Title: Andrew C. Jackson: Respiratory Measurement Inventions

Introduction

Andrew C. Jackson is an inventor associated with Boston University in Brookline, Massachusetts. His work includes inventions for measuring respiratory-system impedance, with particular attention to modeling breathing mechanics and accounting for measurement effects in infants. He holds 3 patents.

Latest Patents

Jackson’s listed patents include “Partial Body Plethysmograph for Measuring Human Respiratory System.” The invention describes a device that encloses part of a subject’s body and applies pressure signals across a selected frequency range. Sensors measure airflow and pressure, while a processor uses those measurements to determine respiratory-system impedance. An eight-element model is used to analyze transfer-impedance data and estimate characteristics of the respiratory system, including at input frequencies up to about 96 Hz.

Another listed invention, “Infant Respiratory Impedance Measuring Apparatus and Methods Using Forced Oscillations,” concerns measuring an infant’s respiratory impedance with forced oscillations. To account for the effects of the mask, the apparatus models a shunt compliance in parallel with components representing the infant’s impedance.

Career Highlights

Jackson’s patent work reflects an emphasis on respiratory measurement and the development of apparatus and methods for analyzing breathing mechanics. The described inventions address both general human respiratory-system modeling and the specific challenges of measuring respiratory impedance in infants.

Collaborations

Jackson’s listed coworkers include Kenneth R. Lutchen and Mark N. Horenstein. His association with Boston University provides an institutional context for this work.

Conclusion

Andrew C. Jackson’s inventions focus on improving respiratory-system impedance measurement through specialized plethysmography, signal analysis, and methods that account for measurement conditions.
