Drones delivering goods ordered online and being used to photograph exotic locations which are inaccessible to humans are already well known. How about a drone-based fire extinguisher that can reach any spot without the hassles faced by fire tenders or firemen?A Bengaluru-based aerospace firm — Poeir Jets — is developing heavy-lift hybrid drones for the purpose, which has already attracted the attention of a Spanish firm, Drone Hopper, for mass production.

Speaking to TNIE, Devathathan Mookiaha, director of Poeir Jets, said that the ‘Urban Firefighting Hopper’ is designed to restrain fires, especially in high-rise buildings. “The drone uses six micro-jet engines — developed by Poeir — to carry either extinguishing foam or water to douse flames,” he said.
The hopper is among the four heavy-lift drones being developed by the firm. “For the ‘Firefighting Hopper’, one-third of the research grant is being provided by the Department of Science and Technology,” he said.

Mookiaha and the firm’s co-founder Sridhar Balaram have been developing heavy-lift drones for the past three years and were the first company in the country to develop micro-jets. These micro-jets are being used for drones developed by the company.

Poeir Jets has also launched three heavy-lift drones during the ongoing 12th Aero India. While its Turbo Shaft MTS 30 will be able to carry weights of up to 200 kg when fully developed, Hybrid Drone DJE 30 has a capacity to carry weights of up to 75 kg for more than two hours.

It is currently being used on rare texts in Udupi’s Ashta Mutts

Thousands of manuscripts scattered across India — many lying in neglect or threatened by the exposure to vagaries of nature — are facing threats of destruction. To preserve them, a Bengaluru-based not-for-profit organisation has procured a highly advanced multispectral imaging technology to capture their images. The technology is currently being used on rare texts in the Ashta Mutts of Udupi.

What is special about multispectral imaging is that it can capture texts in manuscripts that are affected by pests, fungus, over written, scribbled, blackened or scraped and cannot be seen with bare eyes. It uses infrared rays and ultraviolet rays to retrieve texts.

Its importance

“Mapping of knowledge is important in the current context. People are not bothered about these manuscripts because they do not see a direct relation with them and understand the importance of the stuff in it,” says P.R. Mukund, professor, Electrical Engineering, at Rochester Institute of Technology and founder of Bengaluru-based Tara Prakashana. “We have brought the technology for the first time in the country and the services would be offered for free. Our aim is to preserve the important written scripts in the country for posterity,” he said.

Tara Prakashana has acquired the imaging system from the U.S.-based MegaVision, a leading digital imaging company, that has worked in similar projects across the world and MegaVision president Ken Boydston has been training people in handling the multispectral imager over the last week.

Prof. Mukund’s interest in developing technology that would help conserve the knowledge for posterity started more than a decade ago when his guru Bannanje Govindacharya sought his help in conserving the 800-year-old Sarvamoola Grantha, authored by Saint Madhvacharya. The text is in the possession of Palimar Mutt and was found to be in bad shape in 2006.

“At that time, I did not have any idea about processing of manuscripts. Help came from a fellow professor from the imaging department at Rochester,” said Prof. Mukund. Since then, more than 3,000 rare manuscript bundles have been digitised, a small part of which has now been published into 500 archival books and nearly 1,000 more archival books will be ready shortly. Currently, ancient texts belonging the lineage of Saint Madhvacharya that are in the possession of the Ashta Mutts in Udupi are being digitised using the technology.

For Mr. Boydston, his association with the project comes from his love to protect ancient works, though he says cultural imaging is still not profitable. “I get to meet people who really know stuff. Even if no money is being paid, there is a lot of stuff to do. Objects [antiquities] have great value. Experts know historical contents and to be in the project is a great honour,” he said.

“We want to make the imaging complete and accurate following which several bundles of copies can be generated to preserve the knowledge for future generation,” said Mr. Boydston.

The next stage

The conservation efforts does not stop at capturing the images of manuscripts. While creation of e-library of manuscripts for the scholars to retrieve and research is currently under way, Tara Prakashana has published about 500 books of manuscripts.

“We have used the acid-free cotton archival paper for publishing these manuscripts. These special papers can last another couple of hundreds of years,” said Prof. Mukund.

To enhance the time span of the texts captured in images, a patented technology developed by Prof. Mukund called the wafer fiche, is being used. Using photo lithography technology, the images are imprinted on silicon wafers. “These copies can last for thousands of years,” he said.

Defence Minister Nirmala Sitharaman rolled out a red carpet of opportunities in local defence and aerospace manufacturing to global investors as she launched Aero India 2019 here on Wednesday.

As the 12th edition of the biennial international military and civil expo and air show opened at the Air Force Station Yelahanka, the gathering and airmen showered tributes to Wing Commander Sahil Gandhi, who was killed during a rehearsal on Tuesday.

