Using optical technology, engineers created a way to measure the amount of alcohol in a driver’s skin. They use near-infrared absorption spectroscopy to measure blood alcohol content. The light enters the arm and a detector collects reflected light. It uses a helium-neon laser as the internal reference source, and is a non-invasive alternative to current methods.
The system measures the light reflected back, which reveals how much alcohol is in the person's skin. So all they do is simply lift the lid which exposes the touch pad and this is how the light comes out of the machine and will go in and out of his tissue.
Law enforcement officials are enthusiastic about a new tool for alcohol testing that uses near-infrared absorption spectroscopy to determine a person’s blood-alcohol content more swiftly, and in a more sanitary and less invasive way, than current methods. The TruTouch 1100 system can also function as a biometric identity-verification system for prison work-release programs or airline pilots. These new techniques are really innovative and will definitely put a new label on testing people for alcohol.

I thought the article was very interesting, how it spoke of a new technology that I haven't heard of. That's great how they're trying to discover new ways to measure the amount of alcohol in a person's blood. I would like to know more about it and if they plan on testing it out and what the results are. Overall, nicely done!
This article was very good. Joe explained this new alcohol tester technology in a very concise manner. Another thing that I thought was well presented was the way he mentioned that this new replacement of the breathalyzer is a very swift, and efficient testing device that will be very useful to law enforcement officers. The article thoroughly explains how IR Spec can be use to measure how much alcohol is present in a persons skin. Lastly, I liked the way the article was written, and organized. I would be curious to see how accurate this new device is, and also how expensive it is and when we might be seeing it used by local police. Overall, this was a great article.
Article was interesting. i liked learning about new alcohol technology. Joe did a good job in writing the article.
This was a well written write up and brought up a topic that we have covered in class. I like how they are finding new ways to find BAC of people even with the technology they already have. I think that you could have put an example and how it is or will be used to make new measurements. I think you should have done a little bit of comparison between the old BAC tests and this one. I learned from this article that there are more ways than just the breathalyzer test to find blood alcohol content.
I thought this article was very well written and it kept my attention throughout the whole passage. Joe explained in detail about the new alcohol tester technology. This article was also able to explain how IR Spec can be used to measure the alcohol level in ones skin. This was a great overall, it would be interesting to hear about what trials have been taken on this device and its percent accuracy.
This article was very well written and was a very interesting topic. It was something that I didnt know before and was something that most people are probably not familiar with and thats is why i think this was a good article to choose. Good job!
I thought that Joe did a nice job with this review. In particular, I felt that the review was well done in that it exposed a new scientific advancement that may be applied in the forensic world by using spectroscopy to measure blood alcohol contents of individuals expected to be intoxicated behind the wheels. In addition, i thought that Joe did a good job in analyzing the article and pinpointing its key points, as he also managed to explain the science behind the new method in simpler terms. Two things that may have made the review better would have been an in depth reference of the other methods previously used and insight as to when exactly the new method is planned to be put into affect. Overall, the review met my expectations and educated me about a new method that may be used to determine blood alcohol content.
