  • Patent number: 7239106
    Abstract: A reeving system for filming movies, sporting events, or any other activity that requires fluid movement of a camera or other object to any position within a defined volume of space. To accomplish positioning embodiments move an object throughout three-dimensional space by relocating one or more lines that are feed through a plurality of opposing sides of the object. These line(s) (e.g., a cable, rope, string, cord, wire, or any other flexible connective element) which support the object from above or below the object within a volume of space are arranged in way that allows the object to be rapidly moved to and from any location within the defined volume of space. For instance, the system may be arranged to perform dimensional movement using one line configured as an endless loop, one line configured as a half loop, two lines configured as endless loops or two lines configured as half loops.

  • Patent number: 7127998
    Abstract: Embodiments of the invention move objects throughout two-dimensional and three-dimensional space by using a movement line that is coupled with a plurality of opposing sides of the platform. The movement line is used to control the horizontal axis motion and Z-axis motion of the platform and is designated the horizontal movement line. Displacing a portion of the horizontal movement line allows vertical displacement of the platform to be traversed. There is no need for a complex computer control system since the Z-axis displacement is substantially independent of horizontal movement over a coverage area serviced by the platform. Nested embodiments utilizing one or more rope allow for three-dimensional movement of an object or angular displacement of an object with respect to the vertical axis. A mounting beam for positioning and supporting the Z-axis and horizontal axis motors and visual display element(s) and other optional multimedia devices may also be positioned independently of the platform.

  • Patent number: 6975089
    Abstract: Embodiments of the invention are ideally suited for use filming movies, sporting events, or any other activity that requires fluid movement of a camera or other object to any position within a defined volume of space. To accomplish such positioning embodiments of the invention are configured to move an object throughout three-dimensional space by relocating one or more lines that are feed through a plurality of opposing sides of the object. These line(s) (e.g., a cable, rope, string, cord, wire, or any other flexible connective element) which support the object from above or below the object within a volume of space are arranged in way that allows the object to be rapidly moved to and from any location within the defined volume of space. For instance, the system may be arranged to perform dimensional movement using one line configured as an endless loop, one line configured as a half loop, two lines configured as endless loops or two lines configured as half loops.

  • Publication number: 20050087090
    Abstract: Embodiments of the invention move objects throughout two-dimensional space by using a support line that is coupled with both opposing sides of the platform. This line controls the Y-axis motion and Z-axis motion of the platform and is designated the YZ movement line. Displacing a portion of the YZ movement line allows vertical displacement of the platform to be traversed. There is no need for a complex computer control system since the Z-axis displacement is substantially independent of horizontal movement over a coverage area serviced by the platform. A mounting beam for positioning and supporting the Z-axis and Y-axis motors and visual display element(s) and other optional multimedia devices may also be positioned independently of the platform. In addition, since the line is commanded from one point, distantly located motors and electrical cables are not required.