“Aero India 2019 endeavours to put India as the global runway of a billion opportunities,” Ms. Sitharaman told a gathering of a few thousand invitees. Ministers, heads of global defence aerospace companies, corporate and government policymakers, military brass, entrepreneurs, delegates and exhibitors from across the world were at the event.

The chiefs of the three Armed Forces — Air Chief Marshal B.S. Dhanoa, Admiral Sunil Lanba and General Bipin Rawat — were in attendance at the show organised by the Ministry of Defence.

Minister of State for Defence Dr. Subhash Bhamre, Union Ministers D.V. Sadananda Gowda and Suresh Prabhu, Defence Secretary Sanjay Mitra, Secretary-Defence Production Dr. Ajay Kumar and Defence Research and Development Organisation (DRDO) Chairman Dr. G. Satheesh Reddy were at the event.

Chief Minister H.D. Kumaraswamy highlighted Bengaluru’s establishment of itself as the country’s capital in design, research and production in aerospace and defence.

After many years, the edition brings civil aviation back to a largely military show. The Ministry said it was the biggest so far, with 403 exhibitors and 61 aircraft in static or flying displays.

‘Missing man’

Three IAF fighter jets and a Rafale aircraft paid an aerial tribute to Wing Commander Sahil Gandhi, who was killed in a midair mishap during a rehearsal on Tuesday. The Indian jets Tejas, Sukhoi Su-30MKI and Jaguar flew past in a formation called Missing Man. The pilot of a French Rafale fighter in a flying demonstration made a sombre flypast for the killed airman.

Light Combat Aircraft (LCA) did a jaw dropping vertical climb called the Charlie in memory of the late Atal Behari Vajpayee.

3D frame launched to assist minimal invasive neurosurgery

According to Venkataramana, the cost of this machine is one-third the cost of the other machines available in the industry.

Bengaluru :

Medical science and engineering technology have come together to bring out a stereotactic frame, 3DR Stereotactic System, which will be used in performing stereotactic and functional neurosurgery. Bengaluru-based Brains Hospital, a neuro spine centre, in association with Mahalasa Medical Technologies, has designed the 3DR Stereotactic System.

According to Dr N K Venkataramana, founder chairman of Brains Hospital, and a chief Neurosurgeon, “This is a versatile machine which can be used during MRI, CT scans, and during surgeries that are carried out for treating tumours, epilepsy and other brain-related diseases.”

According to Venkataramana, the cost of this machine is one-third the cost of the other machines available in the industry. “I can proudly say this is manufactured under Prime Minister’s Make in India concept,” he added.

Launching the product on Tuesday, Union Defence Nirmala Sitharaman Minister said, “One should look at funders from India and not outside India. Bengaluru is blessed as it has all kinds of people, including funders.”

How this frameworks

This is used to carry out minimally invasive surgery. This frame is fixed to the head that guides the surgeon to reach specific targets in the brain. Stereotactic surgery or stereotaxy makes use of a three dimensional coordinates to locate small targets inside the brain and to perform procedures on them such as ablation, biopsy, lesion, injection, stimulation, implantation, and radiosurgery.

Community radio: making waves in Karnataka’s countryside

Sarathi Jhalak, a radio station in rural Karnataka run almost exclusively by women, takes on everything from menstruation to lake pollution

The only thing that sets apart the nondescript building from other houses in Anungondanahalli village in Karnataka’s Hoskote district is a board announcing the radio station. RJ Sunil has been waiting for us and shows us around.

The living area is bare save for a big board on the wall; the kitchen has a medium-sized, all-important transmitter; and the bedroom serves as the radio station. There is a wooden door with a glass window through which I can see the RJ. On top of a large table that occupies most of the room are the mixer and microphones. Sensible shelving against a wall has a small portable radio on it.

This is Sarathi Jhalak, a community radio station, run almost exclusively by women and one that has forged a vital connect with its largely rural audience, hosting programmes on everything from menstruation and lake pollution to alcoholism and finance.

“Even before Mann Ki Baat, we had Manadallada Matu (Talk of the heart),” chortles Shamantha D.S., the journalist who started the station in 2012. It reaches some 100 villages within a 30 km radius. This particular show, which aired at night “had so many female listeners,” says Shamantha; “they would call and speak about all their issues.”

Sunil sits behind the desk. The journalism graduate tells us that he barely spoke for the first three months that he worked here. “I was so scared.” It’s hard to tell, looking at him run the station with confidence now.

RJ Nagamani joins us and prepares for the afternoon show. Nagamani has studied till Class X, but says her work with Sarathi has made her “ articulate and knowledgeable.”

