Latest Patents

One of Derrick's latest patents is focused on motion quality enhancement with white noise. This invention involves a modulator that modifies a scanning beam to project a halftone image onto a photosensitive surface. It includes a sensor that provides signals related to the speed of the photosensitive surface, a converter that generates a signal representing an image quality factor, and a random signal generator that alters the modulation of the beam to counter banding errors in the projected image.

Another significant patent is for a cleaning apparatus designed to reduce blade tuck during removal. This invention features a thin scraper blade that is positioned at a low angle of attack with respect to the photoreceptor. The design minimizes blade tuck occurrence by incorporating a slit that extends laterally from one side of the blade. This innovation improves the range of tolerance for interference between the blade and the photoreceptor surface, thereby enhancing cleaning efficiency.
