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.

A wireless input/output (I/O) device wirelessly coupled to a wireless dongle of an information handling system to encrypt and transmit a data packet frame in response to a transmitted polling packet from a wireless dongle requesting a selected number of packets of a selected packet length. The microcontroller executing code instructions to sign and encrypt the selected number of data packets generating a signature and generating an LFSR distributed signature and an LFSR distributed payload. An encryption algorithm used with an initial or dynamic key and shifting state machine output of another pair of LFSRs generates a data packet encryption output value that is applied via an exclusive OR operator to the LFSR distributed signature and payload to encrypt the data packet and the data packet encryption output value is used for encryption of the next data packet until the selected number of packets of the frame are encrypted.

An information handling system selects applicable display partitions based on the properties of a display screen, and determines a preferred window size of an application. The system adjusts a target zone of a window of the application based on the preferred window size.

Adaptive display screen partitioning

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.

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.

Information handling system headset with adjustable earcup position for stereo and mono audio presentation

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.

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.

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.

Information handling system multi-stream cable throughput management

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.

Information handling system and peripheral group wakeup radio interface synchronized communications

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.

An information handling system wirelessly interfaces with a location peripheral aid through primary radios that have a communication protocol, such as Bluetooth Low Energy or a wireless local area network, and through secondary radios having a low power wake and sleep using wake and sleep signals sent between the secondary radios. The location peripheral aid establishes communication with the information handling system, which reports its position to a network location to allow tracking location of the peripheral aid. The peripheral primary and secondary radio transmit and receive states operate with different profiles to manage power based upon bi-directional communications tracked over time.
