THX Audio Concept While sitting in a theater or in front of a home theater system we all have wished to get the best seat to get the best view and the surround sound effect. In the case of a speaker or any audio system there exists a spot called the sweet spot, where the effect of surround sound is at its best. We can feel a slight change in its features even if we are sitting a little away from the spot.  Most f the technologies available today have been able to produce only one sweet spot to get…

Piccolo Piccolo can be said as the perfect companion for a graphic designer or an engineer as it helps him to sketch his creativity. Piccolo is a small pocket sized robot which uses servo mechanism for developing and deploying the accurate 2D or 3D output. Like all other robots, this one also works according to CNC technology. CNC is the acronym of Computer Numerical Control. Here the computer converts the design produced by the computer aided design software (CAD) into numbers. These numbers denote different coordinates – that is X, Y and Z in a graph. This technology is employed…

Lytro Light Field Camera Since its invention, the technology behind a camera has developed a lot beyond imagination. Nowadays, the device has become so sleek in design that it is integrated with other gadgets like mobiles and computers. To take a good photo, a photographer needs to use a camera with good resolution and focus. What if the camera had a technique by which the focus could be provided after the photo was taken? This would give the photographer enough time to sort out the correct focus required for the picture taken. This technique has been introduced in the “lytro…

Special Contact Lens In the movie “The Terminator”, we see Arnold Schwarzenegger check out the complete profile of the subject he is about to face.  A similar technology has been developed by Babak Parviz, an electrical engineer at the University of Washington. Babak designed a lens that can be used to display a single pixel at a time. This display can be switched on and turned off through a wireless medium. The lens consists of an IC which stores the energy, along with an LED that shoots the light towards the eyes. But, the lens is not capable of intercepting…

Waterless Washing Machine – Laundry Orb New inventions have made strainful works always easier for people. Let us take an example of a washing machine. In early days, people used to wash their own clothes by hand and scrub all the dirt away using a brush and detergent. Later, the washing machine was invented, which simplified laundry cleaning. The device was further developed to produce semi-cleaners and lately fully automatic washing machines. A new concept has been introduced by a a designer named Elie Ahovi, which works under the principle of magnetic levitation. The device, named as “Laundry Orb” consists…

The Hollywood film industry went to a whole new level after 3-D movies like James Cameron’s “Avatar” to the latest “Underworld Awakening”. The perspective of watching movies through a whole new dimension is believed to have brought movie fans closer to reality. But, people often complain about headaches and other eye problems after watching a movie continuously for 2 to 3 hours.   But, due to the awesome movie effects, most companies are ignoring this problem and are introducing more and more 3D enabled gadgets like 3D televisions and smart phones. Smart phones like LG Optimus 3D and HTC evo 3D…

Smallest Data Storage Device There will be a time when all the major technologies in the world will be in nanoscale. Recent developments have been undergone in daily used electronic gadgets like mobiles, computers, laptops and so on. As a part of this, a group of researchers from IBM and CFEL (Centre for free-electron Laser Science) have been successful in developing the world’s smallest magnetic data storage unit. The newly invented unit needs only 12 atoms for storing one bit. That is, 96 atoms for storing one byte. In a conventional memory storage unit a byte consists of half a…

laser cell construction Cyclops, a superhero from the famous comics “X men” has been the favorite of many people across the world. In the story, the character produces powerful laser beams by optical blast from his eyes. This fiction has become a reality by the joint efforts of Seok-Hyun Yun and Malte Gather, two physicists at Massachusetts General Hospital.  They were able to develop a technique by which laser can be produced from human cells. The device used to produce this laser consists of the same components that are used to produce a real time laser. That is, a pump…

3D Transistor A transistor is the fundamental building block of all electronic devices.  .  A transistor can be defined as a device, which is used to amplify signals and power. Integrated circuits are used in making of chips inside electronic gadgets such as smart phones, laptops and so on. Researchers in Purdue and Harvard Universities have created a new type of transistor that will make the Integrated circuits more compact. This transistor is made from another material other than silicon and as the name suggest, a 3-D structure is given to the device compared to the conventional flat chips. Nano…

Smallest Electronic Circuit Technology has been evolving time to time, from complex wired circuits to Integrated circuits(IC). Nowadays almost all electronic gadgets like smart phones, computers, global positioning systems(GPS), tablets and so on use Integrated circuits as they are more compact and efficient. In this era of nanotechnology, scientists are scaling every possible technology to nano scale without compromising its efficiency. Nano circuits were made by scaling Electronic circuits in the nano range, and that too, by rectifying the disadvantages of Integrated circuits like heat dissipation. Recently a team of researchers headed by Guillaume Gervais of McGill’s Physics department and…
