The visually impaired have to face many challenges in their daily life. The problem gets worse when there is an obstacle in front of them. They feel difficulties Blind stick is an innovative stick designed for visually disabled people for improved navigation. To overcome all these problems of blind people, we are developing a walking cane with OPCFD system by using simple available technologies. OPCFD system which means it can detect obstacles, pits, ceilings and fire .This walking stick for blind people has multiple sensors, with the help of which it has been possible to enhance more features to the walking stick. The features are to detect the obstacle for collision avoidance, it detects the object in directions up, down and front. The other sensor placed near bottom tip of the walking cane to find the pits on the ground. Temperature sensor to detect temperature of the surroundings and wheel with generator connected to end of the walking cane while walking due to the rotation of the wheel it produce some current.In this project, sensors play a key role to detect the objects in all directions and thus help blind people to be independent.

In this experimental based research work, the performance of Thermal Energy Storage System (TESS) during charging (melting) and discharging (solidification) processes were studied under varying conditions. The results from the CFD simulations for these conditions were published earlier. Here, the experimental results had been discussed. Paraffin wax concentration was varied to form the TESS. Al2O3 was included as nano-material with a varying concentration – 0% (Base Model), 1% (Variant-1), 2% (Variant-2) and 3% (Variant-3). It was observed that the Variant-1 had provided better performance for Configuration A under the heat load of 125 W and 175 W in the melting process. During the solidification process for the Configuration B, Base Model had better performance than the variants with nano-fluids. Results from CFD simulations as well as experimental procedure were in good agreement for this research work.

The wearables have long been used in the healthcare sector, for example in hearing aids, in detecting health disorders such as sleep apnea and in detecting the blood pressure etc. As smartphones have become one of the necessary gadgets of our daily life we can use its potential to develop an application with the help of these devices to make the system easily wearable and mobile. This project describes the Android Application Which will continuously monitor the pulse rate of the user & collect the data. This data will be sent to the nearest people in the form of the text message as well as alarm generation just by pressing the smartphone screen for few seconds. This message will contain the pulse rate details and also changes in the location of handicapped people so that further emergency actions will be taken. The K-Nearest Neighbors algorithm will be used to find out the nearest people of the user. This system will be developed considering the handicapped people.
