Multiplexing an additional bit stream with a primary bit stream, where the primary bit stream is encoded into an xByB encoded bit stream, involves selecting yB code-words to convey the additional bit stream. The method includes intercepting a communication, identifying sensitive data in the communication and transmitting data to an anonymization engine for masking. The imaging element may be used for printing long run lengths on lower quality paper and in the presence of set-off powder. In addition, resource allocation and predictive performance monitoring engines allocate resources and monitor the resources allocated to the services accessing the service cloud. The operation of the actuator is controlled in response to the detected power demand so as to increase or decrease the engine, and ignition timing of the engine is controlled in a retard direction in response to the detected thermal demand. Another aspect of the method relates to using a shadow mask comprising ribs which, in an angled evaporation method, can correct for parallax.
