Identifying drunk drivers will get a lot quicker and easier using this new infrared alcohol test--developed by TruTouch Technologies, an Albuquerque, N.M. start-up. Using the fact that body tissue with alcohol in it absorbs more light than normal tissue, the device detects alcohol levels by shining infrared light on the subject's skin and analyzing tissue based on how it reflects that light. The test takes 60 sec. to produce results vs. 20 min. for a Breathalyzer test and hours or days for a standard blood test. http://trutouchtechnologies.com/ ; ; http://www.aip.org/dbis/stories/2007/17122.html http://www.time.com/time/2006/techguide/bestinventions/inventions/medicine.html
