  • Recoilless voice coil actuator and method
    Patent number: 7755225
    Abstract: A recoilless voice coil actuator and method having flexures connected to both the magnet and the voice coil allowing independent movement of both the magnet and the voice coil in the direction of actuation. The stiffness or resistance to movement of the flexures is selected so that the natural frequencies of the magnet and the voice coil along the direction of actuation are substantially the same.
    Type: Grant
    Filed: March 31, 2008
    Date of Patent: July 13, 2010
    Assignee: Electro Scientific Industries, Inc.
    Inventor: James Samir Ismail

  • Automated tool for precision machining and imaging
    Patent number: 5831181
    Abstract: A modified Atomic Force Microscope (AFM), which can machine and image the surface of a sample with nanometer precision in all three orthogonal directions by varying the depth-of-cut of the sample. A multi-repetitive sensor system is provided as is a radially halved quartered electrode to substantially maintain parallelism or substantial parallelism.
