A method includes operating a hybrid power train having an internal combustion engine and an electrical torque provider. Current industry practice is to uniformly add slots to wide and long copper interconnect lines, this to achieve improved CMP results. The apparatus and methods may be configured to map color coordinates differently depending on whether or not a pixel corresponds to a light source in an image andor has special or reserved color values. In some embodiments, the companion appliances are capable of simultaneously exchanging voice and data messages with devices connected to the network.
