Water-based colorant traced formulations containing one or more water treatment agents, such as phosphonates, polyacrylic acids andor polymers, co-polymers, terpolymers thereof, azoles, molybdate, polysilicates, phosphates, zinc, polyphosphates, etc. A sealing bar assembly includes a sealing bar designed for constant heated operation and a pair of cooling plates which function as heat sinks. The bus interface provides the light element controllers with a general command, and the light element controllers generate light element drive signals on basis of the general command and the light element data. The first dielectric layer disposed on the first surface is filled in part of the cavity and covers part of the electronic device. In response, in one embodiment, the invention includes updating the safety argument of the dangerous instruction, and eliminating the safety check from the intermediate representation during the safety check elimination optimization.
