The invention relates to an actuator for operating a positioning element. The resin component and hardener component are mixed and applied to substrates, or applied to substrates and mixed, and then allowed to cure yielding a cured epoxy resin having a tensile elongation at room temperature of greater than 30%. The method enables a processor to accurately and quickly determine which answers were entered on each questionnaire page attached to the capture device, without relying on the user to do so. While exiting the hibernation mode, the volatile system memory is powered and a pre-hibernation state of the volatile system memory is restored. Certain embodiments include control logic to persuade user interaction with the first through third logic to a sequence of interactions within a predefined set of interaction sequences, wherein the predefined set of interactions define an archetype process for user thinking about the problem. The signal conversion unit extracts a \u2202A\u2202t component irrelevant to a flow velocity of the fluid and a v\xd7B component originating from the flow velocity of the fluid from a resultant electromotive force of an electromotive force \u2202A\u2202t, with A, t, v, and B respectively representing a vector potential, a time, a flow velocity, and a magnetic flux density.
