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.
Claims20
An apparatus comprising:
- a purified air source;
- a first laminar airflow generator configured to generate a first barrier comprising a first laminar airflow;
- and
- a second laminar airflow generator configured to generate a second barrier comprising a second laminar airflow, the first laminar airflow generator and the second laminar airflow generator configured such that the first laminar airflow and the second laminar airflow converge in front of a seat to form a breathing zone comprising purified air supplied from the first laminar airflow generator and the second laminar airflow generator such that the breathing zone envelopes an inhalation sphere.
A method of providing a purified air to an occupant of a seat, the method comprising:
- receiving the purified air;
- generating:
- a first barrier comprising a first laminar airflow, and a second barrier comprising a second laminar airflow;
- forming and suffusing, by converging the first laminar airflow and the second laminar airflow, a breathing space comprising the purified air;
- and
- enveloping an inhalation sphere of the occupant of the seat with the breathing space.
A method of providing purified air to an inhalation sphere of a passenger in an aircraft seat, the method comprising:
- creating the purified air by purifying an air supply;
- delivering the purified air to a first laminar airflow generator and a second laminar airflow generator, each laminar airflow generator being located in the aircraft seat;
- generating a first laminar airflow from the first laminar airflow generator and a second laminar airflow from the second laminar airflow generator;
- and
- vectoring, using the first laminar airflow generator and the second laminar airflow generator, and combining the first laminar airflow and the second laminar airflow with each other such that the first laminar airflow and the second laminar airflow form and fill, with the purified air, a breathing space that envelopes the inhalation sphere of the passenger, such that the inhalation sphere comprises at least eighty percent purified air.
