Title: The Innovative Mind of Edward P. Coleman: Advancements in Bar Code Technology

Introduction: Edward P. Coleman, an accomplished inventor based in Fairport, NY, has made significant contributions to the field of bar code technology with a remarkable portfolio of 20 patents. His work exemplifies the spirit of innovation, focusing on improving the functionality and efficiency of bar code scanning systems.

Latest Patents: Among Coleman's noteworthy inventions is a cutting-edge patent titled "Method and apparatus for reducing bandwidth limited noise in bar code." This innovative bar code scanner system utilizes a laser light source that periodically emits a light beam, which is swept across a bar code label. The system features a sophisticated mechanism that turns the laser source on and off following a specific duty cycle.

When the laser is active, a detector generates a first electric signal based on the reflected light from the bar code and the ambient light. Conversely, when the laser is inactive, it produces a second electric signal from the ambient light alone. A unique demodulator circuit plays a crucial role by applying different gains to both electric signals, ensuring that unwanted noise effects caused by ambient light are significantly minimized. This state-of-the-art design incorporates a filter that effectively reduces out-of-band signal components, enhancing the overall performance and reliability of bar code scanning.
