Title: Sau-Lon James Hu: Innovator in Underwater Acoustic Technologies

Introduction

Sau-Lon James Hu is a notable inventor based in Providence, RI (US). She has made significant contributions to the field of underwater acoustics, holding 2 patents that showcase her innovative approaches to sound velocity determination and sensor positioning.

Latest Patents

One of her latest patents is titled "Method and system for determining underwater effective sound velocity." This invention outlines a method and system for determining the effective sound velocity between a source of sound energy located at an initial depth Z and an actual target located at another depth. The system utilizes a device such as a computer or microprocessor to implement the method. An effective sound velocity (ESV) matrix is generated, wherein ESV values are a function of actual target depth and elevation angle. This matrix is then used to determine the ESV between the source and the target.

Another significant patent is "Geodetic position estimation for underwater acoustic sensors." This patent describes a system and survey method for estimating the geodetic position of acoustic sensors placed at fixed but unknown locations on the seafloor. The method extends the well-known trilateration survey technique, making ranging measurements from reference points to the point to be surveyed. For acoustic sensors, these measurements are obtained by transmitting an acoustic signal from a near-surface projector and making corresponding timing and position measurements. This requires the calculation of the Effective Sound Velocity, ensuring that bias errors do not propagate to the sensor coordinates.
