Timeline of Innovation TRI Historical Timeline of Innovation 1977 Developed Compressed Air/Gas Testing Patented a compressed air testing kit for collecting air samples from tanks used by divers,firefighters, and hazardous materials workers. This system was originally designed for theU.S. Diver’s compressed air quality sampling and TRI Air Testing continues to hold theU.S. Navy and Coast Guard air sampling contract. TRI pioneered the science ofcompressed air and gas testing and services a wide range of industries including fire,service, dive, medical, manufacturing, pharmaceutical , food/beverage, industrialand the Government and Military. 1984 Sonar Transducer Reliability Program (STRIP) TRI and University of Washington were the only nongovernmental participants in theprogram. STRIP combined reliability engineering and material development for theimprovement of sonar submaries. The program led to generations of improved sonar systems, as well as insight to the thermodynamics of the oceans. May 23rd 1990 Proclamation: TRI Day in Austin Proclaimed Texas Research Institute/Austin Inc. Day in Austin by Mayor Lee Cook.Recognized for the strong scientific and engineering technology base and considerablecontributions of TRI/Austin to the Austin Community.
