Slow Potentials and Microprocessor Applications


Book Description

Investigators and clinicians researching and applying electrophysiologic phenomena of the eye, met for the XXth Symposium of the International Society for Clinical Electrophysiology of Vision in Iowa City, Iowa, under the auspices of the University of Iowa and supported by the Department of Ophthalmology, headed by Professor Frederick C. Blodi. Two main topics were discussed: I) Electro-oculography and other slow potentials: the phenomenon, origin, analysis, and clinical diagnosis, and 2) Microprocessor applications for computer-assisted recording and analysis of electro visual phenomena. Unusual and challenging diagnostic problems were presented during one evening session. The interest and lively audience participation indicated a need for such an unrehearsed debate. Drs. H.W. Skalka, H. Nakano, H.S. Thompson, A.J. Packer, J.A. Parker, H.E. Kolder, V.M. Hermsen, M.L. Wolf, and Mr. A.1. Mallinson presented case reports and are herewith recognized for their contribution. No documentation is contained in the Proceedings. Several papers were read outside the main topics. Some material appears only as abstract. The highlight of the scientific program proved to be an improvised session on basic mechanisms of slow potentials from the eye. Dr. R.H. Steinberg and his collaborators, together with Dr. G. Niemeyer initiated this part of the program. It was enthusiastically received, provided an informal atmosphere, stimulated a lively discussion and exchanged pro found information. A novel feature of this volume is the addition of a cumulative index covering the Proceedings from the last ten ISCERG-ISCEV Symposia. Dr.

Development of Electronic Aids for the Visually Impaired


Book Description

This book is based on the papers presented at the Workshop on "Rehabilitation of the Visually Impaired" held in Flo rence at the Institute for the Research on Electromagnetic Waves of the Italian Research Council on April 4-6, 1984. The Workshop, sponsored by the Committee for Medical and Public Health Research of the Commission of the European Communities, was meant to exchange ideas about the need, importance and feasibility of a European cooperation in the field of visual impairment and to identify promising research areas, where current national activities could take advantage of such a collaboration in order to increase their efficiency. In particular, it dealt with the develop ment and use of technical aids (mainly based on computers and signal processing techniques) and with the elaboration, evaluation and standardization of new methods and tests. The attendance was multidisciplinary, including researchers from the fields of technology, medicine and psychology and representatives from organizations involved in the rehabi litation of the visually impaired. Five technical sessions were organized, dealing with the following topics: automatic production of Braille and systems for paperless Braille, aids for reading and for the interaction with coded informa tion sources, low vision aids, transduction of visual infor mation into a tactile representation, mobility aids. Three different application sectors were mainly considered: education and culture, vocational training, mobility. A final session was devoted to a discussion in working groups. The results are briefly outlined in the following concise report of the Workshop.







EMC at Component and PCB Level


Book Description

This book provides the knowledge and good design practice for the design or test engineer to take the necessary measures to improve EMC performance and therefore the chance of achieving compliance, early on in the design process. There are many advantages for both the component supplier and consumer, of looking at EMC at component and PCB level. For the suppliers, not only will their products have the competitive edge because they have known EMC performance, but they will be prepared should EMC compliance become mandatory in the future. For consumers it is a distinct advantage to know how a component will behave within a system with regard to EMC.Shows how to achieve EMC compliance early on in the design processProvides the knowledge to trace system EMC performance problemsFollows best design practices
