  • Control of magnetorheological mount
    Patent number: 8672104
    Abstract: A system and method of controlling engine vibration mounted within a vehicle including at least one hydraulic mount, each mount including a fluid chamber. A pair of accelerometers sense relative acceleration across the mount between the engine and the frame and generate a relative acceleration signal. A control unit is electrically connected to the accelerometers. The control unit is adapted to generate an electronic control signal in response to the relative acceleration signal. The control device is responsive to the electric control signal for controlling the damping force of the hydraulic mount. A control algorithm calibrates the control unit such that maximum vibration damping occurs at and around the engine resonance bounce frequency.

  • Method and apparatus for surgical pocket creation and dissection
    Patent number: 7927331
    Abstract: A surgical instrument for creation of tissue dissection and creation of space is disclosed. The instrument may be used any place in the body where a physician could or would use finger or instrument dissection to create a tissue pocket or space. The pocket dissector can be used under direct vision, laparoscopically, endoscopically, under fluoroscopic guidance or blindly.
