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.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
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.
