Title: The Innovative Mind of Gary A. Dir
Introduction
Gary A. Dir, an esteemed inventor from Fairport, NY, has made significant contributions to the field of printing technology. With a remarkable portfolio of 18 patents, his work focuses on enhancing the quality and efficiency of image processing and printing systems. Through his innovative ideas, he addresses complex challenges in the industry, setting new standards in performance and functionality.
Latest Patents
Among Gary's notable inventions are two of his latest patents. The first is a method and apparatus for producing variable width pulses to facilitate printing gray levels without relying on halftone cells. This invention introduces an architecture designed to control printing elements for depositing variable amounts of toner accurately on paper. The architecture integrates a pixel memory that determines the gray level for each pixel in a row, complemented by a counter that increments the gray level. A comparator then evaluates a specific pixel's memory location against the counter's output, guiding the corresponding printing element's response.
The second innovative patent is an electronically variable modulation transfer function (MTF) filter for image sensor arrays. This invention features a liquid crystal birefringent MTF filter that is permanently installed between the lens and the image input scanner array. Its primary function is to reduce image modulation at frequencies susceptible to moire patterns. This technology incorporates a source of electric potential and a control switch that selectively applies the potential, enabling the filter to alternate between filtering states. Additionally, a variation of this design implements a two-stage MTF filter, and a second embodiment combines a tunable liquid crystal scattering MTF filter with a full-width sensor array.
