If you think light switches and thermostats are not very high tech, think again. EnOcean GmbH is shipping wireless modules that use energy harvesting techniques so no batteries are required. To meet the new thrust to manage lights and temperature using wireless technologies that offer more precise control, modules must be small enough to fit in a light switch and be cost-competitive with battery-powered systems. EnOcean's 1.5-inch square module gathers energy from solar sources while also monitoring minute changes in pressure, temperature, vibration and motion to generate electricity. A Microchip Technology controller manages power gathering and radio communications. A proprietary radio transmitter helps keep power demands low.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
A group of researchers at the Seoul National University have discovered a way to take material from cigarette butts and turn it into a carbon-based material that’s ideal for storing energy and creating a powerful supercapacitor.
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.
