Wireless Charging of Moving Electric Vehicles

If electric cars could recharge while driving down a highway, it would virtually eliminate concerns about their range and lower their cost, perhaps making electricity the standard fuel for vehicles. Researchers have wirelessly transmitted electricity to a nearby moving object, which could advance...

Plastic Optic Fiber—An Evolving Technology

Plastic Optic Fiber (POF) is an established, continually evolving technology available since the early 1980s. From the outset, it was a technology not highly visible for years. At times, it was utilized as a media product within another product, attached to a variety of opto-couplers or light sources....
