Patent number: 10481070Abstract: Sample monitoring and flow control systems and methods are disclosed for monitoring of airborne particulates. A system may include a particle collection filter. The system also includes a fluid moving device for moving a sample through the particle collection filter. Further, the system includes a light source configured to direct irradiating light towards the particle collection filter. The system also includes a light detector positioned to receive the irradiating light passing through the particle collection filter and configured to generate a signal representative of an amount of the received light. Further, the system includes a controller configured to receive the signal and to control the fluid moving device based on the amount of the received light.Type: GrantFiled: April 30, 2019Date of Patent: November 19, 2019Assignee: Research Triangle InstituteInventors: Anthony Clint Clayton, Howard Jerome Walls, David S.

Patent number: 10188973Abstract: A filtration device including a base filtration material having openings for fluid flow there through and a filtration medium. The filtration medium includes a plurality of patterned nanofibers formed on the base filtration material. The filtration medium has a figure of merit greater than 30 kPa?1, where the figure of merit is given by ?Log (Pt)/?P, where Pt is the fractional penetration of a specific aerosol particle diameter and ?P is a pressure drop across the filtration medium corresponding to a face velocity of 5.3 cm/s and particle size of 0.3 microns.Type: GrantFiled: December 6, 2013Date of Patent: January 29, 2019Assignee: Research Triangle InstituteInventors: Anthony Clint Clayton, Howard Jerome Walls, Adam Joseph Rieth, David Samuel Ensor

Patent number: 10099165Abstract: A filtration device including a contoured support having 1) an interior surface, 2) an outside peripheral surface spaced farther from a center of the contoured support than the interior surface, and 3) a rim enclosed and sealed to a perimeter of the contoured support. The filtration device includes macroscopic openings in the contoured support extending from the interior surface to the outside peripheral surface, and a plurality of nanofibers having diameters less than 1 micron. The nanofibers are disposed on the outside peripheral surface of the contoured support, and cover the macroscopic openings to form a filtration medium on the contoured support.Type: GrantFiled: December 21, 2015Date of Patent: October 16, 2018Assignee: Research Triangle InstituteInventors: Howard Jerome Walls, Randall J. Newsome, Anthony Clint Clayton, Robert W. Yaga, David Samuel Ensor

Patent number: 10018551Abstract: A particle detector includes a housing, a light source, and a photo-responsive material. The housing includes a sample inlet and a sample outlet, and encloses a detection cavity. The light source directs irradiating light along a longitudinal axis to particles of a sample fluid flowing in the detection cavity. The photo-responsive material surrounds at least a portion of the detection cavity, and receives measurement light propagating from the particles in a plurality of measurement light paths angled relative to the longitudinal axis. The particle detector may be utilized to measure scattered light and/or light emitted due to autofluorescence. Fluids sampled may include aerosols, bio-aerosols, and liquids.Type: GrantFiled: January 23, 2018Date of Patent: July 10, 2018Assignee: Research Triangle InstituteInventors: Howard Jerome Walls, Anthony Clint Clayton, Randall J.
