| Abstract | So far, there has been no seismograph dedicated for metal mineral exploring in the world. A type of non-cable telemetry seismograph and its network composed of hundreds of Seismic Data Collecting Stations(SDCS) are presented for deep metal ore exploring. Without cable, there are several key problems need to be resolved: the synchronization in network, mass data storage, performance monitoring in field and power consumption management. The technology of Global Positioning System(GPS) timing in conjunction with a high precise Real Time Clock(RTC) is employed to achieve network synchronization with accuracy of ±3.2μs. Instead of data transmission on cables during data acquisiton, a Compact Flash(CF) card of 8G bytes is adopted in embedded linux system based on Advanced RISC Machine(ARM) to store seismic acquisition data. A built-in self testing module is constructed to monitor the health status of each measuring unit. At last, the working voltage and frequency of each SDCS are brought down on premise of normal work and Dynamic Power Management(DPM) is used to reduce the average power dissipation to make the whole system feasible. |

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.
