  • Patent number: 8701033
    Abstract: A method supplies or creates a generic electronic index for a hardcopy printed item. The generic electronic index is based on the text within the hardcopy printed item. From this generic electronic index, the method creates a plurality of custom electronic indices from the generic electronic index. Such custom electronic indices can be based on user input and/or user feedback or can be created by marketing agencies, educational institutions, etc. Each of the custom electronic indices is a variant of the generic electronic index, and each of the custom electronic indices is adapted to a different target audience.

  • Patent number: 7576763
    Abstract: Reflex writing is a group of algorithms developed to maintain color registration in xerographic systems using multiple imagers, in which sequential color separations are written based on events in the spatial domain. The imaging system includes a raster output scanner imager for the black station and a light emitting diode bar for the color station. A simulated machine clock signal is generated based on a running average of a plurality of actual machine clock periods determined from pulses received from a photoreceptor module drive roll encoder. For each black scanline written the distance the belt travels is tracked using the simulated machine clock signal, and when the black latent image scanline has traveled the known distance between the two imagers, the light emitting diode scanline is written registered with respect to the raster output scanner scanline.
