For some University of Colorado Boulder undergraduates, designing, building and flying small satellites is becoming a large part of their hands-on education. NASA recently selected CU-Boulder as one of 24 institutions or organizations to fly tiny satellites as auxiliary payloads aboard rockets planned for launch in 2014, 2015, and 2016.
When Charles Babbage prototyped the first computing machine in the 19th century, he imagined using mechanical gears and latches to control information. ENIAC, the first modern computer developed in the 1940s, used vacuum tubes and electricity.
Mobility continues to be the hottest trend for the semiconductor and electronics industry. As though there were any need for supporting data, the major electronics shows from the first quarter of 2013 displayed and demoed the latest array of mobile devices.
Amidst the much-discussed love affair between consumers and their mobile devices, another relationship is blooming in the mobile sector. Device manufacturers from nearly every vertical industry are increasingly offering devices and products equipped with mobile connectivity, transforming “dumb” devices into “smart” ones.
There's no question that LTE is where it's at if you're an operator. According to a recent report from 4G Americas, more than 150 operators globally have now launched LTE services in 67 countries, 50 of which were launched in the past five months.
Researchers at MIT and the Santa Fe Institute have found that some widely used formulas for predicting how rapidly technology will advance — notably, Moore’s Law and Wright’s Law — offer superior approximations of the pace of technological progress.
Sensors have become a regular feature in many systems. They reside alongside numerous other peripherals to add to the range of environmental inputs that can be incorporated into the job being done by the system. However, in some systems, the number of sensors threatens to overwhelm the other more traditional peripherals.
Power has come of age as a defining parameter in electronic systems. Whether maximizing battery life, keeping an enclosure cool, or passing large currents more efficiently, projects now start with power in mind. In 2013 we will see the continued migration of power technologies from research to commercial availability.
Many commercial robotic arms perform what roboticists call “pick and place” tasks: The arm picks up an object in one location and places it in another. Usually, the objects — say, automobile components along an assembly line — are positioned so that the arm can easily grasp them; the appendage that does the grasping may even be tailored to the objects’ shape.
In the popular imagination, satellites are imperiled by impacts from ‘space junk’ – particles of man-made debris the size of a pea (or greater) that litter the Earth’s upper atmosphere – or by large meteoroids like the one that exploded spectacularly over Chelyabinsk, Russia last week.
The sheer number of smart connected devices with data-intensive applications, such as high-definition video, has created an explosion in the demand for mobile broadband. This trend increasingly requires wireless infrastructure equipment manufacturers and wireless service providers to dramatically boost network performance.
As our smart phones, tablets, and other wireless devices get smaller and smaller, this creates more challenges for the electronic designer. And as we depend more on these devices, and give up our paper calendars, note pads, and other old fashioned ways of keeping track of our lives.
For test equipment manufacturers and their customers, one trend is unavoidable: the deepening integration of the RF, microwave and high-speed digital technologies used inside today’s electronic systems, especially mobile devices. To satisfy end-user demand for always-on access and fast data rates, mobile devices need powerful processing capabilities.
You are ready and packed to leave on a holiday trip and for the first time, you agreed that your teenage son can stay home alone. The control freak in you is already making long lists of daily and weekly tasks and to-do’s to keep the pets and plants alive, and the calamity predictor in you wants to anticipate for flooded bathrooms and burning fryers.
There are many factors that contribute to the limitations of wireless systems, of which arguably the most important are frequency bandwidth (spectrum availability) and frequency efficiency. Though efficiency may be increased by higher modulation rates, more sensitive receivers and more accurate bit error detection/correction methods...
