Uninterruptible power supply system

Abstract: In an uninterruptible power supply system, control sections of three uninterruptible power supply units are connected to one another by communication cables to configure one integrated control unit The integrated control unit brings three switches into conduction if a bias feeding mode is selected by one arbitrary operation section and brings three switches into conduction if an inverter feeding mode is selected Therefore, there is no need to separately provide an operation section and a control section for operating and controlling all of the uninterruptible power supply units

Wireless communication system, wireless terminal station, wireless base station, and wireless communication method

Abstract: A first wireless terminal station transmits beam transmission direction identification information in all directions. A second wireless terminal station receives the transmission direction identification information, combines reception direction identification information and the transmission direction identification information, and transmits directivity direction combination information to a wireless base station. The first and the second wireless terminal stations form directional beams in directions indicated by the directivity direction combination information to thereby perform a direct communication.

Method and system for synthesizing multiview videos

Abstract: A system and method synthesizes multiview videos Multiview videos are acquired of a scene with corresponding cameras arranged at a poses such that there is view overlap between any pair of cameras A synthesized multiview video is generated from the acquired multiview videos for a virtual camera A reference picture list is maintained for each current frame of each of the multiview videos and the synthesized video The reference picture list indexes temporal reference pictures and spatial reference pictures of the acquired multiview videos and the synthesized reference pictures of the synthesized multiview video Then, each current frame of the multiview videos is predicted according to reference pictures indexed by the associated reference picture list during encoding and decoding

3D graphics LSI core for mobile phone "Z3D"

Abstract: In this paper we describe the architecture of the 3D graphics LSI core for mobile phone "Z3D". The major 3D graphics applications on mobile phones are character animation and games. While a character animation or a game is running, the CPU has to be used for the communication to the center machine and CPU clock frequency is low. Therefore, the requirement of Z3D is small, low power, and CPU free. The pipeline of Z3D is composed of a geometry engine, rendering engine, and pixel engine. Generally, these modules run in pipeline on PC, but running in pipeline, power consumption rises. We used gated clock control for low power consumption and having the pipeline work in sequential, we could reduce 40% of the power consumption with 10% performance decreasing. The geometry processing performance of Z3D is up to 185Kvertex/sec and the pixel performance is 5Mpixel/sec. This performance is enough to have character animations and games run. The data of 3D shape and animation can be defined using common 3D modeler and contents program can be described by Java. Low level rendering interface and animation rendering interface are provided as a Java API. All the contents programs can be downloaded from network.

Progress in soft-decision FEC

Abstract: We discuss the practical implementation of LDPC codes in soft-decision FEC for 100 Gb/s digital coherent systems. The question of the definition of net coding gain for differential QPSK used to avoid cycle slip is raised.
