| Abstract | Several device-specific, radiated electromagnetic interference test methods have been developed for particular combinations of medical devices and nearby sources of radio frequency interference (RFI). These tests are useful for supplementing the prevailing, generic standardized medical device RFI immunity test methods. Generic tests such as those specified IEC 601-1-2 and related standards underestimate the degree of RFI problems that can be encountered in the close proximity of handheld transmitters and cellular telephones. This occurs because the generic standards admittedly do not relate their test conditions to extreme exposure situations. Device-specific test methods have been developed by several organizations to evaluate the susceptibility to nearby transmitters of implantable cardiac pacemakers and defibrillators, as well as hearing aids. The U.S. Food and Drug Administration (FDA) developed and tested a "universal", simulated near-field RF source for this kind of test. It consists of a standard dipole antenna connected to an amplitude-modulated RF generator that can simulate a wide range of worst-case RF carrier frequencies and modulations. Another new device-specific test is the draft ASC 63 standardized test method for "ad-hoc" RFI testing. It is proposed to be used to evaluate the RFI susceptibility of a wide variety of specific medical devices. Individual RF sources will be used, such as handheld transmitters, placed one meter from the medical device under test in the actual clinical setting. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
