  • Patent number: 12085887
    Abstract: A fixing device includes a first rotatable body, a second rotatable body, a frame, and a shutter. The frame supports the first rotatable body and the second rotatable body. The first rotatable body and the second rotatable body provide a nipping region therebetween where a sheet is configured to be conveyed in a conveying direction. The sheet is configured to pass through an opening of the frame to be conveyed toward the nipping region. The shutter is pivotally movable about a first axis between a closed position where the shutter closes the opening and an open position where the shutter opens the opening. The first axis is positioned downstream of the nipping region in the conveying direction.

  • Patent number: 11054802
    Abstract: A method for machining a workpiece by a numerical control (NC) machine constructs a model of a scene from one or multiple images including at least a part of the workpiece and a part of the NC machine and registers a model of the NC machine with the model of the scene to produce a first transformation between a coordinate system of the model of the scene and a coordinate system of the NC machine. The method also detects the workpiece in the model of the scene to produce a second transformation between the coordinate system of the model of the scene and a coordinate system of the workpiece and combines the first and the second transformations to register the coordinate system of the workpiece with the coordinate system of the NC machine. The registered workpiece is machined with a tool of the NC machine.

  • Patent number: 10909369
    Abstract: A method and system detects and localizes multiple instances of an object by first acquiring a frame of a three-dimensional (3D) scene with a sensor, and extracting features from the frame. The features are matched according to appearance similarity and triplets are formed among matching features. Based on 3D locations of the corresponding points in the matching triplets, a geometric transformation is computed. Matching triplets are clustered according to the computed geometric transformations. Since the set of features coining from two different object instances should have a single geometric transform, the output of clustering provides the features and poses of each object instance in the image.
