Publication number: 20240104872Abstract: Various implementations provide a view of a 3D environment including a portal for viewing a stereo item (e.g., a photo or video) positioned a distance behind the portal. One or more visual effects are provided based on texture of one or more portions of the stereo item, e.g., texture at cutoff or visible edges of the stereo item. The effects change the appearance of the stereo item or the portal itself, e.g., improving visual comfort issues by minimizing window violations or otherwise enhancing the viewing experience. Various implementations provide a view of a 3D environment including an immersive view of a stereo item without using portal. Such a visual effect may be provided to partially obscure the surrounding 3D environment.Type: ApplicationFiled: September 21, 2023Publication date: March 28, 2024Inventors: Bryce L.

Patent number: 11941818Abstract: Various implementations disclosed herein include devices, systems, and methods that determine a 3D location of an edge based on image and depth data. This involves determining a 2D location of a line segment corresponding to an edge of an object based on a light-intensity image, determining a 3D location of a plane based on depth values (e.g., based on sampling depth near the edge/on both sides of the edge and fitting a plane to the sampled points), and determining a 3D location of the line segment based on the plane (e.g., by projecting the line segment onto the plane). The devices, systems, and methods may involve classifying an edge as a particular edge type (e.g., fold, cliff, plane) and detecting the edge based on such classification.Type: GrantFiled: March 3, 2021Date of Patent: March 26, 2024Assignee: Apple Inc.Inventors: Vedant Saran, Alexandre Da Veiga

Publication number: 20240086394Abstract: The disclosure deals with a system and method for improved representation and retrieval of recipes or workflows. Recipes or workflows such as for preparing food or assembling furniture or performing other complex activities exist as textual or image documents, which makes it difficult for machines to read, reason, and handle ambiguity. The present disclosure provides a Rich Recipe Representation (“R3”), which is enhanced with additional knowledge such as outcomes like allergen information, possible failures, and solutions for each atomic step (such as a cooking step). The disclosed R3 is used in a web-based decision support system that helps users perform constrained queries using multiple modalities while also monitoring execution of an agent cooking or otherwise acting based on it.Type: ApplicationFiled: August 25, 2023Publication date: March 14, 2024Inventors: BIPLAV SRIVASTAVA, VISHAL PALLAGANI, REVATHY CHANDRASEKARAN VENKA, VEDANT KHANDELWAL, KAUSIK LAKKARAJU

Patent number: 11901888Abstract: A gate charge profiler for a power transistor may include a voltage comparator unit and a timer unit. An input signal may control a gate drive current input to a gate of the power transistor to control conduction between a drain and a source of the power transistor. The voltage comparator unit may be configured to compare an input voltage and a threshold voltage, and to output a comparison signal. The input voltage may be a drain-source voltage across the drain and the source of the power transistor or a gate-source voltage across the gate and the source of the power transistor. The timer unit may be configured to output a time value based on input of a transition of the input signal and input of the comparison signal.Type: GrantFiled: July 25, 2022Date of Patent: February 13, 2024Assignee: Infineon Technologies Austria AGInventors: Vedant Sadashiv Chendake, Giuseppe Bernacchia, Pablo Yelamos Ruiz

Publication number: 20240036324Abstract: A head-mounted device may include a main housing portion and a temple housing portion. Displays in the main housing portion may be configured to present images that are viewable from eye boxes. A light-blocking cover may extend between the main housing portion and the temple housing portion and may be configured to prevent outside light from reaching the eye boxes. The light-blocking cover may have a stretchable outer fabric layer and an inner light-blocking layer formed from fabric or other suitable materials. The light-blocking cover may include slack in the inner light-blocking layer so that the inner light-blocking layer can accommodate movement of the main housing portion relative to the temple housing portion without sacrificing opacity. The slack may be heat-set, molded, or covered with a layer of elastic so that the slack returns to a retracted state within the temple housing portion after being expanded.Type: ApplicationFiled: June 22, 2023Publication date: February 1, 2024Inventors: Darshan R.

Publication number: 20230350691Abstract: An indication that a virtual machine is starting is received. Requested data blocks associated with the virtual machine are identified. Based on identifiers of the requested data blocks, a trained learning model is used to predict one or more subsequent data blocks likely to be requested while the virtual machine is starting. The one or more subsequent data blocks are caused to be preloaded in a cache storage. It is determined that the one or more predicted subsequent data blocks are incorrect. It is determined that an end of a boot sequence associated with the virtual machine has been reached. In response to a determination that the end of the boot sequence associated with the virtual machine has been reached, the boot sequence associated with the virtual machine is used to update the trained learning model.Type: ApplicationFiled: July 10, 2023Publication date: November 2, 2023Inventors: Ayushi Jain, Vedant
