Median income for electrotechnology and information technology professionals jumped by more than 4 percent in 2014, the largest increase in the past five years, according to the 2015 IEEE-USASalary & Benefits Survey.
Median incomes from primary sources — salary, commissions, bonuses and net self-employment income — for U.S. IEEE members working full-time in their primary area of technical competence (job specialty) rose from $124,700 in the 2013 tax year to $130,000 in 2014.
The 4.25 percent increase comes a year after median income rose by its small percentage over the past five years, .56 percent.
The results are based on survey responses from 10,215 people. Here are median incomes since 2009:
Those employed in communications technology once again enjoyed the highest median earnings ($150,000), followed by circuits and devices ($143,008) and signals and applications ($141,062).

The Dell Precision M2800 Mobile Workstation is Available to Help Inspire Innovation for Design Professionals and Students
May 1st, 2014 by Andy Rhodes
The evolution of digital content creation has unleashed the productivity of engineers, designers, creative professionals and students everywhere, but it has also set corresponding expectations incredibly high for that productivity as well, making it crucial for those individuals to use the proper tools to help their visions to come to life. Professional and aspiring engineers and designers cannot do their job these days without specialized applications for 3D modeling, digital content creation, and computer aided engineering and design such as Adobe Creative Cloud and AutoCAD. The problem is, for some, they’re being forced to run these applications on notebooks or desktops that don’t have enough power to generate the performance they need because they can’t afford a traditional workstation.

Indira Negi brings passion for running, biometric experience and maker skills to development of Intel smart earbuds.
When she literally jogged on-stage to join Intel CEO Brian Krzanich in his opening keynote at International CES in Las Vegas, engineer Indira Negi was there to demonstrate the Intel smart earbuds that she and her team had developed, but the “smart” design she showed off also helped solve an issue the avid runner had personally encountered.
“I am a runner — I get hives from the sun, I have to run with gloves on,” said Negi about running with a smartphone. “That means when there is a bad song, I have to take out my phone, take off my gloves, unlock my phone and change the song.”
Starting from solving a problem that she knew all too well, Negi, a sensors systems engineer in the Intel New Devices Group, and a team set out to create a device and software that would monitor heart rate and adjust music playback based on sensor feedback. The result was the Intel smart earbuds reference design, developed in collaboration with Valencell.
Negi’s study of bioelectronics and biosensors in graduate school — she earned a master’s degree in electrical engineering from Arizona State — lent her a keen appreciation of the value of biometric monitoring.
One project she worked on while at ASU measured stress levels in saliva using specially treated paper. When you are working out, you are stressing your body in a positive way, explained Negi. If you work out too hard, this becomes negative stress, which can increase the chances of getting injured. She also worked on molecular imprinted polymers while at ASU coated with biochemical sensors that reacted only to specific molecules.

Design engineers are increasingly spending their time on verification. Research suggests that it is now more than 50% of their time and, according to Harry Foster of Mentor Graphics in his lighter moments, if we continue the current linear trend then it will reach 100% by 2030! So why is verification so demanding? It seems that IP reuse has enabled designers to create larger, more complex designs to keep pace with our manufacturing capability but our verification productivity has not kept pace.
Looking to tools for productivity gains, EDAC (the EDA Consortium) reported that the overall EDA verification market grew by 38% from 2010 to 2012 with emulation up by 94%. But, as Mark Olen of Mentor pointed out “if Henry Ford had asked people what they wanted, they would have said faster horses”. So innovation is also required and Chris Brown of Broadcom set EDA companies the challenge of “collaborative competition” through standards. For example, UCIS has enabled TVS to build an innovative requirements sign off tool (asureSign) by reading verification data from multiple tools.

A new compound developed at Tokyo Tech shows highly unusual conducting properties that could be used in future electronic components. The details are described in the November 2013 issue of Tokyo Institute of Technology Bulletin:
Ordinary insulating solids, such as diamond, have energy bands that are fully occupied by electrons. The conducting band is so far away from the valence band in diamond that electrons do not have sufficient energy to move – the ‘band gap’ is large – therefore no electric current can be carried.
In recent years, researchers have become interested in materials called topological insulators (TIs), which act as insulators on the inside, but are highly conductive on their surfaces. In TIs, an exceptionally strong spin-orbit interaction inverts the energy gap between occupied and empty states, so that electrons at the surface can flow across the gap. These properties are intrinsic to the material, meaning a TI remains conductive even if its surface is not perfect.
Now, an international team of scientists from Japan, the UK and the USA, led by Takao Sasagawa at Tokyo Institute of Technology, have successfully developed a new TI from bismuth, tellurium and chlorine (BiTeCl). Their new TI is inversion asymmetric, meaning it has different electronic states, and therefore different polarities, on each crystal surface. As a result, it exhibits many topological effects that have not been seen experimentally before.
Unravelling the mind-body connection with power-efficient IC chip jointly developed by A*STAR IME, NTU and NUS

