Editor's View -- Exclusive to Electronic Design UPDATE ********************** MEMS Accelerometers Set To Invade Consumer And Medical Electronics By Roger Allan, Contributing Editor For the last several years, MEMS accelerometers have been making themselves present in many automotive applications, primarily for triggering airbags during crashes. Most of these sensors have been two-axis models, sensing motion in the x and y axes, and they have commanded prices too high for consumer electronics and computer gadgets. Within the last few months, however, lower cost and higher performance have changed that. Tri-axis MEMS accelerometer sensors that can sense more sophisticated functions in the x, y, and z axes are now widely available. They sense more complex and subtle 3D movements. Also, they cost $2 to $5 each, which is an attractive price for a wide variety of consumer electronics applications as well as some medical electronics uses. Freescale Semiconductor inspired this trend three months ago with a product that provides inexpensive low-g sensing for portable handheld consumer electronics (see "Accelerometer Offers Economical Low-G Sensing" at http://www.elecdesign.com , ED Online 10221). Many other sensor manufacturers have thrown their hats into this market, including Analog Devices, STMicroelectronics, Hitachi Metals, Kionix, and Oki Electric. The most recent entry is Bosch's Sensortec, which announced a product this month. EmTech Research sees this market expanding from last year's sales of 48 million units to about 52 million units by 2009. While this level doesn't match the growth of other types of semiconductor ICs, the new lower-cost and more capable accelerometers may yet create the market conditions needed for an even broader application of these devices. If that happens, prices might drop down to about $1 per axis of sensing. Current applications include protecting hard drives in computers and cell phones from data loss due to shock from rapid movement or a fall. They're also being used in audio and video recorders and players, PDAs, gaming controllers, MP3 players, inclinometers, and more. Beyond the benefits of hard-drive data protection, tri-axis MEMS accelerometers may serve in a number of yet-to-come user interfaces for consumer electronics. For example, a user might be able to "tilt" a PDA and have it scroll through a list of contacts. Cell-phone users may be able to use gesture recognition like issuing a command quickly, for instance inside a theater, to turn off the cell phone without having to touch the phone at all. Samsung Electronics already markets a cell phone for the Asian market, the SCH-310, that responds to several complex movements. It recognizes numbers that users dial in the air. Shaking the phone twice deletes a message or ends a call. And by giving the phone a sharp flick to the left or the right, users can make its MP3 player skip tracks backward or forward. Beyond this lie applications like GPS enhancement for navigation inside tunnels when the satellite signal is not available and compass-tilt correction. Even more promising are medical electronics applications like metered drug delivery, drug bio-analysis, and health and recreational devices like pedometers. **************************************************************** ********************** 2. Focus On DSP ********************** ***Ultra-Thin DSP Caters To Mobile Wireless Apps Aimed squarely at the Voice over Wi-Fi (VoWiFi) market, the LSI403US digital signal processor from the DSP Products Division of LSI Logic is a natural for dual-mode handsets. It delivers the appropriate mix of performance and small footprint needed for cell phones, PDAs, and other handheld wireless devices. The 16-bit, fixed-point DSP is based on the company's low-power LSI403LC processor. As a result, it draws very little power per voice or audio channel. Other features include dual time-dvision multiplexing ports for audio analog-to-digital converters/digital-to-analog converters, 48 kwords of on-chip RAM, and two on-board 16-bit timers. The processor also sports high-bandwidth interfaces for additional wireless devices, such as wireless local-area network and Bluetooth products. The Z.Voice software library provides industry-standard Voice over Internet Protocol algorithms. The LSI403US comes in an ultra-thin LBGA package that measures 7 by 7 mm. It's available now for less than $4.00 in 100,000-piece quantities. DSP Products Division of LSI Logic ==> http://nls.planetee.com/t?ctl=11517:1001CD ********************** 3. News -- From The Editors ********************** ***Build-to-Spec Linux Targets Roll-Your-Own Developers While having control over one's development tools and platform may have long-term benefits, building and configuring a Linux platform isn't easy. TimeSys now has Built-to-Spec Custom Linux Distributions for embedded developers using Linux in device designs based on PowerPC, Intel XScale/IA-32, MIPS, and ARM architectures. Using the Timesys customization Web site, developers pick and choose the platform and other specifications they need. Then, Timesys delivers a custom version of Linux for a particular processor and board configuration. Developers get back a custom, cross-development tool chain, a prebuilt target root file system, a Linux kernel, and a 14-day evaluation version of the Eclipse 3.0-based Timestorm Linux development suite. The package comes with source for all of the Linux components. It provides developers with a quick and efficient way of getting started with Linux. Pricing starts at $499.

EFAB Access is a prototyping service offered by MOSIS for MEMS and microdevice development that includes Microfabrica's 3D micromanufacturing technology. The three winning microdevice designs will be built for free. In addition, the top three contestants will receive MEMS-related prizes: a Segway i180 (first place), a Segway p133 (second place), and a Toshiba TDP-T90U DPL projector (third place). The competition is open to all individuals who have a commercial or research interest in microdevices, and there's no limit to the number of entries that can be submitted. Entries must be submitted by November 11, 2005. Winners will be announced in January 2006. Visit the competition's Web site for more information and full contest rules. EFAB Access Design Competition ==> http://nls.planetee.com/t?ctl=11519:1001CD ***CCFL Inverters Resist Moisture, Shock, And Vibration Harsh environments don't have a chance against a family of dc-ac inverters designed for powering CCFL-backlit (cold cathode fluorescent lamp) LCDs. The E200II and SE/SE2 series inverters from ERG employ a vacuum-encapsulated design to ensure reliable CCFL ignition despite moisture, shock, or vibration. ERG's inverters operate at high efficiencies, typically 80 percent to 85 percent, and are designed and tested using the actual LCD assembly to ensure system compatibility. All magnetics are self-shielding to minimize electromagnetic and radio-frequency interference. The company offers standard units for a range of displays and applications. The E200II can power one or two CCFLs with up to 8 W of output power, while the low-profile SE/SE2 series provides up to 5 W of output power for one or two CCFLs. Pricing for the E200II and SE/SE2 series dc-ac inverters starts at $8.55 in production quantities. Delivery is four weeks ARO.

Electronic Design Helpline ********************** ***Rotation Sensing An Electronic Design reader asks: "I have a data logger that works from 0 to 5 V dc that I'm using in a race-car application. I want to be able to convert ground distance to a 0- to 5-V dc scale. I can create any hardware needed for this application. I was thinking in terms of having a wheel on the ground and a sensor or trigger that will step voltage from 0 to 5 V. I can calibrate it to find that x voltage is equal to y feet, for example. Would an optical sensor work? I want to record a distance of 0 to about 350 ft. It would also be great to be able to get a speed out of this (0 to about 30 mph). I have a time frame on the logger, so I guess I could calculate speed from that." Do you have any tips, ideas, or resources to offer?
