Abstract: A circuit utilizing four flip flops and a number of gates is used to prevent character doubling when reading optically with a hand held optical character reader. The character can move partially out of and then back into the scanning view without losing character presence, thereby, preventing character doubling or substitution of characters.
Abstract: A fluorescent resin useful in water based ink jet printing based upon both molecular weight and degree of crosslinking of the resin during the manufacture is made utilizing trimellitic anhydrides, propylene glycol, neopentyl glycol, or both, and zinc acetate.
Abstract: A dual belt drive for use in a document transport using two belts having teeth thereon which mesh to lock a document in place. The belt is spring loaded to compensate for documents of various thickness.
Abstract: An image processing system (10) for displaying a video image of a document includes structure for scanning (12) the document and for generating (24) pixel signals representing gray level data values of the image of the document. Circuitry (80) generates a set of color data values and assigns one of the color data values to pixels having a predetermined gray level data value. Structure (42, 84) displays the pixels having an assigned color data value and generates a color image of the document.
