Patent number: 9863554Abstract: A method of controlling subsea laying of an elongate article includes guiding the article using a submersible vehicle such as an ROV that carries a guide tool. The guide tool has a sleeve through which the article moves axially during laying, while the vehicle applies cross-axial guide forces to the article via the sleeve. Also disclosed is a guide tool including a sleeve through which the article can move axially during laying, and a grab handle whereby a submersible vehicle may hold the tool using a grabber. Alternatively, the guide tool can be attached to or integrated with the vehicle.Type: GrantFiled: February 8, 2016Date of Patent: January 9, 2018Assignee: Subsea 7 Norway ASInventors: Jan Henry Hansen, Eskil Hoyvik

Patent number: 8494815Abstract: A method for designing a sound waveguide surface is described. The method includes the steps of forming a parametric model of the sound waveguide surface where the parametric model has at least one input parameter and then simulating a sound field that is formed by the sound waveguide surface. A frequency dependent spatial distribution measure is then determined for the sound field associated with the sound waveguide surface and the at least one input parameter is varied to change the sound waveguide surface to adjust the value of the frequency dependent spatial distribution measure.Type: GrantFiled: February 28, 2011Date of Patent: July 23, 2013Assignee: Krix Loudspeakers Pty LtdInventors: Anthony Charles Zander, David John Murphy, Richard Christie Morgans, Colin Henry Hansen

Patent number: 6424745Abstract: A method and system for optically recognizing an object from a reference library of known products based on a spectrum of local radius of curvature of the object. A surface portion of an object is illuminated with a pattern of light that permits the extraction of three dimensional coordinates for a set of points on the surface portion of the object. An image data set of the surface portion of the object is then captured with a capture device that is positioned at an angular offset with respect to a source of the light. That is, the combination of the light pattern and the imaging device together generate a two dimensional captured image, from which it is possible to extract the three dimensional coordinates for the set of points on the surface portion of the object. A set of local radii of curvatures are then determined for selected data points in the image data set. A spectrum representing a distribution of the curvatures is then computed for the set of local radii of curvatures.Type: GrantFiled: May 19, 1998Date of Patent: July 23, 2002Assignee: Lucent Technologies Inc.Inventors: Mark Henry Hansen, Harald F.
