  • Publication number: 20250118963
    Abstract: The present disclosure provides a control method for suppressing an overvoltage of the receiving-end F/HMMC under the fault at the receiving-end alternating-current (AC) system of the hybrid high-voltage direct-current (HVDC) transmission system. After a short-circuit fault occurs in a receiving-end alternating-current (AC) system of the hybrid HVDC transmission system, an AC voltage drop is generated, and the effective voltage of the receiving-end AC bus at the current time is measured. Because the hybrid modular multilevel converter (MMC) has a capability of actively decreasing the DC voltage for operation, on a premise of ensuring that its output current is always within a rated current range, a control manner of setting the reference DC voltage and making the reference DC voltage not greater than the effective voltage of the AC bus enables receiving-end power to be sent out, thereby suppressing an overvoltage of the receiving-end F/HMMC.

  • Publication number: 20250111424
    Abstract: An online system hosts a retailer storefront user interface for a third-party retailer that includes content associated with items offered by the retailer for procurement and delivery through the online system. A retailer may provide preferences for where different candidate content is placed in the retailer storefront user interface. The online system applies a machine learning model to the retailer preferences and other contextual information relating to a particular presentation of the retailer storefront user interface to dynamically rank content for different possible placement positions. The ranking scores may relate to predicted performance metrics associated with operations of the online system. Content is then placed in the retailer storefront user interface based on the respective ranking scores.

  • Patent number: 12260338
    Abstract: A transformer-based neural network includes at least one mask attention network (MAN). The MAN computes an original attention data structure that expresses influence between pairs of data items in a sequence of data items. The MAN then modifies the original data structure by mask values in a mask data structure, to produce a modified attention data structure. Compared to the original attention data structure, the modified attention data structure better accounts for the influence of neighboring data items in the sequence of data items, given a particular data item under consideration. The mask data structure used by the MAN can have static and/or machine-trained mask values. In one implementation, the transformer-based neural network includes at least one MAN in combination with at least one other attention network that does not use a mask data structure, and at least one feed-forward neural network.

  • Patent number: 12249017
    Abstract: Devices and methods for reducing a DPU transfer time to compensate for a delayed GPU render time. After completion of rendering a second frame that follows a first frame, a frame processor determines whether the first frame is currently transferring to a display panel or has already been transferred to the display panel. At least one clock is used with a first set of clock speeds when the first frame is determined to be currently transferring and used with a second set of clock speeds when the first frame is determined to have already been transferred, the second set of clock speeds being faster than the first set of clock speeds. After completion of the transfer of the first frame, the second frame is transferred based on the set of clock speeds.

  • Patent number: 12249298
    Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for reducing gamut mapping luminance loss. A gain value of at least one primary color may be reduced in a native color gamut based on an analog technique (e.g., using a DDIC in a display panel) to provide a reduced color gamut that is smaller than the native color gamut. The reduced color gamut may have a same luminance as the native color gamut. One or more colors included in the native color gamut may be mapped via a digital technique (e.g., using a DPU or other processor) to the reduced color gamut. The mapping may be configured to provide a threshold level of color accuracy in the reduced color gamut.
