of the previous stage and (a) the product of the current character of the left-hand sub-codeword multiplied (245) by a respective coefficient of the code generator polynomial and (b) the product of the current character of the left-hand sub-codeword multiplied by a respective coefficient of the residue of an algebraic shift factor, whose degree is equal to the length of the cyclic error correction code minus the length of the sub-codeword, divided by the code generator polynomial.

Abstract: The historical Foucault knife-edge test enables (1) to qualitatively ascertain an optical imaging device's characteristics, for example, whether or not it is a source of optical aberrations. The novel method of the present invention, in sharp contrast, complements the historical Foucault knife-edge test, by expanding the test so as to develop a quantitative interpretation of the imaging device's characteristics.

Abstract: A digital halftone image is produced by providing a binary bit image pattern having a minimum visual noise for each density level in the image, and the binary bit patterns being correlated in a manner that reduces visual noise resulting from transitions between patterns. The patterns are addressed by pixel density and x,y location to produce a halftone image. The patterns are generated by employing a stochastic minimization technique with a constraint to insure correlation between patterns.

Abstract: In any digital imaging system, the digital input signals must be converted to a visible image on some output material or medium. Because the range of this output medium is usually not the same as the input image range, care must be taken in converting the digital input signals into output signals. This conversion is done via the tone-scale transformation function. The type of tone-scale transformation function used largely determines the quality of the output image. A well designed tone-scale transformation function must ensure good contrast, no clipping and the display of the minimum and maximum densities that are present in the input. This invention deals with a reliable and robust technique of generating the tone-scale transformation function for digital projection X-ray input images. The method is based on the histogram entropy of the input image.

Abstract: Characters which touch one another in a document image are identified and separated in accordance with their contours. The objects in the image are divided into two classes comprising, respectively, those having closed inner contours and those which do not. An object in the first class having either a closed inner contour which is not centered in the object or two horizontally offset closed inner contours or more than two closed inner contours is identified as containing two touching characters and is split in accordance with the character stroke thickness observed in the document. An object in the second class whose contours intersect three spaced horizontal reference lines at more than a predetermined number of points is compared against intersection patterns characteristic of single characters. If a match is not found, the object is identified as containing touching characters.

Abstract: A photographic element comprising a photosensitive layer, a flexible cellulose organic ester support film, and a substantially transparent magnetic recording layer having a dried thickness of less than about 1.5 micron exhibits improved magnetic and photographic performance and is particularly valuable as a color or black and white negative or reversal film. A method of preparing the above-described element comprises the steps of continuously extruding a layer of a cellulose organic acid ester solution from a hopper toward a polished casting surface which is moving relative to the hopper; continuously extruding simultaneously a layer of a magnetic dispersion from the same hopper onto the extruded layer of cellulose organic acid ester; depositing the combined layers onto the casting surface with the cellulose organic acid ester layer engaging the polished surface; and stripping the combined support film and magnetic recording layer from the casting surface when the layers are sufficiently set to be self-supporting and to allow such stripping. The method is more efficient and less costly than prior art processes and avoids the need for large quantities of solvents and complex processing steps.
