Patent number: 11340153Abstract: A particle detector, having a housing defining a chamber; an air stream injector, producing an airstream in said chamber from air taken from outside said chamber; a light source, producing a light beam that crosses the air stream and wherein said light beam is shaped so that a transverse extent of said light beam has a uniform intensity over said transverse extent of said air stream. Also, a photon detection assembly, including an optical train of lenses, is positioned to accept light from said light beam, emitted by the particles, and to focus this light onto a photon detector. A particle detection assembly detects the particles, responsive to the photon detection assembly. Finally, a particle size estimation assembly estimates size for each detected particle, based on number of photons detected by said photon detection assembly from said particle, as it crosses said light beam.Type: GrantFiled: October 5, 2020Date of Patent: May 24, 2022Assignee: CBRN INTERNATIONAL, LTD.Inventors: Elric Saaski, Dor Yacobi

Patent number: 10794815Abstract: A particle detector that includes a housing defining a chamber, and an air stream injector, producing an airstream with entrained particles, in the chamber. A light source produces a light beam that intersects with and is wider than the air stream. A light detection assembly detects light generated by scattering of the light beam, by particles in the air stream. A digitizer produces a sequence of scattering digital values, each representing light detected per a first unit of time duration. Additionally, a summing assembly produces a sequence of summed scattering digital values, each equaling a sum of a sequential set of n of the digital values, and wherein successive summed digital values are offset by a the first unit of time duration and overlap by n?1 of the first units of time duration with a nearest neighbor. Finally, a detection assembly processes the summed scattering digital values to detect particles.Type: GrantFiled: February 27, 2019Date of Patent: October 6, 2020Assignee: CBRN INTERNATIONAL, LTD.Inventors: Elric Saaski, Dor Yacobi
