  • Patent number: 11941840
    Abstract: Apparatuses and methods determine the three-dimensional position and orientation of a fiducial marker and tracking the three-dimensional position and orientation across different fields-of-view. Methods include: capturing an image of a first space in which the fiducial marker is disposed with a first sensor having a first field-of-view; determining the three-dimensional location and orientation of the fiducial marker within the first space based on the image of the first space in which the fiducial marker is disposed; capturing an image of a second space in which the fiducial marker is disposed with a second sensor having a second field-of-view; calculating pan and tilt information for the second sensor to move the second field-of-view of the second sensor to acquire an image of the fiducial marker; and determining the three-dimensional location and orientation of the fiducial marker within the second space based on the image of the second space.

  • Patent number: 10732284
    Abstract: A method for live metrology of an object includes performing a scanning operation by a plurality of sensors to collect electronic images of an object. The electronic images include 3-D point cloud data for live metrology of the object and the point cloud data from each sensor define a point cloud that represents the object. The method also includes stitching the point clouds from the plurality of sensors to generate a reconstructed model of an as-manufactured object. The method further includes comparing the reconstructed model of the as-manufactured object to an as-designed model of the object to determine that the object is manufactured within an allowable tolerance to the as-designed model of the object.

  • Patent number: 6691700
    Abstract: A gas grill burner apparatus is provided that fits within barbecue grill cooking chambers of varied configurations and sizes. In accordance with one embodiment of the present invention, a gas grill burner apparatus includes a center manifold configured to form two hollow gas tubes, the gas tubes being substantially parallel. The gas grill burner apparatus also includes first and second C-shaped hollow gas tube end portions slideably engaged within opposing ends of the parallel hollow gas tubes. The apparatus further includes a center grease tent mounted atop the center manifold and first and second telescoping grease tent members mated with the center grease tent. The telescoping grease tent members are configured to move laterally with the first and second gas tube end portions.

  • Patent number: 6418923
    Abstract: A hood mounting device including at least one cam having a first surface and an aperture located on the bottom casting. At least one second surface is located on the grill hood and is configured such that the first and said second surfaces contact each other when the hood is placed in the closed position on the lower casting. The hood mounting device is configured such that a corresponding aperture formed in the hood is axially aligned with the aperture in the lower casting when the hood is in the closed position. Longitudinal securing means are passed through the axially aligned aperture and corresponding aperture, thereby rotatably securing the hood to the bottom casting.
