Title: The Innovative Contributions of Robert A. Lapetina
Introduction
Robert A. Lapetina is a notable inventor based in Salt Lake City, UT (US). He has made significant contributions to the field of underwater acoustics, holding a total of 5 patents. His work primarily focuses on piezoelectric transducer assemblies, which are essential for sonar applications.
Latest Patents
Lapetina's latest patents include a two-dimensional piezoelectric transducer assembly and a line array transducer assembly. The two-dimensional piezoelectric transducer assembly is designed for producing sonar signals for underwater transmission and detecting reflected sonar signals. This assembly features a planar array of piezoelectric elements housed in an elastomer casing, which are coupled to electronic circuitry for signal processing. The elements are closely packed and selected for low cross-coupling characteristics, with some oriented perpendicularly to the array plane.
The line array transducer assembly is a flexible design for detecting underwater acoustical signals. It consists of an array of spaced-apart piezoelectric elements arranged in a line, chosen for their low sensitivity to incoherent mechanical perturbations and high sensitivity to coherent mechanical perturbations. The elements are polarized transversely to the array, with electrodes on opposing surface areas that carry signals produced when stressed by acoustical signals. This assembly is encased in a porous, open-cell material and enclosed in a water-tight jacket, ensuring durability and functionality in underwater environments.
