METHOD AND APPARATUS FOR DETECTING ILLICIT SUBSTANCES |
摘要 |
The present invention includes a method and apparatus for detecting use of illicit substances, according to scheme represented in Figure 5. A sample of breath is analyzed using electronic sensors, including surface acoustic-wave gas sensors (20). The method determines the presence and concentration of the substances (or a class of substances). Diagnostic software is used to identify substances where a stored library of signatures is compared to the signature obtained from the system. Signal processing and neural networks are preferably utilized in the analysis. |
