  • Patent number: 11967744
    Abstract: A fuel cell vehicle includes a bypass valve positioned downstream of a compressor and upstream of a fuel cell stack to selectively direct airflow from the compressor to an exhaust bypassing the fuel cell in an attempt to clear a partially or fully obstructed exhaust pipe. The bypass valve may be opened by a controller when an exhaust throttle valve is at or near a wide-open throttle position. The controller may also increase compressor flow and adjust airflow to the fuel cell stack until compressor pressure, speed, or temperature exceed corresponding limits.

  • Patent number: 11957444
    Abstract: This specification describes systems and methods for using Zero Echo Time (ZTE) magnetic resonance imaging (MRI) sequences for applications to functional MRI (fMRI). In some examples, a system for functional magnetic resonance imaging includes a magnetic resonance imaging (MRI) scanner and a control console implemented on at least one processor. The control console is configured for executing, using the MRI scanner, a zero echo time (ZTE) pulse sequence; acquiring, using the MRI scanner, magnetic resonance data in response to the ZTE pulse sequence; and constructing at least one MRI image using the magnetic resonance data and measuring tissue oxygenation (PtO2)-related T1 changes as a proxy of neural activity changes of a subject using the at least one MRI image.

  • Publication number: 20240114138
    Abstract: In transform coefficient coding, predetermined sets of transforms may be used. Embodiments of the present invention provide an encoder and a decoder for encoding a picture into/from a data stream using block-based prediction and block-based residual coding, the encoder and decoder supporting a set of transforms for the block-based residual coding. The encoder and decoder are configured to determine a transform candidate list of transforms for a current residual block out of the set of transforms based on a height and a width of the current residual block, and to encode/decode a prediction residual within the residual block using one selected transform out of the selectable list of transforms and selectively signal/derive the selected transform in/from the data stream.
