Publication number: 20200179859Abstract: A sensor device is disclosed for providing end of service life indication for an air purification filter. The sensor device has a cylindrical housing for insertion into a sorbent bed of a filter, and can be removed from the bed and reused at the end of the filter service. One or more sensors inside the housing are configured to sense physical/chemical characteristics of air passing through the sorbent bed, and to provide associated data to a sensor conditioning board within the housing. The sensor conditioning board processes the received data and conditions the data as desired. The housing is receivable in a cavity formed in the filter bed. A receiving structure receives the housing therein. Data from the one or more sensors can be used to calculate predicted end of service life of the filter. Other embodiments are described and claimed.Type: ApplicationFiled: February 3, 2020Publication date: June 11, 2020Inventors: Frank DING, Amy E. QUIRING, Michael PARHAM

Publication number: 20170050057Abstract: A respiratory mask has a filter element that is optimally position relative to the inhale and exhale of a wearer's nose and mouth in relation to the size and shape of the filter allowing a direct pathway of the airflow between the wearer's nose and mouth to the filter. A non-permeable section, incorporated in the filter element, filtering structure, the sealing area or a combination thereof, is used to direct and channel the outer dispersed boundaries of the nasal and oral flow to the filter element. The optimally positioned filter coupled with channeling of the boundary flow through the filter element reduces residency time of exhaled breath in the mask.Type: ApplicationFiled: April 28, 2015Publication date: February 23, 2017Inventors: Alyssa Whitney SABOLIS, Chris WARD, Michael PARHAM, Ethan David VOSS, Graham Peter WILSON

Patent number: 8402966Abstract: A filter mask includes an oronasal cup, an inhalation directional cover, and an exhalation diverter body. The oronasal cup encloses a nose and mouth of a user. The oronasal cup is fluidly coupled with a filter. The inhalation directional cover is configured to be joined to the filter. The inhalation directional cover includes an elongated wing portion that is oriented in an inhalation direction that is angled with respect to the center axis of the filter. The exhalation diverter body is fluidly coupled with the oronasal cup. The exhalation diverter body defines an exhalation duct that directs exhaled air out of the oronasal cup along an exhalation direction. The inhalation direction and the exhalation direction are oriented away from a plane of interaction between the user and another person.Type: GrantFiled: September 23, 2009Date of Patent: March 26, 2013Assignee: Scott Technologies, Inc.Inventors: Judge Woodrow Morgan, III, Amy Elizabeth Staubs, Michael Parham, Sioned Owens, Sean Austerbery, Gareth Roberts, Troy Alan Baker

Patent number: 7860662Abstract: A method for determining a service life for a filter includes measuring exposure data and calculating a service life estimate based on the exposure data. The service life estimate is representative of an estimated exposure time that the filter is exposed to ambient conditions represented by the exposure data before the contaminant passes through the filter at a breakthrough concentration. The method also includes obtaining environmental data and establishing a predicted service life based on the environmental data. The predicted service life is representative of a predicted exposure time that the filter is exposed to the ambient conditions represented by the environmental data before the contaminant passes through the filter at the breakthrough concentration. The method further includes determining the service life for the filter based on a comparison of the estimated and predicted service lives.Type: GrantFiled: December 17, 2008Date of Patent: December 28, 2010Assignee: Scott Technologies, Inc.Inventors: Michael Parham, Yuquing Ding
