Title: David M. Shearn: Innovator in Facsimile Technology
Introduction
David M. Shearn is a notable inventor based in Somerset, NJ (US). He holds 2 patents that showcase his contributions to the field of facsimile technology. His work has significantly impacted the way images are transmitted and printed.
Latest Patents
One of David's latest patents is for a laser printing facsimile receiver. This innovative device utilizes a laser beam modulated by a received video signal to scan light-sensitive recording paper, effectively printing an image that corresponds to the video signal. The design includes a feedback loop that ensures the output of the laser beam acousto-optical modulator (AOM) accurately tracks the demodulated received video signal. Additionally, a variable transmissivity filter is automatically positioned to maintain a constant light output intensity, compensating for any decrease in laser beam intensity over time. The optical system also features a lens that adjusts its focus as the paper is scanned, ensuring that the laser beam remains focused throughout the printing process. To enhance image quality, the laser beam output is pulse width modulated, and measures are taken to reduce ripple and patterning in the printed image.
