Abstract: Eyewear that includes a frame supporting an optical element. The frame has a first side and a second side. The eyewear also includes a temple adjacent the first side of the frame. The temple includes a first portion adjacent the frame and a second portion releasably connected to the first portion. The eyewear also includes an electrical connector embedded within the first portion of the temple. The second portion conceals the electrical connector from an exterior of the eyewear when the second portion connects to the first portion in a concealed state, and exposes the electrical connector from the exterior of the eyewear when disconnected from the first portion in an exposed state.

Abstract: Systems, methods, devices, computer readable media, and other various embodiments are described for location management processes in wearable electronic devices. Performance of such devices is improved with reduced time to first fix of location operations in conjunction with low-power operations. In one embodiment, low-power circuitry manages high-speed circuitry and location circuitry to provide location assistance data from the high-speed circuitry to the low-power circuitry automatically on initiation of location fix operations as the high-speed circuitry and location circuitry are booted from low-power states. In some embodiments, the high-speed circuitry is returned to a low-power state prior to completion of a location fix and after capture of content associated with initiation of the location fix. In some embodiments, high-speed circuitry is booted after completion of a location fix to update location data associated with content.

Abstract: Uploading of a video file is performed by transcoding, processing and uploading portions of the video file in parallel, to reduce total processing and upload time. The processing of the video file may include applying associated augmented reality effects to a raw video recording, to generate an enhanced video recording for transmission and viewing at a recipient device. The uploaded portions of the video file may be assembled into a fragmented file format such as fMP4, in which portions of the video file are stored as fragments.

Abstract: Methods and systems are disclosed for performing operations comprising: receiving a video that includes a depiction of a real-world object; generating a three-dimensional (3D) body mesh associated with the real-world object that tracks movement of the real-world object across frames of the video; determining UV positions of the real-world object depicted in the video to obtain pixel values associated with the UV positions; generating an external mesh and associated augmented reality (AR) element representing the real-world object based on the pixel values associated with the UV positions; deforming the external mesh based on changes to the 3D body mesh and a deformation parameter; and modifying the video to replace the real-world object with the AR element based on the deformed external mesh.

Abstract: An optical arrangement to transmit an image from an image plane to a user's eye. The arrangement providing a folded optical transmission path comprising a collimating element, having a first optical element with a first plurality of optically powered surfaces; and a second optical element comprising at least one optically powered surface. The collimating element to receive light forming the image from an image source and collimate and output the light. The optically powered surfaces having a plurality of interfaces along the folded optical path. A refractive index change at each interface is predetermined to control the direction of light passing through each interface. One surface of each of the first and the second optical elements being adjacent to one another. The adjacent surfaces having dissimilar shapes and each defining an angle with a respective other surface of the relevant optical element at opposing ends of the adjacent surfaces.

Abstract: A neural network pruning system can sparsely prune neural network models using an optimizer based approach that is agnostic to the model architecture being pruned. The neural network pruning system can prune by operating on the parameter vector of the full model and the gradient vector of the loss function with respect to the model parameters. The neural network pruning system can iteratively update parameters based on the gradients, while zeroing out as many parameters as possible based a preconfigured penalty.

Abstract: A compact generative neural network can be distilled from a teacher generative neural network using a training network. The compact network can be trained on the input data and output data of the teacher network. The training network train the student network using a discrimination layer and one or more types of losses, such as perception loss and adversarial loss.

Abstract: Systems and methods are provided. For example, a method includes determining a position of a user's hand and identifying a manipulation gesture performed by the user targeting a virtual object. The method also includes determining a three-dimensional (3D) origin point based on the position of the user's hand when the manipulation gesture is performed, and determining a 3D end point based on a movement of the user's hand from the origin point. The method additionally includes deriving a 3D vector based on the 3D origin point and the 3D end point, and applying an action to the targeted virtual object based on the 3D vector, wherein the targeted virtual object is at a distance greater than the user's arm reach.
