  • Publication number: 20250151236
    Abstract: Heat sink devices which gradually increase the effective heat transfer coefficient (HTC) of a cooling fluid flowing along a row of power electronics devices are described. The heat sink devices may allow substantially uniform cooling of the plurality of power electronics devices, regardless of the temperature of the cooling fluid when it contacts them. The heat sink devices allow the HTC to be increased as needed down the row of power electronics devices resulting in power electronics devices cooled to substantially the same temperatures. The heat sink devices may include fins.

    Abstract: Apparatuses, systems, and techniques for performing color correction are presented. In at least one embodiment, a color mapping model may be identified that maps colors, within a subspace of an input color space localized around a target color, to an adjusted color space and applied to an input image to adjust a value of one or more pixels of the input image that fall within the subspace. In at least one embodiment, a color mapping model may be initialized that maps colors, within a subspace of an input color space localized around a target color, to an adjusted color space. At least one parameter of the color mapping model may be adjusted to reduce an amount of visible artifacts produced by the color mapping model.
