System and method for locating and determining substance use
View Patent ↗In devices that determine levels of substance use, a substance level in a test sample provided to the testing device by a test subject is determined. A sequence of images are captured to include a portion of the face of the test subject providing the test sample and a display of the testing device. A value indicative of the substance level detected within the test sample is determined. A validity indicator indicating validity of the value indicative of the substance level is determined. A current location is determined. The value indicative of the substance level, the validity indicator, and the current location are sent to a remote server.
1. A mouthpiece for coupling with a testing device of the type that measures a substance level contained in a breath sample provided by a test subject through the mouthpiece, the mouthpiece comprising:
a flange having a substantially oval outer shape and forming a substantially round inner passage through the flange with a first inner surface; and
a plurality of first protrusions formed on the first inner surface such that the first inner surface is irregularly shaped and not smooth;
the plurality of first protrusions preventing a tube from sealing with the first inner surfaces.
2. The mouthpiece of claim 1 , wherein the plurality of first protrusions prevent pressure of a sample provided through the tube from reaching sufficient pressure to trigger the testing device.
3. The mouthpiece of claim 1 , further comprising:
an oval shaped lip ring positioned on, and smaller than, the flange, the lip ring having an outer surface for sealing with lips of the test subject and a second inner surface; and
a plurality of second protrusions formed on the second inner surface such that the second inner surface is irregularly shaped and not smooth;
wherein the plurality of second protrusions prevent a tube from sealing with the second inner surfaces.
4. The mouthpiece of claim 3 , the plurality of second protrusions prevent pressure of a sample provided through the tube from reaching sufficient pressure to trigger the testing device.
5. A mouthpiece for preventing cheating during user of a testing device of the type that measures a substance level contained in a breath sample provided by a test subject through the mouthpiece, the mouthpiece comprising:
a lip ring with a substantially oval outer shape onto which the test subject places their lips when blowing into the testing device;
a flange adjoining the lip ring and having a substantially oval outer shape larger than the lip ring and forming a substantially round inner passage through the flange with a first inner surface; and
a plurality of first protrusions formed on the first inner surface such that the first inner surface is irregularly shaped and not smooth;
the plurality of first protrusions preventing a tube from sealing with the first inner surface.
