| Abstract | This report describes the performance of using reflective photo-coupler to locate an object. In this paper, a method of range-finding based on infrared (IR) techniques is proposed. We successfully eliminate the interference of the environment by means of circuit techniques; and let the low-cost IR sensor accurately detect the position of a target. Additionally, we investigate the differences in the detectable range and resolution between using a discrete type and using a modular type. The experimental design was of using a movable work platform driven by a stepping motor, and using a data-acquisition (DAQ) interface to obtain the measured data via the Laboratory Virtual Instrument Engineering Workbench (LabVIEW) software on a PC. The movable mechanism which sets up the tested sensor can get a resolution of 0.1 mm in displacement. Experimental results show that the modular type is suitable for measuring in the near distance but the discrete type is used in the further distance. |

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.
