His may not be a household name, but the telecommunications world knows him well. Peter Delfyett, associate professor at the Center for Research and Education on Optics and Lasers (CREOL) at the University of Florida, invented the world's first commercially available modelocked semiconductor laser diode from a U.S. manufacturer. The laser releases the shortest and most powerful optical pulses ever generated from a semiconductor laser diode. He demonstrated a laser system using fast semiconductor laser and high power solid-state amplifiers as a medical imaging tool. This device can look inside the human body, non-invasively, without using ionizing radiation such as x-rays. He might be young, but his list of accomplishments is impressive. At 37, Delfyett won the Presidential Grant honoring young engineers. In 1993, he received the Black Engineer of the Year Award for Most Promising Engineer. Delfyett currently holds six patents. He also helps bring science to students of all ages. One of his projects includes a program to foster science experiments in the schools of Harlem.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
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.
