A nasal dilator that includes an upper resilient member for dilating the nasal valve and a lower resilient member for dilating the nostrils. The device, upon the measurement by means of, for example, the moving element to travel the step P, and the basis of selectively predefined numerical values associated through the control circuit with the time T, permits division of the step into a number of n of elementary steps Pn uniformly distributed through the step P, including for high values of the number n. Related systems, methods, and articles of manufacture are also provided. The two sheets are configured so as to have their second ends free when they are attached together in proximity to their first end. It is particularly relevant to linear or rotary motors that have a large air gap, and to small motors that must deliver a high ratio of thrust or torque to motor mass. The method of this example embodiment may further comprise selecting an access method from the third set based at least in part on the attribute values associated with the access method.
