Satellite communications technology is a tremendous force for change and innovation. From the first satellite telephone call, to the moon landing in 1969, to today's global coverage of the Olympics with more than 3 billion viewers, satellites have helped create a world community. From $300trillion annually in worldwide electronic funds transfers to hundreds of millions of airline reservations, satellites play critical roles in finance, business and international trade. Despite growth in fiber optic cables, some 60% of all overseas communications is satellite based. Today, more than 200 countries and territories rely on about 200 satellites for domestic, regional and/or global linkages, defense communications, direct broadcast services, navigation, data collection, and mobile communications. Satellite communications is the largest and most successful of all commercial space enterprises-it is currently a $15 billion per year business which could grow to $30 billion per year within the decade.

In the mid-1960s, when satellite communications first became a commercial reality, the United States was not just the leader, but was predominant in every aspect from launch vehicles to satellite technology. The agreements under which the International Telecommunications Satellite Organization (INTELSAT) were established were originally negotiated on an interim basis only, giving the United States a dominant leadership role. Japan and Europe felt they would need a number of years to enter seriously into the field. Today, more than a quarter of a century later, conditions have changed dramatically.

The focus of this study is on experimental and advanced technology being developed in R&D anddemonstration programs rather than on today's production capabilities. The report focuses on commercial satellite technology, and does not review defense-related or other confidential satellite communications capabilities. The NASNNSF panel concluded that the United States has lost its leading position in many critical satellite communications technologies.

The book can be seen as a "toolbox" includingg all the necessary hardware and software information to be used in constructing 8051-based controller systems.

This completely revised edition remains the only comprehensive treatise on polymer coatings for electronics. Since the original edition, the applications of coatings for the environmental protection of electronic systems have greatly increased, largely driven by the competitive need to reduce costs, weight and volume. The demands for high-speed circuits for the rapid processing of signals and data, high-density circuits for the storage and retrieval of megabits of memory, and the improved reliability required of electronics for guiding and controlling weapons and space vehicles have triggered the development of many new and improved coating polymers and formulations. Both the theoretical aspects of coatings (molecular structure of polymer types and their correlation with electrical and physical properties) and applied aspects (functions, deposition processes, applications, testing) are covered in the book. Over 100 proprietary coating formulations were reviewed, their properties collated, and tables of comparative properties prepared. This book is useful as both a primer and as a handbook for collecting properties data.

This handbook is a broad review of semiconductor materials and process technology, with emphasis on very large-scale integration (VLSI) and ultra large scale integration (ULSI). The technology of integrated circuit (IC) processing is expanding so rapidly that it can be difficult for the scientist working in one area to keep abreast of developments in other areas of the field. This handbook solves this problem by bringing together "snapshots" of the various aspects of the technology.

This book introduces contamination control in a comprehensive manner. It covers the basics for the beginner, and delves in depth into the more critical issues of process engineering and circuit manufacturing for the more advanced reader. The reader will begin to see how the puzzle of contamination control comes together and to focus on the fundamentals required for excellence in modern semiconductor manufacturing. What makes the area of contamination control unique is its ubiquitous nature, across all facets of semiconductor manufacturing. Clean room technology, well recognized as a fundamental requirement in modern day circuit manufacturing, barely scratches the surface in total contamination control. This handbook defines and describes most of the major categories in current contamination control technology.

Recent technological advances have created a "testing crisis" in the elctronics industry - smaller, more highly integrated electronic circuits and new packaging techniques make it increasingly difficult to physically access test nodes. New testing methods are needed for the next generation of electronic equipment and a great deal of emphasis is being placed on the development of these methods,. Some of the techniques now becoming popular include "design for testability" (DFT), "built-in self-test" (BIST), and "automatic test vector generation" (ATVG). This book will provide a practical introduction to these and other testing techniques. For each technique introduced, the author provides real-world examples, so the reader can achieve a working knowledge of how to choose and apply these increasingly important testing methods.
