IIT Kharagpur has come up with a one-of-a-kind lifesaver technology that can be fitted in an ambulance to ensure remote monitoring of patient condition by the doctors even before they reach the hospital!
This technology named “AmbuSens” has been developed in the SWAN lab of the Department of Computer Science and Engineering (CSE) at IIT Kharagpur. AmbuSens is capable of wireless monitoring of various physiological parameters like ECG, heart-rate, temperature and blood-pressure. The system utilizes a unique hashing-based mechanism (patent filed) to preserve patient’s data confidentiality while simultaneously using the analytic and computing power of cloud computing. The web interface of the AmbuSens system provides an easy-to-use graphical interface for doctors and paramedics alike with data visualization tools such as real-time ECG graph rendering and can be accessed from internet-enabled laptops, tablets and smartphones.
“There is no such technology at present that can help doctors at remote at the hospital to continuously monitor the condition of the patient when the latter is on the move. This technology will be a boon for the referral patients who are transported from a hospital in remote area to a city hospital. Currently in such situations apart from family members, a medical technician companies a critical patient on an ambulance. But this technician has limited knowledge. Now with the doctors being able to monitor the patients on transit they can suggest medical interventions to the technician. This can be lifesaving,” said the principal investigator for developing this system Prof. Sudip Misra, Department of CSE, IIT Kharagpur.
The embedded system of AmbuSens includes both hardware and software. The system currently leverages wireless on-body sensors, cellular (3G/4G) and wireless technologies (Wi-Fi) and cloud computing to achieve seamless real-time monitoring and management of patient data. In future the system will work even with irregular Internet connection.
Here is how AmbuSens works – the referred hospital and the referee hospital as well as the ambulance will have laptops or tablets with internet connection. The patient will be fitted with wireless body sensors, which will help doctors of both referred and referee hospitals to continuously monitor the health condition of the ambulatory patients in real-time. Apart from monitoring critical patients referred from one hospital to the other an ambulance fitted with AmbuSens can be life saving for accident victims or cardiac patients who need to be transported to the hospital immediately.
This technology is several steps ahead of telemedicine where the doctor can see the patients but do not have wireless real time monitoring of their health condition. “We conducted successful field trials of the developed system at All India institute of Medical Sciences (AIIMS), Bhubaneswar and BC Roy technological hospital (BCRTH), IIT Kharagpur. The trials were conducted on various patients (both male and female) admitted in intensive care unit (ICU), cardiac unit and patients coming for normal health check-up (OPD). Patients within age group of 10-70 years were considered for the trials. The duration of trial for each patient was around 20-30 minutes,” said Prof. Misra.
The researchers are currently working on further upgrading AmbuSens so that in future the technology can ensure advance prediction of a likely to have emergency (like cardiac arrest) of the patient in the immediate future. This will enable patients to get care before onset of emergency, potentially saving lives. Several sensors are also being developed to help monitor many more health parameters of the patients on the move.
A state government from Northern part of India has already shown interest in this technology to help monitoring patient conditions in difficult terrains where the number of hospitals are limited.
The principal investigator for the development of this system was Prof. Sudip Misra, Department of CSE, IIT Kharagpur. The co-investigators were Dr. I. Banerjee (BCRT Hospital, IIT Kharagpur) and Dr. Saurav Sarkar (AIIMS Bhubaneswar). The project staffs who worked on it are Niloy Saha, Subhadeep Sarkar, and Pradyumna Kumar Bishoyi.
The salient features of the AmbuSens system are as follows:
1. Telemedicine and Remote Healthcare: Utilizes wireless on-body sensors for improved mobility and user-convenience. Enables easy trend tracking and remote monitoring by specialized medical personnel without having to be physically present.
2. Improved Emergency Response Time: Instant remote monitoring and feedback by the skilled medical professionals to paramedics for improved emergency diagnosis and treatment.
3. Real Time Patient Status Monitoring: Continuous real-time monitoring of the patient from anywhere with internet connectivity provides up-to-date feedback about the status of the patient, and enables improved collaboration among hospitals.
4. Cloud-based Digitized Medical History: Consistent cloud-based digital record-keeping system, which is fully privacy-aware and is accessible by all authenticated users across various healthcare facilities.
Future directions for the AmbuSens system
1. Warning before heart attack occurs will be possible in the future, based on gathered data.
2. The system will work even with irregular Internet connection.
3. Various others sensors including but not limited to Pulse Oximeter (SpO2) will be added.
4. There will be options to add scans of existing medical records (e.g. X-rays) to the system to those doctors can access patients' data from one single place.

