The present invention relates to a backlight apparatus used in an LCD, in which upper and lower reflective plates are installed under upper and lower transparent plates, respectively. The lower transparent plates and the lower reflective plates introduce light generated by lower light sources in upward directions and the upper transparent plate and the upper reflective plates introduce light generated by an upper light source into those areas, which are not lighted by the lower light sources. This can prevent the formation of dark areas above the lower light sources as a problem of a conventional large-sized backlight apparatus, thereby enhancing the overall uniformity of light. In this way, the backlight apparatus of the invention can be designed thin even when applied to a large-sized LCD.

This disclosure relates to methods for monitoring a database system without access to the database system, wherein when data packets between a plurality of operating servers including the database system and a plurality of client application processes are sent and/or received through a SQL net protocol or BEQ protocol, the data packets are collected through sniffing by a monitoring process or through a separate pipe gateway process thereby SQL information and database performance information transmitted between the operating servers and the client application processes are extracted. The SQL information and database performance information can be effectively monitored with no load or minimized load to the database, operating server and network.

A mobile terminal device and method are provided for displaying remaining battery capacity. The device and method comprise internal and external batteries installed on the mobile terminal, a display unit displaying remaining battery capacity, a battery detecting unit identifying whether the external battery is additionally installed, a remaining battery capacity measuring unit measuring total recharged voltage of the internal and external batteries and a control unit displaying the total remaining battery capacity on the display unit corresponding to the measured total recharged voltage. Accordingly, a user may identify installation of the external battery more easily and avoid confusion due to rapid display changes in remaining battery capacity displayed as a recharged voltage difference between the internal and external batteries.

Provided are a coded block pattern (CBP) estimating method which is performed using an average value and a dispersion value between blocks of CBPs in a moving picture encoder for IP-TVs (Internet Protocol-Televisions), and a block mode decision method, which can determine all block modes with only the first 16×16 block. Accordingly, since an additional operation for mode determination is not necessary, an amount of calculation and thus a calculation time can be remarkably reduced.

The invention provides a method for fabricating a superlattice semiconductor structure capable of achieving excellent interfacial properties and uniformity. For the superlattice semiconductor structure according to the invention, a substrate is mounted on a susceptor within a process chamber. First and second source gases are supplied simultaneously to two different areas on the susceptor within the chamber to form first and second source gas areas separate from each other. The susceptor is rotated to revolve the substrate through the first and second source gas areas.

The present invention relates to a high-power single-mode semiconductor laser device, in which a first conductivity-type cladding layer is formed on a semiconductor substrate. An active layer is formed on the first conductivity-type cladding layer, and a second conductivity-type cladding layer is formed on the active layer, with a ridge protruding upward. The invention has corrugated parts formed on upper surfaces of the second conductivity-type cladding layer on both sides next to the ridge for scattering light in order to suppress high order mode oscillation.

The invention relates to a backlight apparatus in use for an LCD, in which a plurality of bar-shaped first LED light sources are arranged on the reflective plate to laterally emit light. A plurality of light shades are arranged above the first light sources. A transparent plate is placed above the light shades. Scattering patterns are formed in the bottom of the transparent plate in positions corresponding to the light shades. A bar-shaped second LED light source is arranged at a side of the transparent plate to emit light into the transparent plate. The light source arranged at the side of the transparent plate prevents the formation of dark areas as a problem in the prior art, thereby enhancing the entire uniformity of light. Then, the backlight apparatus can be maintained thin even when applied to a large-sized LCD.
