Abstract: A portable information handling system presents visual images at first and second displays integrated in first and second rotationally-coupled housing portions. When the housing portions rotate to a clamshell configuration, a keyboard disposed on one of the displays accepts keyed inputs and, to save power, backlight segments below the keyboard are powered down. The display can present information as visual images proximate the keyboard with illumination provided by other backlight segments or by a secondary light source that is presented in coordination with liquid crystal panel pixels transitioning to transparent and opaque states.

Abstract: A portable information handling system presents visual images at first and second displays integrated in first and second rotationally-coupled housing portions. When the housing portions rotate to a clamshell configuration, a refractive layer in a “DO” display aligns light illuminated from the display off an orthogonal angle and towards a user while a “SEE” display aligns light illuminated from the display along an orthogonal angle.

Abstract: A portable information handling system folds a flexible display over a hinge and selectively engages a stylus writing tip to make inputs at the flexible display based upon operating conditions of the flexible display. For instance, an information handling system communicates to a stylus a pressure constraint determined from current and historical operating conditions so that the stylus restricts excessive pressure from application to the display, such as by automatically selecting a writing tip with a greater surface area.

Abstract: Touchscreen computing device having support for interference-free operation of one or two active pens. A dedicated screen ID and pen ID establish a one-to-one pairing between an active pen and a touchscreen of a single-screen or dual-screen device, thereby rejecting interference from additional pens or screens. For a dual-screen device, the screen-specific uplink signals are synchronized using master-slave, interlaced timing to avoid mutual interference and to support simultaneous operation of two active pens—one on each screen. The downlink signals from two active pens occur during the same timeslots, whereas the two uplinks—one from each of the two screens—are interleaved with two timeslots for pen downlinks. Screen-specific screen ID-twin parameter is created for each screen of a dual-screen device to alert a pen to send its downlink signals in the interleaved manner.

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: An information handling system data port system includes plural data ports that support communication of data and power transfer with external devices, such as peripherals. A power transfer manager selectively establishes direct power transfer between data ports in support of power transfer between external devices, such as one external device acting as a power source and another external device acting as a power sink. The power transfer manager establishes direct power transfer with switches that bypass the information handling system power subsystem to provide improved power transfer efficiency.

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 a flexible display screen, first and second display platforms, and a rack gear component. The flexible display screen is movably mounted to the first and second display platforms. The rack gear component is mounted between the first and second display platforms, and controls support of the flexible display screen.

Abstract: A computing device may include a first housing attached to a second housing by one or more hinges. A second power transceiver in the second housing may receive power from a power source and wirelessly transmit the power to a first power transceiver in the first housing. The first power transceiver may distribute the power to a first display device and to a computer motherboard located in the first housing. The first power transceiver may include first magnets positioned to attract second magnets in the second power transceiver. Each power transceiver may include a bearing on either end that enables each power transceiver to rotate, such that a first coil of the first power transceiver is in a line of sight of a second coil of the second power transceiver, regardless of an orientation of the computing device.

Abstract: A portable information handling system selectively accepts power transferred from an external device through a port, such as USB Type C port, with one of a first or second power configuration. The first power configuration accepts power regulated by a charger of an external device and routed directly to a system bus and battery of the portable information handling system. The second power configuration accepts power regulated by an internal charger of the portable information handling system, such as a narrow voltage direct current charger.

Abstract: A computing device may include a first housing and a second housing attached by a hinge. A first data transceiver in the first housing may transmit signals, including a video signal, to a second data transceiver in the second housing. The second data transceiver may receive the signals and send the video signal to a display device in the second housing. Each data transceiver may include a frame on which is mounted a circuit board having an antenna, a set of magnets, and a pair of bearings on either end of the frame that enable each data transceiver to rotate. An attraction between the magnets of the first data transceiver and the magnets of the second data transceiver may cause one or both data transceivers to rotate, such that the antennas remain facing each other regardless of an orientation of the computing device.

Abstract: A computing device with a Broadband Intelligent Antenna System (BIAS) that supports a broadband antenna design within the device. Each broadband antenna operates over a plurality of Radio Frequency (RF) bands to cover multiple different wireless technologies with a single antenna. The BIAS may continually monitor multiple triggers capable of affecting the signal quality of the wideband antennas and may automatically switch the active antennas accordingly to select an operating configuration that provides a higher signal quality of the active antennas. Triggers may be generated when, for example, one or more antennas are being blocked by a user, there is a change in the orientation of the device, a source of electrical noise is detected, unacceptable Specific Absorption Rate (SAR) proximity is detected, and so on. The trigger-based adaptive switching from one active antenna to the other may substantially improve the overall signal quality for the multiple wireless technologies supported by the device.

Abstract: In some implementations a computing device may comprise at least a first display device and a second display device. The computing device may receive a selection to display protected content. The computing device may determine a display mode associated with the first display device and the second display device. The computing device may determine an orientation (e.g., landscape or portrait) and modify (e.g., by rotating) the content based on the orientation to create modified content. The computing device may determine a routing of the modified content and route the modified content to at least one of the first display device or the second display device.
