Title: James W. Cullen and Fault-Tolerant Document Image Processing

Introduction

James W. Cullen is an inventor associated with Frederick, Maryland, and Lockheed Martin Corporation. His patent work addresses the reliable processing and storage of document images and coded data.

Latest Patents

Cullen is credited with 1 patent: “Fault Tolerant Method and System for High Availability Document Image.” The invention describes a system that uses separate local area networks for large image files and smaller coded data files. Work group servers operate in primary mode for their own networks and in hot standby mode to provide backup processing. If a server fails, a network manager reroutes image files over the less-utilized coded-data network to a standby server, helping maintain service while accommodating the rerouted traffic.

Career Highlights

Cullen’s patent reflects an approach to system availability that accounts for the different network demands of image files and coded data. The design uses alternate network links and standby processing to support continued document-image operations during a server failure.

Collaborations

Cullen’s listed coworkers include William W. Klein and Robert E. Probst. His work is associated with Lockheed Martin Corporation.

Conclusion

James W. Cullen’s patent presents a fault-tolerant architecture for keeping document-image and coded-data processing available when a work group server fails.
