The invention relates to a closure system for containers comprising a threaded plug and the neck of the container or the similar embodied in the form of an pouring aperture, the threaded plug being screwed on the neck in such a way that said pouring aperture is closed. The tightening mechanism includes a lever pivotable about a fixed pivot point to convert a portion of the tension to reduce the loosening, and a variable control mechanism positioned proximate the lever for limiting pivotal movement of the lever. A variety of action input devices may be implemented to receive a variety of different action inputs, including, but not limited to, motion-based inputs, touch-based inputs, visual inputs, or audio inputs. For a portion in which illumination compensation is enabled according to the extracted flag information, a value associated with a segment within the portion is extracted from the bitstream and it is determined from said extracted value whether illumination compensation of the segment is to be performed. In one embodiment, the present invention relates to a solid-oxide fuel cell for generating electrical energy from a carbon-based fuel, and to catalysts for use in a solid-oxide fuel cell. The unit converts the format of the data in the video recording system into one in the video system.
