Title: The Innovative Contributions of Lev Spevak

Introduction

Lev Spevak, an accomplished inventor based in Highland Park, Illinois, has made significant contributions to the field of acoustic technology. With two patents to his name, Spevak's innovations are paving the way for advancements in fluid leak detection and ultrasonic transducer design, showcasing his expertise and creativity.

Latest Patents

Among Spevak's latest patents is the groundbreaking "Midrange Ultrasonic Transducer." This invention features an acoustic transducer that includes an electrically energized crystal in contact with a flexible plate. The design ensures that the plate oscillates in a flexural mode, with specific circular areas—known as nodes—remaining static while adjacent annular anti-nodes vibrate oppositely. To enhance efficiency, an impedance matching material of uniform thickness is placed between the plate and the surrounding medium. Additionally, concentric plastic layer rings act as barriers to negative anti-nodes, which helps eliminate wave cancellations between the positive and negative anti-nodes.

Spevak also holds a patent for the "Leak Locating Microphone," which is designed for detecting fluid leaks within pipes. This innovative microphone features a housing that allows one end to be inserted into the pipe, facilitating the detection of sound through a diaphragm connected to an acoustic transducer. The system employs several microphones at different locations to cross-correlate sound detection, effectively identifying the precise location of fluid leaks.
