  • Publication number: 20100002301
    Abstract: An image stabilizer includes a rotor including a lens assembly, and configured to move perpendicular to an optical axis of light passing through the lens assembly, and a suspension unit configured to support movement of the rotor and to prevent the rotor from moving non-perpendicular to the optical axis of the light passing through the lens assembly. Accordingly, the image stabilizer prevents variance of characteristics of a rotor in a low frequency band according to the position and distortion of phase characteristics in a high frequency band. Therefore, the image stabilizer has consistent operation characteristics regardless of the position, posture, and movement of a person using an image capture device containing the image stabilizer.

  • Patent number: 4486729
    Abstract: A magnetic road is provided with a series of magnets having the same pole oriented upwards and an upstanding non-magnetic sidewall extending along at least one side. A magnetic object is provided having longitudinally spaced magnets which either have that same pole oriented downwards, or arranged in corresponding annuli having that same pole oriented radially outwards. In the first instance, additional provisions are made to prevent the object from rolling over. Accordingly, the object can translate along the road adjacent the sidewall while floating on mutually repelling magnetic forces.
