“TELECOM” a minefield of opportunities

Written in 17-9-2009 by | No Comments

In this recession all the industries in India got down and faces some extraordinary loss. But the only industry which has continuous growth, do you know the answer? Yes its “electronics” industry. First we see about the factors for its steady rise, first, aggressive marketing, then falling tariff, and finally cutthroat competition.

Indian telecom is one of the fastest growing industries in the world and is projected to become the second largest telecom by 2010. In April 2008 India overtook the US as the second largest wireless market and as a pointer to the increasing global influence of Indian telecom companies.

Considering that telecom is a booming sector even in times of the current economic recession the demand for employable individuals is open. The recruitment trend in the telecom industry further confirms the statement. Large telecom players BHARTI AIRTEL, HUAWEI, TECH MAHINDRA, ZTE CORPORATION, NOKIA as well as loads of small and medium enterprises are in a hiring mode.

Lets hope Indian telecom industry will become first place globally within 2010. Make India a super power in 2020 as Abdul kalam’s favor.

Electronic lighting control

Written in 17-9-2009 by | No Comments

Electronic lighting control is an emerging application in power electronics. One common driver of this market is resulting efficiency. The addition of a small, low cost, micro controller unit increases efficiency besides providing other benefits in lighting power supply systems.

For example, an MCU can be added to LED lighting system for efficiently controlling the brightness of the LED over its entire operating range. Similarly for fluorescent bulbs, which are also very efficient source of light, electronic control via an MCU allows the bulb to any level thereby increasing efficiency.

Other benefits of using an MCU are active power factor correction (PPC) to further increase the efficiency, battery charging for portable lighting applications and the opportunities to integrate communication protocols such as DALI and DMX512.

Nanotube sensor to detect nitric oxide gas
Nitric oxide is difficult to detect because it is very unstable. Monitoring nitric oxide levels in living cells will help researchers figure out its role in the cancer and other diseases. It would also allow closer study of nitric oxide releasing cancer drugs. Biologists could use these sensors to study the effects of nitric oxide on the brain, where it acts as a neurotransmitter.

The researchers coated carbon nanotubes with a polymer designed to specifically attract nitric oxide. The polymer is wrapped tightly enough so that only small molecules can get through to bind the nanotube by an extra pair of electrons passed from the polymer to the nanotube. The sensor is activated by near infrared light , which easily penetrates the human body. The team plans to start testing the sensors in living animals and is working on similar sensors that can detect molecules other than nitric oxide.

Microchip based on DNA structure
International Business machines and California Institute of Technology is developing microchips based on DNA structure. As designers struggle to cut costs, chipmakers attempt to develop smaller chips to address this challenge. Artificial DNA nano structures provide a cheaper framework to build microchips, which are used in many electronics devices like mobile phones.
