An intellectual non-invasive anesthesia machine monitoring system is analyzed in this paper. The system consists of a data acquisition terminal, a communication module and a PC/104 monitoring platform. The data acquisition terminal detects the real-time parameters including tidal flow, airway pressure and oxygen concentration. These parameters will be transmitted to the monitoring platform through serial ports for records and analysis. In this way, the flow, pressure and concentration of the medicine can be controlled for the general anesthesia on the patient. With advantages of intuitive alarm signals, safe and reliable environment, and complete function, the system also realizes the expert diagnosis by xmlhttprequest and Server-Sent Events technology. After repeated validation test, the system can work steadily and will have a wide application prospect in the market.

In this paper, the development model and system architecture of WebGIS application based on Ajax is introduced. Combined with the platform of SuperMap ***, the developing method for WebGIS application is discussed in detail. By utilizing the technique of Ajax, the problem existed between Server and Client can be effectively solved, and the asynchronous interaction between Browser and Server is easy to be implemented. As a consequence, redundancy is decreased to enhance the Server performance.

X3D supports a variety of media types to be used in 3D scenes, like images, videos or other X3D models. A scene can dynamically load and replace this media during runtime, but since there is no way to communicate directly with outside sources like a server, all data sources need to be known in advance. This problem is usually solved by using interfaces like SAI, which allow external applications to modify the current scene. But this solution makes it necessary to set up all the communication via SAI and have the external application communicate with a server. In this paper, we will show how xmlhttprequest, an object common in web browsers, can be used to handle the communication from within the X3D Browser. We will show how well this approach fits into the X3D environment and how easy this can be implemented in an X3D Browser. Afterwards, some examples will show the benefits in real applications and how easy this solution is to use.

Ajax is really several technologies, each flourishing in its own right, coming together in powerful new ways, which consists of HTML, JavaScript (TM) technology, DHTML, and DOM, is an outstanding approach that helps to transform clunky Web interfaces into interactive Ajax applications. After the definition to Ajax, how to make asynchronous requests with JavaScript and Ajax was introduced. At the end, advanced requests and responses in Ajax were put forward.
