The work demonstrates a simple, handheld, micro-heater integrated MOX-based gas sensor interface system that includes digital set point, a precise closed loop temperature controller and a wide range resistance readout circuit. The implementation of the proposed system constitutes two circuits. The temperature control loop circuit is able to set the platinum microheater temperature over a range [...]

An embedded system with a light-emitting diode (LED) and a phototransistor for soil nutrient measurement was developed (Fig. 1). The light from sample or reference cell was detected by a phototransistor. The detected signal was fed to the Atmega1284P microcontroller through signal conditioning circuit. The analog signal from phototransistor was converted into digital signal. The absorbance [...]

The project was taken up under India and Slovenia scientific and technical cooperation. The objective of the project was to unobtrusively monitor daily living activities of elderly and subsequently determine their wellness. It would be achieved by measuring the effects of human vital signs when a person approaches non-invasive sensors, including video camera and with the [...]

3D vision System Development for Automation of Surgical Process A technology is being developed for a 3D endoscope for Minimum Invasive Surgical System to replace the conventional one. A 3D endoscope enables the surgeon with depth perception and stereo vision. It will have a light source and a video camera at one end. When inserted into [...]

The objective of the project was to continuously assess the dynamic parameters of the structure with an optical camera using intelligent algorithms. A technology is being developed for continuously assessing the dynamic parameters of the civil structure under study using real-time vision based algorithms. A non-invasive approach would be used for continuous health monitoring of bridges. [...]

The objective of the programme was the extraction and Damage/Defects identification in the civil structures and their assessment using Image Processing and Artificial Intelligence. A technology is being developed for identifying the size, depth, type and location of the damage in the civil structure for their health monitoring. It is a non-invasive approach, based Fig. 1: [...]

During the year various characterisations on Scanning Electron Microscope (SEM) and micromanufacturing on femtosecond laser machine were done. The samples processed in the lab for micro manufacturing and characterization have a wide variety of material namely Copper, Tungsten, Ceramic Substrate, Alumina, photonic material composite deposited on a wafer , sapphire and Silicon. The requirements of micro [...]

A second-stage channel temperature controller system for attaining and maintaining the temperature of the fluidised bed Gasifier was developed and installed. The input temperature at the Gasifier was around 300 °C and the desired temperature was from 700 to 800 °C. The system was installed at CSIR-CMERI, Durgapur, and the field trials would be done after [...]

The system consists of four components: PV cell, drive (CSIR-CEERI), motor and pump. The built-in power point tracking functionality enables the pump to run at a maximum power using solar power. It is independent of the grid and produces no pollution or noise. Solar pumping solutions are becoming increasingly popular among Indian farmers irrigation, forestry, fish [...]

The commercial Blood Pressure (BP) monitoring devices do not provide continuous monitoring of arterial blood pressure. The project aims to develop a wearable device suitable for continuously and non-invasively measuring the blood pressure (see figure below). Further, the device will be portable, easy to use and will be customised for a large scale deployment in low [...]
