Abstract | In order to deal with the shortcomings of a photoelectric mode cardiotachometer, such as wasting energy and slowly refreshing results, this study mainly focuses on a real-time displayed, portable, low-cost, and energy-saving cardiotachometer. The design is based on the Mbed, which is the core microprocessor, controlled and dispatched by the built-in function. Before filtering and amplifying the electronic signal, the pulse signal is collected by the photoelectronic sensor at the beginning of the whole process of the cardiotachometer. The energy-saving function can be achieved through audio p-type metal oxide semiconductor to switch on and off the light-emitting diode (LED) which is in the sensor. Eventually, the real-time ratio of the heartbeats and the waveforms can be displayed on the two 8 × 8 LED modules at the same time with overall energy-saving of about 50%. This design can be applied in many fields focusing on long battery life and portable, especially as a part of a wearable device. |

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.
