News Focus ********************** UWB Technology Increases Security In Wireless Networks Sandia National Laboratories, in cooperation with Time Domain Corp. and KoolSpan Inc., has developed a secure wireless ultra-wideband (UWB) data-communication network that's used to help sensors monitor U.S. Air Force bases and Department of Energy (DOE) nuclear facilities. It also aids in wireless control of remotely operated weapon systems. The Sandia project is considered a milestone for the next generation of secure wireless networks. UWB technology, also known as "impulse radio," is different from other forms of RF communication because it does not use a carrier. Instead, UWB transmits a flood of ultra-short microwave energy pulses (about 100 ps in duration) that extend over an extremely wide band of energy covering several gigahertz. Sandia's secure wireless communication combines UWB technology with heavy-duty protection from the 256-bit Advanced Encryption Standard (AES) to form UWB/AES. UWB signals provide secrecy for covert operation by hiding near or within the noise floor to prevent detection. It's particularly difficult for other forms of RF communication to operate in that undetectable region. UWB's probability of survival increases in a toxic RF battlefield when compared to many other forms of RF. The UWB/AES network architecture requires no computing infrastructure, provides real-time (hardware) encryption, and requires zero maintenance for complete self-recovery if interrupted or if a sensor goes down. Tests conducted at the KoolSpan Encryption Laboratory in Santa Clara, Calif., demonstrated a wireless UWB network bridge with real-time 256-bit AES encryption for live-streaming video images. The tests used only microwatts of transmitted power -- approximately 1000 times less power than what's typically used by conventional wireless IEEE 802.11b or Wi-Fi networks.

News -- From The Editors ********************** ***Flexible Laminate Responds To Touch Designers can build a touch interface on nearly any surface using Interactive Surface Technology (IST) from 3M Touch Systems. The MicroTouch IST touch interface is constructed of a flexible, polyester layer that can be laminated to any surface, including contoured objects. The substrate for lamination can be plexiglass, polycarbonate, or any other nonconductive material. MicroTouch IST supports "on display" use with LCD panels or "off display" use creating touch pads or button interfaces without a display. Products used in outdoor environments can employ laminated stack-ups integrated with Vikuiti solar-reflecting film for heat resistance or Vikuiti light-control film for privacy. An optional protective, replaceable front surface for a MicroTouch IST touch screen is planned for future release. 3M Touch Systems Inc. ==> http://nls.planetee.com/t?ctl=FF9C:1001CD ***Global Semiconductor Sales Up In First Half Although worldwide sales of semiconductors declined slightly in the second quarter, the Semiconductor Industry Association (SIA) reports that total sales were up in the first half of 2005. For the first six months of the year, global chip sales totaled $109.0 billion, an increase of 6.5 percent over the first six months of 2004. Sales in the second quarter of 2005 came in at $53.9 billion, a sequential decline of 2.1 percent from the first quarter. The SIA predicts that the strongest growth in 2005 will occur in the second half of the year. Most major end markets for semiconductors, including PCs and wireless handsets, saw unit sales substantially above expectations in the second quarter. Semiconductor manufacturing utilization rose after two quarters of sequential decline, and recent reports indicate utilization rates will continue to increase in the third quarter. Semiconductor Industry Association ==> http://nls.planetee.com/t?ctl=FF9B:1001CD ***Tiny Battery Chargers Inhabit 2-mm Package The LTC4065 and LTC4065A tiny, standalone linear battery chargers can charge a single-cell lithium-ion battery wih a charge current up to 750 mA without overheating the device or surrounding components. A patented thermal regulation scheme prevents the junction temperature of the charger IC from exceeding 115 deg.C by reducing charge current during high power or high ambient-temperature operation. Both ICs offer timer termination, recharge, trickle charge, and C/10 detection. They're housed in a miniature six-lead, 2- by 2-mm DFN package. A complete charging system needs only two additional discrete components -- an input capacitor and a charge-current program resistor -- and fits into a 2.5- by 2.7- by 0.75-mm form factor. Applications include digital still cameras, portable diagnostic equipment, cell phones, PDAs, and USB-equipped handheld devices. Pricing starts at $1.40 and $1.55 each in 1000-piece quantities.

TechView Scope ********************** Student Teams Compete For EPA Prize And Greener Tomorrow It's never too early to start thinking about the future. That was the mission behind the Environmental Protection Agency's first annual P3 Awards -- People, Prosperity, and the Planet -- designed to create solutions for the sustainability challenges faced by the developed and developing worlds alike. Last spring, 65 teams comprising over 400 university students and advisors put their engineering skills to the test to rise to these challenges. The EPA provided selected universities with $10,000 grants for phase-one research and design, and the teams got to work. Students from California State University, Chico, crafted a strategy to locally generate solar power and facilitate a transition to energy sources in the Chico area. The New Jersey Institute of Technology proposed a national system for recycling electronics. And, the team from the University of Maine, Machias, planned the design and construction of a new college science building that uses less energy and produces fewer greenhouse gas emissions. Judges from the National Academy of Sciences narrowed the field to seven finalists. To win the overall prize, teams had to defend how their projects related to the P3 concept and prove how their work would further the goal of worldwide sustainability. Finalists included Oberline College, the University of North Carolina, Chapel Hill, the University of Colorado at Denver, the University of California, Berkeley, the Massachusetts Institute of Technology, and the University of Michigan. The team from the Rochester Institute of Technology took first prize and the $75,000 award. These five undergraduate engineering majors and two graduate students developed a low-cost solar oven for use in developing countries in Latin America. According to the students, solar ovens would reduce wood consumption, deforestation, air pollution, and related health problems. Their design consisted of glass, particleboard, and offset printing plates with a total unit cost of $32.33, or about one-fourth the price of a comparable commercially made solar oven. Since 2 billion people around the world still use organic material like wood in their daily cooking, the market for such a product -- and its positive effect on the environment -- would be huge.
