Automated Lathe:

  Evaluated noise generated while operating and made recommendation to reduce noise.

Automotive:

  Noise analysis of laminated glass in automotive windshields.

Buildings/Structures:

  Provided noise/vibration assessment of floor.

Clean Room Design:

  Reduction of vibration in a clean room in which high powered microscopes were used to conduct quality checks on electronic boards.

Cooling Systems:

  Evaluated and mapped noise generated by a refrigerator cooling system on the roof of a grocery store.

Electronic Cabinets/Enclosures

  Worked on the design, evaluation, and testing of shock control solutions for electronic cabinets/enclosures.

Engines:

  Evaluated excess vibration generated by stirling engines.
