Patent number: 12223591Abstract: Various techniques pertaining to methods, systems, and computer program products a spatial persistence process that places a virtual object relative to a physical object for an extended-reality display device based at least in part upon a persistent coordinate frame (PCF). A determination is made to decide whether a drift is detected for the virtual object relative to the physical object, upon or after detection of the drift or deviation, the drift or deviation is corrected at least by updating a tracking map into an updated tracking map and further at least by updating the persistent coordinate frame (PCF) based at least in part upon the updated tracking map, wherein the persistent coordinate frame (PCF) comprises six degrees of freedom relative to the map coordinate system.Type: GrantFiled: March 7, 2024Date of Patent: February 11, 2025Assignee: Magic Leap, Inc.Inventors: Yilun Cao, Mohan Babu Kandra, David Geoffrey Molyneaux, Daniel Olshansky, David Paul Pena, Frank Thomas Steinbrücker, Rafael Domingos Torres

Patent number: 11831001Abstract: Pre-lithiation methods using lithium vanadium fluorophosphate (e.g., LiVPO4F and its derivatives) (“LVPF”) as a cathode active material in a lithium-ion secondary battery. The pre-lithiation methods include compensating for an expected loss of active lithium by selecting LVPF having a specific pre-lithiated chemistry (or a blend of LVPF selected to have a specific pre-lithiated chemistry) and selecting a total amount of the pre-lithiated LVPF. The pre-lithiation methods may include initially charging the lithium-ion secondary battery at the lower of the two charge/discharge plateaus of LVPF to release active lithium.Type: GrantFiled: May 13, 2021Date of Patent: November 28, 2023Assignee: SAFT AMERICAInventors: Xilin Chen, Frank Cao, Tyler Ruff, Jian Dong, Carine Margez Steinway, Thomas Greszler, Kamen Nechev
