Alcohol Monitoring Systems, Inc. - Littleton CO

International Classification:

G01N 31/00
A61B 5/00

US Classification:

702 24, 600300, 600301

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.

International Classification:

A61B 5/00

US Classification:

600364

Abstract:

Moisture buildup inside an alcohol monitor that is securely attached to a human subject is due to the inlet air from the subject's skin surface, which constantly emits water vapor in the form of insensible skin perspiration. As the warm moist air flows along the air flow path through decreasing temperatures within the alcohol monitor, moisture will be removed from the air through condensation. The present invention solves this condensation problem by first simplifying the air flow path, eliminating barriers that can trap water. Second, additional changes to the air flow path take advantage of gravity, allowing water to drain out of the alcohol monitor. Third, by better balancing the volume of air sample between the sample collection chamber and the fuel cell sample chamber, the total volume of air taken in is reduced, resulting in an overall reduction in the volume of potential moisture introduced into the alcohol monitor.

International Classification:

A61B 5/00

US Classification:

600364

Abstract:

Moisture may build up inside an alcohol monitor that is securely attached to a human subject due to the inlet air from the subject's skin surface which constantly emits water vapor in the form of insensible skin perspiration. As the warm moist air which has very high humidity flows along the air flow path through decreasing temperatures within the alcohol monitor, moisture will be removed from the air through condensation. The condensation problem is solved by lowering the humidity level in the air sample by mixing the very humid air sample from the body with less humid ambient air, which increases the dew point for condensation. Increasing the dew point in the air sample means that there must be a greater change in temperature along the air flow path of the air sample in order to cause the moisture in the air sample to condense and become water.

Appl. No.:

16/779129

Inventors:

Mark Wojcik - Littleton CO, US
Arthur Jacob Gigler - Littleton CO, US

International Classification:

G08B 21/02
G08B 6/00

Abstract:

Offender location tracking devices have evolved to a point where they are wearable computers. Modern smartwatches are also wearable computers and can be used as offender tracking devices; however, they have the limitation of not being able to detect if they are being tampered with or are removed. A novel security band of the present invention can be used in conjunction with a commercially available smartwatch. The security band of the present invention is able to detect if it is cut or removed and is able to wirelessly notify a smartwatch or optional smartphone. The notification is then relayed to a monitoring center or supervising authority using a cellular telephone network or other wireless communication method.

International Classification:

G01N 33/497
G06K 9/00
G08B 21/18

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.