Researchers at IIT Kharagpur have achieved a breakthrough that will change the way biofuel is manufactured all over the globe by making the process cheaper, quicker and above all pollution free.
The ‘soil-to-soil’ manufacturing technology developed at the P. K. Sinha Centre for bioenergy at IIT Kharagpur is in the process of being patented. Explaining how the technology would work Dr. Rintu Banerjee, Professor of Department of Agricultural and Food Engineering, Ex-Chair professor, MNRE, P. K. Sinha Center for bioenergy said, “2g bioethanol can be produced from various naturally available lignocellulosic components. But to do so it needs to be treated chemically and in some cases physic-chemically . Because of chemical treatment the process contributes to polluting the environment. We have replaced this chemical treatment with enzymes which degrade the lignin specifically there by making the manufacturing process pollution free.”
“Also unlike the chemical treatment here the waste product is pollution free and hence utilizing the residual biomass to organic fertilizeris possible. The solid waste recovered after bioethanol production is subjected to produce methane gas thereafter the fermented biomass was enriched with cyanobacteria to convert the residue into fertilizer. It is soil-to-soil technology, an integrated process where we are using natural resources to extract gaseous and liquid biofuel and then converting the wastes into bio fertilizer. It is an unique integrated approach which we have developed in our lab,” she added.
The ‘National Policy on bio-fuel’ targeted20% blending of biofuel with petrol by 2017. But the target so far remains unachieved. With the government expecting bio fuel business in India to touch ₹50,000 crore by 2022 this new green technology with lesser manufacturing cost and time can become a game changer. “The technique that we are suggesting will ensure relatively quicker production of bio fuel and ensuing that the process is completely green. There by not creating any secondary pollution. This, we feel can change the future of bio fuel manufacturing in India and make it more cost effective,” said Prof. Banerjee.
Presently this project is funded by the Ministry of Petroleum and Natural Gas, Department of Science and Technology and the Ministry of Human Resource Development. Here they are taking care of another government mandate – not to use consumable food crops for the purpose while manufacturing bio fuel. Hence IIT-KGP is producing bioethanol, biobutanol, biodiesel, biohydrogen and bio-methane in its pilot plant using various non-edible lignocellulosics which would have otherwise been wasted.
The green leafy part of corn and sugarcane plants, the waste part of paddy straw, bushy bamboo, sorghum, banana plant, pineapple and cotton plants, kans grass (kassh phool), castor plant and even non edible weeds that grow in dry and waste land and a mix of all has been used by IIT-KGP to produce bio fuel. Recently the center has also succeeded in extracting bio diesel from used cooking oil, which was otherwise thrown away by the restaurants. To make the process zero wastes, glycerol has been used for growing oleaginous microbes and thus the lipid recovered can be used as biodiesel. This is also a green technology.
“Through these technologies we have successfully produced zero pollution bio fuel from 550 kg of biomass in our pilot plant. Unlike other bio fuel manufacturing process it requires very less water as well as the production process is quicker, which means the manufactures will not require huge reactors. The by-product when converted into organic fertilizer will ensure more income for the manufacture. The technology is ready for industry use,” said Prof. Banerjee
The research group under the leadership of Prof. Sudipta Mukhopadhyay at the Dept. of Electronics and Electrical Communication has received the FICCI Research & Development Award 2017 for their innovation "Real Time Fog Removal from Videos & Real Time Rain Removal from Videos".
The innovation ideas were submitted by Mr. R. Hariharan and Mr. Manish Kumar Sharma. This work is the accumulation of contributions of research and development by Dr. Abhishek Kumar Tripathi, Mr. Nishant Gaurav, Ms. Bhamidipati Sridevi, Ms. Ashwini R. Patil and Mr. Leuva Hardik P. in addition to R.Hariharan & Manish K Sharma.
The team developed algorithms for removing fog and rain from videos in real time. The fog algorithm estimates the distance of the objects from the camera in the form of the depth map. The depth map is further refined using anisotropic diffusion to identify clear boundaries of the object. Based on the refined depth the image is restored back to give cleaned images. This operation is performed on every frame of the video to generate a defogged video stream.
Probabilistic model based temporal and spatio-temporal rain removal algorithms are developed which are both effective in removing rain from rain affected videos and are real-time in nature. It is based on the difference in the time evolution properties of that rain and non-rain pixels.
Prof. Manish A. Mamtani, Professor, Department of Geology & Geophysics has been appointed as Vice-Chair of the International Union of Geological Sciences (IUGS) Commission on Tectonics & Structural Geology (TecTask).
