Lindsay Lohan's Alcohol-Monitoring Bracelet ??

[billt]

Does anyone know how these thinks work? I know they can put a device on your car you have to blow into to get it to start, but how do these things know if you drank, or are around booze? This is the first I've ever heard of such a thing.  Bill T.

sounds like it would be a hoot at parties!

If it only could tell if she was drinking, I'd guess it monitored perspiration, but if it also can tell if you are in the presence of alcohol, I'd have to guess at an air quality monitor?

Found this:

Every 30 minutes, the bracelet (called a Secure Continuous Remote Alcohol Monitor bracelet, or SCRAM) automatically measures alcohol content in the wearer’s perspiration. The SCRAM bracelet will catch blood alcohol levels as low as 0.02 percent – that’s about one drink or less in an hour. Any attempts to wiggle out of or cut off the bracelet will trigger an alert, too. Once a day, the bracelet will send what it’s recorded to the company’s data center in Colorado.

Hey Bill! Link to story? What's the deal here? I hadn't heard anything about this. (Like I follow THIS train wreck)

I also found this, which states that the measurement is taken above the skin so that air borne alcohol might be measured.  It is considered a flaw in this monitor since cleaning compounds or mouth wash might trigger an alarm.

However, the most pervasive problem with the SCRAM technology is that it is non-specific for beverage alcohol. In published experiments where skin vapor ethanol is measured, a system very similar to that used by SCRAM, the researchers concluded that an effort should be made to exclude extraneous ethanol. Such ethanol can come from a variety of ethanol containing toilet products used by many persons. This non-specificity is due in part to the fact that the measurements are taken above the skin, allowing environmental factors to be inadvertently measured by the device. Perhaps more problematic is that the fact that fuel cells are used to detect the alcohol, and fuel cells are generally non-specific for ethanol, and can potentially respond to other alcohols such as methyl-, isopropyl-, and n-propyl alcohol, and to acetaldehyde. At least in theory, because fuel cells are non-specific, these other types of alcohol, if endogenous, can produce a curve that looks identical to one produced from a verifiable drinking episode.

Keep clicking "next" on the pictures until the one of her comes up.

" Not long after this photo was taken at the MTV Movie Awards, Lindsay Lohan's alcohol-monitoring anklet went off, resulting in another bench warrant being issued. Come on, was an electronic booze-detecting device really necessary?"

Nothing really. There was an article about some kind of fashion flub about something she wore, and it sarcastically made mention that perhaps it was to cover up her "alcohol monitoring bracelet". It just got me thinking because I've never heard of such a thing. But then again I don't get out as much as her.  Bill T.

That is the first thing I thought of. Women often use isopropyl, (i.e. "rubbing alcohol"), to remove makeup, etc. Not to mention there are tons of over the counter cold and cough formulas that contain alcohol. Unless they can "get to her" within minutes of the alarm being triggered to confirm her sobriety, she, or anyone for that matter, could get a bum rap. This seems like a case of technology outpacing common sense.  Bill T.
