Title: Innovations by Homayoun Birangi in Oxygen Concentration Technology

Introduction

Homayoun Birangi is an accomplished inventor based in Willoughby, OH (US). He has made significant contributions to the field of oxygen concentration technology, holding 2 patents that enhance the efficiency and functionality of oxygen concentrators.

Latest Patents

Birangi's latest patents include a gas concentration sensor and control for oxygen concentrators. This innovative acoustic oxygen sensor is designed to be used in the output lines leading from the sieve beds. It communicates with a microprocessor to control the production and evacuation cycles of the sieve beds. The sensor determines the duration for which a bed is supplied with compressed air and monitors the pressure of the compressed air. It also calculates the time that the product gas is fed through the flow equalization path to supply purging gas to a used bed. The microprocessor optimizes settings to achieve maximum oxygen concentration and flow rate efficiency by utilizing measured oxygen concentration and flow rate.

Another notable patent is the closed-loop feedback control for oxygen concentrators. This invention features a first molecular sieve bed connected to a four-way valve, which either joins the sieve bed to a pressurized air source or vents it to the atmosphere. A second molecular sieve bed is similarly connected. The microprocessor employs a closed-loop feedback circuit to evaluate the time that the output product gas flows into the used sieve bed. The control system directs incremental advances in the valve setting based on the measured oxygen output, ensuring optimal performance.
