| Abstract | Prevention of falling during walking or transfer is important for maintaining quality of life in the elderly. Analysis of falls among the elderly is useful not only for preventing falls, but also for detecting disease in its early stage. The aim of this study is to develop an ambulatory monitor that records falling time. The system consists of a fall sensor, a sensor driver circuit, a microprocessor and a real-time clock. A photo-interrupter is used as the fall sensor because it does not require an electrical switch. The photo-interrupter outputs a trigger signal when the subject is falling and the microprocessor records the falling time. To minimize the power consumption, the photo-interrupter is driven with pulse current, and the microprocessor that records falling time is only operated when the subject is falling. The system works continuously for one week. In this preliminary study, the system was tested for normal adults and hemiplegic patients, and operated without any trouble. Using this ambulatory system, we can obtain data about falling over a long period. |

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.
