Title: Innovations of Anna M Quinn
Introduction
Anna M Quinn is a notable inventor based in Rochester, NY (US). She has made significant contributions to the field of optical systems, particularly in the development of bar code scanning technology. With a total of 11 patents to her name, her work has had a profound impact on the efficiency and accuracy of bar code reading.
Latest Patents
One of her latest patents is an optical system for scanning and reading bar codes. This innovative unitary hand-held bar code scanner and reader produces an elliptical beam, oriented with its major axis along the direction of the bars. The design utilizes optics that employ far field diffraction effects to shape the beam and maintain its elliptical aspect constant over a distance in front of the scanner where bar codes may be located. The optics eliminate parallax, even though the photodetector and light source, preferably a laser diode, are located offset from each other on a board. The housing assembly has channels that mount the board without shock-absorbing devices. A digital microcomputer controller and peripheral devices regulate the optical power output from the laser diode and prevent catastrophic failure if the electrical current exceeds safe limits. Additionally, digital control of the gain of the electronic circuits provides signals for decoding bar code information and operates a motor for oscillating a deflector that scans the beam across the code. The microcomputer also controls interface circuits to ensure compatibility with auxiliary equipment and host computers.
