1 Small Business Innovation Research: A Deployable Wireless Architecture for Sensor-Based Embedded Diagnostics and Prognostics on Ground Vehicles SBIR #A June 10, 2003 Michael Losh, VP Core Technology American Systems Technology Incorporated

ASTI ASTI Founded in 1992 Background: delivering embedded software and tools for automotive controls development to OEMs and first-tier suppliers 8(a)-certified by SBA, 6 years of eligibility remaining Headquarters in Troy, Michigan.

ASTI “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

ASTI 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

ASTI Embedded Diagnostic s and Prognostic s Motivations Readiness Sustainability Performance Commercial Trends Safety Longevity FCS BCT Legacy Commercial

ASTI 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 fit client/customer’s needs Provisions for future additions

ASTI 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)
