Wireless application protocol (WAP) (Open Mobile Alliance, 2003) is a suite of network protocols that specifies ways of sending data across the airwaves. A wireless device is said to be WAP-compatible if, and only if, it has software that is fully capable of handling all WML 1.1 DTD entities. WML (Wireless Markup Language) (Open Mobile Alliance, 2001) is the XML-based language that is used in conjunction with WAP to format documents. As with all such protocol suites, WAP is organized hierarchically. At the bottom there are low-level protocols that are used for basic operations such as establishing connections, coding alphanumeric characters, and so on. At the top are the high-level protocols such as WML, which passes on page information. For more information on other WAP protocols, please visit http://www.wapforum.org/. WML script writing and applications will be discussed in Chapters VI through IX: • Chapter VI: The current chapter introduces fundamental WML components such as tables and images. • Chapter VII: Advanced WML, especially dynamic WML pages using CGI (Common Gateway Interface), will be introduced. • Chapter VIII: WMLScript, a lightweight JavaScript language used in conjunction with WML, is explained. • Chapter IX: The construction of a database-driven mobile web site using WML is explained step-by-step.

Abstract We have developed a Web-based interactive cam design package under the programming paradigm of the CH language environment. This package was initially developed as a teaching and learning tool for educational use in an undergraduate Computer-Aided Mechanism Design course. Because the system is Web-based and implemented through a client/server model with the user interface through the Web browser, it is easy to use and maintain. The system can also be used to solve practical engineering cam design problems with two follower motion types of translation and oscillation. The system can be used to generate cam profile, position, velocity, and acceleration histories of the follower. Once a cam/follower system is designed, animation of the cam/follower system can be performed. At the end of the design, the CNC code for manufacturing the designed cam can also be produced through our Web-based cam design system. The package consists of a number of modules including various Web pages, common gateway interface (CGI) programs, and a CH program called cam which performs the necessary computation for cam design. Two different versions of the cam design package have been designed and implemented. One runs the cam design program on the client machine as a CH applet, and the other runs the cam design program on the Web server though CGI. In this paper, details of design and implementation of Web-based cam design package will be described. Two application examples with different motion types for the follower will be used to illustrate features of the applet-based and CGI-based implementation schemes.

At present the application layer in the network data transmission and expression of the most widely used protocol is Http protocol, embedded devices through the Internet network remote monitoring of data transmission direction to one of the main focus in the Web server for embedded systems. Embedded web server to achieve this, no operating system support, embedded system itself Common Gateway Interface, to complete web page publishing, the most important is the use of embedded devices that can be used as remote monitoring software system.The key equipment for the motor system for remote network monitoring, this paper describes the design of the specific structure of web servers and for system implementation and realization of the key technologies used to give a detailed exposition, in the end PC to run on the results of the test.

The Internet and World Wide Web (WWW) are now evolving as an important communication technology and a major information resource provider for industry. This paper discusses the development and implementation of a knowledge-based gear design and manufacturing system over the Internet to create new integrated design and manufacturing environments. By providing access to an interactive web-based support system, any designer with a WWW browser becomes a potential user of this on-line design system. Once connected, the designer follows the system instructions and submits the necessary input data on the appropriate web pages. The server receives a request from a client and invokes a CGI (Common Gateway Interface) program that processes the information provided through the user Interface. The CGI parses the data and has the ability to remotely run the knowledge-based gear design system that integrates knowledge about all aspects of gear design and manufacturing and provides powerful reasoning and decision-making capabilities for reducing the time between gear tooth creation, detailed design and manufacturing process specification via the Internet. When the execution is completed, full specifications definition, geometry, kinematic-loads and stresses are determined through Finite Element Analysis (FEA) within ANSYS, VRML models of the gear pair and gearbox assembly including gears, shafts, bearings and housing are exported according to the designer requests and sent back to designer on the web browser. To accomplish this, a combination of HTML, JavaScript, VRML, CGI Script and C++ is used. Finally, an example on spur gear design utilizing a parallel gearbox design model configuration is discussed.
