  • Publication number: 20240085328
    Abstract: 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.

  • Patent number: 11729395
    Abstract: Devices and methods for extracting motion vector data during decoding compressed of video data are described. At a video decoder, an encoded video data for a frame of video from an input buffer is obtained. The encoded video data is decoded to obtain decoded image data for a decoded frame, where the decoding includes extracting corresponding motion vector data for the decoded frame. The decoded image data is stored in a temporary storage indexed with a given index, and the corresponding motion vector data is stored in a same or different temporary storage indexed with the given index. An output buffer indexed with the given index is filled with the decoded image data and the corresponding motion vector data stored in the respective temporary storage indexed with the given index.

  • Publication number: 20230169794
    Abstract: 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.

  • Patent number: 9417962
    Abstract: Technologies are described herein for recovering data in a storage device comprising a controller and a plurality of storage units. The controller receives a data stream, and divides the data stream into a plurality of data blocks, obtains a code block using the plurality of data blocks. When there is one or more blocks with damaged data in the plurality of data blocks and the code block, the controller obtains a sub-block from the Mth bit to the Nth bit of each block in the plurality of data blocks and the code block as a set, and reconstructs data in one or more sub-blocks with damaged data using other sub-blocks with undamaged data in the set.

  • Patent number: 7910256
    Abstract: 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.
