Low-Power Logic Gate Protects Fluid Sensor From Leakage Current
Fluid-level sensing is very common in industrial applications and now is being used in domestic applications to sense water levels in overhead tanks. The greatest challenge for designers is to make these sensors operate with ultra-low power using battery voltages between 2 and 6 V, while making the device insensitive to potential damage from leakage current coming from mains power running pumps and valves. The design described here uses three sections of a...

DC Blowers Provide Directional Cooling In Tight Spaces
Measuring 120 by 120 by 32 mm and 97 by 94 by 33 mm, respectively, the ODB600PT and ODB9733 dc blowers from Orion Fans suit use in space-constrained applications like fuel cells in hybrid vehicles, telecom equipment, and other powered products that require thermal management. According to the company, these low-profile blowers provide directional cooling similar to spot coolers in a flat, compact design.

Mature Display Technology Still Viable In Advancing Markets
When we think of displays these days, the first technologies that come to mind are LCDs, LEDs and organic LEDs (OLEDs), and touchscreens. These components, though not new, proliferate and evolve because of a number of factors. Constant research and development in the electrical, mechanical, and chemical/materials disciplines uncovers ways to make these displays cheaper, more functional and energy efficient, and easier to integrate into new...

Future-Proof Low-Profile 1U And 2U Systems With High-Speed Connectors
Choosing connectors that meet increased speed and density requirements for low-profile 1U and 2U rack-mountable systems is a complex task. Increases in signal-pin counts and power consumption have turned system packaging design for optimal airflow into an increasingly difficult challenge. Common to network interfaces, storage, and telecom equipment, these lowprofile systems require long-lasting connector configurations that can...

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...

Sound Check: Silicon MEMS Microphones Ready To Make Lots Of Noise
What’s that rumbling? It’s the ever-loudening boom expected to stand the silicon microelectromechanical systems (MEMS) microphone market on its collective ears. Forecasters say the market explosion will really unfold after 2009. Two years ago, only three or four dominant silicon MEMS microphone manufacturers existed. Knowles Acoustics had the lion’s share, followed by Akustica, Pulse Engineering’s Sonion MEMS Division, and Infineon Technologies. Now the list...

Low-Loss Chokes Serve Inverters In Railway Applications
For use in drive control, power electronics, power generation, wind power and photovoltaic installation as well as instrumentation and control, SMP supplies chokes and filters for frequencies up to 200 kHz and current ratings up to 1 kA. Depending on their application, the inductive components are constructed either as single-conductor chokes for high-current applications, individual chokes, choke modules, or LC filters.

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.

Whatever Happened To Heathkit?
Whenever I mention to folks that I used to work at Heathkit, a few people actually ask, “What’s Heathkit?” Yes, I suppose that does date me a bit. Others will say, “Oh, yes, my dad used to build Heathkits.” Anyway, some of you do remember Heathkit, and fondly in most cases. And believe it or not, it's still around.

Ultra-Low-Power, Ultra-Low-Noise ASIC Breakthroughs Enable New MEMS Sensors
Often, a technological breakthrough can lead to new products and even new applications that had previously been considered fantasy. Developments in low-power, low-noise readout ASICs could open new opportunities for microelectromechanical-systems (MEMS) sensors, particularly in medical monitoring, implantable devices, and military/sports monitoring.

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. But while the tools for diagnostics and healthcare treatment rapidly advance in performance, no practical system exists for their mass-scale adoption. A lack of standardization among healthcare device inputs...

The Pulse Quickens For Cutting-Edge Medical Electronics Advances
Picture this: A heart patient is experiencing fluid buildup in the lungs—an early sign of heart failure. But, an implantable sensory medical device in the patient emits a signal to both the patient and his physician via a Bluetooth-equipped mobile phone, warning them of impending danger. Wishful thinking? Not really. The technology is already here and is continuously being refined. All that’s missing is the supporting infrastructure. Mir Imran, an inventor and...
