Title: Laurie T. Fialkowski and Passive Acoustic Depth Determination

Introduction

Laurie T. Fialkowski is an inventor associated with La Plata, Maryland. Her patent work addresses passive acoustic methods for determining depth in shallow water.

Latest Patents

Fialkowski is credited with 1 patent, titled “Method of Passive Acoustic Depth Determination in Shallow Water.” The invention uses at least one standard acoustic sensor positioned below an ocean thermocline. The sensor records acoustic data from a moving broadband noise source in two frequency regimes: one above a cutoff frequency and one below it.

The method generates a plot of acoustic intensity by frequency over time, then uses curve detection to produce waveguide-invariant density distributions for both frequency regimes. These distributions are used to classify whether the noise source is located below the thermocline.

Career Highlights

Fialkowski’s documented patent contribution focuses on applying acoustic measurements and signal analysis to shallow-water depth determination. The approach compares information from frequency regimes on either side of a cutoff frequency to support classification.

Altan Turgut is identified as a coworker associated with Fialkowski. The provided information does not specify further details about their collaboration.

Conclusion

Laurie T. Fialkowski’s patent describes a passive acoustic technique that uses sensor data and waveguide-invariant analysis to assess a noise source’s position relative to an ocean thermocline.
