Title: Innovations of Robert F. Allis
Introduction
Robert F. Allis is a notable inventor based in Rochester, NY (US). He has made significant contributions to the field of imaging technology, holding a total of 7 patents. His work primarily focuses on advancements in image input terminals and scanning technologies.
Latest Patents
One of his latest patents is for a Multiple Mode Raster Scanner. This invention features an image input terminal (IIT) equipped with an automatic document handler that feeds documents into a registered position on the IIT platen. The IIT includes a pair of multi-element scanning arrays, which work in conjunction with a scan lamp and optics on a movable carriage. This setup is designed to optimize the scanning process. The analog image signals generated by the scanning arrays are processed in separate channels before being combined into a serial stream. This stream can be thresholded or screened to produce binary level image signals or converted to multi-bit gray scale. A microprocessor-based control system synchronizes the operation of the scanning carriage, document handler, and image signal processing, ensuring efficient data management and quality control.
Another significant patent by Allis is the Alignment System for Scanning Arrays. Similar to the previous invention, this IIT also features an automatic document handler and multi-element scanning arrays. The processing of analog image signals follows the same methodology, allowing for high-quality image output. The control system in this invention also includes features for automatic signal gain control and the deletion of bad image signals or pixels. Additionally, an onboard array alignment apparatus allows for adjustments in focus, skew, height, position, and overlap of the scanning arrays.
