Abstract
This invention provides systems and methods of supplying oxygen-enriched air to an enclosed space or compartment. The systems and methods may distill oxygen from ambient air by a molecular sieve pressure cycle mechanism, such as a pressure swing absorption, may generate oxygen from water using electricity or may use oxygen enriched air produced by membrane filtration. The invention helps people improve their wellness, productivity and comfort, improve performance of mental and/or physical tasks, increase their alertness, quality of life and pleasure, reduce their drowsiness, and aid in curing and preventing disease by increasing the percentage of oxygen in the enclosed space to a beneficial and safe level.
Claims65
A system for supplying oxygen-enriched air to an enclosed space, said system comprising:
- means for producing oxygen-enriched air;
- a) a conduit for flowing said oxygen-enriched air into said enclosed space;
- b) an oxygen concentration sensor for measuring the oxygen content of air in said enclosed space;
- and
- c) means for maintaining the oxygen concentration of the air in said enclosed space within a safe range.
A system for supplying oxygen-enriched air to an enclosed space, said system comprising:
- a) a pressure swing adsorption apparatus for producing oxygen-enriched air;
- b) a conduit for flowing said oxygen-enriched air from said apparatus into said enclosed space;
- c) an oxygen concentration sensor for measuring the oxygen content of air in said enclosed space;
- and
- d) means for maintaining the oxygen content of the air in said enclosed space within a safe range.
A system for supplying oxygen enriched air to an enclosed space in a vehicle, said system comprising:
- a) a pressure swing adsorption apparatus for producing oxygen-enriched air;
- b) a conduit for flowing said oxygen-enriched air from said apparatus into said enclosed space;
- c) an oxygen battery;
- d) an oxygen concentration sensor for measuring the oxygen content of air in said enclosed space;
- and
- e) means for maintaining the oxygen content of the air in said enclosed space within a safe range, wherein said safe range is 26-40% oxygen by volume.
