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.

Mechanically-adjustable supplemental cooling systems and methods for portable information handling systems

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.

Electro-permanent magnet thermal protection

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.

System and method for controlling an electro-permanent magnet key switch assembly

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.

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.

Systems and methods for ultrasonic collision management in virtual, augmented, and mixed reality (xR) applications are described. In some embodiments, an Information Handling System (IHS) may include a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the IHS to: execute an xR application to display an xR image to a user of the IHS; and detect, via an ultrasonic sensor coupled to the processor, a potential physical interaction between the user and a physical object during execution of the xR application.

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.

Systems and methods are disclosed herein that may be implemented to configure, provide and operate retractable key assemblies and/or key assemblies that present a variable key assembly depression force to a user. In one example, 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.

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.

Systems and methods that may be implemented to orchestrate external graphics, for example to support and extend switchable graphics capability beyond internal system components of a host information handling system so as to include an external discrete graphics processing unit (xGPU) that is not integrated or embedded within the chassis enclosure of the host information handling system, and that is coupled to the host information handling system from outside the host system chassis enclosure.

Systems and methods for orchestrating external graphics

Systems and methods are disclosed that may be implemented to provide keycap lighting to a spring loaded mechanical key switch assembly using a light conductive structure, such as a light pipe, and without requiring a chassis housing of the mechanical key switch assembly to include a dedicated power-consuming light source mounted to or otherwise positioned at the location of the individual key switch assembly chassis housing. Additionally, the disclosed systems and methods may be implemented to use one or more common power-consuming light source/s to simultaneously provide key cap lighting to multiple such spring loaded mechanical key switch assemblies, for example, by feeding light to each key cap though a common light spreader and through an individual non-power consuming light pipe provided for each key switch assembly.

Systems and methods for lighting spring loaded mechanical key switches

Systems and methods are disclosed for user configurable pressure sensitive keys and techniques for controlling these keys for keyboards. User configuration information, including information for user configurable granularity scales for pressure levels, can be communicated from a host system to the keyboard and stored for later use by a keyboard controller to control the operation of the pressure sensitive keys. In this way, greater control of the pressure sensitive keys can be provided. This configurability is of particular use for applications such as where the keyboard is being used for gaming by a user running a gaming application on an information handling system.
