| Abstract | The paper proposes a control method of an index finger prosthesis by using two electromyographic signals measured on skin surfaces of two muscles (flexor digitorum superficialis and the extensor indicis) in a lower arm. We assume that the mass of the human index finger is sufficiently small for its dynamic effect to be neglected and the initial burst part of electromyographic signal generated by human intention precedes the onset of actual displacement of the index finger. In order to make the control input for the index finger prosthesis, the root mean squaring operation is applied firstly to the measured electromyographic signal, the thresholding operation is secondly utilized to extract the initial burst part, the synergistic signal is thirdly constructed by using the difference between two processed electromyographic signals, and then the desired displacement is derived from the scaled synergistic signal and numerical integration. Physical limits of the utilized actuator such as displacement and speed limits are considered for practical control use. Finally we show the effectiveness of the proposed control method through experimental result. |

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.
