Abstract:
A method of manufacturing a colorless transparent polyimide film having reinforced glass fabric for flexible displays, suitable for use in increasing optical transmittance of a polyimide substrate having reinforced glass fabric for flexible displays. This method enables the glass fabric and the colorless transparent polyimide film to be matched in refractive index when the glass fabric is reinforced in the colorless transparent polyimide film to enhance thermal and mechanical properties of a substrate for flexible displays, thus satisfying high optical transparency and optical transmittance of 85% or more, required of a substrate for flexible displays, and thereby the colorless transparent polyimide film having reinforced glass fabric can be used as a substrate for flexible displays.

A bio-inspired algorithm based P2P content caching method and system for mesh networks is provided. The bio-inspired algorithm based P2P content caching method for mesh networks includes the steps of checking a request of a content of a user in a mesh router, and searching the content from the mesh router, which is requested for the content, based on a bio-inspired algorithm.
Abstract:
The present invention couples a housing including a gas separation membrane to a sensor unit capable of detecting the concentration of hydrogen gas such that liquid cannot permeate a closed space within the housing and only hydrogen gas dissolved in the liquid can permeate the closed space through the gas separation membrane, and detachably couples such a hydrogen sensor element to an opening of a container in which the liquid is held. Accordingly, the present invention can measure the concentration of dissolved hydrogen gas in a simple manner.
Abstract:
Provided is a near field wireless communication apparatus that uses magnetic coupling and a method for operation of the apparatus, in which the magnetic coupling is used to transmit data or clock information with low power and high efficiency. A pulse generator of the near field wireless communication apparatus generates a pulse signal corresponding to transmission digital data to be transmitted. When the transmission digital data is “1,” the near field wireless communication apparatus modulates the data into the pulse signal and transmits the pulse signal. When the data is “0,” the near field wireless communication apparatus does not output the pulse.
