Abstract | Fall is a major problem for the elderly persons and patients suffering from neuromuscular disorders. A body-worn fall detector can greatly help in providing timely assistance by alerting the emergency services and relatives in case of such an occurrence. A wearable inertial sensing device is developed for fall detection and motion tracking. It consists of an integrated sensor with tri-axial accelerometer and tri-axial gyroscope for sensing linear acceleration and angular velocity, a microcontroller for data acquisition and processing, nonvolatile memory for recording the sensed data, and Bluetooth for wireless connectivity. A fall detection algorithm applying multiple decompositions and thresholding on the acceleration data is implemented for real-time processing using sampling frequency of 100 Hz. The sensed data can be continuously recorded for approximately 10 hours at a sampling frequency of 20 Hz and therefore the device can also be used for actigraphy for diagnosis of sleep disorders. A number of such devices worn on the different parts of the body and wirelessly connected to a central device can be used for continuous tracking of the posture and movement and can serve as an aid for assisted living. |

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.
