The newest technology in breath testing is the BAC DataMaste cdm.  This machine is able to print out the slope of the alcohol curve of the breath entering the machine.  In effect, this will demonstrate when a defendant tries to "trick" the machine by manipulating their breath.  It will also limit the defense of the test based on Residual Mouth Alcohol issues.  Don't get excited, however, they have not been purchased or used by any jurisdiction in Ohio...yet!

UPDATE:

I wanted to update this article! We are now beginning to see some jurisdictions using the new CDMs.  We await the decision of the Ohio Dept. of Health which may require all jurisdictions to switch to the new Intoxilyzer 8000.
