  • Patent number: 10630810
    Abstract: Systems and methods for communications between Head-Mounted Devices (HMDs) in virtual, augmented, and mixed reality (xR) applications are described. In an illustrative, non-limiting embodiment, a first HMD may include a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution, cause the first HMD to: during execution of an xR application, maintain a receive (Rx) channel with a second HMD, as part of a communication session, using a first transport; and maintain a transmit (Tx) channel with the second HMD, concurrently with the Rx channel and as part of the communication session, using a second transport different from the first transport.

  • Patent number: 10620679
    Abstract: A power storage adapter (PSA) may be connected to multiple battery-powered devices. A PSA controller may be configured to receive respective requests to supply electrical power to a first device and a second device, to determine that the power storage adapter does not have sufficient power supply capacity to satisfy both requests, to determine that a respective state of charge (SOC) of at least one device battery is below a first battery SOC threshold, and to prioritize supplying electrical power to a selected one of the devices at the expense of the other device based on a battery charging prioritization policy. The selected device may be prioritized until the battery SOC exceeds a battery SOC threshold or for a predetermined time period. The battery charging prioritization policy may specify relative charging priorities for the device batteries and a PSA battery dependent on whether AC line power is available.

  • Patent number: 10599381
    Abstract: In a collaborative virtual, augmented, and mixed reality (xR) session, different users wearing head-mounted devices HMDs may leave the xR session and new HMD-wearing users may join. The HMD worn by the joining user may be calibrated based on the physical characteristics, such as ambient noise and interference, of physical environment in which the xR session is conducted. An HMD may generate a profile of the noise and interference in the environment that adversely affects the ability for the communicating directly via supported transmission mechanisms. The profile may be provided directly to the joining HMD, allowing the joining HMD to quickly calibrate the transmission mechanisms included in the received profile to the particular sources of noise and interference in the physical environment.

  • Patent number: 10581940
    Abstract: Methods and systems are provided for collaborating in the discovery of Head-Mounted Devices (HMDs) configured for hosting a co-located virtual, augmented, or mixed reality (xR) session. An HMD issues a request to join a co-located xR session. Participating in a co-located xR session requires a joining HMD to obtain authorization from a host HMD. A joining HMD may be located such that direct communications between the joining HMD and the host HMD are either unreliable, or beyond the capabilities of two HMDs. The joining HMD may collaborate with neighboring HMDs to obtain authorization from a host HMD. The host HMD aggregates information from joining HMDs to determine the authorized HMDs and to determine the most reliable forms of direct communication between each pair of HMDs participating in the xR session.

  • Publication number: 20190332154
    Abstract: Systems and methods employ an external energy storage device (e.g., intelligent battery pack) interposed between a an information handling system (IHS) and its AC-to-DC adapter. The information handling system may be a fixed compute system, may lack an internal battery and/or may execute an operating system that does not have power management capability. The external energy storage device provides power and power state information to the IHS, e.g., that is based on state of charge (SOC) of the battery and/or absence/presence of AC power. IHS may perform one or more actions based on the power state information such as automatically save data and shutdown when notified AC power is lost and/or SOC is low, and may automatically restart and restore saved data when notified AC power is restored and/or SOC is sufficiently high. The external energy storage device may actively signal or command the IHS to act or may passively supply power state information and let the IHS decide how to act.

  • Publication number: 20190324509
    Abstract: In one or more embodiments, one or more systems, processes, and/or methods may determine that an external power supply coupling is coupled to an information handling system (IHS); may determine that power is not being received via the external power supply coupling; may, after determining that determining that power is not being received via the external power supply coupling, determine that a battery power supply of the IHS is able to power the IHS; may determine that a user is not present; may save a state of the IHS to a non-volatile memory medium; and may power down the IHS. In one or more embodiments, the one or more systems, processes, and/or methods may further receive power via the external power supply coupling; may power up the IHS; and may restore the state of the IHS from the non-volatile memory medium.

  • Patent number: 10228848
    Abstract: Projected input and output devices adapt to a desktop environment by sensing objects at the desktop environment and altering projected light in response to the sensed objects. For instance, projection of input and output devices is altered to limit illumination against and end user's hands or other objects disposed at a projection surface. End user hand positions and motions are detected to provide gesture support for adapting a projection work space, and configurations of projected devices are stored so that an end user can rapidly recreate a projected desktop. A projector scan adjusts to limit traces across inactive portions of the display surface and to increase traces at predetermined areas, such as video windows.

  • Publication number: 20190074708
    Abstract: A power adapter device may use a method for efficient charging of multiple portable information handling systems based on learned charging characteristics. In particular, when electrical power is delivered to at least one of the portable information handling systems, the power adapter device may prioritize electrical power delivery to another portable information handling system ahead of the portable information handling systems based on the learned charging characteristics such that charging is efficient.

  • Patent number: 10209789
    Abstract: In some examples, a computing device may authenticate a user. The user may pair a stylus with the computing device. The stylus may include one or more buttons. After the user performs a first sequence of button presses using the buttons of the stylus, the computing device may receive a first instruction that causes the computing device to begin execution of an application. The application may receive input in response to the user manipulating the stylus on a touchscreen of the computing device. After the user performs a second sequence of button presses using the buttons of the stylus, the computing device may receive a second instruction that causes the computing device to save the input. The computing device may provide the user with access to the saved input in accordance with an access level associated with the stylus.
