An organic light emitting device structure having an organic light emitting device over a substrate, where the OLED has, for example, an anode, a hole transporting layer, a first electron transporting layer that is doped with a phosphorescent material, a second electron transporting layer, and a cathode. The invention uses a combination of color codes or other indicators and a combination of algorithms andor rules-based systems to control the computation of statusseverities to associate to components and setup the color codes and indicators. The ultrasonic return signals are heterodyned into the audio spectrum for purposes of audio detection. Additionally, the present inventions provide a range of surface and near-surface processing methods to enhance spall and ejecta from conventional munitions systems, enhancing munition breakup and reactivity as well. The invention also provides pharmaceutical compositions comprising such compounds, methods of using such compounds to treat diseases associated with 5-HT4 receptor activity, and processes and intermediates useful for preparing such compounds. The modified colored pigment comprises the product of a colored pigment having at least one leaving group and a treating agent.
