Methods of and systems for illuminating objects using planar laser illumination beams having substantially-planar spatial distribution characteristics that extend through the field of view of image formation and detection modules employed in such systems. A microprocessor, coupled with the touch screen assembly, reads the manually drawn path and controls movement of the vehicle to follow the manually drawn path. The film is exposed to patterned radiation. The receiver may determine a noise power value of the signal received from the plurality of antennas using unoccupied orthogonal frequency division multiple access tones of a first preamble included in the super-frame of the signal, wherein the first preamble includes carrier information. The RPCVD produces a partially crystalline germanium first layer.
