Patent number: 11215712Abstract: A depth camera assembly is used to obtain depth information describing a local area. The depth camera assembly includes a sensor having a plurality of pixels. Some or all of the pixels are divided into groups that are coupled to respective multi-purpose time-to-digital converters. Each multi-purpose time-to-digital converter comprises an oscillator and a counter. Each pixel in a group is associated with a multiplexer that is configured to select between inputs coupled to the pixel, the oscillator, or a counter associated with a different pixel. The multiplexer outputs the signal to the counter for the time-to-digital converter associated with the pixel. A time-of-flight measurement is taken during a first portion of an image frame. During a second portion of the image frame, the sensor may be used as an intensity counter. During a third portion of the image frame, the depth sensor may be calibrated.Type: GrantFiled: April 27, 2020Date of Patent: January 4, 2022Assignee: Facebook Technologies, LLCInventors: Augusto Ronchini Ximenes, Michael Hall

Patent number: 11204100Abstract: A fluidic device comprises a channel, a gate, and one or more additional elements. The channel is configured to transport a fluid from a source to a drain. The gate includes a chamber with an adjustable volume that affects fluid flow within the channel by displacing a wall of the channel toward an opposite wall of the channel based in part on fluid pressure within the chamber exceeding a threshold pressure. A high pressure state of the gate corresponds to a first chamber size and a first flow rate of the fluid. A low pressure state of the gate corresponds to a second chamber size that is smaller than the first chamber size and a second flow rate that is greater than the first flow rate. The additional elements are configured to reduce the threshold pressure past which the chamber decreases the cross-sectional area of the channel.Type: GrantFiled: November 19, 2019Date of Patent: December 21, 2021Assignee: Facebook Technologies, LLCInventors: Sean Jason Keller, David R. Perek, Tristan Thomas Trutna, Garrett Andrew Ochs, Nicholas Roy Corson, Raymond King, Jack Lindsay, Riccardo DeSalvo, Joseph Minh Tien, Matthew Robert Schwab

Patent number: 11206443Abstract: This disclosure describes a video co-watching system that can efficiently, flexibly, and securely provide access to, and synchronize, co-watching digital video content across multiple participant devices while providing live digital video chat streams between the participant devices. For example, the video co-watching system can enable the participant devices to simultaneously present co-watching digital video content together with a presentation of a video chat. In addition, the video co-watching system can synchronize the co-watching digital video content at each participant device while also facilitating video chatting between the participant devices by transmitting a playback modifier signal to cause one participant device to perform a modification to the playback made at another participant device.Type: GrantFiled: August 6, 2020Date of Patent: December 21, 2021Assignee: FACEBOOK, INC.Inventors: Pablo Jose Barvo, Zheng Fang, Nora Micheva

Patent number: 11206235Abstract: Systems, methods, and non-transitory computer-readable media can determine that broadcasting of a live content stream has concluded. The concluded live content stream is converted to a post live media content item. The post live media content item corresponding to the concluded live content stream is published through the social networking system. The post live media content item remains accessible through the social networking system for a pre-determined period of time.Type: GrantFiled: April 26, 2018Date of Patent: December 21, 2021Assignee: Facebook, Inc.Inventors: Shilpa Sarkar, Mari Sheibley, Lu D. Chen, Vincent Yu-Shien Chen, Nayeon Kim, Ankur Sadhoo, Rohan Roy Choudhury, Aman Jain, Lukas Camra, Ang Li

Patent number: 11205069Abstract: A hybrid cornea and pupil eye-tracking technique includes receiving iris-backscattered light from an eye and determining a pupil-position of the eye based on the iris-backscattered light. Cornea-reflected light is received from the eye and an eye-tracking position of the eye is determined based on the cornea-reflected light and the pupil-position.Type: GrantFiled: February 20, 2020Date of Patent: December 21, 2021Assignee: Facebook Technologies, LLCInventors: Robin Sharma, Javier San Agustin Lopez, Karol Constantine Hatzilias, Sebastian Sztuk, Kun Liu, Jixu Chen

Patent number: 11199905Abstract: A haptic-jamming device may include (1) a first haptic-jamming member having a polarizable first element rotatable about an axis and a first elongated extension outwardly disposed from the first element in a first direction, (2) a second haptic-jamming member having a second element rotatable about the axis and a second elongated extension outwardly disposed from the second element in a second direction, and (3) a variable voltage source for at least one of the first haptic-jamming member or the second haptic-jamming member that, when energized, generates an electrostatic field encompassing at least one of the first or second elements. A level of separation of the first and second elements may be related to a strength of the electrostatic field. Various other methods, systems, and wearable articles are also disclosed.Type: GrantFiled: March 2, 2021Date of Patent: December 14, 2021Assignee: Facebook Technologies, LLCInventor: Ali Israr

Patent number: 11200284Abstract: A system trains models to generate embeddings that represent likelihoods associated with features. For example, an embedding may be generated for users and pages such that a user's embedding represents how likely a user is to comment on a given page. Initially, memory space for storing each embedding may be overprovisioned. The system monitors the embeddings for a feature as they are generated and recalculated over time. If the system detects that a particular index value is never updated for embeddings of that feature, then the system may remove that value from the feature embeddings. This allows the array lengths of embeddings to be customized to the particular features they represent, saving memory space. The system may further use related information to identify pooling functions that are most effective for particular features, to identify similarities between entities, and to provide insight into how the feature data influences neural network layers.Type: GrantFiled: April 30, 2018Date of Patent: December 14, 2021Assignee: Facebook, Inc.Inventors: Miao Li, Sagar Chordia, Harsh Doshi, Xianjie Chen, Qin Huang

Patent number: 11202091Abstract: The present invention relates to a method for encoding/decoding a quantization coefficient, and to an apparatus using same. The decoding method can include the steps of: decoding initial quantization parameter information and quantization parameter range information of a slice; and obtaining a quantization parameter limitation range applied to an encoding unit included in the slice using the initial quantization parameter information and the quantization parameter range information. Accordingly, the efficiency of encoding and decoding an image can be improved during encoding/decoding.Type: GrantFiled: December 18, 2018Date of Patent: December 14, 2021Assignee: Facebook, Inc.Inventor: Sun Young Lee

Patent number: 11198125Abstract: The disclosed microfluidic valves may include a valve body having at least one cavity therein, a gate transmission element separating the cavity into an input gate terminal and an output gate terminal, a gate port configured to convey drive fluid into the input gate terminal, and a fluid channel. The gate transmission element may include a flexible membrane and a plunger coupled to the flexible membrane. The gate transmission element may be configured to move within the cavity to inhibit a subject fluid flow from an inlet port to an outlet port of the fluid channel upon pressurization of the input gate terminal, and to allow subject fluid flow from the inlet port to the outlet port upon depressurization of the input gate terminal. Various other related systems and methods are also disclosed.Type: GrantFiled: February 19, 2019Date of Patent: December 14, 2021Assignee: Facebook Technologies, LLCInventors: Sean Jason Keller, Nicholas Roy Corson, Yigit Mengue
