Publication number: 20220118899Abstract: 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.Type: ApplicationFiled: August 18, 2021Publication date: April 21, 2022Applicant: THE BOEING COMPANYInventors: David R. Space, James A. Fullerton, Timothy J. Arnaud, Jon Burton Shaw, Stephen M. Trent, Ty A. Larsen, Myriam Khalil

Publication number: 20220118288Abstract: 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.Type: ApplicationFiled: September 20, 2021Publication date: April 21, 2022Applicant: THE BOEING COMPANYInventors: David R. Space, James A. Fullerton, Timothy J. Arnaud, Jon Burton Shaw

Patent number: 11175210Abstract: A method for evaluating an air purification system. The method includes generating, with an air flow generator, a flow of air through a test filter so that an upstream air flow exists an upstream side of the test filter and a downstream air flow exists on a downstream side of the test filter. A multiple contaminant mixture is injected, with a fluid injector, into the upstream air flow. Downstream concentrations for each contaminant of the multiple contaminant mixture in the downstream air flow are measured with a contaminant measurement device. Test filter breakthrough curves for each contaminant of the multiple contaminant mixture in the downstream air flow are generated based on the downstream concentrations for each contaminant of the multiple contaminant mixture.Type: GrantFiled: June 24, 2019Date of Patent: November 16, 2021Assignee: The Boeing CompanyInventors: Brian P. Berryessa, David R. Space, Timothy J. Arnaud, Stephen M. Trent

Patent number: 10029797Abstract: 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.Type: GrantFiled: February 26, 2014Date of Patent: July 24, 2018Assignee: The Boeing CompanyInventors: David R. Space, Charles A. Stout, James A. Fullerton, Timothy J. Arnaud

Patent number: 7871038Abstract: Systems and methods for providing airflow in an aerospace vehicle are disclosed. A system in accordance with one embodiment includes an aerospace vehicle having an interior volume with a first portion and a second portion. The system can further include an external air supply device positioned to provide supply air to the interior volume at a variable supply flow rate and a recirculation fan configured to move air positioned within the interior volume between the first portion of the interior volume and the second portion of the interior volume. The system can still further include a controller operably coupled to the recirculation fan and configured to vary a rotation speed of the recirculation fan. Variations in the rotation speed of the recirculation fan can be associated with variations in a recirculation flow rate. In selected embodiments, the system can include sensors and/or data link devices operably coupled to the controller.Type: GrantFiled: May 17, 2007Date of Patent: January 18, 2011Assignee: The Boeing CompanyInventors: David R. Space, Jane V. Matera, Warren A. Atkey, Charles J. Fiterman, John Gray, Timothy J. Arnaud

Publication number: 20100081369Abstract: An apparatus comprises an inlet capable of receiving air around a seat, a contaminant conditioning system, an outlet, and a fan system. The contaminant conditioning system may be capable of removing contaminants from the air to form conditioned air. The outlet may be capable of expelling the conditioned air around the seat. The fan system may be capable of drawing the air from a breathing zone through the inlet, moving the air drawn from the inlet to the contaminant conditioning system to form the conditioned air, and moving the conditioned air out of the outlet.Type: ApplicationFiled: September 30, 2008Publication date: April 1, 2010Inventors: David R. Space, Charles A. Stout, James A. Fullerton, Timothy J. Arnaud
