    摘要： A user terminal, an image display device, and a method for adjusting a light source thereof, are provided. A user terminal is connected with an image display device and comprises a first interface unit which receives a color coordinate of an ambient light; a second interface unit which receives a color coordinate of an internal light source of the image display device; and a control unit which calculates a luminance value from the received color coordinate of the ambient light and the received color coordinate of the internal light source, and transmits the calculated luminance value to the image display device via the second interface unit. The image display device adjusts the internal light source of the image display device based on the calculated luminance value. Thus, the light source of a backlight unit can be adjusted based on the ambient light.

    摘要： Audio data decoded in an MPEG system to be stored in a storage unit is supplied to an audio output via a filtering processing. For performing the filtering processing, presentation time interval of respective audio data is changed to conform to a user's designated playback speed, and the decoded audio data stored in the storage unit by being synchronized with the changed presentation time interval is written on an input queue in the set unit. A TSM algorithm is performed in the frame unit with respect to the audio data of the input queue to decrease the quantity of the audio data when the designated playback speed is faster than a normal playback speed or to increase it when the designated playback speed is slower than the normal playback speed, in accordance with a value of the designated playback speed. The TSM audio data is transferred to a middle queue. With respect to the audio data of the middle queue, up-sampling or down-sampling is performed in accordance with the value of the designated playback speed. The quantity of the audio data after the sampling becomes substantially the same as that of the decoded audio data, and thus the sampled audio data have a tone substantially identical to that of the normal playback speed and are transmitted to an output queue. The audio data stored in the output queue is synchronized with the changed presentation time interval to be transmitted to the storage in the set unit, and then is reproduced via an audio output.

    摘要： The present invention relates to a solar powered cathodic protection system using a photocatalyst which functions as a non-sacrificial photoanode under sunlight, wherein said non-sacrificial photoanode consisting of the photocatalyst such as TiO2 (or ZnO) and an electrolyte, is galvanically connected to a metal structure to be protected and continuously provides electrons to the metal structure, whereby the metal structure is protected from the corrosion. The solar powered cathodic protection system using a non-sacrificial photoanode according to present invention is advantageous in that 1) an external power supply is not necessary, 2) it is easy to maintain the system because the non-sacrificial photoanode according to the present invention can be installed outdoors, and 3) the photocatalyst used as the non-sacrificial photoanode is inexpensive and semipermanent.
