A receptacle closure device includes a receptacle having an open upper end, and a closure having a top wall and a marginal flange portion bent downwardly from the top wall for engaging onto the upper end of the receptacle. The device may be a flash media memory card or other conveniently sized, portable storage device. The advertisements are viewed one-at-a-time in a linear manner through use of a common graphical navigation interface, which surrounds the advertisements. The system may be used to back up a more expensive object-redundant storage system. In the black-and-white display mode, the white state is achieved from the metal reflection in the cholesteric planar texture area; and the black state is obtained by cholesteric’s depolarization effect and polarizer’s filtration effect in the cholesteric focal conic texture area. The invention also concerns an adjustment system for a motor vehicle seat comprising such a transmission device.
