Patent number: 8438893Abstract: A two-dimensional sheet material is provided that is suitable for bending along a bend line to form a three-dimensional object. The sheet material is provided with a plurality of displacements in a thickness direction of the sheet material on one side of the bend line. A portion of the displacements shear adjacent the bend line and define an edge and an opposed face. The edge and opposed face configured to produce edge-to-face engagement of the sheet material during bending. Alternatively, sheet material is provided with a plurality of displacements in a thickness direction of the sheet material on one or both sides of the bend line, and with a plurality of corresponding and cooperating protrusions to improve structural integrity and/or to improve electromagnetic and radio frequency shielding. The sheet material may also be provided with a self-latching structure. A method of preparing and using these sheet materials is also described.Type: GrantFiled: August 30, 2010Date of Patent: May 14, 2013Assignee: Industrial Origami, Inc.Inventors: Max W. Durney, Radha Vaidyanathan, Ryan Lam

Publication number: 20090100895Abstract: A substantially two-dimensional sheet material is configured for bending along a bend line to form a three-dimensional structure having a hinge along the bend line. The sheet material includes a substantially two-dimensional in a region in which a bend is to be made, and a plurality of displacements in a thickness direction of the sheet material along opposing sides of the bend line, each displacement having a sheared edge extending between end portions thereof and substantially parallel to the bend line. The adjacent sheared edges overlap one another with respect to the bend line to form a hinge structure therebetween extending along the bend line, the hinge structure having hinge ends that conform in shape with the end portions. The hinge structure is dimensioned and configured for multiple bend and unbend cycles thereby providing a monolithic hinge connecting opposing panels of the sheet material on opposing sides of the bend line.Type: ApplicationFiled: September 22, 2008Publication date: April 23, 2009Applicant: Industrial Origami, Inc.Inventors: Max W.

Sheet of Material with Fluid-Resistant Bend Controlling Displacements and Method of Forming the Same
Publication number: 20090100894Abstract: A method of preparing a two-dimensional sheet of material for bending along a bend line to form a three-dimensional article having a fluid-resistant bend includes the steps of forming at least one bend-controlling displacement in the thickness direction of the sheet of material, a portion of a periphery of the bend-controlling displacement proximate the bend line defining a sheared face directed toward an opposed sheet surface in the sheet of material on an opposite side of the bend line, and bending the sheet of material. A balancing of the forces during bending produces face-to-surface engagement between the sheared face and the opposed sheet surface such that the sheet material is substantially fluid-resistant along the bend line.Type: ApplicationFiled: September 22, 2008Publication date: April 23, 2009Applicant: Industrial Origami, Inc.Inventors: Max W.

Patent number: 5809283Abstract: A method of simulating a system on a computer. The method comprises the following steps. First, analyze a hardware design language specification of the system to identify a set of processes. The hardware design language specification includes a register transfer level definition of a part of the system. Identify a set of triggered processes from the set of processes. Identify a set of triggers for the set of triggered processes, where a first trigger of the set of triggers is for causing a state change in a simulation of the system. Determine an evaluation order of the set of processes using the set of triggers. Simulate the system using the evaluation order.Type: GrantFiled: September 29, 1995Date of Patent: September 15, 1998Assignee: Synopsys, Inc.Inventors: Radha Vaidyanathan, Ping-sheng Tseng
