Title: Innovations by Charles L Patrick
Introduction
Charles L Patrick is an accomplished inventor based in Princeton, NJ (US). He has made significant contributions to the field of sensing technology, particularly in measuring oxygen concentration in breath.
Latest Patents
One of his notable patents is titled "System and method for mainstream exhaled oxygen sensor." This invention discloses a sensing device designed to measure oxygen concentration cycles in breath. The device includes a laser that emits light at an A-band of oxygen, a lens for collimating the light, and a multi-pass cell that contains a replaceable sample cell. The light passes through the multi-pass cell and is attenuated by oxygen present in the sample cell. Additionally, the device features a photodetector that converts the attenuated light into an electrical signal, along with a lock-in amplifier or an equivalent processing circuit to determine the oxygen concentration from the electrical signal. This innovative approach enhances the accuracy and efficiency of oxygen measurement in exhaled breath.
