Abstract: A portable handheld wireless breath alcohol monitoring device (RBAM) utilizes facial recognition from an enrollment image or gallery of images accumulated over time, and automatic retesting if an initial test is positive for alcohol or of an initial facial match is negative. A location fix is captured with each breath test taken by an offender. After each breath test, the breath alcohol content (BrAC), date and time of the breath test, facial image data, and location fix are uploaded through a built-in cellular phone module in the RBAM to a monitoring station. The monitoring station evaluates each breath test and determines if immediate notification to a supervising agency is needed. If so, an email, text message, or page is sent to the supervising agency. RBAM enables the monitoring of lower-risk offenders or offenders who have earned the privilege of a less intrusive alcohol testing and monitoring program.

Abstract: An improvement in monitoring alcohol levels through transdermal testing is provided by detecting if environmental gasses, referred to as interferents, have been introduced into a transdermal vapor sample. An insensible skin perspiration sample may not be completely controlled and can contain interferents from an environmental source rather than the subject. Before testing a skin perspiration sample, the alcohol sensor is sampled and averaged to establish a baseline value. A sample is drawn and presented to the alcohol sensor. The output of the alcohol sensor is monitored to determine the amount of alcohol in the sample. A maximum alcohol sensor value for the transdermal alcohol monitor is set by determining the baseline value when no alcohol is present in the sample. Subsequent baseline values during a reading above the maximum alcohol sensor value indicate that an environmental interferent is present in the alcohol sensor.
