I think your idea is genius!!! It sounds like a perfect way for parents to ensure their children's safety when they are away at college. Can you e-mail me at angel.maldonado.r@gmail.com, so that we can speak about your product? Thanks
I am not sure if it is up to the judge's descretion or it applies to everyone in Missouri, but it is great for his business. However, the customers are not forced, they can forego driving.
Perhaps attitudes are changing, but my nephew owns a company that installs car audio systems. For the past year the overwhelming bulk of his work has been installing breath interlock systems in the autos of people convicted of driving under the influence. Too many people are sure they are the only people on the road who can handle the amount of alcohol they have consumed.
As an engineer who designed a standards certified breathalyser 10 years ago, you are correct about the selectivity issues of semiconductor sensors. They also have issues around flow rates influencing readings.
We used an inhouse assembled platinum catalyst phosphoric acid micro cell with a solenoid driven silicone bellows to sample the airstream after 1.5 litres of air been expelled. The ethanol would be 'reacted' fuel cell like to produce a peak in around 5 seconds. Even then stated accuracy was +-10%.
This is the method most law enforcement units use. Evidential units will normally use infrared with pre and post sampling of a reference gas.
That is an astonishing statistic, Chuck. I had no idea it was that high. Makes you wonder how high the percentage is for texting and talking on cell phones. In some cases, cell phone records are used to see if the driver was on the phone when a fatal accident occurred:
You're absolutely right, cvandwater, it actually is very simpl to avoid driving drunk. Yet, somehow, 32% of our annual highway fatalities in the U.S. are caused by drivers over the limit. Seems incredible, but it's true.
Thanks for the link, Al. that was good thinking to avoid adding a Blood Alcohol Content reading to the app. Very responsible. That could certainly be used to justify what might actually be drunken driving.
For 3D printing to make the jump from rapid prototyping to manufacturing, engineers will need to find easier ways to move products from their CAD screens to their printers.
Gigabit and PoE are two networking technologies moving ahead in tandem as industrial users power remote Ethernet devices such as IP security cameras at 1,000 Mbps over existing CAT5 cable.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
