This technology is a dynamic output compensator that can significantly improve the dynamic response of voltage regulators. The key advantage of the compensation method is that it is not necessary to redesign the power conversion stage and controller existing in voltage regulators. It only requires .....

The invention proposes the adding ay to the insidof a small time-dele differential link of a PID controller. The differential action efficiency is satisfactory when the time delay is little. In case the time delay is large, the differential action work will switch to the proportional control operati.....

This invention aims at enhancing and widening the spatial effect of stereo audio system. Traditional ways of enhancing the spatial effect of a stereo audio system may sound mechanical, and could be affected by external factors such as the auditory characteristics of the listeners. Our method conceal.....

The H.264/AVC standard achieves a much higher compression performance than the present standards of MPEG-1/2/4 and H.261/263. To achieve the highest coding efficiency, the H.264 encoder employs rate-distortion optimization (RDO) techniques to produce the best coding results in terms of both bit-rate.....
