Micromachine for Diagnostics SBIR Background

• Small Business Innovation Research
• Sponsored by National Automotive Center in TARDEC
• COTR Andrew Scott, TARDEC Robotics Mobility
  Laboratory
• Phase II commenced 2/14/03

4
Program Vision

• TARDEC expressed interest in a MEMS chip that
  can be targeted to multiple diagnostic and
  prognostic applications on the vehicle and
  produced in high volumes
• MEMS Micro Electro-Mechanical Systems
• ASTI added wireless digital communications as a
  critical element of an embedded diagnostics
  architecture

An Embedded Diagnostics and Prognostics
Architecture

• Why an architecture?
• Everything essential has its place
• Elements are arranged to work well together
• Design can be altered to fitclient/customers
  needs
• Provisions for future additions

7
Challenges to an Embedded Diagnostics and
Prognostics

• Premise dedicated sensors will improve
  diagnostic and prognostic capability.
• How to integrate more and more sensors (MEMS and
  conventional) at reasonable cost and complexity?
  ? Wireless communication inside the vehicle
  (AKA cable replacement)
• How to effectively present diagnostic and
  prognostic alerts to vehicle operators?? Vehicle
  bus integration, graphical displays
• How to efficiently communicate diagnostic and
  prognostic results to maintainers and the
  logistics community?? Vehicle bus integration ?
  Wireless communication outside the vehicle (e.g.
  Bluetooth)
