Abstract: A technique including accessing data to control permissions assigned to a given role for a computer system. The data assigns the given role with a role template and an environment template, wherein the role template defines at least one action that can be performed with the system, the environment template defines at least one resource of the system that can be accessed, and the role and environment templates are independently assignable to at least one other role. The technique includes controlling access to the system based on the data.

Abstract: An internal combustion engine that replaces the throw journal of a crankshaft with a set of contours that are dynamic rather than static. The contour is such that three cycles of engine operation are not affected, i.e., exhaust, intake, and compression. The contour deviates only during the power stroke where an increased incidence to the circular is incorporated. This defers from previous attempts by eliminating complex geometries such as epitrochoidal or sinusoidal that by their nature negatively affect the exhaust, intake, and compression strokes of the Otto cycle when compared to the traditional crankshaft. Additionally, the deviation from the circular orbit during the power cycle optimizes to a larger extent the leverage available for peak thermodynamic pressures in the cylinder in the brief optimum time afforded by that pressure.
