The Newest Generation of Alcohol Sensing
Ankle Bracelet Has Arrived!

Introducing the TattleTale™ Alcohol Sensing House Arrest Ankle Bracelet. With active GPS location monitoring technology that can track and monitor house arrest individuals on a 24/7 basis.

The new TattleTale alcohol sensing house arrest ankle bracelet works with Motorola Bluetooth enabled handsets which transmit the location of the offender, and data from the ankle bracelet sensors. The GPS sensor data is transmitted through the Sprint/Nextel wireless network communication system to an internet user interface.

Private service providers, as well as probation departments, parole officers and court officials can monitor active GPS data for each offender, track the historical data, time and location information, and monitor the current status of each sensor on the ankle bracelet.

The Tattletale has multiple features to provide complete monitoring of offenders. If alcohol is consumed, it is metabolized and diffuses throughout the body. This alcohol is present in various bodily substances such as breath, blood, urine and perspiration. Some percentage of consumed alcohol passes through the skin in the form of ethanol.

The primary sensor measures any changes in the trace ethanol molecules that are emitted from the body and measured against a pre-test baseline trip level for each offender.

Additional sensors in the bracelet measure body mass/proximity (to detect tamper events), measure infra-red light (to detect tamper events), battery voltage levels, and body temperature. The bracelet and handheld GPS tracking device are electronically tethered together so that the bracelet and tracking device cannot be further than 20 feet apart.

The offender cannot simply hand-off the tracking device to another person. Any attempt to remove the bracelet will cause sudden changes to be detected in the proximity sensors and body temperature sensors which will send an alarm notice.

The active GPS technology not only provides location information, it also offers the option to create a “Geo-Fence” whereby a specific location or geographical area may be identified as a restricted area for higher risk offenders.

Sprint/Nextel provides the wireless network so the alcohol house arrest bracelet is not hindered by the drawbacks of land-based/hard-line telephones (some offenders do not have land-line telephone service anymore due to the prolific use of cellular telephones). The equipment also provides instant/direct voice communication with the offender through the active GPS handheld tracking device.

A text message and signal tone will remind the offender that the batteries in the ankle bracelet and GPS tracking device are due to be recharged.

The bracelet is water resistant and shock resistant.

The Tattletale is worn around the ankle and is fitted close to the surface of the skin. The casing is made from a high grade ABS plastic and the straps are made of Santoprene (a high grade plastic/rubber compound). It weighs approximately 4.5 ounces. Power is supplied by an internal rechargeable battery system. The bracelet is light, compact and can be worn without much discomfort.
