NREL's new Open PV Web site lets users download information about installations, explore trends in photovoltaic markets.
This week, John told you about his experience with window shades that improve the energy efficiency of his windows. There are several things you can do to improve the efficiency of existing windows, including adding storm windows, caulking or weatherstripping, or using window treatments.
As I mentioned in yesterday's blog, I had insulated window quilts installed on most of my home's windows. I should have bought window quilts for all of our windows, but I refrained from doing so on two downstairs windows to save money (which, in the long run, I didn't). There were window...
There are many applications whose operating environments demand the use of an interconnect system with a high-reliability contact. If equipment is to be used where high shock and vibration or extremes of temperature are experienced, connectors based on a standard contact will not be reliable or rugged enough to guarantee signal integrity.
There's a lot of talk these days about installing new energy-efficient windows. Thanks to a Federal tax credit of up to $1,500, window advertisements, both print and radio and TV broadcasting, are aplenty. I don't want to knock energy-efficient windows. There are some great window...
Findings by the Office of Naval Research indicate that video games improve overall perceptual and cognitive abilities. While nothing new—the claim is nearly as old as Pac-Man, the irregular warfare we face today makes it more relevant than ever. Since Pong, video games have been castigated for everything from school truancy, to school shootings, to even global warming.
My point here is not to join the chorus of Toyota-bashers. Rather it is to point out that major software quality problems seem to be occurring with increasing frequency across more industries today – and they are definitely happening more frequently in the embedded industry.
Handheld electronic devices -- regardless of what they are used for or who manufactures them -- share one common denominator: a re-chargeable battery and, in most cases, a built-in charger circuit. When an external power source such as an AC adapter or a USB port is attached at the input terminal, the charger circuit will re-charge the battery.
Powertraveller has released the ultimate travel charger for on-the-go professionals, outdoorsmen, and techies alike—the powermonkey-eXplorer. With three charging methods, international adapters, and tips for nearly every portable electronic device, you’ll never be somewhere without power.
How can we make solar panels more efficient?
What is the next breakthrough in battery technology?
Microcontrollers offer engineers a variety of power-saving techniques. But using them effectively requires careful attention to tradeoffs in software and hardware at the start of a project. "Engineers must partition their application so they have a rough idea how long their microcontroller will stay in a sleep mode or in an active mode," said Mike Salas...
To find out more about the state of motor-control design in embedded systems, I recently talked with three engineers at Texas Instruments who work with motor-related hardware and software. "Motor control looks simple to start but it covers many disciplines so it's almost impossible to have one designer do everything," noted Miroslav Oljaca...
On Monday, Andrea pointed you to the redesigned EERE home page. While this blog usually focuses on resources from EnergySavers.gov and other sites that are specifically for consumers, we know that many readers are interested in broader energy efficiency and renewable energy information....
The continued increase in mobile handset functionality is being enabled by more powerful baseband and applications processor chips, which are more frequently coupled with memory devices using package-on-package (PoP) stacking.
The emergence of energy-efficiency standards and continued evolution of processing and feature sets to support new products that consumers/enterprises use in everyday life: DVRs, set-top boxes and modems, industrial handhelds, portable media players, bar-code scanners have changed the methodologies employed for addressing DC power conversion, management and distribution.
For good or ill, the military is often indistinguishable from a large corporation. While “employees” must conform to the company’s modus operandi, the company must engage its employees on their terms. In this day and age, that means technology. Thus, the military increasingly relies on video games and computers to recruit and train its “employees.”
The OSTAR Compact LED from OSRAM Opto Semiconductors has been developed specifically for use in vehicle headlights. This high-power LED is designed for Daytime Running Light (DRL) applications based on the use of light guides.
Solar energy has been called the wave of the future. MacroAir Technologies, a company founded on the very principal of innovation, is surfing that wave with the introduction of the MacroVoltaic fan. Receiving the highest certified rating, the MacroVoltaic fan is the only solar high volume low speed (HVLS) industrial fan on the market.
Ideas can come and go quickly. To harness the potential of new ideas it’s essential to follow the basics to select ideas for further refinement to suite the market.
I have a love/hate relationship with buses. I love that they save me gasoline, are more efficient than driving a car, and reduce my greenhouse gas emissions. However, I hate them when they're running late! But there is one category of buses that I'm particularly fond of – those that...
The freshest energy news on the block this week is the newly designed eere.energy.gov. In case you haven't visited the site lately, the EERE site contains in-depth information about the U.S. Department of Energy's office of Energy Efficiency & Renewable Energy.
Avnet and Tyco Electronics have released a new Pluggable I/O Solutions Sample Kit. The kit includes 15 product samples and four quick reference guides.
A major challenge facing power engineers today is how to overcome a reduction in board space for the power circuitry in commercial electronic products. A quick walk through any electronics retail store will reveal that personal computers have become smaller and even miniaturized which is a trend for many other types of electronic devices.
Medical electronics applications require components that are smaller, more robust, and highly versatile, particularly as medical equipment becomes increasingly portable. Because medical systems often use discrete electronic components in their circuit designs, passive components are critical to optimizing performance and reliability.
