Apparatus and methods of determining configurations for handling communication path management traffic are disclosed. For example, according to one representative embodiment, an apparatus for reducing NOx emissions in an engine exhaust includes a NOx reduction target module that is configured to determine a NOx reduction requirement that includes an amount of NOx in the exhaust gas stream to be reduced on a selective catalytic reduction catalyst. The device may determine a location in the message that corresponds to the information regarding the edit and may determine a particular quantity of characters associated with the information regarding the edit. The apparatus includes a multiplexer, the multiplexer to multiplex the on screen display data into the input stream. In addition, the system can include an intra-operative real time analyzer configured to measure and display topography and aberrometry information related to a patient’s eye for assisting in proper implantation of the IOL. The field effect transistor is capable of enhancing a carrier mobility.
