  • Patent number: 11971744
    Abstract: An example computing device includes a hinge, a first housing, a first display device disposed in the first housing, second housing rotatably coupled to the first housing via the hinge, a second display device disposed in the second housing, and a connector coupled to the hinge and the second display device. As an example, in response to a rotation of the first housing relative to the second housing, a first end of the second display device is to slide along a surface of the second housing and a second end of the second display device is to slide along a surface of the first housing.

  • Publication number: 20230176619
    Abstract: An example computing device includes a body and a first display device including a lower end that is pivotably connected to the body and a front surface including a first display area. The computing device further includes a second display device including a pivotable end that is pivotably connected to the body and a free end opposite the pivotable end. The computing device further includes a bias member connecting the second display device to the first display device. The bias member resiliently urges the free end of the second display device towards the front surface of the first display device.

  • Publication number: 20230104827
    Abstract: An example electronic device comprises a first portion including a display, a second portion, a hinge movably coupling the first portion to the second portion, and a flex-protection mechanism. The flex-protection mechanism includes a first magnetic component, a retractable bumper coupled to a second magnetic component, and a third magnetic component. In response to movement of the first portion between an open position and a closed position and magnetic interactions between the second magnetic component, the first magnetic component, and the third magnetic component, the retractable bumper moves between a retracted position and a protruded position.

  • Publication number: 20220397933
    Abstract: An example computing device includes a hinge, a first housing, and a second housing rotatably connected to the first housing via the hinge. As an example, a first display device is disposed in the first housing. The second housing includes a cover disposed along a bottom surface of the second housing, wherein the cover includes a first portion and a second portion separable from the first portion of the cover. As an example, the second portion of the cover includes an L-shaped mechanism coupled to the first portion of the cover at a first end of the L-shaped mechanism and to the first housing at a second end of the L-shaped mechanism.

  • Patent number: 11202387
    Abstract: In an example, a mounting rail may include a base and a dovetail lug. The dovetail lug may extend from the base and may also extend along a width of the base. The dovetail lug may include a bottom portion having a first thickness, and a top portion having a second thickness. The second thickness may be larger than the first thickness. In further implementations, the bottom portion and the top portion may define a front overhang and a back overhang of the dovetail lug.

  • Publication number: 20210365068
    Abstract: In example implementations, an electrical device is provided. The electrical device includes a housing and a slidable keyboard. The slidable keyboard is movably attached to the housing via a ball bearing rail system. The ball bearing rail system includes a mechanical stop to control a distance that the slidable keyboard can open to access a set of electrical components. A latch is coupled to the slidable keyboard to engage a member in the housing when the slidable keyboard is in a closed position.

  • Publication number: 20210096719
    Abstract: In example implementations, an electronic device includes a primary display, a secondary display, and a keyboard. The secondary display is coupled to the primary display. The keyboard is coupled to the secondary display and includes a first behavior key and a second behavior key. The first behavior key is to change a first display operation of the secondary display while the primary display is active. The second behavior key is to change a second display operation of the secondary display while the primary display is active.

  • Patent number: 10852850
    Abstract: An example stylus pen including a body includes a central axis, a first end, and a second end. In addition, the stylus pen includes an engagement tip disposed at the first end and including resilient cover. Further, the stylus pen includes an adjustment mechanism at least partially disposed within the body and arranged such that manipulation of the adjustment mechanism by a user causes the cover of the engagement tip to actuate between a first shape and a second shape. The cover of the engagement tip is arranged to engage with a touch sensitive surface to cause a change in a computing device when in either one of the first shape and the second shape.
