Gregory E Bell is a notable inventor based in Rochester, NY (US). He has made significant contributions to the field of scanning technology, holding a total of 2 patents. His work primarily focuses on enhancing the efficiency and quality of raster input scanners.

Latest Patents

One of Gregory's latest patents is the "Slow Scan Registration Self Alignment System for Raster Input Scanners." This innovative system allows for self-alignment of a raster input scanner in the slow scan direction. At the start of the scan, a target with a variable density image is scanned first until a preset target image line is obtained. The position of the scan carriage is then registered, and from this registered position, the platen is scanned through a predetermined number of scan lines. After this, the carriage is reversed and returns the same number of scan lines, where the target is scanned again. The target image line obtained is compared with the previous target image line to determine if a valid scan cycle has taken place.

Another significant patent is the "Variable Rate Scanning Control." This invention features a scanner with a scanning array on a movable carriage, along with a control for regulating the scanning speed of the carriage. It includes a small buffer between the scanner and a workstation, a buffer capacity sensor for continuously monitoring the residual capacity of the buffer, and a motion sensor that actuates the array to scan an image line each time the carriage moves a distance of one scan line. The controller regulates the scanning speed of the carriage to match the image signal output rate of the array with the image signal input rate of the workstation while maintaining a predetermined level of buffer residual capacity.
