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...
LTE is no longer the future of telecommunications; it is now a key component of the network’s infrastructure. Service providers are investing heavily in this technology to meet customer demand as consumers continue to purchase smart phones, tablets and other wireless devices at unprecedented rates.
Following its introduction 20 years ago, GSM has established itself as the de facto global standard for mobile telephony. Since this time, wireless communications has continued to develop. Whereas GSM was initially only designed for voice, the GPRS and EDGE extensions have also made it usable for data services.
According to the National Sleep Foundation, more than 18 million American adults have obstructive sleep apnea (OSA). OSA occurs when the back muscles of the throat relax while sleeping, causing the airway to narrow, resulting in snoring. These muscles could also completely block the flow of air to the lungs.
There are really three sides to proper data security. The first step is ensuring that new employee accounts are created with the proper access rights when an employee joins the organization. The second is making sure those access rights remain accurate during the employee’s tenure, and the third is revoking all access rights when the employee leaves.
The “TD” (Time Domain) flavor of LTE can no longer be viewed as a niche technology exclusive to China. Other countries worldwide, including India and Sweden, are embracing TD-LTE for their broadband wireless access rollouts. Before long, close to half the world’s population will be within reach of a TD-LTE network. India will have a full commercial service ahead of its northern neighbour, China.
The byproducts of Moore’s law have increased the performance and reduced the cost of electronic products across every industry for more than half a century. The development pace and proliferation of mobile devices today have leveraged Moore’s law, growing at a projected 24.9% CAGR for 2011 – 2017 (ovum.com, May 3, 2012).
The next advance in weather forecasting may not come from a new satellite or supercomputer, but from a device in your pocket. University of Washington atmospheric scientists are using pressure sensors included in the newest smartphones to develop better weather forecasting techniques.
