Patent

CA 1336211

A breath alcohol testing system for advanta- geous use in unsupervised blood alcohol testing includes a face mask having breath sample receiving means, components of an identity confirming means and components of means for insuring that this identity act and breath delivery are performed by the same person. The system requires that the face mask continuously engage the face of the subject between identity confirmation and breath delivery. By making the continuing physical presence of a subject an operative link in the system during both identity confirmation and breath delivery, the integrity of upsupervised testing is greatly enhanced.
