Abstract: Neural network, particularly one suited for use in optical character recognition (OCR) systems, which through controlling back propagation and adjustment of neural weight and bias values through an output confidence measure, smoothly, rapidly and accurately adapts its response to actual changing input data (characters). Specifically, the results of appropriate actual unknown input characters, which have been recognized with an output confidence measure that lies within a pre-defined range, are used to adaptively re-train the network during pattern recognition. By limiting the maximum value of the output confidence measure at which this re-training will occur, the network re-trains itself only when the input characters have changed by a sufficient margin from initial training data such that this re-training is likely to produce a subsequent noticeable increase in the recognition accuracy provided by the network. Output confidence is measured as a ratio between the highest and next highest values produced by output neurons in the network.

Abstract: Apparatus for casting cellulose acetate film from a hot solution is described. The apparatus includes a casting wheel (12), means (13, 14) for passing heated liquid through the wheel to heat the wheel, means (15) for extruding a band of solution onto the wheel, a take-off roller (16) for taking the band, in the form of a film, off the wheel and further rollers (18, 20, 22) for leading the film (26) to a drier (24) after which, when the solvent has been largely removed from the film, the film is wound up into a roll. The take-off roller (16) and the further rollers (18, 20, 22) are concave whereby a defect in the form of surface imperfections is avoided. The imperfections take the form of short sinuous lines oriented generally parallel to the length of the film.

Abstract: A method for assuring that a multi-layer circuit board (10) has been assembled in a selected order which method incorporates the step of forming a label (201, 204) on each layer of the multi-layer circuit board, with each of the labels having a unique indicia thereon indicative of that layers position in a correctly assembled multi-layer circuit board (10). Additionally, there is provided the step of forming a transparent area (231-234) in each layer above the last layer to be viewed, with the size of each transparent area limited to that necessary to view only the indicia of the following correctly assembled layers, such that an incorrectly ordered layer prevents the viewing of at least one indicia. A replication of the labels, commencing from the last ordered layer to the first ordered layer, provides for a doubling in the number of layers that can be checked for correct assembly order.
