Abstract

The present invention is a computer controlled display device. In one embodiment, the display device includes a flat panel display having an input for receiving display data. Additionally, a moveable assembly may be coupled to the display. The moveable assembly may provide at least three degrees of freedom of movement for the flat panel display device. Additionally, the moveable assembly may have a cross-sectional area, which is substantially less than a cross-sectional area of a display structure of the flat panel display. Additionally, the moveable assembly may include a plurality of stacked ball-and-socket assemblies.

11. A system as in claim 10 wherein said base is not fixedly secured to a supporting surface under said base.

12. A system as in claim 1 wherein said moveable assembly stores potential energy in a tensioned tension cable and in a plurality of compressed resilient members when said actuator is in a first state.

13. A system as in claim 1 wherein said actuator stores potential energy in a compressed spring/piston assembly when said actuator is in a second state.

14. A method, comprising:

storing a first potential energy in a tension cable extending through a longitudinal interior portion of a moveable assembly having a first end attached mechanically to a flat panel display and a second end attached to a moveable base, said moveable assembly having a plurality of moveable portions;
