摘要:
The present invention relates to an emulator module of a computer which controls an input/output process of a communication terminal via a peripheral device interoperating with the computer, and more particularly, to an emulator module of the computer and a method of operating the emulator module which control either a first control signal, transmitted from the peripheral device, to be converted into a second control signal according to a protocol supported by the communication terminal, and to be transmitted to the communication terminal via a communication module of the computer, or a first control signal, received from the communication terminal, to be converted into a second control signal according to a protocol, supported by the peripheral device, and to be transmitted to the peripheral device.

Disclosed is an optical transmission system capable of transmitting optical signals of E-band and other bands through one optical fiber. The system includes a first thin film filter for receiving optical signals of E-band and other bands at both sides thereof respectively, and multiplexing the optical signals of both E-band and other bands by selectively transmitting wavelength ranges received at one side, reflecting wavelength ranges received at the other side, and then coupling the optical signals of both E-band and other bands; an optical fiber for transmitting the optical signals multiplexed by the first thin film filter to a receiving portion; and a second thin film filter for selectively separating and demultiplexing the E-band and other bands from the optical signals transmitted through the optical fiber.

An improved water turbine which has a first rotatable cylinder having a water inlet hole and a plurality of nozzles, and a second rotatable cylinder having a plurality of rotating blades on the inner surface is disclosed. Water dropped from an altitude enters the first rotatable cylinder through the water inlet hole, where it is injected to the outside of the first rotatable cylinder causing the first rotatable cylinder to rotate. Water passing through the nozzles then strikes the rotating blades to rotate the second rotatable cylinder.

The present invention relates to a user interface server framework and a method of using the framework, which supports a user interface developer to develop a final user interface based on components. The component-based web application development framework used for creating a web page comprises a runtime engine for executing a method of a business object and returning a result of executing the method in response to a user's request; a script component for performing a preprocessing on a user input value before executing the method of the business object, performing a post-processing on the result of executing the method after executing the method of the business object, and dynamically arranging a user interface object; and a core component for initializing the framework and confirming whether the user's request can be processed in the framework.
摘要:
Disclosed is a low-attenuation single-mode optical fiber having a photoconductive core and a clad, which shows very low OH concentration in MFD (Mode Field Diameter) region. The optical fiber includes a core positioned at its center for photoconduction, and a dehydrated clad and a base clad which are coated on the clad in order. The dehydrated clad has a substantially identical refractive index to the base clad. A refractive index of the core is greater than those of the dehydrated clad and the base clad. The dehydrated clad has a relatively lower OH concentration than the base clad. The region composed of the core and the dehydrated clad has an MFD region at which OH concentration is less than 0.8 ppb.
