Mechanisms like lockstep CPUs, error correction code (ECC) logic for embedded memories and automated built-in self test (BIST) engines integrated into embedded controllers may greatly simplify and reduce the development time needed to design and certify safety critical electronic systems for the aerospace industry.
In early January 2013, the CBC News concluded its investigation about Canada’s new Hercules C-130J aircraft military transport aircraft containing counterfeit Chinese parts in the cockpit instrumentation. The report confirms what a leading U.S. testing lab has known since 2010 — that the parts are fake and could leave pilots with blank instrument panels in mid-flight.
For anyone designing, manufacturing, or repairing electronic equipment, a digital storage oscilloscope is a must-have tool. It lets you see high-speed repetitive or single-shot signals across multiple channels to capture elusive glitches or transient events. An oscilloscope is equally as useful a tool for qualifying elements of a new design....
Since the very early days of electronic components, failures have continuously been appearing. In spite of enormous development and production improvements, this situation has not changed. The increasing circuit density and board complexity are critical factors for producing faults.
Driven by financial gain and opportunism, counterfeiting is not new, or uncommon. Recently, counterfeited products have been appearing in the military and aeronautics marketplace as counterfeiters take advantage of profitable components. PD&D caught up with Mark Bollinger, Vice President of Marketing at Smith & Associates, to learn more about this trend....
As technology has become more pervasive in our day-to-day lives, easy adoption is a critical factor in the overall success of a product release. To achieve this, embedded designers must first determine the practical problem the application will solve or the tangible life enhancement it will offer.
How do you test and debug a device with hundreds of thousands of internal logic cells and transceiver speeds up to 28 Gbps? Such is the challenge facing designers of today’s industry leading FPGAs. From the perspective of digital debug, the biggest challenges arise from the inaccessibility of critical logic nodes and a limitation on the number of available physical pins.
Designers of energy-efficient, high-speed memory subsystems for small form factor or power-sensitive embedded and wireless products are often making the shift from traditional DDR2/DDR3 to low power (LP) DDR2/DDR3 memory solutions. This is largely in response to the ever-challenging power reduction requirements....
Users want ever-smaller and lighter devices but also demand ever-increasing storage capacity to keep more apps and data loaded on their mobile computing platforms. To accommodate these two competing objectives, solid-state storage form factors will need to get smaller, while NAND flash memory geometries will be shrinking and storing more bits per cell.
On 14 September 1993, Lufthansa Flight 2904 overran a runway in Warsaw because the reverse thrust deployment system operated exactly to specification. Unfortunately, the Airbus designers had not anticipated conditions during a cross-wind landing. In an analogous incident, on 11 July 2011, a Victoria underground train in London moved off with the doors open....
While writing my February 2013 column about EDRs (event data recorders, AKA “black boxes”), I came across an article on the same topic (http://bit.ly/12YX4Fe) by one of my colleagues. She commented on the reservations I share with many others about the use of the data derived from the black boxes.
The rapid pace of technological change means that, even before a system has matured, it often is replaced or enhanced with new technologies. Such is the case with machine-to-machine (M2M) applications and their migration to the cloud, or what sometimes is called the Internet of Things (IoT).
The automotive sector continues to research ways of saving on traditional fuel and expanding alternatives. However, this change has not really moved forward due to the cost-prohibitive nature of new technology. Some of the most commonly discussed alternatives are battery-powered cars, namely electric vehicles, hybrid electric vehicles, and fuel cell vehicles.
Since when did waggling a joystick become more valorous than pulling a trigger? It hasn’t, you say? The newly-minted Distinguished Warfare Medal — created to honor cyberwarriors and drone pilots — would rank above the Bronze Star and Purple Heart, and the military community is incensed.
Q: What role will sensors and controls play in emerging solid state lighting applications? Solid-state lighting technology is a natural fit in our digital, wireless world. Adaptive control and wireless sensor networks are the key to ever more sophisticated LED lighting schemes including dimming,
