A quadrilateral distance module may be used to detect faults in an electrical power system. The attachment structure includes a bracket secured above the vehicle to the auxiliary frame. The thin wall steel core allows for relatively faster warm up times compared to conventional fusing systems. Thus, the non-solid state storage devices serve as a mirror backup copy of the data stored to the solid state storage devices. According to one exemplary embodiment, a method is provided wherein information is encoded by one or more partial or complete gaps in a line associated with a form, and the line gaps are patterned to provide N-bit codes. The controller is configured to modulate the FOV at a periodic interval, using a sinusoidal waveform, a pulse code modulated waveform, or a pseudo-random waveform.
