Abstract: An apparatus having a fast drop-off in attraction force between magnets is provided. The apparatus includes a first magnet array having a plurality of magnets with different magnetic field orientations fixedly positioned in a first housing. The apparatus also includes an adjacent magnet assembly relative to the first magnet array and provided in a second housing that includes second and third magnet arrays, each having a plurality of magnets with different magnetic field orientations. The apparatus includes an activation mechanism configured to move the adjacent magnet assembly from at least a first relative position to a second relative position. The adjacent magnet assembly in the second relative position has a second magnetic attraction force with the first magnet array that is substantially reduced as compared to a first magnetic attraction force with the first magnet array in the first relative position.

Abstract: The description relates to hinged devices, such as hinged computing devices. One example can include a first portion and a second portion that have hinge ends rotatably secured relative to a hinge shaft. The example can also include 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.

Abstract: The description relates to hinged devices, such as hinged computing devices. One example can include a hinge assembly that rotatably secures a first portion and a second portion relative to a hinge axis and defines a planar conductor path between the first and second portions through the hinge assembly. The example can also include a pop-up arm that compresses a spring when the first portion and the second portion are rotated to a closed orientation, and wherein the compressed spring creates a bias to rotate the first and second portions from the closed orientation to an open orientation.

Abstract: The description relates to hinged devices, such as hinged computing devices. One example can include a first portion and a second portion. The example can also include a pair of self-spacing hinge assemblies rotatably securing hinge ends of the first and second portions and camming the first and second hinge ends apart from one another at non-parallel orientations of the first and second portions sufficient to prevent contact of the first and second hinge ends at the non-parallel orientations while allowing the first and second hinge ends to contact one another at other orientations.

Abstract: Techniques are described herein that are capable of enabling a mounting system to receive threaded and threadless posts. The mounting system may have a cavity (a.k.a. void) that is configured to receive such posts. An interior surface of the cavity may include threads to allow corresponding threads of a threaded post to be twisted (e.g., screwed) into the threads of the cavity. The threads of the cavity may be configured to allow a threadless post to pass through the cavity without being encumbered by the threads. The mounting system uses magnetism and a taper of the cavity to facilitate magnetically and frictionally engaging the threadless post in the cavity.

The hinge assembly can include an element that rotates around the hinge axis and moves toward and away from the hinge axis.

Abstract: A mechanical attach and retention feature is described. An apparatus may include a cover portion that is configured to cover at least a portion of a display device of a computing device having a mobile form factor that is configured to be held by one or more hands of a user. The apparatus includes, a first mid-spine that is rotationally connected to the cover portion, a second mid-spine that is rotationally connected to the first mid-spine, and a connection portion that is rotationally connection to the second mid-spine. The connection portion is configured to form a removable physical coupling to the computing device using a projection that is configured to be disposed within a channel formed in a housing of the computing device and a protrusion disposed on the projection, the protrusion configured to be received within a cavity formed as part of the channel.

Abstract: Flexible hinge spine techniques are described. In one or more implementations, a flexible hinge is configured to communicatively and physically couple an input device to a computing device and may implement functionality such as a support layer and minimum bend radius. The input device may also include functionality to promote a secure physical connection between the input device and the computing device. One example of this includes use of one or more protrusions that are configured to be removed from respective cavities of the computing device along a particular axis but mechanically bind along other axes. Other techniques include use of a laminate structure to form a connection portion of the input device.

Abstract: A cover for a mobile computing device includes two or more hinges so constructed that the hinges are substantially rigid when in-plane and flexible when out-of-plane. The cover includes segments made of a rigid material disposed between the hinges. The cover, when swiveled to the back side of the computing device, forms a contour around an object such as a stylus to secure the object to the back side of the computing device when the object is present. The cover becomes substantially flat and parallel to the back side of the computing device when the object is absent.

Abstract: The description relates to devices, such as computing devices that have hinged portions. One example can include a first portion and a second portion. This example can also include a multi-pivot hinge unit rotatably securing the first and second portions. This example can further include a set of rigid hinge cover portions that are configured to be able to rotate relative to one another while collectively covering the multi-pivot hinge unit.

The locking receptacle may include a rotating lock and may have an aperture through which the locking protrusion is insertable. The computing device may include an actuator mechanically coupled to the locking mechanism and configured to unlock the first portion from the second portion.

Abstract: The description relates to devices that include hinged portions and controlling rotation of the portions. One example can include a display coupled to a first end of an arm. The example can also include a base rotatably secured to a hollow shaft that is fixed to the arm. The hollow shaft defines an axis of rotation of the arm relative to the base. The base can also include first and second opposing axial cam elements positioned on the hollow shaft and a spring positioned on the hollow shaft. The first and second opposing axial cam elements can be oriented relative to one another such that rotation of the arm toward the base causes the first and second axial cam elements to move away from one another along the hollow shaft thereby compressing the spring.

The example can also include a pair of self-regulating hinge assemblies rotatably securing hinge ends of the first and second portions around a first hinge axis associated with the first portion and a second hinge axis associated with the second hinge axis so that an extent of rotation around the first hinge axis corresponds to an extent of rotation around the second hinge axis. The example can also include a first display positioned on the first portion and wrapped around the hinge end between the pair of self-regulating hinge assemblies. The example can further include a second display positioned on the second portion and wrapped around the hinge end between the pair of self-regulating hinge assemblies.
