India has some 40 to 80 million persons with various kinds of lower limb disabilities. Wheelchairs are a very common mobility assistance system for people with lower limb disability. However wheelchairs cannot serve people with upper both upper and lower limb disability.

It  is suited for persons with both upper and lower limb disability. It is a battery driven wheelchair, which can be operated through joy stick or using tongue and head movements depending upon the kind of disability the person has. The chair sports sensors attached on the seat at the neck position and these can be operated by the movement of the neck to maneuver the wheelchair. Similarly the tongue may also be used to provide inputs to the wheelchair’s mechatronical system through sensors. It can also be easily elevated to a convenient height. This wheelchair facilitates easy movement for people with spinal injuries, as they can navigate it using their tongue.

The project team received the Gandhian Social innovations award at Gandhian Young Technology Awards 2012

The project has designed a novel drug formulation that inhibits breast cancer causing agent using carbonitrile group.

Inhibition of aromatase, a cytochrome P-450 enzyme responsible for biosynthesis of estrogens, is an effective approach for the prevention and treatment of estrogen-dependent breast cancer. Carbonitrile containing compound shows enhancement in aromatase inhibiting activity. The present work aims to introduce carbinitrile group in ring-D and to observe its impact on the aromatase inhibiting activity of the molecule. A novel A- and D-ring substituted steroid 16β-cyano-17β-hydroxy-4-phenylthia-4-androsten-3-one (7) has been synthesized and evaluated for its potential as aromatase inhibitor using human placental microsomal preparation as the enzyme source  and [1β-3H]androstenedione as substrate.

The project comprises of a new technique for providing tsunami forecasting. Accurate forecasting of Tsunami can be very vital in issuing warnings and evacuating the people from regions with the possibility of being hit by tsunami.

The cost of this tsunami warning system may be a hundred times cheaper than the existing systems due to the very low cost of obtaining TEC data from satellite pratham.

The project uses a novel technique for ionospheric tomography using the TEC data. The TEC data for this system is obtained from Pratham, a satellite developed by IIT Bombay. The TEC data is being generated using ten ground stations in India and one in France. The algorithm reconstructs the distribution of electron density across various layers of the ionosphere with more than 85% accuracy. This allows forecasting tsunami with a good deal of accuracy.

The project team received appreciation award underthe category ‘Technological Edge’ at the Gandhian Young Technology Award.

It uses an embedded system to classify tiles in different grades using digital image processing and measure the thickness of tiles using ultrasonic waves. The ceramic tile industry is almost completely automated with the exception of the last step of visual inspection, which is undertaken for the classification of tiles into different grades.  In this system designed by the innovators, images of tiles are captured, digitized and an algorithm used to compare it against a standard tile image and accordingly the tiles are classified.

To measure the thickness of a tile, ultrasonic waves involving pulse echo method are used. The measurement unit uses a continuous signal in the transmission frequency range of ultrasonic transducers. The team designed the systems for a Tile manufacturer based in Morbi, Gujarat. The students had identified this problem as ‘industry defined problem’ while on an industrial shodhyatra at the local unit of tile manufacturer.  The automation of the tile grade classification may reduce the time and improve the reliability of tile grade classification.

Wheelchairs are extensively used by disabled people to enhance their personal mobility. One of the basic problems of user on manual wheelchair is overcoming architectural barriers like kerbs,stairs etc. on its way.

Vardaan facilitates climbing up and down the stairs by using an innovative ‘Y’ shaped wheel that provides better grip and optimum braking along with a ratchet and a braking system. The ‘Y’ shaped wheel has been designed to mimic the human gait while climbing up. For climbing up the user pulls and pushes the lever ratchet attached on the axle of the Y shaped wheel. The design makes use of the fact that people with lower limb disability have high upper body strength and therefore pulling/pushing the ratchet lever can be conveniently operated by them. While during the climbing down the user can use brakes to control the motion of the wheelchair as the ‘Y’ shaped wheel rolls down the steps.

The braking system along with the ‘Y’ shaped wheel is likely to make the wheelchair a safe solution for climbing stairs for the user. The initial prototype has been tested under various circumstances like step sizes of stairs, people with different weight (58 kg-89kg) and it has shown satisfactory results. The wheelchair can navigate stairs with 350-230 mm width and step heights from 110-185 mm. As per National Building Code Specifications for step sizes of staircase of public building VARDAAN can climb all the public stairs.

