Patent number: 11933708Abstract: A measurement system includes an atomizer, an impactor, a particle counter, and a discharge reservoir. The atomizer has a liquid intake port and a gas intake port configured to aerosolize a liquid received at the liquid intake port. The impactor has an inlet coupled to the atomizer and has a first output port and a second output port. The impactor is configured to separate droplets wherein those droplets smaller than a selected cut point are directed to the first output port and those droplets larger than the selected cut point are directed to the second output port. The particle counter is coupled to the first output port and is configured to count particles larger than at least one particle size cut point. The discharge reservoir is coupled to the second output port.Type: GrantFiled: February 18, 2022Date of Patent: March 19, 2024Assignee: TSI IncorporatedInventors: Hee-Siew Han, Kenneth R Farmer, II, Nathan T. Birkeland, Richard J. Remiarz, Timothy S. Russell, William D. Dick

Patent number: 8711338Abstract: The present disclosure describes a method and apparatus for detecting particles in a gas by saturating the gas with vapor and causing the gas to flow through a chamber with walls that are at a temperature different than the temperature of the entering gas creating a gas turbulence within the chamber resulting in the gas becoming super-saturated with vapor and causing said super-saturated vapor to condense on said particles and form droplets, which are then detected and counted by an optical light-scattering detector.Type: GrantFiled: September 5, 2012Date of Patent: April 29, 2014Assignee: MSP CorporationInventors: Benjamin Y. H. Liu, Thuc M. Dinh, William D. Dick, Aaron M. Collins, Francisco J. Romay

Patent number: 7830510Abstract: The present disclosure has an apparatus for detecting fibers in a gas flowing along a passageway. A laser beam is provided at one end of the passageway and the beam is directed along a length of the passageway through which the gas flows. An electrode system, as disclosed, a quadrupole electrode system is mounted along the passageway to cause fibers carried in the gas to oscillate in a detection zone. A photo detector is positioned laterally of the passageway and detects light scattered by the oscillating fibers and projected through an opening in the passageway to provide an output signal that is a function of the light scattered by the fibers in the detection zone.Type: GrantFiled: February 3, 2009Date of Patent: November 9, 2010Assignee: MSP CorporationInventors: Benjamin Y. H. Liu, William D. Dick, Francisco J. Romay, Mark J. Battista, Pedro Lilienfeld
