Device helps paralysed ‘Ra.One’ animator Charu type

Hindustan Times (June 18, Mumbai Ed) has carried news about Prabhat Ranjan’s work in trying to enable Charu Khandal, Ra.One movie animator, who won Filmfare award for Best Special Effects movie. However the party to celebrate the award took a tragic turn, when her auto was hit by a drunk driver at end of party. She is now paralyzed neck down with no hands/leg movements. On June 8, she was given a Brain-Computer Interface to let her type using her head movement and brain waves.

She is among the four users in India, who have been able to benefit from this system. First user was Mr K Suresh from Coimbatore, about 3 months back. He is using it effectively about 4 hours a day since he cannot sit on wheel chair for more than 2 hours at a stretch.

Harmony India : Light of Life

Suresh Karat, who had a brilliant career after receiving
an MBA from IIM-Ahmedabad, suffered a brainstem
stroke at the very young age of 32, in 1999. This left
him severely disabled; he became a quadriplegic (no limb
movements) with no speech. He could read and hear but
could not communicate. He could communicate with his
wife Jaya only through eye blinks.

DA-IICT Prof ‘enables’ quadriplegic IIM-A Grad

“Imagine spending 13 long years unable to move a finger, dependent on your family for all your daily needs. That was the life of 1993 batch alumnus of Indian Institute of Management – Ahmedabad (IIMA) Suresh Karat. But, not anymore. Suresh is now enjoying a new sense of liberation.”

Social innovations the mantra of Science says Professor Prabhat Ranjan

The best thing about Science and Science researchers is to use their knowledge for the good of the society. Prof. Prabhat Ranjan has been working at the Dhirubhai Ambani Institute of Information and Communication Technology, Gandhinagar since 10 years. Currently, he is working to apply Embedded Systems and Sensor Networks to Planetary Exploration (Moon Mission), Wildlife Tracking, Nuclear Fusion, Healthcare and Agriculture. An IIT Kharagpur grad and a Phd from California, he talks to Gyancentral’s Mansi Sheth about innovation and building devices for the disabled and others.

Learning disability, Mantra and Brainwaves!

I have been trying to understand brainwaves and its relationship to learning disability in children. Scientific research shows the parameter Beta1/Theta waves being a key criteria. To improve this “Brain Entrainment” or neurofeedback can be used. These typically need auditory stimulation of brain. Our Yoga and mediation also seem to work on brainwaves. I was wondering if our traditional “Mantra” also has something to do with this. I found this on net – “In his research conducted a few years ago, Dr Herbert Benson observed that chanting of specific mantras produced a “relaxation” response, causing reduction of heart beat, brain waves and respiration.”

In one more paper,, they claim “Practitioners understand ‘‘meditation,’’ or mental training, to be a process of familiarization with one’s own mental life leading to long-lasting changes in cognition and emotion. Little is known about this process and its impact on the brain. Here we find that long-term Buddhist practitioners self-induce sustained electroencephalographic high-amplitude gamma-band oscillations and phase-synchrony during meditation. These electroencephalogram patterns differ from those of controls, in particular over lateral frontoparietal electrodes. In addition, the ratio of gamma-band activity (25–42 Hz) to slow oscillatory activity (4–13 Hz) is initially higher in the resting baseline before meditation for the practitioners than the controls over medial frontoparietal electrodes. This difference increases sharply during meditation over most of the scalp electrodes and remains higher than the initial baseline in the post meditation baseline. These data suggest that mental training involves temporal integrative mechanisms and may induce short term and long-term neural changes.”

West has started using “mantra” for their benefit as seen in this video :Gayatri Mantra being used in West

So now need to find if learning disability can be improved through our traditional knowledge!

My First Open Source Software at Lawrence Berkeley Lab(1986)

I was writing my PhD thesis in Berkeley in the 1985-86 period. When Mac was released in 1984 and they came for a demo to Lawrence Berkeley Laboratory (LBL), many scientists loved the idea of Mac and they placed orders then and there. I offered to set up the first Mac that arrived in my group. Once I did that, I had to do that for each of the subsequent Macs that arrived in the group.

Android bluetooth link to Tata Indigo Manza Car

About one year back, I had purchased a TATA Indigo Manza Elan car. This has a feature to allow bluetooth based phone to connect to sound system in the car. This makes one handle hands-free phone call, while driving. I have a LG P500 Optimus Android based phone. Initially when I linked Bluetooth, it worked after I learned to connect the device. Some time back I upgraded my Android version to 2.3 from 2.2. After this I noticed that bluetooth link would connect but calls would not be handled properly. I could not hear incoming call etc.
I have been now able to solve this problem by adding an app named “Bluetooth Manager”, available from https://play.google.com/store/apps/details?id=com.mdsoftware.bluetoothpowermanager&hl=en. Now if I connect the car bluetooth system through this application, my phone call is handled properly. I do not know why it was not working otherwise but shared this here in case some one else has a similar problem.
