Better watch what you say next time you take the bus; somebody could be listening in. We’re all pretty used to the increasing amount of cameras on public transportation, and a lot can be said in their favor. They provide a safer environment for the driver when dealing with unruly passengers.
Electronics manufacturers are constantly looking for ways to improve product quality, speed time to market, and reduce production costs. To optimize manufacturing, engineers carefully consider the three major aspects of production: technology, processes, and materials.
Differential signaling is used for noise immunity in Ethernet, RS-485, CAN and USB. In ideal cases, all common-mode noise is rejected. In real-world applications, there are several design techniques and component parameters to consider in order to keep the data flowing with high confidence.
As the proud new owner of an iPhone 5, I have but one concern: Can this phone survive my clumsy self? For the past three years, I’ve been the increasingly less proud owner of a Blackberry Bold. It was slow, bulky, people mocked me for having it, and viewing a website was as much fun as going to the DMV, but, man, could that thing take a hit like Floyd Mayweather.
Stable platforms are a necessity for achieving the best performance in UAV-mounted surveillance equipment, maritime microwave receivers, vehicle-mounted infrared imaging sensors, and similar instrument systems. Yet these systems must operate through vibration and other undesirable kinds of motion.
Engineers at Agilent Technologies found a need for a digital multimeter (DMM) technicians and electricians could use in cold environments. "I went to college in Canada where temperatures often got down to below -20°C," said Boon Juan Tan, R&D manager in Agilent's Basic Instruments Division.
Sensor fusion is now integrated into most smartphones and tablets, enabling many mobile apps. But consumers want more: they want their mobile devices to be even smarter without having to learn any new interfaces themselves. This article provides an overview of a new class of sensor applications that go beyond sensor fusion....
Device miniaturization is integral to the design and development of a wide range of medical devices, including analytical test equipment, ventilators, and infusion pumps. Making devices smaller and lighter helps conserve valuable real estate in patient rooms, enabling equipment to be placed closer to the patient as well as allowing more space for medical professionals to work.
We’ve all been there. You’re shopping at your favorite store, perhaps running an errand for someone else. But in order to make the purchase, you need to know if it’s right for you. The sales associate is busy helping someone else, or they may be missing in action. You just need the details about the product so you can get it right the first time without having to return it later....
Though Research in Motion (RIM) is banking on the Blackberry 10 release in early 2013 to save the company, Karl Volkman, the Chief Technology Officer of SRV Network, isn’t convinced.“I think it might be too little too late,” Volkman says of the Canadian communications company.
Many of us associated hazardous environments with the oil and gas industries where it is common to see mandatory safety requirements for “intrinsically safe” and “explosion proof” (flame proof) equipment. Other industries including nuclear power generation, chemicals, sub-sea, mining, dusty and high temperature environments also fall within the hazardous environment category.
Josh Norem, an application engineer at Silicon Laboratories, gave me a demonstration of the company's Power Estimator tool available within the larger, free AppBuilder software. The Power Estimator tool now covers the SIM3L1XX Device, although Silicon Labs plans to add sleep-mode power conditions and other MCUs soon.
The path towards higher silicon integration seems inexorable. Already, the suppliers of baseband and applications processors into the mobile-phone and tablet markets are looking at the move to 14nm and 16nm finFET-based processes as they seek further cost savings and performance improvements.
Unmanned underwater vehicles (UUV) and sonobuoys continue to occupy a critical role in undersea warfare, and the design of such technologies – especially with regard to their power systems – is acutely important due to their growing indispensability to a variety of tactical defense operations.
