The morning of December 4, 2011 began normally for the team of Air Force technicians. As they settled into their shift flying unmanned aircraft over Afghanistan, perhaps they chatted casually and swapped stories from the weekend. Very soon, however, their conversations were interrupted by shrill alarm sirens blaring from their control monitors.
There's a "back to the future" aspect to power distribution for datacenters in the 21st century. At the beginning of the 20th century, Thomas Edison was a proponent of distributing power to homes and businesses using higher-voltage DC, while Nikola Tesla’s backer George Westinghouse supported distribution via AC.
There is a saying that you cannot teach an old dog new tricks. While CAN is 25 years old, it continues to grow and gain new capabilities. It has been adapted into widely varying applications starting with its roots in simple automotive multiplexing to the current automotive networks, transportation, and industrial applications.
Over the years, the relative stability of the defense and aerospace industry has served as a stable and reliable revenue pool. This market has attracted a variety of manufacturers to help offset the cyclical changes in the commercial and industrial markets. Aerospace and defense (A&D) companies continuously search for the latest and best commercial technologies...
Electromechanical components are not all created equal. A primary concern for design engineers when specifying electromechanical components in industrial applications is ensuring the products are rugged and robust enough to withstand harsh industrial environments.
The information stored within datacenters has become the foundation on which many organizations today conduct daily business and operations, and in many cases, is considered to be their most valuable asset. From the facility down to the cabinet level, security is a key concern of datacenter engineers.
Meeting satellite design challenges with both off-the-shelf and customized space-grade DC-to-DC converter solutionsSeptember 11, 2012 9:30 am | by Rob Warren, Vice President and General Manager, Microsemi Corporation | Articles | Comments
Satellite design engineers face many difficult issues. End customers such as the U.S. Air Force are demanding ever higher levels of reliability. Failure in space-related applications is not an option. The products used in satellites must work every time, in a plethora of environmental extremes...
Over the past 150 years or so, the lighting industry has evolved into a mass production industry built around the concept of standardized bulbs, designed with built-in obsolescence. Consumers find themselves frequently replacing identical, short-lived products with more of the same. This trend is supported by a small number of large manufacturers that meet demand by building billions of identical products at low cost.
A fundamental aspect of any capacitive sensing design is the calibration of the sensor. Calibration eliminates the sensor providing false actives in the system and as well as the sensor failing when it is supposed to be active. Until recently, individual sensor also had to be accompanied by discrete components comprised of resistors and capacitors in order to adjust the sensitivity of each particular sensor.
Smart lighting control technology is being used in more and more consumer applications to allow control of light intensity, hue, and saturation. With the number of competing light control systems on the market, the user interface is often the major differiator between systems and determines the success or failure of a consumer product.
Evolving user expectations are placing increasingly high cost and performance pressures on industrial manufacturers. Real-time performance has always been an important aspect of industrial designs, and increasingly, industrial designs are using sensors to monitor real-world signals such as temperature, pressure, flow, sound, and position.
If you’re not designing Wi-Fi (802.11) into your systems already, you’ll be doing so very soon. Wi-Fi is rapidly establishing itself as the standard wireless connection for industrial devices. It’s a big change, but it needn’t be intimidating. There are plenty of vendors out there who have all of the necessary expertise.
Industrial applications cover a broad range of solution types. Depending on whom you ask, the industrial market segment can include military, scientific and commercial solutions. Though these segments run across a broad spectrum, there are some common themes that a design team must confront regardless of which area their particular application is focused on.
LED-based streetlights first appeared on streets about four years ago, mainly as design concepts or test lamps at universities. Yellow phosphor was one of the only available and stable phosphor at that time with the ability to create white light in conjunction with a blue chip.
Renewable power generation technologies based on solar and wind are usually discussed in terms of photovoltaic arrays and very large land- and sea-based turbines. Behind these very visible physical structures that can encompass many acres sit the optoelectronic components that provide the galvanic isolation...
There is no question that among the most popular and more affordable hand-held electronic devices to hit the market in recent years are e-readers based on e-paper. They go by various names and several brands (Nook, Kindle, Sony, etc) but they all function in the same manner.
A wide range of devices are designed to handle, convey and store sensitive information that require varying degrees of security from protecting low level administrative to classified and top secret information. In addition, the information and data can reside in an equally wide range of locations and environments...
Measuring stored energy in an electrochemical device, such as a battery, is complex and state-of-charge (SoC) readings on a fuel gauge provide only a rough estimate.Users often compare battery SoC with the fuel gauge of a vehicle.
Temperature, humidity and other physical measurements in digital instrumentation typically utilize successive approximation (SA) analog-to-digital conversion (ADC) techniques to acquire data.
Today's flat-panel TV sets have bright, detailed pictures. They look great even when not operating, as a result of thin profiles and disappearing bezels. And, they connect so easily to the Internet, Skype, and BluRay players...
High-tech risk management: Sophisticated inspection procedures & equipment for counterfeit detectionMarch 14, 2012 5:34 am | by Robert W. Chesla, Senior Project Engineer, Rockwell Automation & Nora Gibbs, Account Executive, Smith & Associates | Articles | Comments
A successful and effective anti-counterfeiting strategy must be implemented when an end-product manufacturer purchases components from an independent distributor.
Sophisticated battery-operated electronic systems and self-powered devices recently have found diverse applications in existing autonomous and handheld objects. Significant advancements in CMOS process technologies and circuit techniques...
In small home appliances such as microwave ovens, coffer brewing systems, rice cookers and induction cookers, there has been a growing demand for capacitive sensing interfaces. These interfaces, typically buttons and sliders, can help differentiate a product...
Lithium-ion batteries are expensive to manufacture and this is mainly due tothe high raw material cost and complex preparation processes. The most costly metal of most Li-ion is cobalt, a hard lustrous gray material that’s also used to manufacture magnets and high-strength alloys.
Designers of networking and communications equipment can feel the Earth moving beneath their feet. These dramatic changes have been caused by the increasing need to process traffic as stateful flows instead of individual packets.
