A hyperbaric chamber has been designed to achieve the goals of maximizing safety, minimizing complexity, and minimizing cost of hyperbaric chamber therapy. This design minimizes the volume of compressed gas in the chamber, and eliminates the need for complex gas mixing, carbon dioxide scrubbing,...

The chemically assisted photocatalytic oxidation system (CAPOS) has been proposed for destroying micro-organisms and organic chemicals that may be suspended in the air or present on surfaces of an air-handling system that ventilates an indoor environment. The CAPOS would comprise an upstream and a...