Despite the advances in neuroscience research, the human brain remains a complex puzzle with questions unanswered on how it controls human behaviour, cognitive functions and movements. Scientists from A*STAR Institute of Microelectronics (IME), Nanyang Technological University (NTU) and National University of Singapore (NUS) have jointly developed and demonstrated an integrated circuit (IC) chip with record-low power consumption for direct recording of brain activities. This breakthrough minimises the patient’s exposure to electromagnetic radiation and heat during the recording process, making it possible to integrate greater number of channels (>100 channels) to acquire more comprehensive profile of brain signals, paving the way to unlock the mystery behind the complex mind-body connection.
Neural recording system is a vital tool to acquire and process brain signals, and is also applied in artificial limb control (or neural prosthesis) treatments for paralyzed patients. The system comprises multiple electrodes for data acquisition and is implanted within the skull during the operation. The implantability of the system places tight limits on its size and power consumption, while at the same time demanding sufficient performance to record good quality data.
Using Simulation to Optimize Safety, Performance, and Cost Savings When Integrating an Antenna Onto a Platform

Successful integration of an antenna onto a vehicle platform poses many challenges. Vehicle features impact antenna performance by blocking, reflecting or reradiating energy, and co-site interference can impair the effectiveness of multi-antenna configurations. Platform motion and environmental factors such as terrain and buildings may reduce system effectiveness in actual op
The key benefit of simulation-based assessment is that it is relatively fast and cost-effective compared to physical system modification and measurement. The lead times and costs associated with scheduling measurements in an anechoic chamber or at an outdoor test facility sometimes strain schedules and budgets. Modeling and simulation can assess options and tradeoffs in order to select a small number of planned approaches well before any physical testing occurs; as a result, experimental design focuses on verifying planned approaches and fine-tuning alternatives demonstrated to be effective in simulations. This approach reduces the risk of encountering problems that require retesting, costly redesign or introduce dangerous in-theater behavior.
In addition, a number of challenges arise when attempting to perform exhaustive laboratory or field testing on an integrated system. Some potential issues include:
A comprehensive modeling and simulation toolset allows an organization to overcome these challenges by being able to simulate any number of conditions, identify and resolve key issues, and reserve the use of physical measurements to confirm successful pre-test, simulation-based assessments. The remainder of this article provides several examples demonstrating typical simulation-based assessments to identify and resolve issues related to antenna performance and integration onto vehicles.

New production method could enable everything from more efficient computer displays to enhanced biomedical testing.
CAMBRIDGE, Mass. — Quantum dots — tiny particles that emit light in a dazzling array of glowing colors — have the potential for many applications, but have faced a series of hurdles to improved performance. But an MIT team says that it has succeeded in overcoming all these obstacles at once, while earlier efforts have only been able to tackle them one or a few at a time.
Quantum dots — in this case, a specific type called colloidal quantum dots — are tiny particles of semiconductor material that are so small that their properties differ from those of the bulk material: They are governed in part by the laws of quantum mechanics that describe how atoms and subatomic particles behave. When illuminated with ultraviolet light, the dots fluoresce brightly in a range of colors, determined by the sizes of the particles.
First discovered in the 1980s, these materials have been the focus of intense research because of their potential to provide significant advantages in a wide variety of optical applications, but their actual usage has been limited by several factors. Now, research published this week in the journal Nature Materials by MIT chemistry postdoc Ou Chen, Moungi Bawendi, the Lester Wolfe Professor of Chemistry, and several others raises the prospect that these limiting factors can all be overcome.
The new process developed by the MIT team produces quantum dots with four important qualities: uniform sizes and shapes; bright emissions, producing close to 100 percent emission efficiency; a very narrow peak of emissions, meaning that the colors emitted by the particles can be precisely controlled; and an elimination of a tendency to blink on and off, which limited the usefulness of earlier quantum-dot applications.
