making it possible to deliver twice as much power from a given area of panels. The trick is to first turn sunlight into heat and then convert it back into light, but now focused within the spectrum that solar cells can use. While various researchers have been working for years on so-called solar thermophotovoltaics, the MIT device is the first one to absorb more energy than its photovoltaic cell alone and could dramatically increase efficiency. REFERENCES: http://news.mit.edu/2016/hot-new-solar-cell technique, wounds were healed both internally and externally and temperature can be adjusted based on the requirement. The team then developed a pen-sized laser that used optic fibres. Of the fibres, one is used to detect the carbon dioxide-powered infrared lasers falling on the wound. The other fibre, which leads from the pen to the infrared sensor, ensures the temperature is maintained in the suitable range 60–70 degree Celsius. The pen is easily used by moving the tip along the surface of the wound with the water-soluble protein solder. This laser pen can be used for migraines, burns, lower-back pain, and swelling, among other things. It can also be used to rejuvenate new cells and tissues. A.Babitha EEE Dept, III year PORTABLE LASER PENS TO HEAL WOUNDS: Portable laser pens are used as an alternative to traditional needle-and-thread surgeries. Even in carefully performed microsurgeries, there is always the chance of infections or scars. To avoid that, the use of lasers to heal wounds has increased over the last decade. Initial day’s doctors used carbon dioxide lasers to close up wounds where they found difficulty in controlling temperature. By using laser welding REFERENCES: https://yourstory.com/search?q=portable%20l aser%20pen Jutur Meera ECE - III year "People who are afraid to fail can never experience the joys of success." - Pete Zafra
Speed Detection of Moving Vehicle Using Speed Cameras! In today’s fast moving World, the accidents are increasing at a very fast rate. One of the major causes of these accidents is over a speeding of vehicles. A major step has been taken rather to increase the road safety, so as to minimize the accidents. One of a major development was the introduction of speed cameras. This camera, usually containing radar is electronic devices those working are still a mystery to most electronic hobbyists. The principle of these speed cameras is Doppler Effect used in radar. related crashes and injuries their use expanded to many other areas of Great Britain. The equipment is expensive to buy, operate and maintain and their support in prosecution procedures also much substantial administration costs. However and the cost are small compared to the benefits of society and the economy Speed cameras are recommended under use to reduce road casualties. Since these cameras save lives of road users the speed camera is also known as" safety cameras" Speed camera uses the basic principle of Doppler Effect and RADAR technologies. We can discuss the Doppler Effect in these speed cameras and other working in these cameras. So the roads safety strategy was published or introduced to support the new casualty reduction targets. The main reason is speed of vehicle. We use traffic lights and other traffic manager to reduce the speed. One among them is speed cameras on the side of urban and rural roads, usually placed to catch transgressors of the stipulated speed limit for that road. The speed cameras, the solely to identify and prosecute those drivers that pass by them when exceed the stipulated speed limit. At first glance this seemed to be reasonable that the road users do not exceed the speed limit must be a good thing because it increases road safety, reduces accidents and protect other road users and pedestrians. So speed limits are good idea Speed cameras were introduced in west London in 1992 and following their success in reducing speed REFERENCES: http://www.seminarstopics.com/seminar/spe ed-detection-of-moving-vehicle-using-speedcameras B.Prasanna EEE - III year ROBOBEE Engineers program tiny robots to move, think like insects!! In the recent days, engineers had a great success on building the tiny, insect like robots to move and which can actually think like the insects. They programmed them to autonomously like real insects. A group of cornell engineers has been experimenting with a new type of programming that mimics the "No matter how small, acknowledge the achievement." - Greg Henry Quinn
