A row crop header for a harvester having a subframe removably coupleable to a feeder housing of the harvester. This is achieved by generating a self-interference term, ICIk\u2212L,k\u2212L, for a signal received on sub-carrier k\u2212L, wherein L \u2208. A first region and a second region on the first substrate have different alignment directions due to a photosensitive alignment film formed on the first substrate. The dielectric layer may include one or more colorants so that important properties of PDP such as selective brightness of desired color, color temperature, and color purity improvement can be controlled. The processor reads the different trip settings from the adjustable rotary switches and communicates the different trip settings through the communication channel to the circuit breaker trip unit.
