Patent number: 11938045Abstract: Breathable residual-limb system that admits air and allows sweat to evaporate from the surface of the residual limb. In an embodiment, the system comprises a liner sock to be worn on the residual limb, and comprising air-permeable textile forming a substantially cylindrical portion that is closed on a distal end and open on a proximal end and comprising an internal surface and an external surface. The liner sock further comprises a friction-interface material that covers only a portion of the internal surface of the air-permeable textile, such that, when worn on the residual limb, the friction-interface material contacts a surface of the residual limb, and an uncovered portion of the air-permeable textile which the friction-interface material does not cover allows air to pass between an external environment of the liner sock and the surface of the residual limb.Type: GrantFiled: November 23, 2022Date of Patent: March 26, 2024Assignees: United States Government As Represented By The Department Of Veterans Affairs, Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.

Patent number: 8949110Abstract: Lines of data that are from a historical document, such as a digitized city directory, have information extracted and stored in searchable data fields. Words and phrases within the lines of data are identified and tagged. Rendering rules are applied to the tagged words and phrases to extract names, addresses, occupations, spouse information and other data, and store that data in the searchable fields.Type: GrantFiled: September 23, 2011Date of Patent: February 3, 2015Assignee: Ancestry.com Operations Inc.Inventors: Peter McCombs, Spencer Koehler, Laryn Brown

Patent number: 8687890Abstract: A city directory, having a listing of names and associated information of residents in a city (or similar location), is digitized. Zones of text having information not useful to users of the digitized directory are removed, and lines of information corresponding to residents are reconstructed, to make the digitized directory more easily accessed and reviewed.Type: GrantFiled: September 23, 2011Date of Patent: April 1, 2014Assignee: Ancestry.com Operations Inc.Inventors: Peter McCombs, Spencer Koehler, Laryn Brown

Patent number: 6491702Abstract: A method and apparatus for defining the location of a medical instrument relative to features of a medical workspace including a patient's body region are described. Pairs of two-dimensional images are obtained, preferably by means of two video cameras making images of the workspace along different sightlines which intersect. A fiducial structure is positioned in the workspace for defining a three dimensional coordinate framework, and a calibration image pair is made. The calibration image pair comprises two 2D projections from different locations of the fiducial structure. After the calibration image pair is made, the fiducial structure is removed. A standard projection algorithm is used to reconstruct the 3D framework of the fiducial structure from the calibration image pair. Appropriate image pairs can then be used to locate and track any other feature such as a medical instrument, in the workspace, so long as the cameras remain fixed in their positions relative to the workspace.Type: GrantFiled: May 29, 2001Date of Patent: December 10, 2002Assignee: Sofamor Danek Holdings, Inc.Inventors: Mark Peter Heilbrun, Paul McDonald, J. Clayton Wiker, Spencer Koehler, William Peters