Friendly neighbourhood

Sunil decides to interview our photographer. He puts on his headphones and after a silent countdown with his fingers Sarathi Jhalak goes on air.

As they chat, a farmer drops in with his son and sits down with me outside the studio. “I want my son to do better than me,” the farmer says, “I work in the hot sun for ₹400 a week. Maybe Sunil can get him a job.” I am told that another farmer had walked in the other day to complain about a government hospital doctor who had wanted money for treatment. Parents bring their children to the station so the RJs can give them a pep talk.

Shamantha has trained Sunil and the three women RJs to speak simply and from their heart. “Instead of using clichéd phrases like ‘mahila dourjanya’ or sexual harassment of women, I tell the RJs to use a story that highlights it. That way people will listen.”

Nagamani tells me about a programme she did with girls from a nearby high school. They discussed menstruation and the disposal of sanitary pads. When there were reports from another part of the country of children falling sick from their midday meals, the RJs urged parents to check if the vegetables and vessels were being washed well. The women RJs are looked upon as friends by the villagers.

Speaking out

Some like Kala, (who has now quit for other opportunities), became minor celebrities. Nagamani’s children’s friends and their parents hold her in high regard. “My husband is very proud of what I do,” she says.

Shamantha recalls the time she had first come to the region with a group of journalists to conduct a media literacy programme nearly 15 years ago. Almost every woman was illiterate here. “I would tell them to listen to the radio while doing the housework.” After thorough background checks by at least seven different government departments, Sarathi Jhalak got its licence in 2012 and a funding of ₹5 lakh from the government. Hoskote was the obvious choice of location because Shamantha had worked there earlier. Around the same time the Women and Children’s Department of Anugondanahalli wrote asking her to start educational programmes for women. “It became easy for me,” says Shamatha.

Cost factor

But there have been hurdles too. For one, recurring expenses are high. The radio station has been approaching nearby schools and colleges to advertise with them. Though community radio is for and by the people, Shamantha believes that it is not fair for the government to expect RJs to work without pay. Her family pays Sunil ₹15,000 while Nagamani gets a token ₹3,000 a month. The station is always cash-strapped and requires at least ₹2 lakh a month to run. “We could then hire technical support, more RJs with better pay, better equipment, and document our popular programmes.” Encouraging stations like Sarathi Jhalak makes sense at the grassroots level.

As Shamantha says, “A community radio station like ours is not an alternative medium, it is a powerful one.”

The freelance writer believes that everything has a story waiting to be told.

Mangaluru professor’s Tuberculosis app to be upgraded

The app allows healthcare professionals who handle TB patients to calculate the right BMI and nutrition levels.

Bengaluru :

After N-TB app developed by a Mangaluru professor and his team gained popularity among doctors and Revised National Tuberculosis Control Programme (RNTCP), the team has been approached by the Ministry of Health to upgrade the app and make it more patient-friendly.

The developer of the app, Anurag Bhargava, professor of medicine at Yenepoya Medical College in Mangaluru, says, “The present app is definitely of help to the doctors and nurses advising dietary counselling, which is a major part of treatment of persons with Tuberculosis (TB). We need to upgrade the app to make it more people-oriented.”

In the new app, according to sources, the Ministry of Health also plans to include ‘Nikshay programme’, where registration and monitoring of TB Patients will take place online.

“The existing NT-B app provides information on nutrition, as under-nutrition could prove to be fatal for those with TB. This is the critical indicator that will be shown in the app, to help in dietary counselling. The app also demystifies dietary counselling by calculating the nutritional value of food. Weight is an indicator that is often monitored when treating TB, but height too is critical in getting the actual picture,” explains Bhargava.

The app allows healthcare professionals who handle TB patients to calculate the right BMI and nutrition levels. This app was developed based on the guidance document on nutritional care and support for patients with tuberculosis in India, that was released by the RNTCP last year.

The students took five months to create the device

Bengaluru :

Two students from MVJ College of Engineering have developed a device called  ‘bBook’ that converts text into braille in real time. Once a person with a visual impairment places the device over the text, it uses the six pins on its surface to convert the text.

A small camera in the bBook is used to scan text, which is then processed and the data generated is used to drive a braille unit. This unit gives the input character equivalent to braille. “A person can also download the latest news articles. A specially designed audio interface will be available, which will enable the user to use voice-control,” said Rohit Natesh, a student at the college.

The device can also be connected to mobile phones in order to receive notifications from the bBook application. It works in three speeds – slow, medium and fast – that is 4 seconds, 2.5 seconds and 1.5 seconds. They have been working on the device for five months now. “It has been a pleasure to work with my students. We hope to receive more feedback from blind schools,” said Desikan Srinivasan, assistant professor at MVJ College of Engineering.
