  • Method and device for automatically controlling a polarizing filter
    Patent number: 6492635
    Abstract: A method and device for automatically controlling a polarizing filter, featuring automatically sensing, measuring, and analyzing at least one parameter associated with direction of a polarizing filter by an electronic direction/motion sensing mechanism, receiving a signal from the electronic direction/motion sensing mechanism relating to the at least one parameter associated with direction of the polarizing filter by a rotation control circuit, and receiving a signal from the rotation control circuit relating to the at least one parameter associated with direction of the polarizing filter by a polarizing filter rotating mechanism for automatically rotating the polarizing filter.

  • Rolling weighted base
    Patent number: 6435468
    Abstract: A rolling weighted base for supporting an object and for facilitating the movement of the object along a surface, the base connected to the object by a vertical shaft, the base comprising: at least three weight balls; a housing configured to receive the vertical shaft and to hold the at least three balls rigidly spaced apart so that the at least three balls do not touch each other, the at least three balls partially protruding from said housing toward the hard surface and free to rotate inside the housing.
