Thomas A Frank

Title: Thomas A Frank: Innovator in Acoustic Technology

Introduction

Thomas A Frank is a notable inventor based in Middletown, RI (US), recognized for his contributions to acoustic technology. He holds a total of 9 patents, showcasing his innovative spirit and technical expertise in the field.

Latest Patents

Among his latest inventions is the "Air Based Sonar Projector Array." This invention features extendable air-based line arrays of directional projectors affixed parallel to a ship hull. The design includes an anchor and a vibration isolator that separate the arrays from the hull, allowing for optimal performance. Each of the hydraulically-actuated arms connects at a cam to an arm stop affixed to the anchor. A sound vibration dampener is strategically positioned between the arm stops. The arms can extend the directional projectors to an activation position, forming narrow beams into the water that generate sonar waves reflecting from targets. These reflections are then received by a hydrophone on the ship.

Another significant patent is the "Method for Designing an Acoustic Array." This method involves establishing a desired beam pattern, acoustic wavelength, and beamwidth for the array. Geometric parameters are calculated based on these constraints, and the array is modeled as a plurality of elements positioned according to these parameters. An amplitude shading function is calculated, leading to the construction of an acoustic array with an area derived from this function.
