  • Automatic retargeting for matching avatars
    Patent number: 12770312
    Abstract: Transferring an animation from a source avatar to a target avatar includes identifying a first set of segments comprising a first skeleton from an animation for a source avatar, obtaining a second set of segments comprising an intermediate skeleton, determining positional information for each of the first set of segments, modifying the intermediate skeleton based on the positional information, and applying the intermediate skeleton to a target avatar. The positional information includes rotation information for each segment, which is transferred to corresponding segments of the intermediate skeleton to obtain a posed intermediate skeleton. The intermediate skeleton is fit to the target skeleton to translate the pose of the source avatar to the target avatar.

  • Method and device for tilt compensation in an optical storage system
    Patent number: 7633841
    Abstract: The invention relates to a tilt controller for controlling the tilt (radial and/or tangential) of an actuator relative to a recording surface of an optical storage medium, compensation for the radial to tilt crosstalk being effected by feeding a filtered version of the radial control signal (r) into the tilt branch, and/or compensation for the focus to tilt crosstalk being effected by feeding a filtered version of the focus control signal (f) into the tilt branch.
