Abstract: A vehicle mounted AC generator system having an AC generator mounted outside the engine/transmission compartment and connected by drive shaft with universal joints and a belt driven RPM ratio device. The ratio is set to provide accurate AC generator RPM at a preselected engine RPM. The AC generator is mechanically engageable when certain conditions are met and is disconnected when other conditions are present, including an operator emergency stop switch.

Abstract: The present invention provides a method and apparatus configured to provide graphical symbols indicative of a separation value between a first and second location, measured from a predetermined reference point. In one embodiment, the separation value relates to at least one of the direct distance between said first and second locations and the angle subtended between said first and second location at the said predetermined reference point. In one embodiment, the separation value may be resolved into mutually orthogonal components. An alpha-numeric display may also be included and configured to represent the magnitude of said separation values.
