June 18, 2009[Technology Report] Electronics Helps Foster Decentralized Healthcare
Rising healthcare costs, a stretched-thin number of medical providers, longer life expectancies, and a growing number of elderly and disabled patients are transforming the face of medical care. Decentralization—moving healthcare away from medical facilities and into the patient’s home—is fast becoming the new model. In 2008, Medicaid spending for long-term care cost $99.5 billion, according the U.S. Department of Health and Human Services. ...
June 18, 2009[Technology Report] Auto Electronics Revs Up For "Greener" Pastures
The automobile and electronics industries are struggling mightily through this economic tumult. Straddling these two giants, however, is a shining beacon—auto electronics. At last year’s Convergence Conference, a panel of experts from General Motors, Ford, Chrysler, Honda, and BMW suggested that the cost of electronics in a car will increase beyond the oft-quoted 20% figure and climb to 40% to 50%. Getting more extreme, Honda senior...
April 9, 2009[Technology Report] OLED Displays Bring Much-Needed Light To The End Of The Economic Tunnel
oOrganic light-emitting diode (OLED) technology continues to buck the industry’s current economic struggles, carving out lucrative applications in numerous display and lighting applications. And indications show that active-matrix (AM) OLEDs rather than passive-matrix (PM) OLEDs will eventually dominate this space. DisplaySearch forecasts that OLED display revenues will reach $6 billion by 2015, up from $591 million in 2008, with a compound annual growth rate...
April 9, 2009[Leapfrog: First Look] Alliance Launches Open-Source In-Vehicle Infotainment Development Platform
Leading automobile manufacturers and hardware and software suppliers have formed the Genivi Alliance, a nonprofit organization committed to driving the development and broad adoption of an open-source in-vehicle infotainment (IVI) reference platform (see the figure). The group will unite automotive, consumer electronics, communications, and application development companies investing in the IVI market and...
March 26, 2009[Engineering Feature] CCDs: Performance That Can’t Be Beat
When it comes to high-performance imaging in applications like professional photography, machine-vision inspection, high-definition TV, wireless security, scientific, and military/ aerospace applications, charge-coupled device (CCD) imagers are the only choice. They can deliver sensitivity levels far higher than those offered by CMOS imagers. But then again, comparing CCD with CMOS imagers is like comparing apples to oranges. It all depends on the...
March 26, 2009[Engineering Feature] CMOS And CCD Image Sensor Breakthroughs Promise A "Bright" Future
The latest generation of CMOS and charge-coupled device (CCD) image sensors features wider spectral bandwidths, higher sensitivity levels, lower noise operation, and smaller form factors. Better fabrication processes help lower costs. And, novel architectures are injecting greater flexibility and versatility into circuit designs. As a result, imaging sensors now find homes in mobile phones, notebook and laptop PCs, digital still cameras, video games, toys, medical...
February 26, 2009[Engineering Feature] Those Elusive MEMS Market Figures
Getting a good fix on the market for silicon MEMS microphones is proving elusive, given the declining worldwide economy, the growing number of companies trying to get into this business, and the relatively small size of this market compared to other MEMS devices. On the high side, Yole Développement predicts that silicon MEMS microphones will experience a growth rate of 35% through 2012. Silicon microphones will replace inkjet heads as the largest MEMS product in unit terms, according...
February 26, 2009[Engineering Feature] Sound Check: Silicon MEMS Microphones Ready To Make Lots Of Noise

[Technology Report] Energy Harvesting Looks To Solve Critical TPMS Issues
Ever since Porsche introduced the first direct-type tire-pressure monitoring system (TPMS) in 1997, manufacturers have been struggling to solve two major technical challenges: developing a TPMS that requires as little power as possible to operate (either from a battery or an energy scavenging technique or both) and a form factor that better suits a tire’s shape. On top of that, the need for a low-cost manufacturing approach overshadows both of these issues.
February 12, 2009[Engineering Feature] Making The Healthcare System Technologically Friendlier
People are living longer. More people are living with chronic diseases and disabilities. There’s a shortage of medical providers. And, healthcare insurance premiums continue to skyrocket. Together, these factors cry out for a healthcare system that can serve people better.
