NATIONAL: ENGINEERING / SCIENCE & TECHNOLOGY /DEFENCE / AVIATION: Hindustan Aeronautics Ltd (HAL) Delivers 16th Advanced Light Helicopters (ALH Mk-III Maritime Specific) to Indian Coast Guard

Hindustan Aeronautics Limited (HAL) has handed over the last of the 16 Advanced Light Helicopters (MK-III, Maritime role) to the Indian Coast Guard at a programme here on Tuesday.

The chopper was handed over to DG, Coast Guard, V.S. Pathania, in the presence of senior officials from the Indian Coast Guard and HAL.

“We are proud to be associated with HAL and happy to issue a Letter of Intent (LoI) for nine more helicopters. Despite Covid-19, HAL delivered all the helicopters at the shortest time with seamless production activities and this allows us to strengthen India’s maritime security,” Pathania said.

The DG had signed a contract with HAL for the supply of 16 ALH Mk-III in March 2017.

C.B. Ananthakrishnan, CMD, HAL, said a unique feature of the contract has been the performance based logistics (PBL) – the one stop solution for maintenance of these helicopters by HAL.

“This will serve as a benchmark for all our future contracts and boost our resolve to work with private partners to speed up the work in the interest of all our customers and strengthen Make-in-India activities in the defence eco-system,” he said.

S. Anbuvelan, CEO (Helicopter Complex), HAL, pointed out the major challenges in execution of the contract that included integration of new systems sourced from foreign OEMs, conducting flight trials for certifications and overcoming disruptions in the supply chain due to lockdowns.

ALH Mk-III is indigenously designed, developed and produced by HAL. The company has so far produced more than 330 ALHs, a versatile helicopter which has logged more than 3.74 lakh flying hours.

INTERNATIONAL: SPACE & SATELLITES: Bengaluru-based Youth-Led Start-Up ‘Digantara’, to Send 40 Satellites to Compile Space Debris Data

The race to space has the downside of polluting it. A Bengaluru-based start-up plans to send out a constellation of 40 satellites that will gather data on space junk in the low-earth orbit (LEO).
The satellites that will be launched in early next year will gather information on millions of pieces of debris that litter LEO, which NASA describes as an “orbital space junk yard”.

Digantara, the start-up launched by three young engineers, has taken upon itself the mission to help clean up LEO. 

Space junk can reach speeds of up to 18,000 miles per hour, according to NASA. Many of them range from 1 cm to 10 cm in diameter. Most of this orbital debris comprises “human-generated” objects such as parts of spacecraft that have long disintegrated, rocket and satellite components, and very small flecks of paint from spacecraft and whole satellites.

“The ones which are 1 cm in diameter are estimated to be a million. Besides, international space agencies have determined that they are aware of only 4 per cent of objects in space. The data for 96 per cent is still missing,” said Digantara chief operating officer Rahul Rawat, who is only 23 years old.

Digantara, which is incubated at Bengaluru’s Indian Institute of Science, sent out a small satellite, a payload about the “size of a shoe box”, according to the start-up’s CEO Anirudh Sharma, on June 30 this year to gather information on space weather, including radiation, violent storms and other phenomena that can be potentially harsh for spacecraft and burn or fry them. 

While this lone satellite has been sending out data to ground sensors, Rawat pointed to Elon Musk’s SpaceX Starlink constellation of 40 of 49 satellites that were “lost in a single blow” when they encountered a gigantic “solar paroxysm” that burned the spacecraft and cost the company $100 million in February 2022.

It is precisely to avoid satellites getting caught up in such “solar outbursts” or other violent geomagnetic incidents that Digantara expects its own satellites – and the information it will send back to its ground sensors – to come to the rescue of space companies with ambitions of sending out satellites. 

“We are the only start-up of its kind in India though there are competitors in the US and Canada,” Rawat said, adding the gathered data can help firms that are into remote sensing and insurance where risk analysis reports will be important.

SCIENCE & TECHNOLOGY: INNOVATION: Kaviraj Prithvi’s Team Wins ‘Best Social Impact Business Idea’ for ‘Tactall-Braille Printer’ at Startup Fest ‘SmartIDEAthon 2022’

A portable and inexpensive Braille printer, an invention by a Karnataka student, won the Best Social Impact Business Idea at the SmartIDEAthon 2022, a nationwide pitch fest organised by Startup India in collaboration with several universities.

Prithvi Systems and Innovations founder and chief invertor Kaviraj Prithvi’s team was one of the 1,200 shortlisted for the fest and has been working towards inventing assistive technolog

The Tactall, a mouse-sized portable printer, allows for easy printing in Braille and is relatively inexpensive, according to Kaviraj.

“Braille printers print in standard dimensions and they are often very large, expensive and standalone, averaging to about $2000 to $3000. We wanted to make it more accessible for people to print in Braille, especially as this was a common problem which I found out when I had visited a school for the blind,” Kaviraj told TNIE. While the printer is in its prototype stage, Kaviraj, who is also pursuing engineering physics at II T Guwahati, and his team of 15 members, are also working towards inventing other types of assistive tech.

“All of our inventions have assistive angle to them. When I was younger, I wanted to start a startup and I felt that everything that I invented should have a social angle and must help people,” he said.

Apart from the printer, Kaviraj is also working towards building a non-invasive way to monitor blood pressure, as well as a patented rotor control system and a suspension system for bumps. “The suspension system is being designed specifically for wheelchairs and other support vehicles, but it can also be used generally. The rotor system is specifically for helicopters, to allow for easier rescue operations and to lessen turbulence while transporting patients,” he said.

INDIAN RECORDS: KARNATAKA: HEALTH & MEDICAL SCIENCES / SCIENCE & TECHNOLOGY: Researchers at Indian Institute of Science (IISc) Develop Algorithm called (ReAl – LiFE) to Study Connectivity in Brain

Researchers at Indian Institute of Science (IISc.) have developed a new graphic processing unit (GPU) based machine learning algorithm called Regularised, Accelerated, Linear Fascicle Evaluation (ReAl – LiFE), which will help to obtain a better understanding and in the prediction of connectivity between different regions of human brain.

This algorithm can help analyse extensive data generated from diffusion Magnetic Resonance Imaging (dMRI) scans which helps scientists study the connectivity in the brain at a speed, which is 150 times higher than a regular desktop computer or existing state-of-the-art algorithms. The study has been published in the journal Nature Computational Science.

“Even though it is difficult to pinpoint the connectomes, we are trying to infer information highway network by looking at traffic flow patterns (if molecules are like cars). We look at the movement of water molecules in the brain and we try to infer where the wires are. The water molecules have to travel along the length of the cables (axons), which have connected various parts of the brain. By measuring these lengths of water molecules, we are able to infer which areas are connected,” explained Devarajan Sridharan, Associate Professor at the Centre for Neuroscience (CNS), IISc., and corresponding author of the study.
