Patent number: 7208222Abstract: A porous structure having a plurality of bonded sheets each sheet having at least one aperture that partially overlaps an aperture of at least one other sheet. A method of producing a porous structure including stacking a plurality of sheets each sheet having a multiplicity of apertures, and bonding each sheet to its adjoining sheet. An open-pore network structure having a multiplicity of sheets each having a repeatable pattern. At least a portion of each sheet is bonded to the web of an adjacent sheet. The porous area of at least one of the sheets is askew to the porous area of at least another of the sheets. An open-pore structure having a multiplicity of bonded sheets, each sheet having a repeatable pattern defining a multiplicity of perforations, and a plurality of apertures defined by the repeatable pattern, the apertures extending through the perforations of at least two adjacent plates.Type: GrantFiled: July 23, 2004Date of Patent: April 24, 2007Assignee: Viasys Healthcare Inc.Inventors: Jonathan L.

Publication number: 20030194869Abstract: Method for producing a multiplicity of undercut micro recesses in a surface of an article, such that the article exhibits a greater fractal area at a level below the surface than is exhibited at the surface. The method comprises applying a maskant layer to a selected surface of the article, removing the maskant layer in selected loci to expose underlying portions of the article surface in a selected pattern, applying an etchant to the exposed underlying surface portions for a time sufficient to etch the exposed portions of the article and to enable the etchant to etch beneath portions of the remaining maskant layer, and removing the remaining maskant layer to provide the surface in exposed condition with the multiplicity of undercut recesses, to provide an engineered pattern of the recesses.Type: ApplicationFiled: April 22, 2003Publication date: October 16, 2003Inventors: Mark P. Amrich, Joseph Buturlia, Robert F. Lynch, Jonathan L. Rolfe

Patent number: 6185278Abstract: A focused radiation collimator for collimating radiation emitted from a radiation point source located at a substantially known focal distance from the collimator is disclosed. In one embodiment of the disclosed collimator, the collimator is formed by at least two collimator layer groups, aligned, stacked and bonded together immediately adjacent to one another. Each of the collimator layer groups have a plurality of layer group passages arranged there through in a predetermined pattern which is unique to the layer group but which, with the passages of the other collimator layer group in the aligned stack, additively form a plurality of collimator through channels which are substantially aimed at the radiation point source. Each collimating layer group is formed by at least two substantially identical radiation absorbing layers, aligned, stacked and bonded together immediately adjacent to one another.Type: GrantFiled: June 24, 1999Date of Patent: February 6, 2001Assignee: Thermo Electron Corp.Inventors: Michael P. Appleby, Joseph A. Buturlia, Iain Fraser, Robert F. Lynch

Patent number: 6075840Abstract: Air cross grids, for absorbing scattered secondary radiation and improving radiation imaging in general radiography and in mammography, are provided with a large plurality of open air passages extending through each grid panel. These passages are defined by two large pluralities of substantially parallel partition walls, respectively extending transverse to each other. Each grid panel is made by laminating a plurality of thin metal foil sheets photo-etched to create through openings defined by partition segments. The etched sheets are aligned and bonded to form the laminated grid panel, which is moved edgewise during the radiation exposure to pass primary radiation through the air passages while absorbing scattered secondary radiation arriving along slanted paths.Type: GrantFiled: February 10, 1998Date of Patent: June 13, 2000Assignee: Trex Medical CorporationInventors: Anthony J. Pellegrino, Daniel N Lyke, David P. Lieb, Joseph A. Buturlia, Michael P. Appleby
