If you've got a complex system -- a jet engine, for example -- the last thing you can afford is for it to fail at a crucial time. Frontier Technology says it has a way to predict those failures well before they can happen. Frontier is commercializing a pattern recognition system called NormNet, which it says can analyze any system that uses sensors and predict when a component will fail. The company says its technology has been successfully demonstrated to a number of companies, including Caterpillar, Parker Hannifin and General Electric Aviation. NormNet has also been tested at wind farm companies in Texas and on jet engines for the British Air Force.Frontier's Dayton operations employ 20, including the addition of two to three new jobs over the past two years.
