Publication number: 20240129759Abstract: Methods, systems, and devices for wireless communications are described. In some systems, devices use machine learning (ML) models to support wireless communications. For example, a user equipment (UE) may download ML model information from a network to determine an ML model. The network may additionally configure a status reporting procedure, a fallback procedure, or both for the ML model. In some examples, based on a configuration, the UE may transmit a status report to a base station according to a reporting periodicity, a UE-based trigger, a network-based trigger, or some combination thereof. Additionally or alternatively, the UE may determine to fallback from operating using the ML model to operating in a second mode based on a fallback trigger. In some examples, to restore operating using a downloaded ML model, the UE may download an updated ML model or receive iterative updates to a previously downloaded ML model.Type: ApplicationFiled: April 22, 2021Publication date: April 18, 2024Inventors: Yuwei Ren, Ruiming Zheng, Xipeng Zhu, Chenxi Hao, Shankar Krishnan, Yu Zhang, Huilin Xu, Hao Xu, Yin Huang, Taesang Yoo

Publication number: 20110123902Abstract: There is disclosed a direct fuel cell comprising an anode and a cathode immersed in an electrolyte in the presence of a reductant and oxidant. Specifically, the fuel cell lacks a permselective membrane or other chemical barrier between the anode and cathode. Instead, the fuel cell has a mechanical/electrical porous separator that permits the free diffusion of liquid between all elements of the fuel cell. The fuel cell further contains an anode electrode of conductive substrate with catalyst and a cathode comprising a hydrophobic coated material that prevents cathode flooding. As a result, oxidation of the anode fuel and reduction of the cathode fuel occur to a substantial extent only at the anode and cathode, respectively, and is capable for ambient pressure/temperature and passive operation.Type: ApplicationFiled: February 25, 2009Publication date: May 26, 2011Inventors: Ruiming Zhang, John Pope, Yinghui Pan
