1. A device, comprising:
- a base assembly that includes a processor and is configured to define a lower axis of rotation;
a display assembly including a display that is driven by the processor and configured to rotate around an upper axis of rotation; and
,an arm assembly extending from the base assembly at the lower axis of rotation to the display assembly at the upper axis of rotation, the arm assembly comprising a five bar linkage comprising;
a hollow arm configured to operate as a first elongate link of the five bar linkage,an upper link configured to operate as a second link of the five bar linkage,a lower link configured to operate as a third link of the five bar linkage,a pair of redundant elongated links configured to operate as a fourth elongate link and a fifth elongate link of the five bar linkage, the pair of redundant elongated links being contained within the hollow arm, having lower ends and upper ends, extending between the lower link and the upper link, and including biasing elements that adjust lengths of the pair of redundant elongated links such that the pair of redundant elongated links are under stretching tension that biases the lower ends and the upper ends towards each other.

Abstract
The description relates to devices, such as computing devices having displays that can be rotated through a range of travel. The device can counter-balance the display to create a near weightless feel for the user when repositioning the display.

13. A device, comprising:
-
a base assembly that includes a processor and is configured to define a lower axis of rotation; a display assembly including a display that is driven by the processor and configured to rotate around an upper axis of rotation; and
,an arm assembly extending from the base assembly at the lower axis of rotation to the display assembly at the upper axis of rotation, the arm assembly comprising a hollow arm and a pair of first and second redundant elongated links extending between the lower axis of rotation and the upper axis of rotation, the first redundant elongated link including a length adjuster that controls an overall length of the first redundant elongated link such that the first redundant elongated link is under stretching tension and a lower end and an upper end of the first redundant elongated link are biased towards each other, wherein the first redundant elongated link is secured on a first side of the lower axis of rotation and the upper axis of rotation and the second redundant elongated link is secured on a second opposite side of the lower axis of rotation and the upper axis of rotation. - View Dependent Claims (14, 15, 16, 17)

18. A device, comprising:
-
a base assembly that defines a lower axis of rotation; a display assembly including a display that rotates around an upper axis of rotation; and
,an arm assembly extending from the lower axis of rotation of the base assembly to the upper axis of rotation of the display assembly, the arm assembly further comprising a hollow arm configured to operate as one elongate link in a four bar linkage between the lower axis of rotation and the upper axis of rotation, an outer link including a lower end secured on a first side of the lower axis of rotation and an upper end secured to the first side of the upper axis of rotation, and an inner link including a lower end secured on a second opposite side of the lower axis of rotation and an upper end secured on the second opposite side of the upper axis of rotation, wherein the inner and outer links both include tensioning elements that control lengths of the inner and outer links such that the inner and outer links remain under stretching tension that biases the lower ends and the upper ends towards each other when the display rotates and cooperatively operate as another elongate link of the four bar linkage. - View Dependent Claims (19, 20, 21)
