SCRAM Devices

According to a thread running on a local list serve, a Google search shows that the Secure Continuous Remote Alcohol Monitor (SCRAM) is a propriety system of a privately held company, Alcohol Monitoring Systems Inc. That seems intent on marketing their wonderful new product. They cite one "white paper" The Determination of Blood Alcohol Concentration by Transdermal Measurement A White Paper by J. Robert Zettl, BS, MPA, DABFE Commissioned by Alcohol Monitoring Systems, Inc. as verification of their technology and results. But if you actually read the "white paper" there were only three test subject individuals, two women and a man, listed. When N=3, I'm not sure the technology has achieved general acceptance in the scientific community. I could be wrong, but there might be a Daubert issue or two with the SCRAM.

Alcohol Monitoring Systems Inc has this to say about itself. "Established in 1997, Alcohol Monitoring Systems, Inc. manufactures the world's only non-invasive alcohol-detection system that automatically tests for alcohol every hour, 24 hours a day, regardless of the offenders location. SCRAM the Secure Continuous Remote Alcohol Monitor is the first alcohol testing technology to use transdermal analysis to determine an offender's Blood Alcohol Content. SCRAM fully automates the alcohol testing and reporting process, providing community corrections agencies and treatment organizations nationwide with the ability to classify DUI offenders and assess compliance with sentencing requirements, and treatment guidelines. Alcohol Monitoring Systems is a privately held company headquartered in Highlands Ranch, Colorado.
Alcohol Monitoring Systems pioneered continuous alcohol monitoring. Learn all about how we turned technical innovation into a practical alcohol-detection tool to attack the DUI epidemic.

The founders of AMS first began work in the cutting-edge field of Transdermal Alcohol Testing in 1992. This elite group of scientists, engineers, programmers, and alcohol testing experts began working closely with eminent authorities in the fields of biology, forensic toxicology, criminal justice, and rehabilitation, in order to develop SCRAM - the first Secure Continuous Remote Alcohol Monitor. In 1997, they founded Alcohol Monitoring Systems with the clear objective of designing, developing, and delivering the worlds most effective alcohol testing program to the community corrections and alcohol treatment industries.

False positives. Complicated equipment setup. Testing loopholes. Excess staff resources. SCRAM addresses all of these issues, and more. Using the SCRAM System in your program means reducing the demand on staff resources. It means eliminating testing loopholes or a subject''s ability to ignore a request for testing. It means improved detection rates, so that you can quickly and reliably focus your resources on the true violators. SCRAM integrates easily with existing protocols and service providers, and data access is secure and easy——at any time from any location. No costly investments in software, hardware, or IT support.

From 1997 to 2002, AMS was an R&D company dedicated exclusively to the development of SCRAM. The company began BETA testing the SCRAM System in 2002 with independent service providers, as well as with federal, state, and county jurisdictions around the U.S. AMS delivered the first 100 production units of SCRAM in January 2003.

SCRAM employs a breakthrough technique to detect alcohol consumption called Transdermal Analysis. It measures ethanol migrating through the skin to determine a person's Blood Alcohol Concentration (BAC) or in the case of SCRAM, Transdermal Alcohol Concentration (TAC)"


Studies on a wearable, electronic, transdermal alcohol sensor.

The measurement of alcohol consumption over long time periods is important for monitoring treatment outcome and for research applications. Giner, Inc. has developed a wearable device that senses ethanol vapor at the surface of the skin, using an electrochemical cell that produces a continuous current signal proportional to ethanol concentration. A thermistor monitors continuous contact of the sensor with the skin, and a data-acquisition/logic circuit stores days of data recorded at 2- to 5-min intervals. Testing of this novel ethanol sensor/recorder was conducted on nonalcoholic human subjects consuming known quantities of ethanol and on intoxicated alcoholic subjects. The transdermal sensor signal closely follows the pattern of the blood alcohol concentration curve, although with a delay. This paper describes the concept of electrochemical ethanol measurement and presents some of the clinical data collected in support of the sensor/recorder development.
