Patent number: 10785471Abstract: A system for content upsampling comprises a console and a head-mounted display (HMD). The console can select content for presentation and provide the content at a first frame rate. The HMD outputs fast calibration data comprising one or more intermediate estimated positions of a reference point on the HMD. The HMD estimates future positions of the HMD using the fast calibration data, and generates synthetic frames using frames from the content and the future positions of the HMD. The HMD then upsamples the content from the first frame rate to a second frame using the synthetic frames to generate augmented content, wherein the second frame rate is faster than the first frame rate. The HMD presents the augmented content at the second frame rate via an electronic display.Type: GrantFiled: February 27, 2018Date of Patent: September 22, 2020Assignee: Facebook Technologies, LLCInventors: Warren Andrew Hunt, Devin Boyer, Nathan Bialke, William Howe-Lott, Hung Huu Nguyen

Patent number: 10755295Abstract: A method for determining an amount of electricity to purchase includes determining electrical power consumption characteristics of an electrical load at an end user of the electricity. A preference of the end user for an output of the electrical load is ascertained. The output varies with a rate of electrical power consumption by the load. A mathematical model is created of an amount of electrical power to be consumed by the load as a function of time and of monetary cost of the electricity. The model is dependent upon the electrical power consumption characteristics of the electrical load and the preference of the end user for an output of the electrical load. An amount of electricity is purchased based on the mathematical model of an amount of electrical power to be consumed by the load, and based on the monetary cost of the electricity.Type: GrantFiled: October 8, 2015Date of Patent: August 25, 2020Assignee: Robert Bosch GmbHInventors: Marija Dragoljub Ilic, Jhi Young Joo, Burton Warren Andrews, Badri Raghunathan, Diego Benitez, Felix Maus

Patent number: 10699467Abstract: In one embodiment, a method for determine visibility may perform intersection tests using block beams, tile beams, and rays. First, a computing system may project a block beam to test for intersection with a first bounding volume (BV) in a bounding volume hierarchy. If the beam fully contains BV, the system may test for more granular intersections with the first BV by projecting smaller tile beams contained within the block beam. Upon determining that the first BV partially intersects a tile beam, the system may project the tile beam against a second BV contained within the first BV. If the tile beam fully contains the second BV, the system may test for intersection using rays contained within the tile beam. The system may project procedurally-generated rays to test whether they intersect with objects contained within the second BV. Information associated with intersections may be used to render a computer-generated scene.Type: GrantFiled: April 16, 2018Date of Patent: June 30, 2020Assignee: Facebook Technologies, LLCInventors: Warren Andrew Hunt, Anton S.
