Title: Garland R. Granzow and Distributed Shipboard Damage-Control Technology.

Introduction

Garland R. Granzow is an inventor associated with Leesburg, Virginia. His work includes a patented system designed to improve how ships collect, share, and act on engineering casualty and damage-control information.

Latest Patents

Granzow is credited with 1 patent, titled “Distributed Intelligence Engineering Casualty and Damage Control.” The invention uses a local area network carried over a vessel’s AC power lines to connect sensors, equipment, and control nodes throughout the ship.

The network’s nodes can operate as Terminal Units or Data & Control Units. Terminal Units provide a touchscreen interface and maintain a local database of archived and current casualty-control information, updating it with data received from local sources and other network nodes. They can also monitor conditions, control equipment, and exchange information and commands. Data & Control Units perform monitoring and control tasks without a touchscreen or operator interface.

The system’s power line carrier transceivers use direct digital modulation with ROM-stored waveforms for transmission. On reception, a passive linear-phase bandpass detection filter and a switchable phase-locked/Costas loop support rapid, reliable acquisition of phase-shift-keyed signals.

Career Highlights

Granzow’s patent describes a distributed approach to shipboard engineering casualty and damage control. By using existing AC power lines for communication, the system connects strategically placed nodes and supports coordinated monitoring, equipment control, and information sharing across a vessel.

Collaborations

The supplied information associates Granzow with Electronic Innovators, Inc. and identifies John P. Massey as a coworker. It does not specify their respective roles in developing the patented system.

Conclusion

Garland R. Granzow’s patented system combines power-line networking, distributed data management, and equipment control to support shipboard casualty and damage-control operations.
