Additionally, the porous solid matrix provides a rigid structure suitable to withstand vibrations and abuse without compromising device functionality. | 11-05-2015 |
20150321030 | PORTABLE AIR PURIFIER - Provided is a portable air purifier, which includes: a mask part; a first connecting hose having one end connected to the mask part; a second connection hose in which the first connection hose is installed, and at least part of which has an opening for introducing external air; an air purification module that purifies the introduced external air to a predetermined temperature condition and discharges the purified air to the first connecting hose; and a power supply unit configured to supply power to the heater. Since the air purification module for removing poisonous gases or biochemical pollutants through a catalytic reaction of a metal catalyst layer can be semi-permanently used, the conventional inconvenience of carrying an extra canister is removed. | 11-12-2015 |
20150343244 | HYBRID ON-BOARD GENERATION OF OXYGEN FOR AIRCRAFT PASSENGERS - Provided herein is a hybrid system for generating oxygen on-board an aircraft for passengers and/or flight crew to breath. The system includes a first chemical oxygen generator component configured to promptly supply oxygen suitable for breathing upon an emergency situation arising and during an initial descent mode. Heat produced from the exothermic decomposition reactions inherent in several types of chemical oxygen generators can be harvested and feed to a second oxygen generator. The second oxygen generator is a solid electrolyte oxygen separation system that catalytically separates oxygen from air inside specialized ceramic materials at high temperatures, about 650° C. to 750° C., using electrical voltage. The ability to feed heat from the first oxygen generator to the second oxygen generator substantially reduces the lag time until the second ceramic oxygen generator is available to take over as the oxygen supply. | 12-03-2015 |

20160089511 | Device for reducing the carbon dioxide concentration of inhaled air - Anxiety attacks can often be limited or eliminated by reducing the concentration of inhaled carbon dioxide. Disclosed is a handheld device for reducing the carbon dioxide concentration of inhaled air by using stacked sheets having rows of adsorbents deposited thereon and which form a removable cartridge. The cartridge is placed into an adsorbent cartridge cradle to secure the cartridge within the device housing and to maintain ventilation channels through the cartridge. Inhaled air passes through the adsorbent containing cartridge and exhaled air exits the device through a bypass to avoid poisoning the adsorbent with exhaled carbon dioxide. | 03-31-2016 |
20160136376 | METHOD AND APPARATUS FOR GENERATING NITRIC OXIDE FOR MEDICAL USE - A method and system for generating and delivering nitric oxide directly to a patient. A reaction chamber is provided that is located at or in close proximity to the patient and reactants within the reaction chamber react together to produce a predetermined amount of nitric oxide. The reaction is controlled by metering at least one of the reactants into the reaction chamber to generate a predetermined quantity of nitric oxide as required by the patient. The reactants can include a nitrite salt, such as sodium nitrite, and a reductant such as ascorbic acid, maleic acid or a mixture thereof.
