  • Publication number: 20250191522
    Abstract: A display driving device includes a panel. The panel includes an output region, a first region, a second region, and a third region. The output region is configured to output a detection signal. The first region overlaps the output region, the second region overlaps the output region, and the third region overlaps the output region. During a first period, the second region and the third region output a point report signal according to the detection signal. During a second period, the first region and the third region output the point report signal according to the detection signal. During a third period, the first region and the second region output the point report signal according to the detection signal. The second period is later than the first period and the third period is later than the second period.

  • Patent number: 12135695
    Abstract: In an approach, a processor obtains a configuration file of a distributed file system federation, the configuration file comprising a list of a plurality of subclusters within the distributed file system federation and migration trigger factors for the plurality of subclusters. A processor determines a list of one or more source subclusters and a list of to-be-migrated directories in the one or more source subclusters based on a scanning result of the plurality of subclusters and the migration trigger factors in the configuration file. A processor generates a migration plan to migrate the to-be-migrated directories from the one or more source subclusters to one or more target subclusters in the distributed file system federation.

  • Patent number: 11675978
    Abstract: An approach is provided for improving a named entity recognition. Using a multi-label classification in a neural network, a sub-entity is identified in an original sentence. First and second labels are determined indicating first and second candidate types of the sub-entity. First and second replacement sentences are generated. The first replacement sentence replaces the sub-entity in the original sentence with a first sub-entity of the first candidate type. The second replacement sentence replaces the sub-entity in the original sentence with a second sub-entity of the second candidate type. First and second confidence scores for the first and second replacement sentences are determined. Based on the first confidence score exceeding the second confidence score by more than a threshold amount, the neural network is retrained by selecting the first instead of the second candidate type as the sub-entity type.

  • Publication number: 20220172106
    Abstract: One or more computer processors extract respective features for each inter-modal sample in an inter-modal dataset, for each intra-modal sample in an intra-modal dataset, and a subsequent sample, wherein the inter-modal dataset and the intra-modal dataset are contained in a multi-modal training dataset. The one or more computer processors estimate an inter-modal label utilizing inter-modal label transformation of a subsequent sample. The one or more computer processors estimate an intra-modal label utilizing intra-modal label transformation of the subsequent sample. The one or more computer processors label the subsequent sample with a cross-modal label by combining the estimated inter-modal label and the estimated intra-modal label.

  • Patent number: 8522058
    Abstract: A computer system with power source control and a power source control method are presented. The computer system at least includes a first storage unit and a second storage unit, and the first storage unit stores a system program required by the computer system in basic operation. A switch is disposed on a power supply path between a power supply module and the second storage unit, such that the power supply module provides an electric power for the second storage unit to operate through the switch. When the second storage unit is in an idle state, the switch is used to cut off the power supply to the second storage unit, so as to effectively reduce the power consumption of the computer system.
