Abstract: The description relates to hinged devices. One example relates to a device that has a first portion hingedly secured along a spine and a second portion hingedly secured along the spine. The example can also include a first spine cover secured relative to the spine and extending into the first portion and a second spine cover secured relative to the spine and extending into the second portion. An extent to which the first spine cover extends into the first portion and the second spine cover extends into the second portion is controlled by an angular orientation of the first and second portions.

Abstract: A closure device includes a first magnet and a housing with a second magnet positioned therein. The first magnet is configured to be position in a first object and the housing is configured to be positioned in a second object. The housing has a top end and at least one adjustment mechanism connected to the housing that moves the second magnet in at least one translational direction or at least one rotational direction relative to the top end of the housing. The movement of the second magnet relative to the top end of the housing adjusts the position or orientation of the second magnet relative to the first magnet to alter a magnetic force between the first magnet and the second magnet when the first magnet is positioned proximate the top end of the housing.

The hinge assembly includes a hinge core, a timing element, a first linkage component rotatably coupling the hinge core to the first portion, a first hinge guide rotatably coupling the hinge core to the first portion, a second linkage component rotatably coupling the hinge core to the second portion, and a second hinge guide rotatably coupling the hinge core to the second portion. The first linkage component defines one or more helical surfaces that interface with the timing element, and the second linkage component defines one or more helical surfaces that interface with the timing element. The timing element coordinates rotation of the first linkage component with rotation of the second linkage component.

Abstract: Hinged computing devices often connect two components via one or more hinges, using either a door-hinge style or other conventional hinge style. Presenting a continuous visual impression of the computing device to the user, with any gaps covered, provides protection to internal components and suggests a higher overall quality of the computing device to the user. Using conventional hinges, achieving a 360-degree range of motion is difficult, and often requires a pair of hinges connected by a spine to accommodate the respective thicknesses of the two hinged components in all orientations. However, using a pair of conventional hinges connected by a spine to achieve a 360-degree range of motion can yield a variable gap between the spine and the hinged components. The presently disclosed technology is directed to mechanically deterministic sliding covers that conceal these variable gaps, while still maintaining a 360-degree range of motion of the computing device.

Abstract: The description relates to hinged devices, such as hinged computing devices. One example can include a first portion and a second portion that are rotatably secured relative to a hinge axis through a range of rotation from a closed orientation to an open orientation. The example can also include an oblong friction shaft and a friction band secured to the first portion and defining an oblong aperture configured to receive the oblong friction shaft. At the closed orientation a major axis of the oblong friction shaft is aligned with a major axis of the oblong aperture to provide a relatively low resistance to rotation and at the open orientation the major axis of the oblong friction shaft is rotated relative to the major axis of the oblong aperture to provide a relatively high resistance to rotation.

A tensioned element includes an upper segment attached to the first optical module and a lower segment attached to the second optical module. Movement of the tensioned element thus generates opposing movement of the first and second optical modules, the first optical module moving in a direction parallel to a direction of movement of the upper segment, and the second optical module moving in a direction parallel to a direction of movement of the lower segment.
