A number of research projects I have worked on for the past several years:

MIT:

  • Electromechanical Valve Drive:

    W.S. Chang, T.A. Parlikar, M.D. Seeman, D.J. Perreault, J.G. Kassakian and T.A. Keim, "A New Electromagnetic Valve Actuator," in IEEE Workshop on Power Electronics in Transportation, pp. 109-118, Auburn Hills, MI, October 24-25, 2002.

    Y.H. Qiu, T.A. Parlikar, W.S. Chang, M.D. Seeman, T.A. Keim, D.J. Perrealt and J.G. Kassakian, "Design and Experimental Evaluation of An Electromechanical Engine Valve Drive," 35th Annual IEEE Power Electronics Specialists Conference, Aachen, Germany 2004, pp. 4838-4843.

    T.A. Parlikar, W.S. Chang, Y.H. Qiu, M.D. Seeman, D.J. Perreault, J.G. Kassakian, T.A. Keim, "Design and experimental implementation of an electromagnetic engine valve drive," IEEE/ASME Transactions on Mechatronics, Oct. 2005, pp. 482-494.

UC Berkeley:

  • Micro Glider: Working on the 5mW, 200V supply for piezo drive. The out-of-date glider web site.
