How to Predict the Progress of Technology

March 7, 2013 10:26 am | by David L. Chandler, MIT News Office | Comments

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.

Improving Performance and Power with Sensor Hubs

March 1, 2013 1:36 pm | by Bryon Moyer, Convergence Promotions LLC | Comments

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: Less is more for 2013

March 1, 2013 9:21 am | by Bryon Moyer, Mouser Electronics | Comments

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.

Teaching Robots Lateral Thinking

February 26, 2013 9:42 am | by Larry Hardesty, MIT News Office | Comments

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.

Why do Satellites Fail?

February 26, 2013 9:19 am | by Simon Firth, Stanford Engineering | Comments

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.

Addressing Bandwidth Challenges with LTE and MIMO

February 20, 2013 3:21 pm | by Stephen Turnbull, Senior Wireless Solutions Product Manager, Freescale Semiconductor | Comments

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.

Brainstorm: Wireless Power

February 19, 2013 4:39 pm | by WDD Staff | Comments

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.

Turning Ideas Into Validated Products—Faster

February 15, 2013 4:46 pm | by Andy Botka, Agilent Technologies | Comments

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.

What is the Real Smart Home?

February 15, 2013 3:52 pm | by Elly Schiatse, General Manager, GreenPeak Belgium | Comments

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.

Wireless Communication Systems Using Phased Array Antennas

February 14, 2013 3:31 pm | by Dr. John Howard, President & CEO of Electromagnetic Technologies Industries, Inc. (ETI) | Comments

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...

Monetizing LTE Investments: Dynamic Policy Management

February 14, 2013 11:37 am | by Graham Kunz, Product Marketing Manager, Empirix | Comments

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.

Transmitter Measurements on Multistandard Base Stations

February 12, 2013 2:11 pm | by Martin Schmähling, Spectrum Analysis Product Manager, Rohde & Schwarz | Comments

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.

Components, Characteristics and Device Implementation

February 12, 2013 10:24 am | by Luis Puebla, Applications Engineer, Freescale | Comments

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.

Proper Data Security

February 12, 2013 9:37 am | by Dean Wiech, Managing Director at Tools4ever | Comments

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.
