  • Hybrid Automotive Vehicle with Thermoelectric Device
    Publication number: 20080245590
    Abstract: An automotive vehicle, such as an HEV, having an internal combustion engine and an electrical system. A thermoelectric device overlies the internal combustion engine and converts heat from the engine into electricity. The thermoelectric device is electrically coupled to the electrical system of the vehicle.

  • Filter-based method and system for measuring angular speed of an object
    Patent number: 6742389
    Abstract: A method and system for measuring angular speed of an object uses a micromechanical filter apparatus and allows Q-multiplication in both drive and sense modes. The invention takes advantage of the constant amplitude region of a filter spectrum within a passband of the filter apparatus to sense with a constant scaling factor that is independent of frequency variations with the passband. Thus, the system has much less sensitivity to drive mode resonance frequency shifts due to temperature variations, fabrication non-idealities and aging. The system senses angular rate or speed at resonance, which results in a great improvement over conventional gyroscopes operated off-resonance.
