Abstract: Some examples of the disclosure are directed to systems and methods for augmenting and/or minimizing environment audio based on video characteristics associated with a video communication session facilitated by a video communications application. The video characteristics include activation of an outward facing camera. In response to detecting the activation of an outward facing camera, an electronic device augments an environment audio stream associated with the video communication session and attenuates a first person audio stream associated with the video communication session such that the user listening to the audio stream hears audio that has the environmental audio emphasized while the first person audio is deemphasized. In response to detecting the activation of an inward facing camera, the device emphasizes the first person audio stream and deemphasizes the environmental audio stream.

Abstract: Embodiments herein provide various apparatuses and techniques to reduce flicker noise and voltage offset from the buffers and/or amplifiers while avoiding additional alias components in a sampled-data receiver with chopper stabilization. Additionally, a direct-conversion baseband chain may be improved by disposing alternating current (AC) coupling circuits between chopper circuits in the transmitter or receiver chain to enable selection of a distinct common-mode level at each stage of the direct-conversion chain, while reducing or eliminating signal loss at direct current (DC) frequencies.

Abstract: This disclosure is directed to a Voltage-Controlled Oscillator (VCO) with improved phase noise compared to other VCOs. The VCO may include a first cell and a second cell separated by common-mode (CM) isolation circuitry to reduce an amplitude of CM noise at an output signal. The CM isolation circuitry may inductively couple the first cell to the second cell for generating the output signal based on a resonant frequency range including resonant frequencies of the CM isolation circuitry, the first cell, and the second cell. As such, the first cell and the second cell may each include a portion of an entirety of the CM noise. In some cases, the portions of the CM noise on the first cell and/or the second cell may improve a signal to noise ratio of the output signal.

Abstract: Embodiments described herein include an optoelectronic sensing device having a vertical cavity surface emitting laser (VCSEL), a resonance cavity photodetector (RCPD), and a tunnel junction. The VCSEL is at least partly defined by a first set of semiconductor layers disposed on a substrate. The first set of semiconductor layers includes a first active region. The VCSEL is configured to emit laser light towards the substrate, upon application of a first bias voltage, and undergo self-mixing interference upon reception of reflections or backscatters thereof. The RCPD is vertically adjacent to the VCSEL and is at least partly defined by a second set of semiconductor layers disposed on the substrate. The second set of semiconductor layers includes a second active region. The RCPD is configured to detect, upon application of a second bias voltage, the self-mixing interference. The tunnel junction is disposed between the first active region and the second active region.

Abstract: Embodiments are disclosed for active cancellation of noise in motion sensor signals. In some embodiments, a method comprises: obtaining a motion sensor signal from a motion sensor; obtaining a reference signal indicative of parasitic vibration from a vibration source mechanically coupled to the motion sensor; generating, using an adaptive noise canceller, an estimate of the parasitic vibration; and using the estimated parasitic vibration to cancel the parasitic vibration from the motion sensor signal.

Abstract: Various implementations disclosed herein include devices, systems, and methods that present content items (e.g., movies, TV shows, home-made videos, etc.) on electronic devices such as HMDs. Some implementations adjust what is being displayed by the electronic devices to mitigate optical module-based artifacts (e.g., ghosting). For example, in an HMD with a catadioptric lens, a mirror layer may leak some light to produce ghosting artifacts that may be mitigated by adjusting brightness, dynamic range, contrast, light-spill, color, etc. Some implementations utilize adjustments that are based on content item awareness (e.g., adjustments based on the peak brightness of the scene in a movie that is being displayed within an extended reality (XR) environment, etc.). Some implementations provide adjustments based on environment awareness (e.g., how dark is the surroundings or pass-through environment) and/or optical module modeling. The adjustments may change a particular content item and/or an environment in which it is presented.

Abstract: Some examples of the disclosure are directed to systems and methods for displaying three-dimensional models of virtual three-dimensional environments. In some examples, the three-dimensional model includes representations of the virtual object(s) included in the environment, a representation of a viewpoint of a user of the electronic device in the environment, and a representation of a viewpoint of a second user of a different electronic device in the environment. In some examples, in response to receiving an input requesting to display the virtual three-dimensional environment (e.g., at full size), the electronic device displays the virtual three-dimensional environment from the viewpoint of the user of the electronic device indicated in the model.
