I recently came across an interesting news item in Wired about how the EU was adopting the Universal Charging Solution (UCS) cell-phone power interface. USB has been a kind of power lingua franca for smart phones, but that ubiquitous interface is burdened by a plethora of connector styles.
For several years now, many of the gadgets we use around the house, on the move and in the workplace have contained some form of visual display to impart status information to the user and even allow the user to interact with them via a touch screen.
The do-it-yourself approach to a real-time operating system appeals to many an engineer’s desire to control, schedule, and manage application interrupts. So ten years ago, the number of in-house RTOS applications outstripped all commercial RTOS implementations. Although the do-it-yourself (DIY) RTOS remains the number-one competitor to commercial RTOSs, industry analyst Embedded Market Forecasters has found
The risks to users of wireless technology have increased as the popularity of wireless grows. Hackers are becoming more sophisticated so it's very important that wireless device manufacturers secure their devices properly.
Let’s face it, all of our product design cycles are accelerating. To stay competitive, your company needs the next big thing, they need it yesterday, and it can’t cost any more than it has to if you are going to compete.
Characterizing devices at low current levels requires knowledge, skill, and the right test equipment. Even with all three, achieving accuracy at low current levels can be a challenge because the level of the current is often at or below the noise level of the test setup. To ensure success in low-level current measurements, it is important to know the type of test equipment to use, the different sources of measurement error, and the appropriate techniques to minimize these errors.
VPX is a broadly defined technology utilizing the latest in a variety of switch fabric technologies in 3U and 6U format blades.
Digital signal processors (DSPs) have become ever-present in today’s world, populating everything from stereo systems and cell phones to automobiles and industrial equipment. Despite this proliferation, relatively few embedded developers are DSP-focused.
The feds have just dropped a bomb: The Library of Congress has added exemptions to the Digital Millennium Copyright Act (DMCA) that make “jailbreaking” legal. Apart from fundamentally altering Apple’s business model, the ruling has re-opened the schism between supporters and opponents of digital rights management.
When removed from the comfort of a controlled indoor environment, LCDs can be subjected to a variety of stressful conditions. Extreme temperatures, shock, vibration and variances in ambient light can impact backlight performance and lifetime.
Thermoelectricity has been known since the 1830s. Two functional principles are included under this term: The popular Peltier-Effect describes how electric current flowing through thermoelectric material transports heat, creating a cooling effect.
Hydrogen fuel cells can be used in a wide range of environments such as use in homes, ships, cranes and vehicles. Still, current funding is directed mostly to the transportation sector to be reduce pollution. In this article, we will focus on one of the most exciting uses for fuel cells: a Zero Emission Vehicle (ZEV).
National challenges like the aging power grid, increasing energy demands, spiraling cost of generating electricity and its cost on the environment are all pointing towards the need for a grid that can produce and distribute energy more efficiently and reliably.
The Roundtable question for August is “How much do you feel the current push for “green” tech comes from image and the desire to appear ecologically responsible, and how much does it come from a true pursuit of performance improvement in power systems?”
“Global Warming, Carbon Footprint, and Energy Efficiency” are becoming mantras for the industrial manufacturing sector. With energy costs constantly rising leading to increased overhead costs, the need to use electrical energy in a more efficient manner by reducing the amount is at the fundamental basis of this crisis.
