Patent number: 11893674Abstract: Aspects of the present disclosure are directed to creating interactive avatars that can be pinned as world-locked artificial reality content. Once pinned, an avatar can interact with the environment according to contextual queues and rules, without active control by the avatar owner. An interactive avatar system can configure the avatar with action rules, visual elements, and settings based on user selections. Once an avatar is configured and pinned to a location by an avatar owner, when other XR devices are at that location, a central system can provide the avatar (with its configurations) to the other XR device. This allows a user of that other XR device to discover and interact with the avatar according to the configurations established by the avatar owner.Type: GrantFiled: February 22, 2022Date of Patent: February 6, 2024Assignee: Meta Platforms Technologies, LLCInventors: Campbell Orme, Matthew Adam Hanson, Daphne Liang, Matthew Roberts, Fangwei Lee, Bryant Jun-Yao Tang

Patent number: 11880950Abstract: Implementations selectively offload visual frames from a client device to an edge system for processing. The client device can receive streaming visual frames and a request to process the visual frames using a data service. The client device can offload visual frames to an edge system preloaded with a workload resource that corresponds to the requested data service. After the edge system processes the offloaded visual frames using the workload resource, the edge system can return the processed visual frame to the client device. In some implementations, the edge system and client device are situated in a network such that a latency for the offload communications support real-time video display. A cloud system can maintain a registry of edge systems and provide client devices with information about nearby edge systems. The cloud system can also preload the edge systems with workload resources that correspond to data services.Type: GrantFiled: March 14, 2022Date of Patent: January 23, 2024Assignee: Meta Platforms Technologies, LLCInventors: Pranav Saxena, Brian Johnston, Jun Woo Shin, Tao Tao, Alaukik Aggarwal

Patent number: 11878493Abstract: A polymer bilayer includes a layer of a porous fluoropolymer directly overlying a layer of polyethylene. The polyethylene layer may be porous or dense and may include an ultra-high molecular weight polymer. The polymer bilayer may be co-integrated with structures (e.g., wearable devices) exposed to high thermal loads (>0-1000 W/m2) and provide passive cooling thereof. For instance, passive cooling of AR/VR glasses under different solar loads may be achieved by a polymer bilayer that is both highly reflective across solar heating wavelengths and highly emissive in the long-wavelength infrared. The high reflectance decreases energy absorption across the solar spectrum while the high emissivity promotes radiative heat transfer to the surroundings.Type: GrantFiled: June 17, 2022Date of Patent: January 23, 2024Assignee: Meta Platforms Technologies, LLCInventors: Arman Boromand, Sheng Ye, Andrew John Ouderkirk, Christopher Stipe
