The immediate response of a biological threat detection system (BTDS) requires that that several key elements associated with such an attack be monitored simultaneously. The mere detection of bacterial spores, for example, bears little significance without the contemporaneous occurrence of a range of other phenomena. The W-L system is comprised of a distributed array of detector stations, each capable of classifying aerosol particulates in its neighborhood and
interacting with the other detector stations spanning the areas to be protected.
Key to the detection of a bio-threat is the ability to track its progress, predict to what regions it is moving, and establish safe evacuation routes for the affected population to follow. The W-L systems are designed with such a requirement in mind. In addition, pinpointing of the source and location of the release must be determined as rapidly as possible to correlate with the usual on site monitoring cameras to aid in the capture of the individual(s) responsible for the attack.
Finally, each DS must be capable of detecting and retaining exemplars of the bio-threat agents as they pass through. These may be analyzed later (or simultaneously by on-board smart chips, if so configured) for epidemiological and therapeutic responses.
Because the Wyatt-Lorenz distributed system identifies a bioterrorist intrusion using several independent classifiers, the system is expected to have an extremely low false positive alarm rate. Each Detector Station (DS) provides its own analysis which is then compared and correlated to those generated by the other DS units in the net.
Combining the analysis of only two such DS will result in an average false positive rate within the range of 10-7 to 10-9.
Since particles identified as probable agents (i. e. with a probability greater than 90%) are collected immediately by each classifying DS, subsequent “smart chip” or similar laboratory processing of several of these collected particles will further reduce the false positive rate to well below 10-15 providing, thereby, an unequalled screening accuracy. Equally important is the expected false negative alarm rate expected to be well below 10-8.
In addition to the Immediate Warning System, W-L will manufacture and sell tools derived from these systems to be used for remediation and forensic purposes following bioweapon attacks or industrial accidents involving bioagents. Once the fact that an attack has occurred is verified, a portable, handheld detection unit can be used to locate the exact site of the attack. The unit can be programmed to recognize particles of interest and issue an alarm immediately upon detecting such particles. The location
believed to harbor the particle can be queried by loosening particles either ultrasonically or with an air burst, and the device can then be used to analyze the particles and issue an alarm if they match the pre-programmed profile. Clean-up of the area can be monitored in a similar fashion, as well. In addition, this apparatus will collect the particles of interest and store them for future examination and/or destruction.
