10. The computer controlled display device of claim 8, wherein said first joint member and said second joint member become fixed in a selected position through frictional contact.

11. The computer controlled display device of claim 10, wherein a plurality of U-joints extend from said base to said flat panel display.

12. The computer controlled display device of claim 11, wherein a tension cable is disposed within said moveable assembly.

13. The computer controlled display device of claim 12, further comprising an actuation device operatively coupled to said tension cable, said actuation device suspending a movement of said moveable assembly when a force is applied by said actuation device and permitting said movement when said force is released.

14. The computer controlled display device of claim 13, wherein said force is applied to said tension cable to engage said teeth of said first joint member and said second joint member.

15. The computer controlled display device of claim 13, wherein said force is released from said tension cable to separate said teeth of said first joint member and said second joint member.

16. The computer controlled display device of claim 13, wherein said force is torque.

17. The computer controlled display device of claim 1, wherein said moveable assembly has one of a data cable, power cable, tension mechanism, and an anti-torsion mechanism.

18. The computer controlled display device of claim 1, wherein said moveable assembly comprises at least one pivot joint disposed near said base.

19. The computer controlled display device of claim 18, wherein said at least one pivot joint has a knuckle and at least one friction plate disposed on said knuckle.

20. The computer controlled display device of claim 19, wherein a plurality of frictions plates are disposed between a first pivot joint and a second pivot joint.

21. The computer controlled display device of claim 20, wherein a tension cable is disposed within said moveable assembly.

22. The computer controlled display device of claim 18, wherein said moveable assembly has one of a data cable, power cable, tension mechanism, and an anti-torsion mechanism.

23. The computer controlled display device of claim 21, further comprising an actuation device operatively coupled to said tension cable, said actuation device suspending a movement of said moveable assembly when a force is applied by said actuation device and permitting said movement when said force is released.

24. The computer controlled display device of claim 23, wherein said force is applied to said tension cable to engage said plurality of friction plates with said first and second pivot joints.

25. The computer controlled display device of claim 23, wherein said force is released from said tension cable to separate said plurality of friction plates from said first and second pivot joints.
