Abstract: A liquid lens includes a substrate, a transparent elastic membrane forming a cavity with the substrate, and a transparent fluid filling the cavity between the substrate and the membrane. The membrane has a pre-distorted, rotationally asymmetric shape in absence of the fluid in the cavity. When the cavity is filled with the fluid and the substrate is disposed vertically w.r.t. gravity at a pre-defined clocking angle, the membrane adopts a substantially rotationally symmetric shape due to elasticity of the membrane counteracting gravity exerting a downward force on the fluid in the cavity, reducing the effect of the gravity sag on optical performance of the liquid lens.

Abstract: The present disclosure relates to systems and methods for defining and modifying behavior in an extended reality environment. The systems and methods include receiving a request to build or modify a rule or policy for a given user or activity, obtaining a template based on the user or the activity, displaying the template and tools for editing the template, receiving a modification to the template via the user interacting with the tools of the user interface, and modifying the template based on the modification to generate the rule or policy. The modification includes changing the initial value for the actions or the conditions of the template and saving the template as a separate instance representative of the rule or policy, and the rule or policy includes one or more conditional statements for executing one or more of the actions based on evaluation of one or more of the conditions.

Abstract: A method includes assessing a semantic-based query for a user that includes user goals and assessing probability values and first goal probability values, both of which are associated with active digital actions. The method includes generating a decision engine to determine a user friction value and second goal probability values associated with the user goals using the first goal probability values and the probability values. Further, the method includes determining the user friction value and the second goal probability values using the first goal probability values and the probability values. Moreover, the method includes determining a plan of digital actions based on the user friction value, the second goal probability values, and the user goals. Furthermore, the method includes, in response to determining the user friction value exceeds a predetermined threshold, generating a query to adjust the active digital actions based on the semantic-based query for the user.

Abstract: An audio system comprises a plurality of membranes within an enclosure. A first surface of each of the plurality of membranes is part of a shared back volume within the enclosure and pressure within the shared back volume is configured to be isobaric. A second surface of each of the membranes is part of a front volume within the enclosure that includes a plurality of ports. A controller of the audio system is configured to drive the plurality of membranes. In a mode of operation, the controller is configured to match audio output between the plurality of ports, forming pressure waves of equal amplitude and opposite phase and generating a substantially dipole or linear quadrupole sound wave radiation pattern for frequencies above a predefined threshold and mismatch audio output between the plurality of ports for frequencies at or below the predefined threshold to generate a substantially monopole or cardioid sound wave radiation pattern.

Abstract: A method for training a three-dimensional model face animation model from speech, is provided. The method includes determining a first correlation value for a facial feature based on an audio waveform from a first subject, generating a first mesh for a lower portion of a human face, based on the facial feature and the first correlation value, updating the first correlation value when a difference between the first mesh and a ground truth image of the first subject is greater than a pre-selected threshold, and providing a three-dimensional model of the human face animated by speech to an immersive reality application accessed by a client device based on the difference between the first mesh and the ground truth image of the first subject. A non-transitory, computer-readable medium storing instructions to cause a system to perform the above method, and the system, are also provided.

Abstract: Methods of interpreting in-air hand gestures based on orientations of a wrist-wearable device are provided. The method includes receiving, from sensors of a wrist-wearable device, data associated with performance of an in-air hand gesture during a first period of time. The method includes, when determining the data indicates that the wrist-wearable device had a first orientation when the in-air hand gesture was performed during the first period of time, causing performance of a first operation. The method includes receiving, from sensors of the wrist-wearable device, new data associated with performance of the in-air hand gesture during a second period of time, the second period of time being after the first period of time. The method includes, when determining that the new data indicates that the wrist-wearable device had a second orientation when the in-air hand gesture was performed during the second period of time, causing performance of a second operation.

Abstract: A headset includes a thermal frame disposed within a housing. A printed circuit board (PCB) is thermally coupled to the thermal frame. Heat generated by one or more electrical components on the PCB is transmitted to the thermal frame, which distributes the heat uniformly throughout the headset. A first heat pipe is disposed on a first side of the PCB in contact with at least a portion of the thermal frame, the PCB, and/or an electrical component disposed on the PCB to draw heat from the electrical component, and a second heat pipe is disposed proximate a second side of the PCB and is configured to draw heat from second side of the PCB.

Abstract: In one embodiment, a computing may display an artificial reality environment to a user wearing an artificial reality device. The artificial reality environment may include at least a first virtual object. The computing system may monitor a motion of a first gesture performed by the user when interacting with the first virtual object. The computing system may determine, using a motion-stabilization profile of the user, a motional range associated with the user. The computing system may compare the motion of the first gesture performed by the user with the motional range associated with the user. The computing system may stabilize one or more second gestures performed by the user during subsequent user interactions in the artificial reality environment responsive to determining that the motion of the first gesture performed by the user exceeds the motional range.

Abstract: A micro-light emitting diode (micro-LED) device includes semiconductor mesa structures, and waveguides and grating couplers in regions of a semiconductor layer between the semiconductor mesa structures. At least some light emitted in the active region of each semiconductor mesa structure can be coupled into and guided by a waveguide towards a grating coupler. The grating coupler is configured to diffract the guided light out of the micro-LED device, for example, in a direction substantially perpendicular to the light-emitting surface of the micro-LED device, through regions between the semiconductor mesa structures.
