  • Publication number: 20180219553
    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.

  • Publication number: 20180219552
    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: 9959996
    Abstract: 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.

  • Patent number: 9791941
    Abstract: 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.

  • Publication number: 20170273214
    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: 9763021
    Abstract: Systems and methods are disclosed herein that may be implemented to use multiple light sources to visually display non-graphics positional audio information based on multi-channel audio information produced by a computer application executing on a processor of an information handling system. The multiple light sources may be operated separately and independently from a user's computer display device, and the non-graphics positional audio information may be separate and different from any visual graphics data that is generated by the computer application or information handling system.

  • Publication number: 20170168531
    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.

  • Patent number: 9665191
    Abstract: User input devices with variable pressure buttons are configured. A user may specify a range of pressure to be associated with a pressure level. In some embodiments, a user may also associate a command or other instruction to an application with an identity of a variable pressure button and a pressure level of the button. In some embodiments, the associations may be represented in a configuration profile. In further embodiments, a microcontroller for a mouse may translate signals from variable pressure buttons into pressure levels based upon the configuration file. In many embodiments, a user may associate a reporting rate with a variable pressure button. A legacy application may receive reports of the state of the variable pressure button at the associated reporting rate.

  • Patent number: 9343248
    Abstract: Systems and methods are disclosed that enable spring loaded mechanical key switch assemblies having variable displacement sensing capabilities. In one example, the disclosed key switch assemblies may be implemented in a keyboard system and used for providing variable displacement output signals that may be processed by a controller for input to a host processing device of an information handling system, such as a desktop or notebook computer. In another example, the disclosed key switch assemblies may be configured to provide both a digital “make” connection signal and separate variable displacement output signal/s that may be processed for input to a host processing device of an information handling system.

  • Patent number: 9342149
    Abstract: Systems and methods are employed for implementing haptics for pressure sensitive keyboards, such as the type of keyboards having keys that produce alternating digital open/short signals that emulate actuation of conventional “momentary on” digital keys. The disclosed systems and methods may be implemented to provide haptics for both touch typing and variable pressure sensitive operation of a pressure sensitive keyboard. Users of a variable pressure keyboard may be provided with a variable pressure haptics effect, e.g., to enable the user to intuitively understand from the haptics vibration produced by the key how much pressure they are applying to a given key at any given time. Vibration characteristics (e.g., vibration rate, vibration waveform pattern, etc.) of a given pressed key may be varied in real time in coordination with, or in response to, corresponding changes in user pressure applied to the same given key.
