Abstract: Systems and methods for aligning an electronic device to a wireless charging pad disposed under a work surface are described. In some embodiments, a system may include a printed circuit board (PCB) and a light indicator coupled to the PCB, where the light indicator is configured to connect to a wireless charging pad disposed under a work surface, and where light emitted by the light indicator is visible to a user from above the work surface.

Abstract: An electro-permanent magnet key assembly may comprise an electro-permanent magnet generating a magnetic field when a direction of current applied to an electrically conductive wire coiled around a low-coercivity magnet, and a pair of scissor plates operably connected to the electropermanent magnet, such that the scissor plates rotate away from one another in the presence of downward force on a key cap situated atop the scissor plates. The top surface of the key cap may lie flush with adjacent keys of a keyboard when the key cap is in a neutral position. The electro-permanent magnet key assembly may further comprise a ferromagnetic flange operably connected to one of the scissor plates having angled overlap protrusions situated adjacent to the electropermanent magnet when the key cap is not in the neutral position, such that the angled overlap protrusions are attracted toward the magnetic field to return the key cap to the neutral position.

Abstract: A display cover can include a rectangular body having opposing outer and inner surfaces and an edge that connects the outer and inner surfaces. A central region, widthwise edge regions, and lengthwise edge regions can each define a portion of the outer and inner surfaces, and the edge regions each can extend from the central region to define a portion of the edge. The central region can be planar such that a plane lies between the outer and inner surfaces throughout the central region. Each of the widthwise edge regions can curve away from the central region such that a line that is tangent to the outer surface at the edge region is substantially perpendicular to the plane of the central region. The body's average thickness can be less than or equal to 0.5 mm, and the body can comprise at least a majority, by weight, of a polymeric material.

Abstract: A dual axis hinge assembly couples first and second hinges to each other with a central barrel and routes cables across hinge axles with cable channels formed in the axles. The dual axis hinge assembly rotationally couples information handling system housing portions to each other and routes cables between the housing portions distal the barrel by running the cables through a channel formed in each axle of one of the hinges with the cable entering one axle distal the barrel, routing through the axle to a position proximate the barrel, crossing the hinge to enter the other hinge axle proximate the barrel and routing though the other axle to exit distal the barrel.

Abstract: A dual-contact electro-permanent magnet (EPM) assembly of an information handling system may comprise a plurality of high-coercivity magnets situated on opposite ends of a low-coercivity magnet, a first EPM magnetic contact disposed between a first of the plurality of high-coercivity magnets and the low-coercivity magnet, and a second EPM magnetic contact disposed between a second of the plurality of high-coercivity magnets and the low-coercivity magnet. The low-coercivity magnet polarity may correlate to a direction of current pulse applied to an electrically conductive wire coiled around the low-coercivity magnet, and dependent upon the low-coercivity magnet polarity, the first EPM magnetic contact is capable of operating in an attractive magnetic state to attract a ferromagnetic contact of a peripheral device while the second EPM magnetic contact is magnetically neutral with respect to the ferromagnetic contact.

Abstract: A variable torque opening hinge joint for a laptop may comprise a shaft having a protrusion along its axial length and operably connecting to a display chassis inserted through a first hinge joint and a second hinge joint that are operably connected to a base chassis. The first hinge joint may apply a constant torque resistive to a rotation of the shaft throughout a range of angular displacement, and the second hinge joint may apply a variable torque resistive to a rotation of the shaft that increases from a minimum variable resistive torque to a maximum variable resistive torque over a preset subset of the range of angular displacement to reach a maximum variable torque. A leading edge of the protrusion and a trailing edge of the protrusion may be separated by an angle equivalent to the preset subset of the range of angular displacement.

A display cable manager regulates a length of the display cable by wrapping the display cable about a spool biased to retract the display cable.

Abstract: A portable information handling system transformation between clamshell and all-in-one configurations is managed by a position manager that senses main and display housing positions to restrict configuration actions if predetermined conditions are detected. For example, transformation to an all-in-one configuration may be restricted if display housing location and rotational orientation are not set before extension of a stand that raises the main housing rear surface.

Abstract: A portable information handling system transforms from a clamshell configuration to an all-in-one configuration by removing a keyboard from a main housing, sliding the display housing in a guide formed under the keyboard and raising a rear side of the main housing to elevate the display. A brake interfaces with the display housing through the guide to lock the display at variable heights. A brake release selectively releases the brake to allow display height adjustment by adjusting the relative position of the display housing at the main housing.

Abstract: A portable information handling system transforms between clamshell and all-in-one positions by sliding a display housing pivot axis towards a front side of a main housing and raising the rear side of the main housing with a stand that extends out from a bottom surface of the main housing. A keyboard detaches from the main housing upper surface to expose guides that manage the display housing sliding motion towards the main housing front side. The all-in-one position raises the main housing towards a near-vertical orientation to raise the display above a support surface for end user viewing while an end user interacts with the keyboard separated from the housing.

Abstract: An information handling system hinge provides friction against rotational motion to generate torque that regulates housing portion relative position. Friction is generated by compression of friction elements with a super elastic wire under tension. For example, a nickel titanium alloy wire under two to eight percent strain provides a relatively low spring rate having consistent compression even as wear reduces the size of the friction elements.

Abstract: A portable information handling system stand couples to a main housing lower surface with a dual axle hidden stand hinge that extends the stand parallel to the main housing lower surface with an initial synchronized opposing rotation of the axles by a predetermined amount, such as 45 degrees, and then rotates out a stand supporting end with rotation of one axle while the other axle remains stationary. Initial parallel extension of the stand reduces the amount of space in the main housing lower surface consumed by rotational movement of the stand to an extended position.
