The basic principle behind this process relates to the use of training technologies to classify the transitions between Technology Life Cycle stages for each test technology considered. Based on the evidence of Hanna and Gao \cite{hanna2015innovation,Gao_2013}, a total of XX training technology profiles were available for this classification exercise, as opposed to the two (Thin Film Transistor Liquid Crystal Displays and Cathode Ray Tubes) used in the original work by Gao. Although different patent databases have been used in this study, the basic patterns observed for the two training technologies employed in Gao's work are mostly captured in the records extracted using the Questel-Orbit tool. This can be seen in Fig. \ref{391527} where the extracted trends are compared against the original study:
