Title: Innovations by Larry R McDonald
Introduction
Larry R McDonald is an accomplished inventor based in San Diego, CA. He holds a total of five patents, showcasing his expertise in developing innovative technologies. His work primarily focuses on enhancing security measures in underwater environments.
Latest Patents
One of McDonald's latest patents is the Acoustic Fence, which involves methods and apparatus to determine if an underwater intruder passes under a protective boundary. This sonar sensor system consists of multiple sonar sensor modules strategically spaced along a protective boundary. Each module features a sonar transducer characterized by an omni-directional radiation pattern, allowing for overlapping detection capabilities. The system collects sonar data, including range information of targets over time. A central processor processes this data to estimate the target's path and assess whether it poses a threat based on calculated threat levels.
Another significant patent is the Harbor Fence, designed to detect intrusions into security zones associated with waterfront assets. This system is deployed in water around ships or other assets, serving as a protective line of demarcation. The harbor fence comprises a series of spars that extend above the water surface, connected to an electrical computer with a telemetry subsystem. Each spar is equipped with electronic sensors, such as water immersion sensors and accelerometers, to detect intrusions and communicate their locations to a control station. This system also interfaces with an underwater sonar sensor subsystem to enhance its detection capabilities.
