  • Publication number: 20220183590
    Abstract: A system and method for determining a sleep posture of a subject uses a three-axis accelerometer coupled to the subject. A plurality of three-axis acceleration signals of the three-axis accelerometer are analyzed over time and from this analysis a reference craniocaudal rotation axis is derived. For an acceleration measurement of interest (i.e. at a particular point in time) a rotation angle can then be determined about the reference craniocaudal rotation axis, thus indicating a sleep posture relative to that reference craniocaudal rotation axis.

  • Publication number: 20090263095
    Abstract: The invention relates to a method for integrating a light guide (1) in or onto a support structure (3), wherein said parts (1,3) are molded and wherein during this molding and/or a subsequent cooling down process, shrink behavior of the respective parts (1,3) is controlled in such way that both parts (1,3) shrink incompatibly, at least temporarily and at least near their bordering areas, thereby causing the parts (1,3) to be separated and an air gap (10) to be formed between their respective separation surfaces. Separation of the parts (1,3) can be promoted by making the parts of materials having incompatible melting points and/or incompatible chemical bonding properties. Incompatible shrinkage can be stimulated by appropriate parts design, by applying materials having incompatible shrink behavior and/or by exposing the parts to different molding and cooling down conditions. The invention furthermore relates to a support structure with light guide and a device comprising such a support structure.

  • Publication number: 20040165776
    Abstract: This application concerns an enhancement of the render, match, and refine (RMR) method [0002] for 3D scene model refinement. A method is provided that allows for the directed refinement of camera and geometry associated parameters of the 3D scene model in a manner that is independent of lighting, color, and texture. The method is based on the matching of a rendered motion vector field to a motion vector field estimated from a recorded video stream.

  • Publication number: 20040136590
    Abstract: The present invention is an enhancement of the render, match, and refine (RMR) method [0002] for scene model refinement. It provides a means of automatically subdividing the RMR problem such that the matching can operate on subsets of the 2D view plane, and refinement can operate on subsets of the scene model parameters with little interference between parameter subsets. Since run times of high-dimensional searches tend to scale exponentially with the number of dependent parameters and linearly with the number of independent parameters, this can vastly reduce the number RMR iterations required to achieve convergence.
