Abstract: An information handling system having rotationally coupled housing portions supports a flexible display disposed across the housing portions with a hinge structure that manages flexible display curve radius in a folded configuration. A set of plural hinges having five geared rotational portions interconnect with a bar fixedly coupled to the center hinge rotational portion. The bar presses against a shape memory alloy support that manages curve radius of a flexible display during rotation of the hinges.

Abstract: Detection and tracking of a totem by a touchscreen touch controller mitigates false touches and false inputs by adapting capacitance at the totem feet. Totem feet have a capacitance that falls between a noise threshold and a finger touch threshold so that a pattern of the totem feet is detected separate from finger touches. Active capacitance is applied to one or more of the totem feet to enhance totem detection, such as by highlighting totem contact points of interest to an end user for a rotational versus linear input.

Abstract: A rotating body, such as ball, disposed in a totem is selectively engaged and disengaged by a friction element to selectively restrict or allow motion of the totem on a touchscreen display. Engagement of the rotating body maintains a totem position on a touchscreen display, such as to support rotational inputs associated with a rotational user interface or to prevent the totem from sliding off the touchscreen display in response to tilting of the touchscreen display. Disengagement of the rotating body releases the totem to slide across the touchscreen display, such as to make inputs at a linear user interface.

Abstract: A portable information handling system transfers thermal energy associated with operation of processing components in a main housing portion through a graphite torsion spring formed from a graphite sheet by cutting arms to extend out of opposing corners of a central portion and rolling the central portion about a central axis. The graphite torsion spring passes thermal energy between the housing portions with the spring releasing tension as the housing portions rotate from a closed to an open position and the central axis disposed about a hinge pin that couples the housing portions to each other.

Abstract: A portable information handling system transfers thermal energy associated with operation of processing components between rotationally coupled housing portions through a thermal spreader disposed between the housing portions, such as a sheet having one or more layers of graphite. A tensioning assembly engages the thermal sheet to manage excess material associated with varying rotational orientations of the housing portions.

Abstract: An information handling system narrow width dual axes hinge rotationally couples portable information handling system housing portions to each other with minimal spacing between the housing portions. A gear assembly synchronizes motion about the dual axles at one end of the dual axles, the gear assembly having brackets to couple to each housing portion. Torque brackets couple to the opposite end of the dual axles, each torque bracket couple to a housing portion and resisting rotation of the housing portions by generating friction at the axle.

Abstract: A totem object placed on a touchscreen display provides inputs based upon touches made at the touchscreen display, such as with the rotational orientation or linear location of the totem object relative to a user interface presented outside the totem object. A visual access from the touchscreen display through the totem object passes a visual image from the touchscreen display for presentation at the totem object upper surface, such a numerical value of an input made by totem object position on the touchscreen display.

Abstract: A totem resting on a touchscreen display integrates a display at an upper surface to present visual information to an end user. Totem orientation is determined from totem touches at the touchscreen display and applied with other factors to orient the presentation of visual information at the totem to the orientation of an end user viewing the touchscreen display. Visual information presented at the totem may include input icons to associate the totem with an application, notifications from applications, and content presented at the touchscreen display under the totem.

Abstract: A portable information handling system transfers thermal energy associated with operation of processing components in a first housing portion to a thermal exchanger in a second housing portion through a hinge that rotationally couples the first and second housing portions. The hinge has first and second axles that each define a channel. Fluid heated at the first housing portion passes through the channel to the thermal exchanger where thermal energy is rejected from the system. In one embodiment, a second hinge having first and second axles that each define a channel provides a return path for the fluid from the second housing portion to the first housing portion.

Abstract: A portable information handling system transfers thermal energy associated with operation of processing components in a main housing portion to a vapor chamber integrated in a lid housing portion that distributes the thermal energy across the lid housing portion. A hinge protrusion formed in the lid housing portion defines a cylindrical opening that accepts a hinge pin to rotationally couple the housing portions to each other. The cylindrical wall defines a barrier with the vapor chamber so that a thermal conduit passing from the main housing portion to the hinge pin transfers thermal energy from the hinge pin through the cylindrical wall to the vapor chamber.

Abstract: A portable information handling system transfers thermal energy associated with operation of a CPU to a location distal the CPU with a vapor chamber thermally interfaced with the CPU. A pressure adapter interfaced with the vapor chamber selectively changes the pressure within the vapor chamber to adjust the saturation point of a liquid in the vapor chamber that manages thermal transfer efficiency. For example, a controller interfaced with the pressure adapter modifies thermal transfer characteristics of the vapor chamber to control thermal conditions at the information handling system, such as in response to a temperature sensed at a housing surface, a battery, a display or at other locations of the information handling system.

Abstract: A portable information handling system transfers thermal energy associated with operation of a CPU from a main housing portion to a lid housing portion with thermal conduction through a hinge assembly that rotationally couples the main and lid housing portions to each other. For example, thermal conduits insert into a hinge body and transfer thermal energy across the hinge body through a thermally conductive interface, such as the hinge body itself, thermal grease disposed in the hinge body, a liquid that fills a cavity of the hinge body shared by the thermal conduits, and a vapor chamber integrated in the hinge body.

Abstract: An information handling system having rotationally coupled housing portions supports a flexible display disposed across the housing portions with a hinge structure that manages flexible display curve radius in a folded configuration. A dual axis synchronized hinge defines the flexible display bend radius by the distance between the hinge axes and by a shape memory alloy planar support fixed in position relative to the hinge. A ramp structure engages a flexible display frame during rotation to an open position to maintain the display frame in a planar configuration.

Abstract: An information handling system having rotationally coupled housing portions supports a flexible display disposed across the housing portions with a hinge structure that manages flexible display curve radius in a folded configuration. The hinge includes plural hinge elements having an arc face, arc cavity interior and mounts that couple with hinge coupling elements. The mounts align the hinge coupling element rotational axis out of the cavity to aid in maintaining the hinge elements having no gaps during rotation of the information handling system housing portions. The hinge coupling element integrates friction plates disposed normal the rotation axis to generate torque for managing housing rotational movement.
