ViaLogy PLC05 April 2007 Date: 5 April 2007On behalf of: ViaLogy plc ("ViaLogy" or "the Company") For Immediate Release ViaLogy plc Technology Update • ViaLogy offers aerospace industry a highly scaleable platform for integrating emerging wireless MEMS and RFID Devices • Will potentially accelerate adoption of lightweight composites for aerospace and semiconductor applications LONDON, April 5, 2007 -- ViaLogy plc (AIM: VIY): ViaLogy presented a network-centric interoperable sensor- signal- processing platform deployingembedded MEMS and RFID sensors at the CANEUS/NASA "Fly-By-Wireless" Workshopheld in conjunction with the 5th Annual RFID World Congress in Grapevine, TX. Lightweight composites are becoming increasingly important in aircraft,aerospace structures, transportation systems and underground oil and gaspipelines. To date, most of the work has focused on deploying and machiningcomposites for control surfaces, skin, structures and cryogenic tanks andvessels. While high stiffness, strength, superior fatigue tolerance to thermalvariations and stealthy radar cross section make composites very attractive,their adoption has been rather limited due to high cost, manufacturability,complex failure mechanisms and maintainability. Typically, design-to-reliabilitychallenges can be overcome with additional structure health monitoring circuitryand sensors. However, this is very difficult to achieve for composites withcurrent technology, without surface mounting hundreds of hardwired stress andstrain gauges and other sensors to detect incipient micro-fracture which canrapidly degenerate to total structure failure. Thus aerospace and reusablelaunch vehicle engineering has been limited in exploiting the promise ofcomposites due to weight and power overhead from additional sensors. ViaLogy's Pulsed Microwave Data Link (PMDLTM) platform combines synergisticadvances in MEMS sensors, power optimized active radio-frequency (RF) scanningfor embedded MEMS/RFID tag interrogation, internet protocol-enabled MEMSinteroperability for wireless interconnect switches, smart summarization andweak signal processing to extract diagnostic signatures. ViaLogy has a patentpending on this solution. PMDLTM addresses two challenges unique to embedded wireless MEMS/RFIDimplementations with inherent requirements for high scalability; namelycontinuous monitoring for degradation, recalibration and mortality of thedevices themselves and resulting uncertainty in signature quality, and abilityof proprietary weak signal processing to robustly extract failure-modes andsignatures in high clutter RF environments with complex propagation propertiesintrinsic to molecular constructs seen in composites. Dr. Sandeep Gulati, ViaLogy CTO and VP for Product Development, commented; "Weare focused on broad market applications where our network centric and sensoragnostic weak signal processing platform becomes an enabler. In addition, we seea convergence between our wireless MEMS and RFID solutions and an immediatevalue proposition in increasing RFID read accuracy for embedded tags in theaerospace industry." Dr. John Mai, Product Manager for RFID Platforms, recently joined ViaLogy tohead this effort. Previously, Dr. Mai was the Special Assistant to the GeneralDirector of the RFID Technology Center (RTC) within the Industrial TechnologyResearch Institute, Hsinchu, Taiwan. There, he was involved with all of theCenter's advanced projects ranging from all-printed RFID developments to next-generation, compact UHF RFID readers. He also initiated a polymer-MEMS device R&D program between the RTC and Stanford University. According to Dr. Mai, an aerospace engineer by training; "Localizing a crack ina epoxy composite cryogenic propellant tank using embedded MEMS sensors orcorrectly reading a metallic RFID tag embedded within a multilayer compositeprinted circuit board, buried deep in a loaded pallet present the same clutterrejection challenge. There is an economic penalty which can quickly propagateand escalate for missed detection in both cases." He added, "As the supply-chainindustry moves towards item level tagging, fast and accurate read capabilityenabled by PMDLTM, will become a market differentiator". Dr. Mai is leveraging his experience in business with the Asia-Pacific region toposition this ViaLogy solution into a market that it is believed could consume48% of the world's RFID tags by 2010.
