Patent number: 10479068Abstract: There is provided an additive manufacturing system comprising a vertical stage (also known as a z-stage) that moves the object being created along an axis of motion that is not perpendicular to the image plane (non-parallel to the z-axis of the image plane). By moving the build platform, upon which the additively manufactured object is being supported, along a predetermined axis of motion, such as one adapted to the dominant axis of the object design, the additive manufacturing system is capable of making larger objects, shortening build times, improving part resolution, and/or reducing the volume of photocurable material needed, among other benefits.Type: GrantFiled: March 23, 2017Date of Patent: November 19, 2019Assignee: 3D Systems, Inc.Inventors: Patrick Dunne, Peter Scott Turner, Seth Astle

Patent number: 10376816Abstract: A separation system for the removal of suspended solids from raw fluid. Raw fluid is placed in a non-pressurized settling tank and allowed to partially settle before injection into a pressurized clarification vessel. Following a dwell period clarified fluid is discharged at the top of the clarification vessel and settled waste is removed at the bottom thereof. Constant vessel pressure is maintained during injection of raw fluid or the discharge of clarified fluid or settled waste. The system is simpler to manufacture and more efficacious in its use than prior art methods.Type: GrantFiled: April 13, 2015Date of Patent: August 13, 2019Assignee: Innovation Water Clarification, Inc.Inventor: Patrick Dunne

Patent number: 8703037Abstract: A solid imaging apparatus and method employing sub-pixel shifting in multiple exposures of the digitally light projected image of a cross-section of a three-dimensional object on a solidifiable liquid medium. The multiple exposures provide increased resolution, preserving image features in a three-dimensional object and smoothing out rough or uneven edges that would otherwise be occur using digital light projectors that are limited by the number of pixels in an image projected over the size of the image. Algorithms are used to select pixels to be illuminated within the boundary of each image projected in the cross-section being exposed.Type: GrantFiled: June 9, 2010Date of Patent: April 22, 2014Assignee: 3D Systems, Inc.Inventors: Charles W.

Patent number: 8055455Abstract: A method, apparatus, and computer usable program code for identifying change indices for a structure. In one advantageous embodiment a method receives a response signal in response to a transmission of an interrogation signal into the structure. The response signal is decomposed into a first plurality of modes. The first plurality of modes is compared to a second plurality of modes for a comparison signal to form a comparison. A change index is assigned to the response signal using the comparison.Type: GrantFiled: June 9, 2008Date of Patent: November 8, 2011Assignee: The Boeing CompanyInventors: Jeong-Beom Ihn, James Patrick Dunne, Lawrence E.
