  • Patent number: 11714761
    Abstract: A method and system configured to receive a first report from a computer peripheral device by a receiver, determine that the first report is corrupted or received at a rate slower than the first report rate, compute a current trajectory of the computer peripheral device based on one or more intervals of movement data in the first report, compute a predicted trajectory of the computer peripheral device based on the first report, compute an incremental displacement of the computer peripheral device based on the predicted trajectory. The method and system can further generate data indicative of a position or displacement of the computer peripheral device based on the predicted trajectory of the computer peripheral device and send the data indicative of a position or displacement of the computer peripheral device at an interval that is less than twice a period of the first report rate to the host computing device.

  • Patent number: 11711058
    Abstract: A microphone system includes a microphone and a pre-amplification conditioning circuit configured within a housing and comprising a pair of matched JFETs configured in a differential pair with common-source configuration and, when biased, are operable to receive and amplify the differential microphone output signal. The microphone further includes a pair of BJTs configured as a complimentary feedback transistor pair with each of the pair of BJTs coupled in parallel to a corresponding one of the pair of matched JFETs, and a current sink coupled to the matched JFETs and corresponding emitter electrodes of the BJTs and operable to maintain a fixed total direct current through each of the matched JFETs and BJTs, which reduces the JFETs corresponding electrical load, reduces signal noise, and increases a maximum amplified microphone output signal level at the drains of the matched JFETs.

  • Patent number: 11693475
    Abstract: Some embodiments include a method comprising receiving gaze data from an image sensor that indicates where a user is looking, determining a location that the user is directing their gaze on a display based on the gaze data, receiving a confirmation input from an input device, and generating and effectuating an input command based on the location on the display that the user is directing their gaze when the confirmation input is received. When a bystander is in a field-of-view of the image sensor, the method may further include limiting the input command to be generated and effectuated based solely on the location on the display that the user is directing their gaze and the confirmation input and actively excluding detected bystander gaze data from the generation of the input command.

  • Patent number: 11656668
    Abstract: A method is disclosed for synchronizing operating modes across a plurality of peripheral devices. The method includes each of the plurality of peripheral devices transmitting requests to change a rate of power consumption in response to a set of criteria for each peripheral device. A host computing device determines if one or more peripheral devices should change power modes and transmits corresponding commands to synchronize the plurality of peripheral devices into a single operating mode. Each peripheral device may have a unique power mode for a given operating mode and each peripheral device includes one or more common features, such as a lighting display, that is synchronized across all peripheral devices for a given operating mode.

  • Patent number: 11659133
    Abstract: Embodiments of the disclosure provided herein generally relate to methods and video system components that have integrated background differentiation capabilities that allow for background replacement and/or background modification. In some embodiments, undesired portions of video data generated in a video environment are separated from desired portions of the video data by taking advantage of the illumination and decay of the intensity of electromagnetic radiation, provided from an illuminator, over a distance. Due to the decay of intensity with distance, the electromagnetic radiation reflected from the undesired background has a lower intensity when received by the sensor than the electromagnetic radiation reflected from the desired foreground. The difference in the detected intensity at the one or more wavelengths can then be used to separate and/or modify the undesired background from the desired foreground for use in a video feed.

  • Patent number: 11644907
    Abstract: A method includes receiving sensor data from one or more sensors that corresponds to a location of a stylus device and determining that a tip of the stylus device is in contact with a physical surface based on the sensor data. While in contact, the method includes determining a new location of the tip of the stylus device based on the location data, mitigating a tracking error of the determined new location of the tip of the stylus device by translating the new location from a 3D space domain to a 2D space domain that corresponds to the physical surface and adjusting the new location based on a comparison of the new location and historical locations. The stylus device can further ascertain surface characteristics through sensor data and simulate surface characteristics via haptic feedback effects.
