Provided are compositions comprising a superhydrophilic amphiphilic copolymer and a carrier and composition comprising a superhydrophilic amphiphilic copolymer, a micellar thickener and a carrier. A transform is then derived between the first image encoding values and the second image encoding values. The outputs of the voltage regulator are controlled to provide voltages that are optimized with respect to temperature for the integrated circuits in the optical module.
