It is a reading machine for the visually impaired and illiterate people, where any printed or digital document can be accessed in the form of speech output. The device uses a contact line scanner for acquiring the image of a printed document.
The system, which works 24×7 to maintain the room temperature in the range of 15-20°C throughout the day and night, developed by Pluss Advanced Technologies, Gurugram, and the prototypes tested at the Indian Institute of Technology, Mandi, Himachal Pradesh can be a sustainable clean energy source for hill areas providing for both heating and lighting needs.
The mission will be launched using Polar Satellite Launch Vehicle PSLV in XL configuration. With seven payloads, the satellite will continuously face the sun and send round-the-clock imaging of the sun which will aid in study related to the solar emissions, winds and atmosphere.
Online monitoring of breath has gained a lot of attention recently as the breath pattern of an individual provides important information on the person’s health condition. Monitoring the breath pattern can help in detecting different diseases like asthma, sleep apnea, and more.
Dr Rajan Choudhary, Associate Professor at the Department of Civil Engineering, IIT Guwahati, has developed a technology for the use of industrial waste steel slag, a by-product of steel making in open-graded asphalt friction courses (OGAFC) under the Waste Management Technologies (WMT) program of Technology Development and Transfer Division, Department of Science & Technology.
While the technology Isro is aiming to eventually have is one that will allow it to transfer humans from one vehicle or spacecraft to another, the immediate goal is to enable refuelling of spacecraft to give them a longer life and also transfer other crucial systems to an existing spacecraft, by transporting another to space.
Scientists at NAL, a CSIR institution, used electropolishing technology to remove irregularities and defects on the surface of needles using a mixture of phosphoric acid and sulphuric acid as an electrolyte.
Scientists at Department of Biotechnology’s Mohali-based National Agri-Food Biotechnology Institute have developed non-toxic and edible composite coatings based on wheat straw hemicellulosic polysaccharide (WP) and stearic acid derivatized oat bran polysaccharide (SAOP) that promise to overcome the problems.
Knowing the property of silver in inhibiting the growth of bacteria, scientists at the Agharkar Research Institute (ARI), Pune have successfully carried out implant surface modifications by depositing a nano-scale thin film of silver on the titanium surface to address the challenge of implant failures, especially due to bacterial infections. ARI is a Pune based autonomous institute of the Department of Science & Technology.
The study by R Ramesh, IIA, V Mugundhan, RRI and K Prabhu, IIA, found that the release is broken and spans both over multiple locations and at different times. This finding can help us form a better understanding of time and location of solar flares that affect the ionosphere and radio communications on Earth and also release energetic particles into space. The findings were published in the journal The Astrophysical Journal Letters.
