Patent number: 10831286Abstract: In one embodiment, a method includes receiving light signals from an interaction device, where the captured light signals are processed into one or more images that include illumination patterns associated with one or more objects, accessing light signals only within a particular spectrum range, detecting one or more tracking patterns from the accessed light signals within the particular spectrum range, where each of the one or more tracking patterns indicates a particular portion of a first object, and where the first object is a part of the one or more objects, determining one or more characteristics of the first object based on the detected one or more tracking patterns, and sending one or more content items and instructions causing a projector to project the one or more content items on the first object to the interaction device.Type: GrantFiled: January 9, 2019Date of Patent: November 10, 2020Assignee: Facebook, Inc.Inventors: Samuel Franklin Pepose, Walter Luh, Alexander Mortimer, Rajesh Prasannavenkatesan

Patent number: 10821772Abstract: In one embodiment, a method includes determining an ornamental pattern to be transferred to a substrate. The ornamental pattern is specific to a particular user, and one or more parameters of the ornamental pattern are based at least in part on social-graph information of the user. The method also includes generating one or more instructions for controlling a laser-treatment system to transfer the ornamental pattern to the substrate; sending the instructions to the laser-treatment system to transfer the ornamental pattern to the substrate; and transferring the ornamental pattern to the substrate.Type: GrantFiled: July 24, 2018Date of Patent: November 3, 2020Assignee: Facebook, Inc.Inventors: Rajesh Prasannavenkatesan, Richard Heley

Patent number: 10623695Abstract: A video messaging device includes a levitating unit and a base unit that each have one or more electromagnets and one or more magnets that are positioned such that when the device is in use and the electromagnet(s) are activated, the electromagnet(s) repel each other or the magnet(s), causing the levitating unit, which includes a camera, to levitate above the base unit. The levitating unit may include a top member and a bottom member, in which the top member, which includes the camera, is configured to rotate relative to the bottom member of the levitating unit to counteract rotation of the bottom member of the levitating unit about a vertical axis relative to the base unit. Alternatively, the levitating unit may include a camera configured to capture a 360-degree field of view and software may be used to eliminate the effect of rotation of the camera about the vertical axis.Type: GrantFiled: September 4, 2018Date of Patent: April 14, 2020Assignee: Facebook, Inc.Inventor: Rajesh Prasannavenkatesan

Publication number: 20190111597Abstract: An electronic device chassis is manufactured with a multi-step molding process. The process includes at least two separate injection molding steps. During the first step, an electronic component is placed in a first mold, and a first material is injected into the first mold to create a first chassis that surrounds part of the electronic component. In the second step, the first chassis is placed in a second mold, and a second material is injected into the second mold to create a second chassis that surrounds part of the first chassis. The second step can be performed at a higher pressure than the first step, which can produce a smoother exterior surface. Furthermore, the first chassis shields the electronic component from the higher pressure of the second step, which reduces the likelihood of damage to the electronic component.Type: ApplicationFiled: October 18, 2017Publication date: April 18, 2019Inventors: Rajesh Prasannavenkatesan, Rex Wenters Crossen, Richard Heley

Publication number: 20190062885Abstract: Embodiments relate to a type of aluminum alloy with grains visible to naked eyes. The aluminum alloy may have an average grain size of at least 100 ?m. The aluminum alloy can be produced by a process such as casting, extrusion, solutionizing, aging, and etching. The solutionizing causes recrystallization of aluminum and causes grains of the aluminum to grow. Compared with the solutionizing, the aging is performed at lower temperature but enhances strength of the aluminum alloy. The etching makes grain boundaries of the aluminum alloy more prominent, rendering the grains of the aluminum alloy visible to a naked human eye.Type: ApplicationFiled: February 13, 2018Publication date: February 28, 2019Inventors: Rajesh Prasannavenkatesan, Richard Heley, Michael Beadle

Patent number: 10166590Abstract: A method of forming a part includes: inserting a blank into a die, the die comprising a mold mounted above a sealing counterpart; clamping the blank between the mold and the sealing counterpart; applying first pressure on the blank from the sealing counterpart so the blank is pressed upward to form a shaped part corresponding to the mold; applying a vacuum to the shaped part to hold it against the mold also after separating the mold and the sealing counterpart, the vacuum applied through at least one opening in the mold located in a corner of the mold that the blank does not reach when the first pressure is applied; and discontinuing the vacuum to allow the shaped part to be released from the mold.Type: GrantFiled: September 25, 2015Date of Patent: January 1, 2019Assignee: Tesla, Inc.Inventors: Rajesh Prasannavenkatesan, Matthew Parker, Yvon Laplante, Nicolas Bombardier, Ben Rush, Shi Li
