Abstract: An input device includes transmitter electrodes disposed in a sensing region of the input device, a receiver electrode in the sensing region, and a processing system. The processing system includes demodulators and is configured to simultaneously drive at least a subset of the transmitter electrodes using a multitude of transmitter signals with unique frequencies. The processing system is also configured to receive, on the receiver electrode, a resulting signal, and demodulate, using the plurality of demodulators, the resulting signal to generate a multitude, of sensing signals.

Abstract: A display driver includes image processing circuitry and drive circuitry. The image processing circuitry is configured to receive a foveal image, a full frame image, and coordinate data that specifies a position of the foveal image in the full frame image. The image processing circuitry is further configured to render a resulting image based on the full frame image independently of the foveal image in response to detection of a data error within the coordinate data. The drive circuitry is configured to drive a display panel based on the resulting image.

Abstract: A system includes a logic device configured to cause the system to perform operations. The operations include requesting, from a peripheral device coupled to a host device, a device descriptor of the peripheral device, receiving, from the peripheral device, the device descriptor including at least two configurations. A first configuration includes an audio communications protocol having a plurality of selectable audio bit-rates and a second configuration including a plurality of selectable audio bit-rates and burst-rates. The operations further include selecting, from the first configuration and the second configuration based, at least in part, on a configuration of the host device, wherein the host device is configured to select the second configuration when the host device is compatible with the second configuration and select the first configuration when the host device is not compatible with the second configuration.

Abstract: A device includes a display and a first light source configured to emit light, wherein the first light source is proximate to the display. The device further includes a first camera disposed behind the display, wherein the first camera is configured to detect reflections of the light emitted by the first light source. The first camera is further configured to capture a first image based at least in part on the reflections, wherein the reflections are partially occluded by the display. The device also includes a second camera proximate to the display, wherein the second camera is configured to capture a second image. In addition, the device includes a depth map generator configured to generate depth information about one or more objects in a field-of-view (FOV) of the first and second cameras based at least in part on the first and second images.

Abstract: A method and apparatus for device personalization. A device is configured to receive first sensor data from one or more sensors, detect biometric information in the first sensor data, encode the biometric information as a first vector using one or more neural network models stored on the device, and configure a user interface of the device based at least in part on the first vector. For example, the profile information may include configurations, settings, preferences, or content to be displayed or rendered via the user interface. In some implementations, the first sensor data may comprise an image of a scene and the biometric information may comprise one or more facial features of a user in the scene.

Abstract: Embodiments herein provide a dual optical and capacitance sensor. During a first time period, the dual sensor uses optical sensing to capture a fingerprint (e.g., to identify or verify the fingerprint). During a second time period, the dual sensor uses one or more capacitive sensor electrodes to perform capacitive sensing. The capacitive sensing may be absolute capacitive sensing or transcapacitive sensing.

Abstract: A system and method for encoding, transmitting and updating a display based on demura calibration information for a display device comprises generating demura correction coefficients based on display color information, separating coherent components from the demura correction coefficients to generate residual information, and encode the residual information using a first encoding technique. Further, the image data may be divided into data streams, compressed and transmitted to from a host device to a display driver of a display device. The display driver decompresses and drives subpixels of the pixels in based on the decompressed data. The display driver updates the subpixels of a display using corrected greyscale values for each subpixel are determined from the decompressed data.
