March/24/2017 is a historical day for India After England, USA, France and Israel; India is a fifth county which develops his own navigation system for ships.  Secondly, after the democracy India first time export defence items. India gives three SONAR system USHUS-2 to Myanmar and the cost of this product is about 180 crore. USHUS-2  is developed by Naval Physical and Oceanographic Laboratory (NPOL), the only Defence Research and Research organisation (DRDO) lab in Kerala, India. Union Defence and Finance minister  Mr Arun Jaitley handed over  10 USHUS-2 to Indian navy too.   USHUS-2 USHUS-2 is an integrated submarine sonar suite, a state-of-the-art upgraded of existing USHUS sonar presently operational on the frontline submarine of Navy. USHUS will replace Russian sonar system. It is designed and manufactured by DRDO. The range of USHUS-2 is about 100 to 150 kms. 

Night vision is the ability to see in low light conditions. Whether by biological or technological means, night vision is made possible by a combination of two approaches: sufficient spectral range and sufficient intensity range. Human has poor night vision compared to many animals, in part because the human eye lacks a tapetum lucidum. Night vision technology Night vision technology, literally allows one to see in the dark. Pre 1940’s flares and spotlights were used for operations at night. It is originally developed for military use. With the proper night vision equipment, we can see a person standing over 200 yards (183 m) away on a moonless, cloudy night. History Due to the nature of these early night vision devices (NVD), they gave away tactical positions. Military scientist began to think of ways to improve night vision to gain a strategic advantage. The first-night vision devices were created during WWII. Functioned by placing an infrared filter over a se...

Touchscreen technology is the direct manipulation type gesture-based technology. A touchscreen is a source of input device and output device normally layered on the top of an electronic visual display of an information processing system.  As the name suggests touchscreen you have to touch the screen for any processing. It is sensitive to the touch of a human finger, hand, pointed figure nail and passive objects like a stylus. The user simply moves things on the screen, scroll them, make them bigger and much more. History The first ever touchscreen was developed by E. A. Johnson at the Royal radar establishment, Malvern, UK in late 1965. evidently, the first touchscreen was a capacitive type; the one widely used in smart phones now days. In 1971, a milestone in touchscreen technology was developed by doctor Sam Hurst, an instructor at the University of Kentucky research foundation. It was a touch sensor named ‘Elograph’. Later in 1974, Hurst in association with compan...

Graphene is an allotrope of carbon in the form of a two-dimensional, atomic-scale, hexagonal lattices in which one atom from each vertex. Graphene can be described as a one-atom thick layer of graphite. It is the strongest, thinnest material known to exist. Each carbon atom is sp 2 hybridized and it is bound to its the neighbors. History of Graphene One of the very first patents pertaining to the production of graphene was filed in October 2002 entitled, “ Nano-scaled Graphene Plates”. Two years later, in 2004 Andre Geim and Kostya Novoselov at the university of Manchester extracted single-atom-thick crystallites from bulk graphite. Geim and Novoselov received several awards for their pioneering research on graphene, notably the 2010 Nobel prize in physics. Structure of Graphene Graphene is a 2-dimensional network of the carbon atom. These carbon atoms are bound to the plane by strong bond by strong bonds into a honeycomb array comprised of six-memb...
