Keep Lighting Green from Start to Finish With Proper Packaging and Disposal of Used Fluorescent Lamps

Fluorescent lamps are a popular lighting option for businesses and consumers that are looking for ways to conserve energy and cut down on wastes. Since mercury - a very useful but very toxic element - is used to conduct the charge in fluorescent lamps, these benefits can come at a significant environmental and health risk.

Intelligent Energy Management

Smart meters – intelligent devices to measure consumption – make it possible to read and control power consumption, even of private households, while away from the property. New software shadows the electricity meter and that ensures energy consumption is adjusted accordingly.

Process Yields High-Energy-Density Plant-Based Transportation Fuel

A team of University of Wisconsin-Madison engineers has developed a highly efficient, environmentally friendly process that selectively converts gamma-valerolactone - a biomass derivative - into the chemical equivalent of jet fuel. The process preserves about 95 percent of the energy from the original biomass.

Electric Motor Efficiency Regulations: What Motor Manufacturers, OEMs, and Motor Users Need To Know

The Energy Independence and Security Act of 2007 (EISA), which restates the definition of General Purpose Electric Motors, goes into effect on December 19, 2010. For the first time, OEMs are going to be held accountable for the efficiency of motors in their equipment.

Making Sense Out of SOUP (Software of Unknown Pedigree)

Software test tools have been traditionally designed with the expectation that the code has been (or is being) designed and developed following a best practice development process. Legacy code turns the ideal process on its head. Although such code is a valuable asset, it is likely to have been developed on an experimental, ad hoc basis by a series of “gurus” — experts who prided themselves on getting things done and in knowing the application itself, but not necessarily expert at complying with modern development thinking and bored with providing complete documentation. That doesn’t sit well with the requirements of standards such as DO-178B.

Multicore Processing: A Technological Dead End?

The computing press is full of discussions about multicore systems, defined here as single-chip computers containing two or more processing cores each connected to a common shared memory (Figure 1).

These devices are being presented as the solution to the performance problems faced by embedded systems, but in fact, multicore may be more of a problem than a solution.

Understanding Virtex FPGAs

With each new generation of FPGA devices, Xilinx continues to push the performance envelope to match the ever-increasing requirements of target applications. The recent announcement of the Virtex-6 is no exception. More processing power, lower power consumption and updated interface features to match the latest technology I/O requirements are all part of the new devices. While it might be easy to assume that faster, bigger, more powerful is better, it’s important to understand how the latest FPGA innovations actually deliver this higher performance to best match the device to the specific requirements of the application.
