Abstract

A system and method of monitoring sobriety using a handheld breath testing device that, on receipt of a user's breath, generates a breath test signal comprising substance content data and user identification data, and wirelessly transmits the breath test signal to a breath test signal receiving station, and wherein the breath testing device further includes a fingerprint reader and a plurality of sensors.

Claims (34)

1. A handheld device for monitoring the sobriety of a user, the handheld device comprising:

a mouth piece for receiving a user's mouth;

a conductive area positioned on said mouthpiece;

a user identification device positioned on a case of the handheld device; and

a conductive area positioned on said user identification device, wherein the handheld device is configured to obtain a resistance measurement at the conductive area positioned on said mouthpiece and a resistance measurement at the conductive area positioned on said user identification device.

2. The handheld device of claim 1 , wherein the handheld device is further configured to measure a difference between the resistance measurement at the conductive area positioned on said mouthpiece and the resistance measurement at the conductive area positioned on said user identification device, and determine whether the difference falls within a specified range.

3. The handheld device of claim 1 , further comprising a wireless transceiver.

4. The handheld device of claim 3 , further configured to transmit one or more substance content signals.

5. The handheld device of claim 4 , wherein the one or more substance content signals include a user identification.

6. The handheld device of claim 5 , wherein the user identification is a fingerprint.

7. A handheld device for monitoring the sobriety of a user, the handheld device comprising:

a mouth piece for receiving a user's mouth and the user's breath;

a conductive area positioned on said mouthpiece from which a first resistance is measured during operation;

a user identification device positioned on a case of the handheld device for receiving the user's fingerprint;

a conductive area positioned on said user identification device from which a second resistance is measured during operation; and

a wireless transceiver.

8. The handheld device of claim 7 , wherein the handheld device is further configured to measure a difference between the first resistance and the second resistance and determine whether the difference falls within a specified range.

9. The handheld device of claim 7 , further configured to transmit one or more substance content signals.

10. The handheld device of claim 9 , wherein the handheld device is further configured to measure a difference between the first resistance and the second resistance and to transmit the one or more substance content signals if the difference falls within a specified range.

11. The handheld device of claim 9 , wherein the one or more substance content signals include a user identification.

12. The handheld device of claim 11 , wherein the user identification is a fingerprint.

13. A handheld device for monitoring the sobriety of a user, the handheld device comprising:

a camera for taking a digital image of the user;

a mouth piece for receiving a user's mouth and the user's breath;

a conductive area positioned on said mouthpiece for obtaining a first resistance measurement;

a user identification device positioned on a case of the handheld device for receiving the user's fingerprint;

a conductive area positioned on said user identification device for obtaining a second resistance measurement; and

a wireless transceiver.

14. The handheld device of claim 13 , wherein the handheld device is further configured to calculate a difference between the first resistance measurement and the second resistance measurement and determine whether the difference falls within a specified range.

15. The handheld device of claim 13 , further configured to transmit one or more substance content signals.

16. The handheld device of claim 15 , wherein the one or more substance content signals include one or more user identifications.

17. The handheld device of claim 16 , wherein the one or more user identifications include a fingerprint.

18. The handheld device of claim 16 , wherein the one or more user identifications include a digital image.

19. The handheld device of claim 16 , wherein the one or more user identifications include one or more of a fingerprint and a digital image.
