Breath alcohol testing system
First Claim
1. A breath alcohol testing system particularly suitable for unsupervised breath alcohol testing of a subject comprising:
- a face mask having an internal surface, an external surface and an edge therebetween, said internal surface further defining a breath tube to convey a breath sample to means for testing said sample, said edge shaped for at least partially enclosing a portion of the face of a subject during delivery of said breath sample into said breath tube;
means responsive to the performance of an identity confirming act performed by said subject to verify the identity of said subject, said performance responsive means at least partially disposed within said face mask; and
means partially disposed in said face mask for insuring that the same subject performs both said confirming act and said delivery of said breath sample wherein said insuring means monitors the location of the face with respect to the mask.

Abstract
A breath alcohol testing system for advantageous use in unsupervised blood alcohol testing includes a face mask having for receiving a breath sample, components to confirm the identity and components to insure 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 unsupervised testing is greatly enhanced.

10. A method for unsupervised testing of an alcohol sample received from a predetermined subject delivering a breath alcohol test sample into a face mask, the method comprising the steps of:
-
comparing a voiced sample delivered within said face mask with prior recorded signals stored in a voice analysis apparatus; confirming the identity of said subject as a necessary condition to the delivery of a breath sample; receiving within a face mask a breath sample to be analyzed by a breath sensing apparatus; monitoring the position of said face mask with respect to said subject to insure that said voiced samples and said breath sample emanate from said subject during continued presence of said subject within said face mask.

11. A breath alcohol testing apparatus particularly suitable for unsupervised breath alcohol testing of a subject comprising:
-
means defining a predetermined location for the delivery by a subject of a breath sample, and for the performance by the same subject of an identity confirming act; a breath sample receiving passageway having a breath receiving port disposed within said location defining means; means disposed within said location defining means for confirming the performance of said identity confirming act; and means for monitoring the continued position of a subject within said predetermined location for confirming that the subject who performs said identity confirming act is the same subject who delivers said breath sample.

12. A breach alcohol testing system particularly suitable for unsupervised blood alcohol testing of a subject comprising:
-
means for receiving a breath sample from a subject in order to determine a blood alcohol level; a face mask partially housing said receiving means, the face mask engaging, enclosing and isolating a portion of the face of the subject during the delivery of the sample; and validity assurance means at least partially housed within said face mask for preventing outside interference during the test and assuring validity of the breath alcohol test wherein the validity assurance means includes means for monitoring the location of the face with respect to the mask. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A breath alcohol testing system particularly suitable for unsupervised blood alcohol testing of a subject comprising:
-
a face mask having an internal surface, an external surface and an edge therebetween, said internal surface further defining a breath tube to convey a breath sample to means for testing said sample, said edge shaped for at least partially enclosing a portion of the face of a subject during delivery of said breath sample into said breath tube; breath alcohol sensing means at least partially disposed within said face mask and in communication with said breath tube, said face mask ensuring delivery of a deep breath sample into said breath tube by substantially isolating said subject during said delivery of said breath sample; and detection means at least partially disposed within said face mask to detect enclosure of a portion of said subject'"'"'s face and to cause said breath test to be failed if said face mask is withdrawn after said detection of facial enclosure but prior to the delivery of said breath sample. - View Dependent Claims (20)

21. A method for unsupervised breath alcohol testing of a subject comprising the steps of:
-
engaging a portion of the face of the subject with a facemask having an internal surface, an external surface and an edge therebetween, the internal surface defining a breath tube to convey the breath sample to means for testing the sample, the edge of the face mask adapted to isolate and enclose said portion of the face; monitoring the location of the face of the subject with respect to the mask during engagement; and delivering into said face mask a breath sample to be analyzed by a breath sensing apparatus while the portion of the face is engaged. - View Dependent Claims (22, 23, 24, 25)

26. A method for unsupervised breath alcohol testing of a breath sample received from a predetermined subject comprising the steps of:
-
providing a face mask having an edge adapted to engage and enclose a portion of the face of the subject; generating a reference voice signal from enrollment words spoken by said subject into said mask with the edge engaging a portion of the face; recording information correlated to said enrollment words; comparing said correlated recorded information with a subsequent voiced sample delivered within said face mask; confirming the identity of said subject via said comparing step as a necessary condition to the delivery of a breath sample; receiving within the face mask a breath sample to be analyzed by a breath sensing apparatus; and monitoring the position of said face mask with respect to said subject during delivery of said subsequent voiced samples and during said receiving step and continuously in time therebetween, thereby to insure that the said voiced samples and said breath sample emanate from said subject when the face of said subject is engaged and enclosed by said face mask. - View Dependent Claims (27)
