Short Content: At present, hot spot CTI (computer telephone integration) applies has the media gateway, the IP telephone, the IP facsimile and so on. Sometimes the soft exchange is called calls the server or the media gateway controller. The soft exchange's basic concept is (media gateway) separates the call control function from the transmission level. Realizes the basic call control function through server's on software, like call routing, supervisory control, signaling intercommunication. Because controls the call and calls transmits separates, for the ...

Short Content: O introduction    Switching power supply toward high efficiency, high stability, high power density, low pollution, modular development. Each kind of new analysis situs electric circuit and the technology also obtained the application. Resonant and the soft switch technology's application also causes the mains input density to be able to enhance. The power source controls, the control circuit, the driving circuit, the protection circuit used integrate the module to reduce power source's design difficulty. High speed microprocessor DSP (Digital Signal Processing ...

Short Content: The biological modelling machine crab control system needs the high control precision and the operating speed, in order to the mechanism rigidity high situation, through the enhancement speed of response guaranteed that the robot walks normally with the attitude control. Because sets in the machine crab thigh and the tibia has two electrical machinery (as shown in Figure 1), causes its quality to be big, because simultaneously the volume limit causes each walk foot mutual spacing to be small, will ...

Short Content: The video frequency terminal's core is the image digitization processing module. Based on the PC machine digital video processing, has given the algorithm research way, but has only then provided the real-time embedded video processing possibility based on the high speed DSP application module. However, based on the DSP magnanimous video data's real-time processing's key is real-time, reasonable video data gathering. This article in view of independently develops (hereafter refers to as DM642) based on TMS320DM642 the DSP video processing ...

Short Content: Along with our country electric power enterprise's fast development, the electrical power system to sent, loses, matches, electricity consumption gathering also to have a higher request. Electric quantity gathering takes the electrical power system real-time control, the monitor, the dispatch automation premise link, has the vital role without a doubt. But in electric quantity gathering process, because has disturbance factors and so on overtone, therefore how is accurate, gathers in electrical power system's each simulation quantity has been in electrical ...
