  • Publication number: 20240177466
    Abstract: A method performed by an electronic apparatus, includes: determining a local frame sequence from a video; obtaining a feature map sequence of the local frame sequence by encoding the local frame sequence; determining a feature flow sequence of the local frame sequence based on the feature map sequence of the local frame sequence and a mask image sequence regarding an object to be removed, the mask image sequence being corresponding to the feature map sequence; obtaining an updated feature map sequence of the local frame sequence, by performing, based on the feature flow sequence, feature fusion between adjacent feature maps in the feature map sequence; and obtaining a processed local frame sequence, by decoding the updated feature map sequence of the local frame sequence.

  • Patent number: 9174645
    Abstract: The present disclosure provides systems and methods to detect and reduce any high driveline torsional levels, such as due to the cylinder deactivation in variable displacement system engines or aggressive lock-up strategies for fuel efficiency, in automobile transmissions. The present disclosure utilizes a controller in an automobile to operate a computationally thrifty method for quickly detecting noise and vibration disturbances in the transmission. This quick detection enables fuel economic calibrations that aggressively reduce the disturbances by controlling slip in a launch device of the transmission. As problem disturbances arise, they are detected before occupants notice objectionable behavior. Once detected, the disturbances are reduced, such as by increasing launch device slip, which effectively intercepts the objectionable disturbances before they are transferred through the entire drivetrain.

  • Patent number: 9151383
    Abstract: A method for interactive transmission garage shifts includes receiving a request for a transmission garage shift; controlling the transmission to bring the vehicle to a stop state based on determining that the vehicle is rolling backwards on a grade above a predetermined grade threshold and at a speed below a predetermined speed threshold; controlling an electric park brake (EPB) to hold the vehicle at the stop state; controlling the transmission to engage a dog clutch so as to place the transmission in a forward drive gear; and controlling the EPB to i) deactivate if the dog clutch is determined to be engaged, or ii) maintain activation to maintain the vehicle at the stop state if the dog clutch is determined to be disengaged.
