Title: John Lehr: Innovator in Acoustic Imaging

Introduction

John Lehr is an accomplished inventor based in Newton, MA, known for his contributions to the field of acoustic imaging. With a total of two patents to his name, Lehr has made significant strides in developing technologies that enhance our understanding of respiratory tract morphology.

Latest Patents

One of Lehr's latest patents focuses on an innovative apparatus designed for acoustic imaging. This single hand supportable and operable device provides an output signal that characterizes the morphology of the respiratory tract. The apparatus includes an acoustic pipe that exchanges acoustical energy with the tract. The pipe features an open first end that communicates with an opening in the respiratory tract. A transducer, such as a loudspeaker, is coupled to the pipe to launch acoustical energy, producing an incident wave towards the opening and a reflected wave that forms a transient wave field in the pipe. This transient wave field is representative of the morphology of the tract. Additionally, pressure wave sensing transducers, such as microphones, are mounted along the length of the pipe to provide transduced signals that are processed to yield an output signal indicative of the tract's morphology.
