International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / The Remote Unit (RU) for a decentralised on-board base-band telemetry system is designed for use in launch vehicle missions of the Indian Space Research Organisation (ISRO). This new design is a highly improved and miniaturised version of an earlier design. The major design highlights are as follows. Usage of CMOS Field Programmable Gate Array (FPGA) technology in place of LS TTL devices, the ability to acquire various types of data like high level single ended or differential analog, bi-level events and two channels of high speed asynchronous serial data from On-Board Computers (OBCs), usage of HMC technology for the reduction of discrete parts etc. The entire system is realised on a single 6 layer MLB and is packaged on a stackable modular frame. This paper discusses the design approach, tools used, simulations carried out, implementation details and the results of detailed qualification tests done on the realised qualification model.

The purpose of this reasearch was to develop a respiratory monitoring system using a reflective object sensor based belt to measure the thoracic expansion of a neonatal for future application at the medical center of the Universidad Evangelica Boliviana (UEB). This medical center, being founded by the UEB University, is dedicated to help and serve the poor and currently has no respiratory monitoring system. The methodology used was first to build and test the respiratory sensor belt and test the relationship between the blet expansion and the voltage generated. The, to incorporate the respiratory sensor belt in a system that would allow individual testing as well as group testing in a wireless network. The system was simulated using an expandable plastic container that was expanded and extracted periodically, registering the results in a MATLAB software. The system gave successful results and generated the frequency results of each cycle, average frequency and deviation frequency. The system demonstrated to be reliable and to have repeatable results.
