The optics block includes optical elements configured to direct the image light to an eyebox, and the optics block adds a second non-uniform brightness distribution that is offset by the first non-uniform brightness distribution, such that the image light directed to the eyebox has a target brightness distribution.Type: GrantFiled: December 21, 2018Date of Patent: October 20, 2020Assignee: Facebook Technologies, LLCInventors: Dong Chen, Shizhe Shen

Patent number: 10811575Abstract: Techniques related to laser lift-off masks are disclosed. In some embodiments, masking material is applied to a substrate that is attached to a plurality of semiconductor device sets. More specifically, the masking material is applied to one or more regions of the substrate between the semiconductor device sets. When the semiconductor device sets are embedded in a filling material, the masking material may be situated between the substrate and the filling material. Thus, transmitting light through the substrate toward the semiconductor device sets causes the substrate to become detached from the semiconductor device sets. However, the light is at least partially occluded by the masking material.Type: GrantFiled: July 30, 2018Date of Patent: October 20, 2020Assignee: FACEBOOK TECHNOLOGIES, LLCInventors: Daniel Brodoceanu, David Massoubre, James Small, Oscar Torrents Abad, Patrick Joseph Hughes

Patent number: 10809524Abstract: The disclosed apparatus may include (1) a deformable stepped lens that (a) provides a first optical power when a shape of the deformable stepped lens includes a first state, and (b) provides a second optical power different from the first optical power when the shape of the deformable stepped lens includes a second state different from the first state and (2) an actuator coupled to the deformable stepped lens that, when actuated, applies force to the deformable stepped lens to alter the shape of the deformable stepped lens from the first state to the second state. Various other apparatuses, systems, and methods are also disclosed.Type: GrantFiled: March 19, 2018Date of Patent: October 20, 2020Assignee: Facebook Technologies, LLCInventors: Alexander Sohn, Nelson Cardenas

Patent number: 10810277Abstract: Systems, methods, and non-transitory computer-readable media can determine a multi-part identifier captured using one or more cameras associated with the computing device, the multi-part identifier including at least a first portion that references a site, a second portion that references an entity, and information describing one or more actions. A digital destination associated with the multi-part identifier can be determined based at least in part on the first portion and the second portion of the multi-part identifier. One or more actions to be performed in relation to the digital destination can be determined based at least in part on the information included with the multi-part identifier.Type: GrantFiled: December 27, 2018Date of Patent: October 20, 2020Assignee: Facebook, Inc.Inventors: Maria Ioveva, Jake Bograd-Denton, Laycee Berkas

Patent number: 10810655Abstract: In one embodiment, a method includes receiving one or more order parameters from a client system of a first user of an online social network. The order parameters may include an identifier associated with the first user and a location of the client system. The method also includes receiving references to catalog items from third-party vendors. Each reference may be associated with one or more metadata items. The method also includes scoring each reference based at least in part on the one or more order parameters and the one or more metadata items. The method also includes sending to the client system of the first user one or more references of that has a score above a threshold score.Type: GrantFiled: January 4, 2018Date of Patent: October 20, 2020Assignee: Facebook, Inc.Inventors: Gery Gutnik, Mark J. Kilgore, Ken Deeter

Patent number: 10809448Abstract: A nano-structure includes an outer area at an edge of the nano-structure. A width of the outer area defined by a distance from the edge of the nano-structure is less than 100 ?m. A depth of the nano-structure in the outer area changes gradually between 0% and at least 50% of a maximum depth of the nano-structure. A method includes forming an etch mask on a substrate and etching the substrate with the etch mask using an ion beam to form a nano-structure in the substrate. The etch mask includes an outer area near an edge of the etch mask. A width of the outer area defined by a distance from the edge of the etch mask is less than 100 ?m. A duty cycle of the etch mask in the outer area changes gradually between at least 10% and at least 90%.Type: GrantFiled: April 18, 2019Date of Patent: October 20, 2020Assignee: FACEBOOK TECHNOLOGIES, LLCInventor: Giuseppe Calafiore
