Fastest wireless data transfer using infrared tech

Back around the turn of the century, infrared ports for wireless data transfer over short distances were commonplace on many mobile devices. But it wasn’t long before infrared communication technology was kicked to the curb in favor of the more versatile radio-based Wi-Fi and Bluetooth technologies. Fraunhofer researchers are looking

A bug-size flying robots, by Studying butterfly flight

U.S. defense agencies, which have funded this research, are supporting the development of bug-size flyers to carry out reconnaissance, search-and-rescue and environmental monitoring missions without risking human lives. These devices are commonly called micro aerial vehicles or MAVs. “For military missions in particular, these MAVs must be able to fly successfully through complex urban environments, where there can be tight spaces and turbulent gusts of wind,” said
