  • Actuator
    Patent number: 7638906
    Abstract: An actuator including at least one moving body, at least one fixed body and a connecting member is provided. The moving body is suitable for moving along a direction, and includes at least one coil. In addition, the fixed body includes a permanent magnet and a yoke, wherein the coil is disposed between the permanent magnet and the yoke, and the polarity direction of the permanent magnet is parallel to the moving direction of the moving body. Furthermore, the connecting member is used for connecting the moving body and the fixed body. The actuator meets the requirements of miniaturization, low power consumption and low cost.
    Type: Grant

  • Optical devices
    Patent number: 7365922
    Abstract: An optical device. A lens module is movably disposed in a lens housing. A drive mechanism is connected to the lens module, driving the lens module along an optical axis of the lens module. A brake mechanism is disposed between the lens housing and the lens module and moves perpendicular to the optical axis, fixing and releasing the lens module. When the brake mechanism releases the lens module, the lens module moves along the optical axis.
