BI TAD™ includes Continuous Alcohol Monitoring and Electronic Monitoring in One System

October 23, 2009
Boulder, CO

In a breakthrough for community corrections, BI Incorporated, a national provider of technology, treatment and training services for community-based offenders, announces the availability of BI TAD™, a device that continuously monitors for alcohol consumption through a noninvasive skin sensor worn on an offender’s ankle. BI TAD, or Transdermal Alcohol Detector, also includes radio-frequency monitoring capabilities, meaning individuals on the system can be monitored for curfews and alcohol use with the same device.

TAD’s highly accurate and reliable alcohol monitoring system is a valuable tool for states and counties whose court systems and correctional facilities are clogged with DUI and DWI offenders. TAD is a water-resistant, battery-operated device worn around the ankle 24 hours a day. The TAD sensor rests against the offender’s skin. If an offender drinks alcohol while wearing a TAD ankle bracelet, the sensor detects a “drinking event” via sensible perspiration (sweat) and insensible perspiration (vapor) emitted through the skin. The bracelet transmits data to a receiver installed in the offender’s home. This data is transmitted to a host computer which then disseminates and distributes the information to supervising authorities as needed.

“Agencies have struggled to enforce court or agency-ordered sobriety when a person is released to community supervision. With BI TAD, offenders know they are being monitored for alcohol use all the time, which will lead to changed behavior and increased public safety,” said Bruce Thacher, BI President and CEO. “In addition, by including home detention capabilities to TAD, supervising agencies will know if the person deviates from court-ordered schedules and curfews.”

BI partnered with respected engineering and research firm Giner, Inc., of Newton, Mass., for the sensor technology within the TAD unit. Formed in 1973, Giner has been at the forefront of electrochemistry research and transdermal sensing technology that offers rapid sampling since the 1990s. BI has provided alcohol monitoring technologies for community corrections professionals since 1992.

TAD home detention capabilities

The BI TAD radio-frequency capabilities are similar to those in BI HomeGuard® 200. Using radio-frequency technology, TAD can monitor the absence or presence of an individual at home, ensuring compliance to court- or agency curfews and schedules. “This clearly places TAD ahead of its competitors in capability and versatility,” said Victor Rompa, director of product development, BI Incorporated.

TAD’s ability to monitor alcohol consumption and curfew compliance with one system is a cost-saving opportunity for agencies that refer offenders with alcohol problems to community supervision. TAD’s other features include:

  • Simple enrollment platform via BI TotalAccess® software
  • Round-the-clock secure officer login available at
  • Receiver that operates via landline or cellular connection
  • Alerts in multiple forms (fax, email, PDA) are sent to supervising officers
  • Variable range settings for curfew monitoring
  • Field-replaceable battery
  • Lightweight device weighs eight ounces
  • Many tamper-resistant features to ensure system reliability
  • Expert technical support from monitoring center and product specialists
