Abstract: A method is provided for detection of an airborne contaminant in a atmospheric environment. The method comprises capturing an air sample from the atmospheric environment; separating candidate particles of interest from particles of non interest in the air sample; generating an image of the candidate particles; identifying a contaminant from among the candidate particles by comparing the image of candidate particles with a plurality of stored reference images, each of which reflects a respective identified contaminant; and notifying a remote third party in response to detecting a contaminant from among the candidate particles.

Abstract: A passive biometric surveillance system capable of controlling access to a secure area or holding area for further interrogation or detainment. The system or apparatus passively measures a subject's various physiological parameters and compares a produced digital figure or facial image to a database. If the image corresponds to a notable individual, the subject is allowed access only to the holding area for further interrogation. If the image does not correspond to a notable individual, the system or apparatus provides an audio and/or video object or stimulus to the subject. The system or apparatus passively measures the subject's post-stimulus physiological parameters and compares these parameters with a predetermined threshold(s). Depending upon the outcome of this comparison, the subject is either allowed to pass into the secure area or is allowed only into the holding area for further interrogation.

Abstract: A method and system removes nuclear, biological and chemical (NBC) agents from an air stream from a facility HVAC. The system includes an irradiation zone, a saturation zone and a precipitation zone. A contaminant detection apparatus controls the irradiation, saturation and precipitation of the air stream. The irradiation destroys biological agents along with saturation of air stream with a water based solution. The biological debris and dissolved chemical agents are precipitated out of the air stream by condenser coils. Nuclear agents are removed from the air stream by a diverting the air stream though a bypass filter containing high mass particulate filters and activated charcoal. The contaminants are stored for later removal and destruction. The contaminate detection apparatus includes NBC sensors.
