Publication number: 20240085328Abstract: Systems and methods are provided for excitation spectral microscopy using frame-synchronized acousto-optic scanning of fluorescent excitation wavelengths. Linear unmixing of the images of targets of components that are individually labeled with different fluorophores can be simultaneously imaged with high temporal resolution and low crosstalk and the local abundance of each fluorophore at each pixel can be quantified. Fluorophore decomposed micrographs of the sample can be obtained by rendering the abundance in each pixel as an image.Type: ApplicationFiled: October 11, 2023Publication date: March 14, 2024Applicant: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Ke Xu, Kun Chen, Rui Yan, Limin Xiang

Publication number: 20230169794Abstract: Methods, devices and computer-readable media for processing a compressed video to perform an inference task are disclosed. Processing the compressed video may include selecting a subset of frame encodings of the compressed video, or zero or more modalities (RGB, motion vectors, residuals) of a frame encoding, for further processing to perform the inference task. Pre-existing motion vector and/or residual information in frame encodings of the compressed video are leveraged to adaptively and efficiently perform the inference task. In some embodiments, the inference task is an action recognition task, such as a human action recognition task.Type: ApplicationFiled: November 30, 2021Publication date: June 1, 2023Inventors: Irina KEZELE, Mostafa SHAHABINEJAD, Seyed shahabeddin NABAVI, Wentao LIU, Yuanhao YU, Rui Xiang CHAI, Jin TANG, Yang WANG

Patent number: 7910256Abstract: The present invention provides a method for supplying fuel to a fuel cell, in which a monitoring period is determined for monitoring the fuel cell, and then a feeding amount of fuel is determined by integrating characteristic value generated from the fuel cell in the monitoring period. In another embodiment, it is further comprising a step of determining the variation profile associated with the characteristic value during the period so as to judge whether it is necessary to feed the fuel into the fuel cell or not. By means of the present invention, the supplying of fuel to the fuel cell under dynamic loadings can be effectively controlled for optimizing the performance of the fuel cell as well as reducing the cost without installing any fuel sensor.Type: GrantFiled: September 10, 2008Date of Patent: March 22, 2011Assignee: Institute of Nuclear Energy Research Atomic Energy Council, Executive YuanInventors: Charn-Ying Chen, Chun-Lung Chang, Der-Hsing Liou, Chih-Yuan Hsu, Rui-Xiang Wang
