Publication number: 20240152257Abstract: A computer-implemented method is disclosed. The method includes causing display, in a graphical user interface on a client device, of a page with a navigational panel including a selectable tree element having a hierarchical relationship to a current electronic page having its user-generated content being displayed in a content panel. The method includes identifying a set of candidate cards in which each card is associated with a respective electronic page and has a respective relatedness score. The method includes identifying a user profile in accordance with an authentication of an user operating the client device, and selecting, from the set of candidate cards, a subset of candidate cards satisfying permissions criteria based on permissions identified in the user profile. The method includes causing display of the subset of candidate cards within the content panel in accordance with the respective relatedness score for each card in the subset of candidate cards.Type: ApplicationFiled: January 12, 2024Publication date: May 9, 2024Inventors: Henry Jetmundsen, Balazs Nagy, Jerry Qing, Swati Katta, Rudra Saha, Shawn Cao, Andrew Nelson, Arnav Garg, Frank Wang

Patent number: 11967021Abstract: 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: May 16, 2023Date of Patent: April 23, 2024Assignee: 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: 11955624Abstract: The present disclosure relates to blended cathode materials for use as a positive electrode material of a rechargeable electrochemical cell (or secondary cell) (such as a lithium-ion secondary battery) and also relates to a secondary battery including a cathode having the blended cathode materials. In particular, disclosed are blends of lithium vanadium fluorophosphate (LVPF) or a derivative thereof with one or more conventional cathode active materials in certain weight ratios thereof.Type: GrantFiled: October 29, 2020Date of Patent: April 9, 2024Assignee: SAFT AMERICAInventors: Xilin Chen, Frank Cao

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

Patent number: 11804601Abstract: Provided is a positive electrode active material for a lithium-ion battery, the positive electrode active material including a blend of a doped lithium manganese iron phosphate (dLMFP) according to the formula: LiMnxFeyM1?x?yPO4, wherein 0.9<x+y<1; and M is one or more selected from the group consisting of Mg, Ca and Ba with one or both of a lithium nickel cobalt manganese oxide (NMC) compound having a Ni content greater than 0.6 relative to a total amount of metals other than Li and a lithium nickel cobalt aluminum oxide (NCA) compound. In particular, provided is a blend at a weight ratio of dLMFP to NMC and/or NCA (i.e., dLMFP:(NMC+NCA)) of >70:<30, such as 75:25, 80:20, 85:15, 90:10, etc.Type: GrantFiled: September 12, 2019Date of Patent: October 31, 2023Assignee: SAFT AMERICAInventors: Xilin Chen, Saori Tokuoka, Frank Cao, Jian Dong, Carine Margez, Owen Ou, Thomas Greszler
