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.

Abstract: In the case of a pipelined processor, a performance gain is achievable through dynamically generating a main clock signal associated with a synchronous logic circuit and generating at least one backup register clock signal, the backup register clock signal at the same frequency as the main clock signal and phase shifted from the main clock signal to thereby provide additional time for one or more of the logic stages to execute. Error detection or error recovery may be performed using the backup registers. The methodology can further be extended, to design a system with cheaper technology and simple design tools that initially operates at slower speed, and then dynamically overclocks itself to achieve improved performance, while guaranteeing reliable execution.
