electrical load without the use of interconnecting manmade conductors (i.e., wires)”. Much of the technology exploited in the current (and still-early) implementation of WET has precursors in 19th century research by engineering visionaries such as Nikola Tesla. Broadly, there are two categories of WET: far-field (FFET) and near-field energy transfer (NFET). As the grand majority of research and development lies with NFET, FFET will not be discussed. Among the reasons underlying the preference for NFET

How we ended up with 15 different kinds of plugs and sockets? There is 15 different types of power plugs and sockets in the world and those are named with letters from A to O. Main question is why we have those 15 different types of power plugs instead of one in whole world. All of this plugs works either with 50 Hz frequency or with 60 Hz and the voltage variate between 100 to 240 V. Around 80% of all the countries in the world use voltage between 220 to 240 V and the rest 20% use voltage between

Wireless Networks & Network Security ISSC 340 Professor Vijay Venkatesh James Lange 08/13/2013 Wireless Networks are somewhat new technology in comparison to the know-how that makes them possible. The knowledge regarding wireless technology goes back about 200 years. One of the first individuals deserving recognition for today’s wireless networks is a scientist, inventor and politician named Benjamin Franklin. In 1747 he had built a model that showed how electricity could move through

Wal-Mart uses technology to improve productivity, communicate more efficiently and track customers and goods daily. In fact, most of the success relies on technology for almost every aspect of their business. Although there are many types of technology available, going digital doesn't have to intimidate business owners. It can all be broken down into understandable chunks of functionality. Wal-Mart systems keep track of every item in their inventory, ensuring they do not run out of stock or order

Research Paper Wireless Electricity Imagine the following scenario unfolding. Nick has had a long day at work on Friday and is ready to go home. The whole twenty minute drive home all he can think about is how excited he is to take his family on a weekend trip to the beach. As he pulls into his driveway, he notices that the front light isn’t on like usual, but the fact is quickly lost in his mind as a thousand other thoughts are clamoring for his attention. Just as he steps through the

DARPA, DSTA, RF, cockroach intelligence. or mobile for use in industrial automation applications. “ All these definition do give us a rough idea about what comprises a robot, which needs to sense the outside world and act accordingly. There are motors, pulleys, gears, gearbox, levers, chains, and many more mechanical systems, enabling locomotion. There are sound, light, magnetic field and other sensors that help the robot collect information about its environment. There are microcontrollers powered
