U.S Soldiers Develop High-tech Gadget for Better Night Vision Posted: 05 Jul 2011 05:59 AM PDT The U.S Army is famous for their military gadgets that are used to hunt down enemies and also navigate a battlefield at night. They began by using night goggles. But there were complaints about these goggles for being noticeable by the enemies. Another problem is that they had no way to track their exact location or the direction to head to. So, they started installing Global Positioning System (GPS) enabled devices so that the soldiers can find their way through the dark. But, this technology also has its drawbacks as the light from its display can easily help his enemy to sort out his position. Besides, the combat trainer will find it difficult to handle a weapon and the gadget at the same time. All these problems have urged the researches at the Army Research Office to develop a new gadget that will help the soldiers to easily feel the way through the dark. The basic idea is to get directions by the sense of touch. Thus, this device is known to be haptic in nature. The device consists of a vibrating belt along with 8 small actuators. These actuators are named as tactors and are placed in 8 different...

Here Comes the Strongest Magnetic Field to be Ever Created Posted: 04 Jul 2011 10:03 PM PDT Germans, who are known for producing the most promising ad efficient mechanical and electrical designs, have lately created the strongest magnetic field in one of their labs. This new development is considered as a new world record and was created by the researchers at the High Magnetic Field Laboratory Dresden (HZDR). For developing such a structure, the researchers used a 2-layer, 440 pound copper coil, which is almost equal to the size of a water bucket. By their unique design, they were able to break the previous record of magnetic field produced (89 teslas) by creating 91.4 Teslas. The field created lasted on for a fraction of a second. The figure given below shows a U.S Navy sailor coiling the wire for an electric motor. The same process was carried out in the German lab, where the 440 pound copper coil was wrapped to produce a very strong magnetic field and hence a highly powerful electromagnet. Strong Magnetic Field The 91.4 teslas produced by the electromagnet is very high when compared to a conventional copper coil used for industrial purposes that produces something less than 15 teslas. The same machine would just be ripped off if such a high amount...
