摘要:
A screen display method and apparatus of a mobile terminal is provided for changing a screen represented by an index to another screen represented by a newly selected index. A screen display method of a mobile terminal includes displaying a page represented by an index, the page including an index region having a plurality of indices and a content region displaying content corresponding to the index highlighted in the index region, selecting a new index in the index region according to a selection input, and changing the page represented by the highlighted index for a new page represented by the new index, the new page appearing in a direction from a position of the new index to a position of the highlighted index.

A lithium secondary battery includes: a first electrode having a first current collector, and first active material patterns formed on the first current collector such that the first active material patterns are symmetrically disposed with a first center non-coated portion formed therebetween; a second electrode having a second current collector, and second active material patterns formed on the second current collector such that the second active material patterns are symmetrically disposed with a second center non-coated portion formed therebetween; a first electrode tab connected to the first center non-coated portion; and a second electrode tab connected to the second center non-coated portion.
摘要:
Provided is an apparatus for an optical clock extraction, which is capable of providing high optical amplification rate and more efficient noise cancellation by using a Fabry-Perot (FP) filter and an optical amplifier. In the apparatus, an optical circulator changes a direction of an inputted optical signal. The FP filter extracts different frequency components existing on a spectrum of the inputted optical signal and being spaced apart by a clock frequency, removes noise from a reflected and amplified optical signal, and transmits the resulting signal to the optical circulator. An optical amplifier performs a primary amplification to equalize two different frequency components outputted from the filter, and performs a secondary amplification on an optical signal reflected and fed back thereto. A reflector reflects the primarily-amplified optical signal to the optical amplifier.
