Abstract: The description relates to hinged devices, such as hinged computing devices. One example can include a first portion associated with a first axial timing surface and a second portion associated with a second axial timing surface. The example can also include a clutch stack spanning between the first portion and the second portion and a timing shuttle configured to engage the first and second axial timing surfaces to synchronize rotation of the first and second portions through a range of rotation. The example can include orientation dependent cams that control compression of the clutch stack as the first and second portions rotate through the range of rotation.

Abstract: The description relates to hinged devices, such as hinged computing devices. One example can include a first portion including a display and a second portion including an input device. This example can also include a hinge assembly rotationally securing the first and second portions through a range of angular orientations and a sensor positioned relative to the hinge assembly and configured to sense relative linear positions of the hinge assembly that correspond to angular orientations of the first and second portions.

Abstract: The description relates to hinged devices, such as hinged computing devices and accessories. One example can include a first portion and a second portion that are rotatably secured by a hinge shaft through a range of rotation from a closed orientation to a fully open orientation. A friction sub-assembly can be positioned on the hinge shaft and configured to create resistance to rotation during a first sub-range of rotation that ranges from the fully opened orientation to an intermediary orientation. A biasing sub-assembly can be positioned on the hinge shaft and configured to create a bias force during a second sub-range of rotation that ranges from the intermediary orientation to the closed orientation and the biasing force biases the first and second portions to an individual orientation within the second sub-range of rotation.

Abstract: The presently disclosed compliant magnetic locking mechanisms provide mechanism(s) and method(s) for latching a cover (e.g., a rear cover) to a device body that is quick assembling, low cost, easily recyclable, secure, and/or leaves no exposed fasteners. A bi-stable (or mono-stable) compliant mechanism inside the cover actuates a set of latches in and out. This action serves to lock and unlock the cover or other removable portion of the computing device. The compliant magnetic locking mechanisms may contain an array of magnets, which can be used in conjunction with a magnetic key to actuate the compliant mechanism from the exterior.

Abstract: The description relates to hinged devices, such as hinged computing devices that include a pop-up function. One example can include a first portion and a second portion that are rotatably secured through a range of rotation from an open orientation to a closed orientation. This example can also include a selective isolation assembly configured to convert rotational torque associated with rotating the first and second portions toward the closed orientation to a compressive force that compresses a spring. The selective isolation assembly is configured to disconnect the first and second portions and the compressed spring as the first and second portions approach the closed orientation.

Abstract: The description relates to hinged devices, such as hinged computing devices. One example can include a first portion secured to a first hinge arm that is configured to rotate around a first hinge axis and a second portion secured to a second hinge arm that is configured to rotate around a second hinge axis. A timing shuttle can be positioned on a central shaft that is located between the first hinge axis and the second hinge axis and is configured to control a frictional torque experienced by the first and second hinge arms depending upon orientation of the first and second hinge arms and to synchronize rotation of the first and second hinge arms around the first and second hinge axes.

Abstract: The description relates to hinged devices. One example can include a spine defining inner and outer arced surfaces and a hinge arm positioned between the inner and outer arced surfaces and configured to arcuately move from a retracted position to a fully extended position. The example includes an anti-lock link captured between the spine and the hinge arm to move along an arc. Rotation of the hinge arm to the fully extended position is configured to rotate the anti-lock link along the arc and partially out of the spine until the anti-lock link contacts the spine and blocks further extension of the hinge arm. Reverse rotation of the hinge arm from the fully extended position toward the retracted position is configured to initially cause the hinge arm to contact the anti-lock link and not the outer arced surface.

Abstract: The description relates to hinged devices. One example can include a flexible display extending over a major surface of a first portion across a hinge assembly and over a major surface of a second portion. The hinge assembly can include a pair of hinge sub-assemblies that include elongate slider links that extend along a length from proximal ends that are rotationally secured to the hinge assembly to distal ends that are slideably secured to the first portion. The hinge assembly can also include an auxiliary hinge sub-assembly interposed between the pair of hinge sub-assemblies and comprising a truncated elongate slider link that extends along a length that is less than the length of the elongate slider links and extends from a proximal end that is rotationally secured to the hinge assembly to the distal end that is slideably secured in the first portion.

Abstract: The presently disclosed secure electromagnetic docking systems provide a simplified locking interface for the user and improved security overall. The secure electromagnetic locking mechanisms are hidden from view and access by a would-be thief, which is distinct from the generally accessible nature of prior art cable and lock mechanisms. The secure electromagnetic docking systems may also be locked and unlocked via a graphical user interface (GUI), thereby eliminating a requirement that the user successfully secure a cable and lock mechanism to a computing device and a fixed object. The secure electromagnetic docking systems may comprising one or more ferromagnetic structures are biased to a locked position. An electromagnet is selectively powered to move the one or more ferromagnetic structures to an unlocked position. In the unlocked position, one or more spring loaded ejectors are permitted to eject the computing device from the base.
