Patent number: 7418353Abstract: A method for determining the stresses in a film applied to a substrate from measured substrate shape. The substrate is first analyzed using finite element techniques to obtain nodal forces at the surface of the substrate to which the film is applied, based on measured distortion data of the substrate surface. The film is then analyzed to calculate the film stresses from the applied nodal forces using finite element techniques. The invention may be applied to determine stresses in thin films applied to a variety of substrates, including those used for micro-electronic (e.g., integrated circuit) and micro-mechanical devices and/or for the lithography masks or other optical/projection systems used to fabricate such devices.Type: GrantFiled: October 7, 2005Date of Patent: August 26, 2008Assignee: Wisconsin Alumni Research FoundationInventors: Edward G.

Patent number: 7415889Abstract: A method is disclosed of using external polymeric analytical techniques to predict in-vivo polymeric performance, more particularly, viscoelastic property characterization for performance modeling of biomedical devices that incorporate a polymeric component and are load-bearing during service. Time-Temperature Superposition can be used to accelerate external testing of pertinent properties. Boltzmann's superposition provides a mathematical methodology for determining the time-dependent strain that develops in response to an imposed stress history. The modeling of the present invention provides an opportunity to describe and predict behavior of the device during in-vivo service, as well as it providing a basis for evaluating alternate “candidate” polymers for use in the construction of the device.Type: GrantFiled: January 26, 2007Date of Patent: August 26, 2008Assignee: Polyone CorporationInventor: E.

Patent number: 7415866Abstract: The device for determining the center of gravity of an object measures the moments of the object (e.g., golf club head, or other irregularly shaped object) as it is positioned in three mutually orthogonal axes. As the weight of the object is known, the moments may be divided by the weight to determine the precise arm from the scale to the center of gravity of the object. A line is marked across the exterior surface of the object along each orthogonal axis, with the intersection of the lines defining the center of gravity of the object. A programmable electronic scale is preferably used, but other mechanical and electronic scales may be used as well. The knowledge of the precise location of the center of gravity of the object enables a technician to add or remove weight in precise amounts and locations to adjust the center of gravity precisely.Type: GrantFiled: February 14, 2006Date of Patent: August 26, 2008Inventor: Mondher Latiri
