Trefoil Corporation, founded in 1994 in Orono Maine, has carried out many software projects over the past 15 years and specializes in databases of all sorts. Trefoil Corporation completed the O*NET Project over a two and a half years period (4 and a half years was projected) under contract to the U.S. Department of Labor. The O*NET Viewer and Database produced by Trefoil replaced the U.S. Department of Labor’s Dictionary of Occupational Titles. Since 2000, the U. S. Department of Labor has continued to build on the products delivered by Trefoil. Around that time Trefoil also delivered some additional workforce development tools to some state departments of labor.
Trefoil has an extensive client base and has produced products for universities, school districts, state agencies, paper companies, forest management companies, print shops, web design firms and startups. We are currently developing software for energy monitoring systems. Trefoil has also created and marketed a product called PC-Pedal®. This device permits users of Windows computers to use a foot pedal to operate keys on a standard PC. This product has been used by equipment manufacturers, the military, stenographers, and has been modified to work as a disability aid.
Trefoil Corporation has won a number of grants to help support its development work. Grants have been won from the National Institutes of Health, the Civilian R&D Foundation and the Maine Institute of Technology. Trefoil Corporation has funneled over $300,000 in grant money to the University of Maine.
