It is possible to obtain a polarizing film having a high dichroic ratio by using a liquid-crystalline coating solution in which a small quantity of a second lyotropic liquid-crystalline low-molecular compound is mixed with a first lyotropic liquid-crystalline low-molecular compound. The active region is formed above the substrate and is designed to emit light having a gain peak wavelength. The hardware portion includes a minimum amount of hardware to achieve operations of receiving a RF signal, producing an IF signal and outputting data representing the IP signal. Additionally, an underlying rotation and support structure provides a stable platform for the beam layer when the device is activated. When operating in the automatic centering mode, the header tilt control module compares the centering signal and the balance signal to automatically level the header relative to the frame of the harvester.
