System and method for real-time, automatic, recognition of large time-scale driving patterns employs a statistical pattern recognition framework, implemented by means of feed-forward neural network utilizing models developed for recognizing, for example, four classes of driving environments, namely highway, main road, suburban traffic and city traffic, from vehicle performance data. The M cancellation subcarriers are scaled with a generally complex weighting factor. An open ended leaf spring element is mounted inside the maneuver ring and pre-tensioned to embrace the outer surface of the housing, thereby forming a releasable arresting means for the maneuver ring. The emulsions of the invention may further include a saponifiable wax substitute for montan wax.
