Abstract: A DC power plant generating DC power from a variety of engines including a Stirling cycle engine. The DC power plant includes a relatively small start-up power source that is discontinued after the engine is running. A method for producing DC power for a load including starting up an engine using power supplied by a relatively small power supply supplemented by a capacitor bank, providing output from the engine to a generator, producing alternating current (AC) power by the generator, converting the AC power to direct current (DC) power, disabling output of the DC power during a first set of pre-selected conditions, limiting a rate of change of current of the DC power during a second set of pre-selected conditions, reducing conducted and radiated emissions of the DC power, disconnecting the DC power from the load under a third set of pre-selected conditions, and providing the DC power to the load.

Abstract: A boundary definer or data processor establishes an outer boundary of a work area and defines an offset between an inner boundary and the outer boundary. A reference path module or data processor defines a primary reference path with a target angular heading within the work area. The reference path module or data processor generates secondary reference paths spaced apart from and generally parallel to the primary reference path. An incident angle estimator estimates an incident angle of incidence of the vehicle with the outer boundary. The former or data processor establishes an inner boundary point spaced apart from the outer boundary by the offset and coextensive with a corresponding one of the reference paths. Further, the former or data processor interconnects the established inner boundary points to form the inner boundary.
