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.
Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
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.
