News Focus ********************** Walking Yields Wattage Researchers have found yet another benefit of walking -- it can be used to generate power for portable electronics. A new backpack can generate electricity by harnessing the mechanical energy created by walking. The walker's up-and-down hip motion makes the backpack's suspended load bounce up and down, generating up to 7.4 W. A typical cell phone consumes roughly 1 W. A team of biologists at the University of Pennsylvania developed the backpack's generator with funding from the U.S. Office of Naval Research. The original goal was to eliminate the need for soldiers to carry weighty spare batteries to power critical equipment such as communication devices and night-vision goggles. However, the developers hope the backpack also will be useful to field scientists, explorers, and disaster relief workers in remote locations. A sack carrying the load is suspended from the backpack's rigid frame by vertically oriented springs. Normal forward walking causes the hip, and the backpack load, to move up and down by 5 to 7 cm with each step. The vertical movement of the backpack contents provides the mechanical energy to drive a small generator mounted on the frame, creating a current that can either run a portable device or charge a battery ( view video of backpack operation at http://nls.planetee.com/t?ctl=137F4:1001CD ). Prototype testing showed that the backpack's power output increased with walking speed and with the weight of the load in the pack. University of Pennsylvania researcher Larry Rome has set up a company called Lightning Packs to commercialize the idea.

A large display and GUI bring confidence that what you set is what you'll get. Be the first to see what the next generation signal generators can do for you. http://nls.planetee.com/t?ctl=137F5:1001CD **************************************************************** ********************** 2. News -- From The Editors ********************** ***Semiconductor Sales Growth Will Hit Low Point In 2005 The rapid rise in global energy prices and a growing excess of manufacturing capacity have prompted market researcher iSuppli to trim its forecast for 2005 semiconductor sales and to modify its outlook for the industry's present growth cycle. While it's still not clear what impact Hurricane Katrina will have on the semiconductor industry, iSuppli believes that at the very least the catastrophe will exacerbate the market's energy problems in the short term. The company's previous forecast was for 5.9% worldwide semiconductor growth in 2005. However, it now predicts that global semiconductor sales will rise to $232.7 billion in 2005, up only 2.4% from 2004. It also predicts that 2005 will mark the low point of the present semiconductor cycle and that growth will accelerate during the following years. After a marginal rise in 2006, chip sales are expected to rise by double-digit percentages in 2007, 2008, and 2009. iSuppli Corp. ==> http://nls.planetee.com/t?ctl=137FF:1001CD ***Splayed Pins Sink More Heat Cool Innovations claims its splayed-pin fin heatsinks generate 20% to 30% better cooling than standard-pin fin heatsinks when operating in low-airspeed environments and in the natural convection mode. UltraCool P pin fins feature an array of round pins that are splayed outwards. They possess the same large surface area of conventional pin fin heatsinks but aren't as densely configured. The sparse configuration enables surrounding airflows to enter and exit the pin array more efficiently. UltraCool P pin fin heatsinks are forged from pure aluminum and oxygen-free copper. They're available in a wide variety of standard sizes, ranging in footprint from 0.5 by 0.5 in. to 2.0 by 2.0 in. and in height from 0.2 to 1.1 in. The new splayed line suits any surface-mount package type and is offered with pre-applied double-sided thermal tape or mechanical clips. Pricing begins at $1.50 each. Cool Innovations Inc. ==> http://nls.planetee.com/t?ctl=137FE:1001CD ***CMOS Sensors Bring High-Res To The Mainstream A pair of CMOS sensors brings high-quality images to mainstream image-capture applications such as digital cameras and camera phones. Both the 5- and 3.1-Mpixel image sensors are equipped with Micron Technology's proprietary low-noise, high-sensitivity DigitalClarity technology, which helps output high-quality images while also extending a device's battery life. The 5-Mpixel MT9P001 sensor is designed for either digital camera or camera phone applications, while the 3.1-Mpixel MT9T012 sensor just targets camera phones. The sensors were developed using a pixel size of 2.2 microns square, which created a small form factor to accommodate shrinking camera and camera phone size while preserving picture quality. In addition, both sensors feature pixel binning, simplified mechanical shutter support, and support for multiple interface standards. The 3.1-Mpixel image sensor is currently sampling, with production quantities available in the fourth quarter. Samples of the 5-Mpixel image sensor are expected to be available in November.

TechView Scope ********************** Apple Taps Flash Memory For Latest iPod Apple has done it again. The iPod nano offers 2 or 4 Gbytes of flash memory, based on the model, starting at $199. That's 500 or 1000 songs, respectively. Measuring just 3.5 by 1.6 by 0.27 in., this 1.5-oz device is about as thick as a pencil. But it still features a 1.5-in. color LCD and the click wheel that iPod fans have grown to love. Its built-in rechargeable lithium-ion battery offers up to 14 hours of music -- or, four hours of slideshows with music. The player also holds up to 25,000 photos. Users on the go can sync their iPod nanos with their calendars, contact lists, and to-do lists. And, it comes in white or black. The iPod nano works with Mac OS X and Windows 2000/XP.
