An electric-motor furniture drive includes a power supply device, a manual control for moving movable furniture components relative to each other, and an electric motor with reversible rotation direction. The guide surfaces extend between a circumferentially first end portion and a second end portion of the notch and have a curvature substantially equal to that of the outer circumferential surface of the impression cylinder. A second network apparatus determines a type of response frame according to a reception mode of the data frame. The system further includes a resisting member coupled to a louver located at a lower end of the plurality of louvers, the center of gravity of the louvers with the offset axis pulling against the resisting member to maintain tension in the collapsible linkages. The process of filling the vias and trenches involves use of a silicon nitride film as an etch stop and the filling of the vias with an anti-reflection coating. The independent sensory cue delivery means can provide an independent sensory cue selected from the group consisting of vibration, heat, cool, skin irritation, tingling, fragrance or auditory.
