Title: The Innovative Contributions of Irving J Bell
Introduction
Irving J Bell is a notable inventor based in Canoga Park, California. He has made significant contributions to the field of interactive graphic display systems. His innovative work has led to the development of a unique cursor apparatus that enhances graphic data entry.
Latest Patents
Irving J Bell holds a patent for a "Cursor apparatus for interactive graphic display system." This invention allows for graphic data entry through an apparatus that automatically centers a pointing laser beam on a handheld cursor. The system is designed to display and compare full-size overlaid graphical data and projected graphical data on a common display screen. It features a steerable pointing laser that scans the display screen in response to a laser beam deflection circuit. The system also includes laser beam position sensing and indicating circuits that accurately measure the laser beam position.
Career Highlights
Bell's patent includes a sophisticated method for centering the laser beam on the cursor at the display screen. This is accomplished by dithering the beam uniformly about its average position in a discrete dither pattern. The dither pattern is utilized to determine any misalignment of the beam's average position with respect to the center of the cursor. The cursor itself is equipped with photo detector elements that conform to the dither pattern, allowing for precise measurement of graphical features on the display screen.
Collaborations
Some of Irving J Bell's coworkers include Richard H Burns and Michael R Smith, who have likely contributed to his innovative projects and research endeavors.
Conclusion
Irving J Bell's work in developing the cursor apparatus for interactive graphic display systems showcases his inventive spirit and dedication to advancing technology. His contributions have paved the way for improved graphic data entry methods, making a lasting impact in the field.
