- 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 /PRNewswire-FirstCall/ -- ViaLogy plc (AIM: VIY):
ViaLogy presented a network-centric interoperable sensor- signal-
processing platform deploying embedded MEMS and RFID sensors at the
CANEUS/NASA "Fly-By-Wireless" Workshop held 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 gas
pipelines. To date, most of the work has focused on deploying and machining
composites for control surfaces, skin, structures and cryogenic tanks and
vessels. While high stiffness, strength, superior fatigue tolerance to
thermal variations 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- reliability challenges can be overcome with
additional structure health monitoring circuitry and sensors. However, this
is very difficult to achieve for composites with current technology,
without surface mounting hundreds of hardwired stress and strain gauges and
other sensors to detect incipient micro-fracture which can rapidly
degenerate to total structure failure. Thus aerospace and reusable launch
vehicle engineering has been limited in exploiting the promise of
composites due to weight and power overhead from additional sensors.
ViaLogy's Pulsed Microwave Data Link (PMDL(TM)) platform combines
synergistic advances in MEMS sensors, power optimized active
radio-frequency (RF) scanning for embedded MEMS/RFID tag interrogation,
internet protocol- enabled MEMS interoperability for wireless interconnect
switches, smart summarization and weak signal processing to extract
diagnostic signatures. ViaLogy has a patent pending on this solution.
PMDL(TM) addresses two challenges unique to embedded wireless MEMS/RFID
implementations with inherent requirements for high scalability; namely
continuous monitoring for degradation, recalibration and mortality of the
devices themselves and resulting uncertainty in signature quality, and
ability of proprietary weak signal processing to robustly extract
failure-modes and signatures in high clutter RF environments with complex
propagation properties intrinsic to molecular constructs seen in
composites.
Dr. Sandeep Gulati, ViaLogy CTO and VP for Product Development,
commented; "We are focused on broad market applications where our network
centric and sensor agnostic weak signal processing platform becomes an
enabler. In addition, we see a convergence between our wireless MEMS and
RFID solutions and an immediate value proposition in increasing RFID read
accuracy for embedded tags in the aerospace industry."
Dr. John Mai, Product Manager for RFID Platforms, recently joined
ViaLogy to head this effort. Previously, Dr. Mai was the Special Assistant
to the General Director of the RFID Technology Center (RTC) within the
Industrial Technology Research Institute, Hsinchu, Taiwan. There, he was
involved with all of the Center'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 in a epoxy composite cryogenic propellant tank using embedded MEMS
sensors or correctly reading a metallic RFID tag embedded within a
multilayer composite printed circuit board, buried deep in a loaded pallet
present the same clutter rejection challenge. There is an economic penalty
which can quickly propagate and escalate for missed detection in both
cases." He added, "As the supply-chain industry moves towards item level
tagging, fast and accurate read capability enabled by PMDL(TM), will become
a market differentiator".
Dr. Mai is leveraging his experience in business with the Asia-Pacific
region to position this ViaLogy solution into a market that it is believed
could consume 48% of the world's RFID tags by 2010.
