Abstract:
A method of detecting bioaerosols, including detecting particles and estimating a particle size for each detected particle and determining a fluorescence strength for each detected particle. Comparing particle size and fluorescence strength for each detected particle to arrive at a normalized fluorescence strength per particle and comparing normalized fluorescence strengths over a time period to a maximum threshold, to detect highly fluorescent manmade substances.

Claim (Index 1):
A bioaerosol detector, comprising:\n a. a housing defining a chamber; b. an air stream injection assembly, producing an airstream with entrained particles having an average velocity within a transverse extent, in said chamber; c. a light source, producing a light beam that intersects and crosses said air stream; d. a light detection assembly, configured and positioned to detect light generated by scattering of light from said light beam, by particles in said air stream; e. a digitizer, which produces a sequence of first digital values, representative of light detection, responsive to said light detection assembly; f. a data processor that repeatedly calculates a background noise level, responsive to said sequence of first digital values, and which is responsive to a high density of small particles condition wherein said noise level rises due to small particles in said air stream that are not detected and are sufficiently numerous to raise the noise level, thereby obscuring said particles from detection, by detecting a condition in which said noise level has risen above a threshold.
