Abstract: A headrest ventilation assembly is configured to secure to a headrest of a seat assembly, and includes an air conduit including one or more air inlets and one or more air outlets, and an air filter disposed within the air conduit between the one or more air inlets and the one or more air outlets. The air filter is configured to remove contaminants from the air that is drawn into the air conduit before being delivered out of the one or more air outlets. The assembly can also include a fan disposed on or within the air conduit. The fan is configured to draw the air into the one or more air inlets and provide airflow to deliver the air out of the one or more air outlets. The assembly can also include one or more ultraviolet (UV) light emitters disposed on or within the air conduit. The UV light emitter(s) are configured to emit UV light into the air to sanitize the air before the air is delivered out of the one or more air outlets.

Abstract: An environmental control system is provided. The system includes a sorbent regeneration device. The sorbent regeneration device includes at least one regenerative sorbent material operative to remove gas substances from air. The at least one regenerative sorbent material is operatively coupled to a source of hot air. The sorbent regeneration device further includes at least two bypass valves that are operative to selectively direct some or all of the hot air into the at least one regenerative sorbent material. The environmental control system further includes one or more air quality sensors and a controller operatively connected to the at least two bypass valves and the one or more air quality sensors. The controller is operative to control one or more of the at least two bypass valves in response to air quality determined from the air quality sensors.

Abstract: A personal ventilation device and method include a first duct segment and a second duct segment both held by a support structure that is configured to be mounted on a wearer of the personal ventilation device. The personal ventilation device also includes a first nozzle mounted to the first duct segment and a second nozzle mounted to the second duct segment. The first and second nozzles are configured to be disposed proximate to opposite sides of a face of the wearer and the first nozzle directs airflow from the first duct segment across the face of the wearer to form a control volume for a breathing space of the wearer.

Abstract: A method for providing purified air to an occupant of a seat in a mask lacking corporeal features that is generated by an apparatus. The apparatus includes a contaminant conditioning system that delivers purified air to a first and a second laminar flow generator. Each laminar flow generator produces a respective laminar flow that combines to form and fill a breathing space with purified air that envelopes an inhalation sphere of the occupant and inhibits air other than the purified air from entering the breathing space.

Abstract: A ventilation assembly comprises a number of fan systems configured to purify air and a number of air distribution assemblies. Each air distribution assembly of the number of air distribution assemblies is configured to be removably installed on a seatback of a passenger seat. Each air distribution assembly of the number of air distribution assemblies comprises a pair of air distribution vents, ductwork configured to receive air from at least one fan system of the number of fan systems and direct air to the pair of air distribution vents, and a seat attachment device configured to removably couple the pair of air distribution vents to the seatback such that each air distribution vent is situated on opposite sides of the seatback for providing purified air to a seated passenger.

Abstract: A compact, lightweight, low power aircraft air filtration and VOC removal unit enables the removal of VOCs from cabin air in a passenger aircraft. A plurality of baffles having air flow-through airflow spaces are spaced apart along a duct. UV LEDs are mounted on the interior sides of the outermost baffles, and on both sides of all interior baffles. A filter module is disposed between pairs of baffles, and spaced from the baffles sufficiently to illuminate the entirety of both sides. Each filter modules comprises a plurality of filters. The filters are selected from a coarse foam, a fine foam, or a fused quartz filament felt. Each filter is loaded with a catalyst including one or more of AEROXIDE® P25, other pure titanium dioxide (TiO2), iron-doped TiO2, carbon-doped TiO2, and combinations thereof. The catalysts on the filters, under UV illumination, chemically reduce VOCs in the airflow to non-VOC molecules.

Abstract: An Environmental Control Systems (ECS) for an aerospace vehicle comprises an air supply airflow path inputting, monitoring, and conditioning air from external to the vehicle, and a recirculation airflow path inputting, monitoring, filtering, and moving air from one portion of the interior of the vehicle to another portion. The air supply airflow can include a dynamically controlled VOC/ozone converter, which can be operated when the aerospace vehicle is on the ground. The recirculation airflow path can include a dynamically controlled regenerative gas contaminant filter and/or VOC/CO2 removal device. The filter/adsorption media of the controlled regenerative gas contaminant filter and/or VOC/CO2 removal device can be regenerated by suppling hot air or a vacuum, and gaseous contaminants can be broken down for removal from the regenerative gas contaminant filter by controlling UV irradiation. The controller can alert a flight crew if air quality falls outside predetermined or programmable parameters.
