Tadiran's TLM family of Military Grade Batteries is developed specifically for military and aerospace applications. These rugged, high-energy lithium metal oxide batteries feature an open circuit voltage of 4V, with a discharge capacity of 500 mAh (20 mA at 2.8V RT), capable of handling 5A continuous pulses and 15A maximum high-current pulses. TLM Military Grade Batteries are constructed with a carbon-based anode, multi metal oxide cathode, organic electrolyte and shut-down separator for enhanced safety. They also feature low self-discharge and a wide operating temperature range of -40 to 85C. These batteries comply with MIL-STD 810G specifications for vibration, shock, temperature shock, salt fog, altitude, acceleration (50,000 gn) and spinning (30,000 rpm), and conform to UN 1642 and IEC 60086 standards for crush, impact, nail penetration, heat, over-charge and short circuit.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