The project received Gandhian Young Technology Awards in April, 2012.

This prototype combines a water heater along with refrigerator. This modified Domestic refrigerator has two interesting novel functions. The waste heat of compressor is used to heat water, through a heat exchanger and in the process of removing heat, the life of compressor is extended and its efficiency goes up. Thus the power consumption also goes down because compressor has to work less.

The lukewarm water thus generated can be used cleaning kitchen utensils, washing clothes, bathing etc. Through this modified design daily 100 liters of lukewarm hot water can be produced while the cooling capacity of the refrigerator is increased by about 20 per cent . This may also reduce the consumption of electricity.

The project received appreciation under the Gandhian young Technology- ‘More from less’ category.

Prof. Anil Gupta had the following comment on the project technology in his DNA column:

“Every fridge manufacturer must be obliged to attach a heat harnesser to the compressor so that energy consumption in the fridge goes down and user can harness extra heat for casserole or heating water. In fact, if pulses are kept in hot water for a while, they cook faster and save further energy. Some of the vegetables need not be cooked at all and they may become palatable merely by keeping in hot water, saving all the nutrients as well.”

Project Hope is an Image, Speech Recognition and Speech Synthesis system. It aims to aid people suffering from hearing and orating /vocal impairments.

Often people suffering from such disability have normal vision and therefore they are able to communicate through sign or gestures. This system through a webcam converts signs into text. The other person who may not know sign language can read this text. It can also be heard through text to speech. Further, when the other person speaks, the system will convert into a text which the deaf and dumb person can read,
Presently the system supports English. The device consists of a wearable camera along with speaker. The vocally disabled person can keep his hand in front of the camera and make gestures using sign language. The camera may capture the gestures and the onboard electronic system will identify and convert the gestures into text. The Onboard voice synthesizer will convert the text into voice. For the hearing disabled the onboard system may record the external voice and convert the same into text that will be displayed for the user.

The device may be lightweight and therefore the user may wear the system on his body. The innovators are also in process of developing a Gestural API, so those using this platform can directly proceed to make use of the platform’s functionality. The team needs support to make the functionalities more smooth, develop viable prototypes and take it to market.

An automobile AC consumes about one-tenth of the total fuel. This is a significant cost for the vehicle owners such as truck drivers who travel round the clock running. The innovation by Harish Tiwari addresses this challenge by designing an AC that may be able to run itself by using waste heat from the automobile exhaust. It may therefore make the running of an automobile more economical. It achieves this by using an adsorption refrigeration system powered by exhaust heat with only two control valves. A prototype of 1 kW cooling capacity has been designed and developed in the laboratory. The adsorbers use an innovative double pipe heat exchanger to enhance heat transfer and reduce the heating and cooling time. The system dimensions have been obtained and found to be suitable for Automobile and the system can operate in mobile applications. The overall weight of the system for a cooling capacity of 1 kW is around 30 kg. The heating time required to achieve the cooling effect is around 10 minutes. The number of valves is just two which gives reliability to the system and reduces the likelihood of leakage. The project requires support in fabricating a full-scale prototype. The project received Appreciation under the Gandhian young technology awards ‘More from less’ category from Dr. Mashelkar.

Continuous electricity supply is still not available in large parts of the country. Still the people in these regions require refrigeration for a variety of socially relevant purposes such as cold storage or storing medical supplies. This project has the novelty of using LPG instead of electricity for refrigeration. This solution is convenient for refrigeration in regions without proper electricity.
It works on the principle that during the conversion of LPG into gaseous form, expansion of LPG takes place. Due to this expansion there is a pressure drop and increase in volume of LPG that results in the drop of temperature and a cooling effect. This cooling effect can be used for refrigeration purposes.
The technology can provide refrigeration for socially relevant needs in areas where continuous electricity supply is absent. It can also replace refrigerators currently using CFCs and HFCs, which are causing global warming.
The Gandhian awards received prototypes from two teams based on this concept.

Team 1:
The team from Laljibhai Chaturbhai Institute of Technology made a prototype in which the evaporator temperature reached -5 ºC at an ambient temperature of 12 ºC.
