  • Patent number: 8658399
    Abstract: Disclosed herein is a novel gluconacetobacter strain having cellulose producing activity. Specifically, the present invention relates to a novel gluconacetobacter strain producing nano-structured cellulose in a highly efficient manner. The cellulose produced by the strain, due to its superb thermodynamic properties, can be characterized as nano-structured bacterial cellulose and therefore utilized as a bio-nano-fiber. Particularly, the cellulose can be impregnated with a resin to form a cellulose-based resin which can be effectively adapted for a substrate for a liquid crystal display (LCD).

  • Publication number: 20130069436
    Abstract: An apparatus configured to control power off in an apparatus includes a power unit, a battery detachment detector, an input unit, and a controller. The power unit supplies power from at least one of a battery and an auxiliary power unit. When detecting that the battery is separated from the power unit, the battery detachment detector outputs a battery separation signal to the input unit using power from the auxiliary power unit. When receiving the battery separation signal from the battery detachment detector, the input unit generates a power off event using power from the auxiliary power unit. When the power off event occurs from the input unit, the controller performs a power off procedure using power from the auxiliary power unit.
