Publication number: 20240104338Abstract: A method comprising: sampling a temporal causal graph from a temporal graph distribution specifying probabilities of directed causal edges between different variables of a feature vector at a present time step, and from one variable at a preceding time step to another variables at the present time step. Based on this there are identified: a present parent which is a cause of the selected variable in the present time step, and a preceding parent which is a cause of the selected variable from the preceding time step. The method then comprises: inputting a value of each identified present and preceding parent into a respective encoder, resulting in a respective embedding of each of the present and preceding parents; combining the embeddings of the present and preceding parents, resulting in a combined embedding; inputting the combined embedding into a decoder, resulting in a reconstructed value of the selected variable.Type: ApplicationFiled: September 28, 2022Publication date: March 28, 2024Inventors: Wenbo GONG, Cheng ZHANG, Nick PAWLOWSKI, Joel JENNINGS, Karen FASSIO, Marife DEFANTE, Steve THOMAS, Alice HORAN, Chao MA, Matthew ASHMAN, Agrin HILMKIL

Patent number: 11936733Abstract: A host device having a first processor executes an application via the first processor. The host device determines a state of the application. A scenegraph is generated corresponding to the state of the application, and the scenegraph is presented to a remote device having a display and a second processor. The remote device is configured to, in response to receiving the scenegraph, render to the display a view corresponding to the scenegraph, without executing the application via the second processor.Type: GrantFiled: November 8, 2021Date of Patent: March 19, 2024Assignee: Magic Leap, Inc.Inventors: Praveen Babu J D, Karen Stolzenberg, Jehangir Tajik, Rohit Anil Talwalkar, Colman Thomas Bryant, Leonid Zolotarev

Publication number: 20230290936Abstract: Systems, methods, and devices of various aspects include using tin, antimony, and/or indium as an additive to an electrolyte and/or electrode in an electrochemical system, such as a battery, having an iron-based anode. In some aspects, the addition of tin, antimony, and/or indium may improve cycling of the iron-based anode. Systems, methods, and devices of various aspects include using high hydroxide concentration electrolyte in an electrochemical system, such as a battery. In some aspects, a high hydroxide concentration electrolyte may increase the stored amount of charge stored in the cell (i.e., the capacity of the battery material) and/or decrease the overpotential (i.e., increase the voltage) of the battery.Type: ApplicationFiled: October 27, 2022Publication date: September 14, 2023Inventors: Annelise Christine THOMPSON, Michael Andrew GIBSON, William Henry WOODFORD, Rebecca Marie EISENACH, Jocelyn Marie NEWHOUSE, Nicholas Reed PERKINS, Olivia Claire TAYLOR, Kjell William SCHRODER, Karen THOMAS-ALYEA, Zachariah NORMAN, Johanna GOODMAN, Jonathan Thomas VARDNER, Benjamin Thomas HULTMAN, Sydney GARY, Natalie MAKO, Renee MITCHELL, Brooke WOJESKI, Jarrod David MILSHTEIN

Patent number: 6325968Abstract: An outer, first container portion (50) has a peripheral wall (52) which has an opening at a first end (56) and at a second end (60). A porous filter (58) covers the second end. An inner, second container portion (70) has a peripheral wall (72) with a region which is formed from a first material which is impermeable to the powdered reagents but is permeable to water and to solutions containing dissolved reagents. The first and second container portions are configured such that the second container portion peripheral wall abuts and is connected to the first end of the outer first container portion. The first and second container portions define a first powdered reagent receiving chamber in the first container portion for receiving a first reagent and a second powdered reagent receiving chamber in the second container portion for receiving a second reagent.
