  • In 1981, Jeffrey Feit, a student in New Jersey, was placed in a statewide innovation contest with a primitive schematic of a breathalyzer-based interlock device. In 1983, Hans Doran, a student in Limerick, presented a working prototype at the Young Scientist competition in Dublin. 
  • Alcohol-sensing devices became the standard through the 1980s. They employed semiconductor (nonspecific) alcohol sensors. Semiconductor-type (Taguchi) interlocks were sturdy and got the field moving, but did not hold calibration very well, were sensitive to altitude variation, and reacted positively to non-alcohol sources.
