  • Publication number: 20250119677
    Abstract: A wireless headset includes a microcontroller and a first earpiece and a second earpiece to provide audio output to a user. The wireless headset includes a flexible headband coupled to the first earpiece and second earpiece and a headband profile state sensor. The headband profile state sensor detects when the headset is in a headset un-worn headband gesture state and a worn headband gesture state by detecting a change in resistance value at a headband profile state sensor when a distance between the earpieces is increased and decreased thereby flexing the headband. A headband state circuit includes a comparator to detect a change in the resistance at the headband profile state sensor. The headband state circuit may be dynamically adjusted via bias gain used to ensure the headband state circuit is able to detect transitions between the headset un-worn headband gesture state and the headset worn headband gesture state.

  • Patent number: 12212914
    Abstract: A headset presents audio sounds with first and second speakers disposed in first and second earcups that fit over first and second of an end user's ears. One ear cup adjusts with a greater travel distance relative to the other earcup so that the headset rests on the end user head with the one earcup raised above an ear and the other on an ear. A position sensor disposed in the headset detects the headset configuration to turn off audio at the speaker of the earcup that is displaced from the ear while increasing volume at the speaker of the earcup that remains over an ear. In addition, when only one ear is covered by an earcup, the audio presentation converts from stereo to monoaural.

  • Patent number: 12153740
    Abstract: Aspects of this disclosure implement at least one sensor in a user input device with an identifiable user input on an information handling system. A method may include receiving, by an information handling system, an indication that at least one sensor, located on an outward facing surface of a frame housing a user input device, is actuated; comparing, by the information handling system, the indication to an active profile configuration; and identifying, by the information handling system, the indication as an input based on the active profile configuration. Other aspects are also disclosed.

  • Patent number: 12075206
    Abstract: An information handling system presents audible sounds from audio information at an in-ear monitor having a speaker in a speaker housing that directs sound through a speaker tube. An angular alignment mechanism adjusts the angular orientation of the speaker tube relative to the speaker housing and a vertical alignment mechanism adjust the distance that the speaker tube extends out from the speaker housing. Position sensors detect the position of the ear tube so that an audio processor can apply the position to adjust the sound output from the speaker and the noise cancellation provided in response to external noise detected by a microphone within the speaker housing.

  • Publication number: 20240031715
    Abstract: A headset presents audio sounds with first and second speakers disposed in first and second earcups that fit over first and second of an end user's ears in an earcup orientation. A headband that couples to the earcups through straps adjusts the width between the earcups by extending and retracting the straps normal the orientation earcup orientation. In one embodiment, a rack and pinion assembly in the headband synchronizes strap movement to manage a balanced headset fit.

  • Patent number: 11822738
    Abstract: An information handling system mouse couples a precision scroll button located proximate a scroll wheel of the mouse upper surface to a multidirectional switch, such as a five-way switch, so that movement of the precision scroll button commands through the five-way switch a scroll up or down at a speed defined by the end user and independent of the scroll wheel speed. For instance, a fast scroll at different scroll rates is commanded by actuating the five-way switch forward or backwards.

  • Patent number: 11822737
    Abstract: An information handling system mouse couples a scroll wheel at a scroll wheel position of the mouse upper surface to a five-way switch so that movement of the scroll wheel commands through the five-way switch a scroll up or down, a swipe left or right and a press down mouse click. An adjacent button provides precision or fast scroll through an interaction separate from the scroll wheel. A vibration device interfaced with the scroll wheel provides haptic feedback of end user interactions, such as by providing vibrations with a vertical orientation from a position below the scroll wheel.

  • Patent number: 11316312
    Abstract: A mobile peripheral adapter rotationally couples first and second circular housings with a spindle to define and cable cavity. A cable retracts into and extends from the cable cavity by rotation of the housing portions to bring a cable connector into the cable cavity at an opening formed to align with the cable connector at retraction. First and second magnets disposed in the cable cavity retrain the cable connector when retracted. The opening at the bottom surface of the peripheral adapter reduces the vertical height of the cable cavity by providing vertical space within which the cable connector can reside.

  • Patent number: 11243619
    Abstract: An information handling system stylus makes inputs to a touchscreen display with a writing tip disposed at one end of a cylindrical housing. In an opening at the end of the cylindrical housing opposite the writing tip, a port and a push button are disposed under a removeable flexible cap to provide a cable connection for charging the stylus when the cap is removed and an input device to activate a wireless function when the flexible cap is in place, such as by translating end user pushes through a steel plate integrated in the flexible cap. An attachment member extends from the flexible cap into a sliding engagement with an end cap so that the flexible cap lifts out of the opening and flexes about the attachment member to expose the port in the opening.

  • Patent number: 11240438
    Abstract: An information handling system camera manages tilt and pan in an automated manner to direct the camera field of view. A shutter slides behind a camera cover to align a shutter opening with a cover opening. Additional sliding of the cover translates to a tilt of the camera from a full down axis to a full up axis. For example, a cam surface formed in the shutter engages the camera for tilt with a spring bias of the camera against the cam. Rotation of the camera housing about a bracket pivot gear is provided through sliding motion of a pan bar within the camera housing.
