  • 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: 12028659
    Abstract: An information handling system camera detects ambient light and applies ambient light brightness to determine whether to color correct a captured image with ambient color temperature or a color temperature associated with a display. For example, a first RGB ambient light sensor detects ambient light from the camera field of view. When the ambient light is below a predetermined brightness, the camera image sensor processor (ISP) applies color temperature of a second RGB ambient light sensor directed at a display to perform color correction. For instance, with camera that mounts on a display top side, the second RGB ambient light sensor is disposed at the bottom of the camera and directed at the display.

  • Patent number: 11968052
    Abstract: An information handling system communicates with external devices, such as a docking station, through a multi-protocol streaming cable, such as USB 3.0 (or greater) cable having a USB data protocol, a DisplayPort graphics protocol and a power transfer protocol. Upon detection of excessive errors at the cable, the multi-protocol stream is adjusted to maintain errors within an acceptable range and prioritize information transferred through one of the protocols. Adjustments may include changes to the number of data lanes assigned to each protocol, changes to the rate at which information is transferred with each protocol and changes to power transfer.

  • Publication number: 20240106970
    Abstract: An information handling system peripheral camera analyzes captured visual images to detect a face and analyzes the face to determine an upright orientation. Based upon the face upright orientation, the camera defines a visual image orientation to communicate the visual image from the peripheral camera to an information handling system so that the face is communicated in an upright orientation for use in a video conference, such as with an indication of a landscape or portrait image orientation. In one embodiment, an information handling system can perform the face upright orientation analysis and command a camera orientation to the camera so that visual images of the camera are communicated in alignment with the face upright orientation.

  • Patent number: 11943712
    Abstract: An information handling system wirelessly interfaces with plural peripheral devices, such as a keyboard or mouse, through primary radios that have a communication protocol, such as Bluetooth Low Energy or a wireless local area network. Secondary radios interface with their associated primary radio to provide a low power wake and sleep using wake and sleep signals sent between the secondary radios. An individual wake command is transmitted by a secondary radio to wake one peripheral or information handling system. A group wake command is transmitted by a secondary radio to wake plural peripherals and/or information handling system.

  • Publication number: 20240098212
    Abstract: Plural cameras cooperate to define an overlap of fields of view that consolidate to provide an extended field of view communicated to an information handling system. The plural cameras stitch the non-overlapping portions into a consolidated visual image by reference to a landmark captured by both cameras in the overlapping portion, such as a reference marker placed in the extended field of view. The plural cameras coordinate through a wireless interface or with a daisy chain of communication cables to share the overlap boundary, resolution compatibility and an architecture for communicating the consolidated field of view with the information handling system.

  • Publication number: 20240098501
    Abstract: An information handling system and peripheral mouse establish level four security when a preloaded security identification packet is available to securely identify both devices for the exchange of pairing information in a manner that avoids man-in-the-middle attacks. The peripheral advertises with both a BLE protocol packet that supports a conventional level 3 security pairing and a secure identification packet that supports a level four security pairing. When the secure identification packet advertisement is selected by a host, the BLE profile may be populated without performing pairing so that the profile can be used to subsequently pair without risk of a malicious device imitating the BLE interface.

  • Patent number: 11914795
    Abstract: An information handling system keyboard, or other type of input device, detects end user input presses with plural optical switches coupled to an aluminum plate. A magnetic field proximity sensor interfaced with the aluminum plate radiates a magnetic field through the aluminum plate to detect end user proximity based upon disruptions to the magnetic field. The optical switches power down their emitters when user absence is sensed and power up the emitters when the user presence is sensed. In alternative embodiments, the aluminum plate mounting of optical switches as described above may detect press inputs at mouse buttons or joystick triggers.

  • Patent number: 11893174
    Abstract: An information handling system mouse autonomously provides a rapid visual image transition from a first display to a second display in response to a predetermined condition detected at the mouse, such as a left click that an end user performs when on the visual image title bar accompanied by a gesture or a hot key input. The mouse responds to the inputs by commanding an acceleration of movement of the cursor coordinates so that the information handling system rapidly moves the visual image from the first display to the second. In various embodiments, the movement can include a selection to go to a full screen presentation or to keep the visual image size the same. The visual image transfer is performed without any coordination with the information handling system other than commanding cursor coordinate movements.
