sor-based devices are now produced serially and can be used not only for the automation of debugging the microprocessor technique facilities, but also in the serial manufacturing o f measuring devices with embedded microprocessors and in the reconditioning and maintenance of these devices.

Tektronix 8560 Multi-User System C.C. Smith and P. Versteeg (Tektronix International) began their lecture by noting that t o d a y ' s developers of microcomputer products are faced with a difficult problem: minimizing the cost of developing software for use with sophisticated, low cost microcomputer components with ever increasing processing power. Software sophistication increases as a function of processing power, requiring more experienced design teams, improved coordination, and better software development systems. The existence of more powerful, flexible and forgiving software development tools will, according to Smith and Versteeg, allow these teams to perform their jobs more effectively, thus reducing the cost of software development and maintenance. Software development systems are available in a variety of architectures and a wide range of operating systems. One such system, the Tektronix 8560 Multi-User Software Development System, offers powerful, flexible solution to the software development problem. The 8560's operating system, called T N I X , is based on the U N I X Operating System developed and refined at Bell Laboratories over the past 10 years. Smith and Versteeg outlined the various phases of the software design cycle and demonstrated how the 8560 can increase software development productivity while facilitating software project management.

Pattern Recognition Pattern recognition is the subject of scientists and engineers who set their goal in developing means and methods with which computers will be able to recognize, to process and to interpret information in forms as they are familiar to us, such as text and graphics; images and scenes; voice signals and sounds. This will not just render new capabilities for information processing automats but also an essential contribution to an (almost) natural manmachine-dialogue will be made. Therefore, pattern recognition plays a m a j o r role for the development of future information processing systems. The 6th International Conference on Pattern Recognition, I C P R , took place at the Technische Universitaet Muenchen from October 19 to 22, 1982. The conference was organised by the International Association for Pattern Recognition, IAPR, and the Deutsche Arbeitsgemeinschaft fiir Mustererkennung, D A G M , under the guidance of Prof. Dr.-Ing. H. Marko. The I A P R is an association with 20 national member societies from 15 countries, the Federal Republic of Germany being represented by the D A G M - a study group of 7 G e r m a n scientific societies. Of a series of six this was the first conference to take place in Germany, earlier conferences were held in Washington, D.C. (1973), Copenhagen (1974), C o r o n a d o (1976), Kyoto (1978) and Miami (1980), the next one will be in Montreal, Canada (1984). The Munich conference was sponsored by the Federal Ministry of Research and Technology, the Free State of Bavaria, the City o f Munich, the Technische Universitaet Muenchen, the Gesellschaft ftir Strahlen- und Umweltforschung m . b . H and 'Siemens A G ' . With an attendance of almost 700 participants f r o m 27 countries, the Munich I C P R was the largest so far. In parallel sessions 251 papers were presented which were selected from 337 submitted papers. Furthermore, the program included 15 invited introductory papers for the scientific sessions, 4 panel discussions with experts from various countries and an exhibition of 50 chosen posters. The participants presenting papers came from 23 countries, the majority of them (about



75%) from the USA, the Federal Republic of Germany, Japan and France. A remarkable feature of the Munich conference was that special care was not just given to the scientific standard of the program, but that the application of pattern recognition was emphasized, too. For the first time the ICPR was accompanied by a technical exhibition - where fifteen companies and major research institutions were represented - and visits to research and development facilities where 9 institutions including the Technische Universit/it, local research facilities and industry could be visited. Tile conference program covered all fields of pattern recognition and its applications. The main interest was focused on computer-aided picture processing with all its aspects. Contributions from the field of artificial intelligence, particularly methods for the representation and usage of knowledge as well as search and control strategies, mark a new epoch for the topic of image understanding. Remarkable progress has been achieved also with regard to the scientific penetration o f this complex subject and the development o f standardized theories and strategies. Concerning practical applications, industrial and medical applications were predominant. Pattern recognition techniques offer advantage, where data from repetitive measurements at the present is evaluated and interpreted by persons; for example inspectorial and diagnostic work. Automatic recognition of workpieces and components in quality control, production and fault detection, as well as the automatic inspection and analysis of integrated circuits are typical areas o f applications of pattern recognition in the industrial environment. Methods for automatic character recognition, computer-aided analysis, document processing and text interpretation aim for clerical occupations, enhancing the efficiency of the workflow in management, office organization and administration. In the medical field the main objectives are automated detection and classification o f pathological cell structures (e.g. preventive cancer tests) as well as computer-aided evaluation of blood pressure curves, electrocardiograms and electroencophalograms. The conference provided a broad survey of the

field of pattern recognition; to the expert it offered the opportunity for profound and detailed discussions with colleagues from all over the world and for potential users it supplied access to comprehensive information on the future expectations. The conference proved clearly that the findings and methods of pattern recognition will have significant influence on the further development of information and communication technology.

Mini/Micro 82 Mini/Micro 82, a major computer conference and technical symposium which directly addressed the OEM marketplace, was held in Anaheim, California from September 14-16, 1982. The event was designed to bring manufacturers o f small computers, data communications, peripheral equipment and software together with an audience of highly qualified OEM design/systems engineers, assemblers, systems integrators, software specialists and corporate management. 25,000 attendees viewed the exhibition, at which over 200 companies displayed the latest in product and process innovation. The Professional Program, reviewed in the following report, featured 19 sessions, presented
