  • Patent number: 11755081
    Abstract: Systems and methods that may be implemented to provide supplemental cooling air for a portable information handling system from one or more mechanically-adjustable cooling air supply outlets that may be positioned and/or repositioned at multiple different locations relative to a portable information handling system, such as notebook computer or laptop computer. In one example, the disclosed systems and methods may be implemented to have one or more mechanically-adjustable cooling air supply outlets that may be positioned and/or repositioned to align with differing geometries of cooling air inlet opening locations that correspond to different portable information handling system sizes and/or designs.

  • Patent number: 11342103
    Abstract: De-magnetization protection is provided for electro-permanent magnets during information handling system manufacture and use by monitoring thermal conditions at the information handling systems to detect a thermal state associated with de-magnetization and commanding the electro-permanent magnets to an off state so that both magnets in the electro-permanent magnet have opposing polarities. The opposing polarities tend to stabilize magnet polarity to prevent de-magnetization during increased temperatures. Normal operations are then re-enabled once temperatures decrease.

  • Patent number: 10862482
    Abstract: An electro-permanent magnet (EPM) key assembly of an information handling system may comprise a pair of scissor plates operably connected to a base contact assembly including an EPM such that each of the pair of scissor plates may rotate away from one another in the presence of downward force on a key cap situated atop the pair of scissor plates for actuation of the EPM key assembly; the EPM comprising a low-coercivity magnet and a high-coercivity magnet; wherein an application of a first current pulse applied to an electrically conductive wire coiled around the low-coercivity magnet places the EPM in a first on state to assert a first magnetic field on a ferromagnetic flange operatively coupled to rotate with at least one scissor plate about a hinge; and wherein an application of a second current pulse applied to the electrically conductive wire places the EPM in a second on state to increase the magnetic field on the ferromagnetic flange.

  • Patent number: 10819341
    Abstract: Systems and methods are disclosed that may be implemented to indicate real time availability of individual key assemblies for user input to an information handling system. In one embodiment, the disclosed systems and methods may be implemented to retract an individual key assembly of a user input device (e.g., such as keyboard matrix, game controller, game pad, computer mouse, etc.) when the key assembly is, or becomes, unavailable for input to a user application (e.g., such as a computer game) that is executing on a host programmable integrated circuit (e.g., such as host CPU) of an information handling system. Such a retracted key assembly may then be extended when it becomes available for input to the user application.

  • Patent number: 10797699
    Abstract: An electro-permanent magnet (EPM) key assembly of an information handling system may include an electro-permanent magnet (EPM) that may include a low-coercivity magnet and a high-coercivity magnet and a magnetic field sensor to detect the magnitude of the magnetic field of the EPM; and a calibration module to calibrate the magnitude of the magnetic field of the EPM by receiving a sensed magnitude value of the magnetic field of the EPM and adjusting the magnitude value of the magnetic field of the EPM when that magnitude value deviates from an established value by a threshold amount.

  • Patent number: 10574233
    Abstract: Key assemblies are disclosed herein that are retractable and/or that present a variable key assembly depression force to a user. In one example, one or more key assemblies may be provided that each employ one or more electro-permanent magnets (EPMs) together with permanent magnet and/or magnetically permeable (e.g., ferromagnetic) key assembly components to control key retraction and extension, and/or to control peak depression force (e.g., typing force) required to depress and displace a key assembly from an extended position to a lower position that causes the key assembly to produce a digital or analog output signal.

  • Patent number: 10481656
    Abstract: Systems and methods that may be implemented using an external cooling dock that is configured to provide supplemental cooling to a portable information handling system by blowing sub-ambient temperature air into one or more existing external air intake-vents of the chassis of the portable information handling system. The external cooling dock may be further configured to electronically dock or otherwise mate in bidirectional signal communication with the portable information handing system to allow the cooling dock processing device to operate cooperatively in a closed loop with the internal processing device/s of the portable information handling system so as to control operation of the cooling dock components and/or the operation of the processing devices within the portable information handling system.
