                                       1
Automotive – Seat Structural Analysis and Testing
• Structural Analysis - FEA
     • Performed analyses of FMVSS 207 / 210 loading conditions

           •   DAEWOO (GM) Nubira

           •   Jeep Wrangler (XJ)



• Structural Analysis – Defense Litigation Support
     • Prepared casework as part of Holmes v Ford, et al.

     • Reviewed FMVSS 207 / 210 test data for a

        multitude of cars, pickup trucks and SUVs.

     • Analyzed plaintiff dynamic testing and assisted

        defense counsel / fellow experts.

Automotive / Aviation / Military – Design
•    Structural integrity of seat system including seatbelts
     • Analyzed seatbelt components - FMVSS 207 / 210 loads

•    Seatbelt routing, accessibility and strength per FMVSS 209
     • Application engineering for seatbelts to ensure proper seatbelt
       strength, routing and accessibility standards were met.

     • Worked with automotive (VW, Ford), military and executive aviation
       customers to meet their needs.

Military – Gunner Turret Sling Seat - Background
• Design and Program Responsible
     • Meet cost and timing targets
     • DFM - Used Spanish skills to build team / improve manufacturability
     • Build supply base / reduce supplier costs
• Design parameters
     • Increased user comfort               Improve ingress / egress
     • Easily installed with no hardware changes
     • Develop integral EA device to improve gunner survivability
• Final Project Results – System Mine Blast Performance
     • First gunner sling seat to pass all injury numbers
     • Reduces lumbar load / pelvic acceleration consistently
     • EA capability remaining post-test (heavy occupant / more severe blast)

Military – Gunner Turret Sling Seat - Results
• Program / Design Results
     • All customer concerns / design targets and timing addressed

     • Capabilities not found in other competitor’s sling seats

           •   Energy Absorption capabilities (EA)   Padded adjustable seat back / rest

           •   Contoured seat base                   Dual emergency release shackles

     • Maintained BOM cost / sales price while adding content
     • Opportunity for $ 18 MM business
     • Increased component supplier base  resulted in secondary program
       cost reductions
