| Abstract | Objective—Multi-parameters are employed to design a device of lie detector, including Skin Temperature, electrocardiogram (ECG), Pressure of End-Tidal Carbon Dioxide (PETCO2), Oxygen Saturation and other physiological parameters. Methods: Skin Temperature is measured by temperature sensor, and it is used to monitor the difference during the lie detection procedure. Standard CM5 ECG lead, used to extract the signal of heart rate, re-extracted heart rate variability and other autonomic nervous system characterized by the parameters. Oxygen Saturation and PETCO2 detection were tested late changes of respiration and respiratory status. 300Hz sampling rate was used to capture the channel signal. Through the low-power microcontroller MSP430, the signal was sent into computer via USB communication. Result: After debugging and verifying, reliable physical parameters can be collected from multi-parameter detection system. It provided a set of physiological information monitoring for the hardware system. Discussion: Signal analysis software needed further design, at the same time adjust the acquisition parameters of front-end signal, and a reasonable configuration, all of them are lay the foundation of software system design. The result shows that the lie detector system based on physiological parameters is cheaper and more convenient than others. |

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.
