Abstract: A portable information handling system supports a flexible OLED display film over housing portions rotationally coupled by a hinge by folding the OLED display film over the hinge. Hinge brackets that couple to the housing portions each have a gear member with a semicircular shape gear inner circumference that engages a gear subassembly of the hinge main body. Hinge bracket rotation translates through the gear subassembly for synchronized housing rotation. The hinge main body has first and second semicircular portions with a smooth surface defined to accept the outer circumference smooth surface of the gear member semicircular shape at first and second rotation axes about which the hinge brackets pivot so that the display film has space to fold in the closed position.

Abstract: A portable information handling system rotationally couples housing portions with a variable torque hinge having a first axle that rotates with a first housing portion, a second axle that rotates with a second housing portion and a synchronizing gear assembly that translates rotation between the first and second axles. Variable torque is applied by selectively engaging and disengaging a coupler gear with the synchronizing gear assembly to apply and remove an increased torque that resists housing rotation. In one embodiment, the coupler gear is an idler gear of the synchronizing gear mechanism that selectively applies and removes an increase torque of the second axle to the first axle. The coupler gear slides in response to an actuator, such as an electro-permanent magnet acting on a ferromagnetic material with high and low magnetic attraction states.

Abstract: A portable information handling system pivots a hinge rotational axis as the hinge rotates housing portions between open and closed positions to manage a gap between the housing portions. For example, the hinge couples a base at a perimeter of one housing portion, the base having a many body that slides on sliding members of the base and that supports a bracket extending inward to couple to another housing portion. A bracket gear engages with a pinion gear included in the main body to translate bracket rotation through the pinion gear to a rack integrated in the base, thereby sliding the main body relative to the base as the housing portions rotate so that the distance between the housing portions adjusts with rotational orientation.

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 game controller has first and second controller housings having an attachment guide structure that detachably couples to an attachment tab structure disposed on opposing sides of an information handling system and a bridge. Input devices of the controller housing communicate directly with the information handling system through opposing pins and pads disposed in the attachment features or indirectly by communicating with the bridge through opposing pins and pads so the bridge communicates with the information handling system. The attachment guide structure has opposing lips with plural slots that pass tabs of the attachment tab structure through so that a sliding motion engages the tabs behind the lips.

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.
