CLAIMS

1. A device, comprising:

a first portion and a second portion that have hinge ends rotatably secured relative to a hinge shaft;

a u-shaped friction arm extending from a first end positioned around the hinge shaft to a second end positioned around the hinge shaft; and,

a pop-up assembly positioned along the hinge shaft between the first end and the second end and configured to create a bias to rotate the first and second portions away from one another.

2. The device of claim 1, wherein the u-shaped friction arm is curvilinear between the first and second ends.

3. The device of claim 1, wherein the u-shaped friction arm has straight side elements extending away from the hinge shaft and connected by a straight element that is perpendicular to the straight side elements.

4. The device of claim 1, wherein the u-shaped friction arm defines a first aperture at the first end and a second aperture at the second end and wherein the first and second apertures comprise radiused regions and flat regions facing the hinge shaft.

5. The device of claim 4, wherein the hinge shaft comprises a friction surface on a portion of a diameter of the hinge shaft and wherein friction between the hinge shaft and the u-shaped friction arm is greater when an individual radiused region opposes the friction surface than when an individual flat region opposes the friction surface.

6. The device of claim 1, wherein the pop-up assembly is nested within the u-shaped friction arm.

7. The device of claim 1, wherein the pop-up assembly comprises a spring.

8. The device of claim 1, wherein the pop-up assembly is configured to generate a force and wherein the force is applied to the hinge shaft during a range of rotation between the first and second portions to create the bias and wherein the force is applied to the u-shaped friction arm during a different range of rotation to create resistance to rotation around the hinge shaft.

9. The device of claim 8, wherein the pop-up assembly comprises a force transferring element that couples the force to either the hinge shaft or the u-shaped friction arm depending on an orientation of the first and second portions.

10. The device of claim 9, wherein the force transferring element comprises a pop-up arm that is biased against the u-shaped friction arm by a spring except during the

range of rotation.

11. The device of claim 10, wherein during the range of rotation a tab on the hinge shaft contacts the pop-up arm and forces the pop-up arm away from the u-shaped friction arm.

12. The device of claim 11, wherein the contact between the pop-up arm and the tab on the hinge shaft creates the bias to rotate the first and second portions away from one another.

13. A device, comprising:

a first portion that includes a first display and that is rotatably coupled by a hinge assembly to a second portion that includes a second display; and,

a spring that is, based upon an orientation of the first and second portions, alternatively coupled to the first and second portions to bias the first and second portions away from one another or the spring is coupled to the hinge assembly to increase resistance to rotation of the first and second portions.

14. The device of claim 13, wherein the hinge assembly comprises a pop-up arm and a friction arm and wherein the pop-up arm couples or decouples the spring from the friction arm depending on the orientation of the first and second portions.

15. The device of claim 14, wherein the friction arm is u-shaped from a first end positioned around a hinge shaft of the hinge assembly to a second end positioned around the hinge shaft.
