Title: Keith R. Harman and Fence Intrusion Detection

Introduction

Keith R. Harman is an inventor associated with Almonte, California, and Fiber Sensys LLC. His patent work addresses the detection and location of attempts to breach a fence using signals carried along a sensor cable.

Latest Patents

Harman is named on one patent: Intrusion Detectors, and Related Systems and Methods. The invention describes a fence disturbance sensor with signal processors at both ends of a cable. The processors transmit coded pulses and compare responses traveling in opposite directions to identify disturbances and determine their location.

The system analyzes the amplitude and phase of correlated responses in corresponding range bins, helping distinguish relevant disturbances from other signals. It registers an event when a disturbance is detected at the same location and time with a matching audio signature. If a prescribed number of events occur at that location within a set time window, the system declares an alarm. Harman’s record lists 1 patent.

Career Highlights

Harman’s listed patent work is connected with Fiber Sensys LLC and focuses on perimeter security technology. The disclosed approach combines signal processing and cable-based sensing to detect and locate fence disturbances.
