  • Publication number: 20250039330
    Abstract: A video data processing method includes receiving compressed video data that has first resolution, obtaining first texture data having the first resolution based on one or more first video frames in the compressed video data, generating second texture data having second resolution higher than the first resolution based on the first texture data, and generating one or more second video frames having the second resolution through a rendering operation and based on the second texture data.

  • Publication number: 20240392719
    Abstract: An exhaust aftertreatment system for a vehicle includes first and second longitudinal frame rails and may include a first housing including a first inlet configured to be fluidly coupled to a supply of a gas, a plurality of diesel oxidation catalysts fluidly coupled to the first inlet, a plurality of diesel particulate filters fluidly coupled to the plurality of diesel oxidation catalysts, and a mixing chamber fluidly coupled to the plurality of diesel particulate filters. The exhaust aftertreatment system may include second housing including an inner channel fluidly coupled to the mixing chamber of the first housing, a selective catalytic reduction catalyst fluidly coupled to the inner channel, and an outlet fluidly coupled to the selective catalytic reduction catalyst and configured to permit the gas to exit the system, wherein the first housing is fluidly coupled to the second housing by a connecting portion.

  • Patent number: 9574641
    Abstract: A large-torque chain-guide type constant ratio/continuously variable transmission is disclosed. The transmission comprises transmission rollers (A, B), an endless transmission chain or belt (C) and two chain guiders (D, E) respectively arranged beside the two transmission rollers. Each chain guider comprises n groups of grooved-pulleys, and each group comprises m grooved-pulleys. Each grooved-pulley rotates freely around a grooved-pulley axis, and an angle ? is formed between the axis of at least one grooved-pulley in each group of grooved-pulleys and a roller axis of the transmission roller matched with the same grooved-pulley. The angle ? enables the chain entering the chain guider and the chain leaving the chain guider to move a certain axial distance, i.e. a chain distance, on the transmission rollers, wherein the chain distance is required to be larger than the width of the chain or the belt.
