We propose to develop a portable thermal imaging diagnostic system that can be used to significantly reduce operating and support costs for both military and commercial vehicles and-most importantly-avoid the tragic consequence and tremendous costs due to injuries or deaths resulting from catastrophic accidents. During Phase I, Radian Inc. will work with its partners to explore two models of software approach and to demonstrate, based on past experience, the feasibility of the models to predict tire failures. EIC Inc. will develop an Empirical Model; Signature Research Inc. will develop a First Principles Model. During Phase I Option, both companies will prepare a Detailed System Design (DSD) for integrating their software into a portable version of the Thermal Imaging Inspection Station (TIIS) developed by Radian. Radian will determine which method, or combination, holds more promise. During Phase II, Radian will research, adapt, and test components while software is written and integrated into TIIS. End product is a prototype portable TIIS capable of predicting tire failures in moving vehicles. Dual-use applications will be explored during Phase III, including incorporation of the prototype into automated test facilities that could be installed in weigh stations and in commercial trucking facilities. A portable tire diagnostic system that can detect faulty or damaged tires on moving trucks has the potential to significantly reduce Operating and Support Cost and to lower the incidence of catastrophic accidents of both military and commercial vehicles. For commercial use, the system could be incorporated into automated test facilities installed near weigh stations and in trucking facilities.
