| Abstract | The design of cardiac pulse generators has evolved from an artificial pacemaker single therapy device to a multifunctional therapeutic device known as an implantable cardioverter defibrillator and pacemaker. Composed of complex digital circuitry and discrete components, these devices may exhibit susceptibility to EMI. Despite shielding the internal mechanism of pacemakers and ICDs with titanium casing and using improved noise filtering techniques, new sources of EMI continue to pose challenges in EMC design of these devices. There have been previous reports of interference from RF sources such as radar transmitters, hand-held radios, and anti-theft devices. More recently, with the proliferation of wireless communication, reports of interference by digital cellular telephones have also surfaced. FDA/CDRH initiated an examination of the potential for cellular telephones to interfere with implanted pacemakers in 1995. Results of these evaluations led CDRH engineers to investigate the potential EMI effects of these telephones to ICD function. The investigation involved ICDs from six manufacturers versus four types of digital cellular telephones. An RF powered dipole antenna was also used to evaluate it as an alternative RF source for EMI testing. |

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.
