Publication number: 20120209146Abstract: An aspiration chamber is provided with an aspiration aperture, having a shape in which a width becomes larger from one edge toward another edge, and aspirates soft tissue through the aspiration aperture. A deformation amount measurement portion measures aspiration deformation amounts of the soft tissue within the aspiration aperture along a virtual line from the one edge to another edge. Based on the aspiration deformation amounts that have been measured by the deformation amount measurement portion, a computer uses a finite element model of the soft tissue to derive an approximation equation according to a numerical function for the aspiration deformation amounts and positions on the virtual line and determines a distribution of elasticity from the surface of the soft tissue into its interior by substituting parameters of the approximation equation into estimation equations that are derived by assuming that the deformation along the virtual line reflects elasticity distribution parameters.Type: ApplicationFiled: November 4, 2010Publication date: August 16, 2012Applicant: NATIONAL UNIVERSITY CORPORATION NAGOYA INSTITUTE OF TECHNOLOGYInventors: Takeo Matsumoto, Shinichi Miyano, Kazuaki Nagayama

Publication number: 20120075878Abstract: Three-dimensional information is presented directly on the surface of a target three-dimensional object without using a display device such as a display monitor and an HUD. Spatially coded light patterns are projected from two projectors on a target object surface. The light projected from the two projectors are added up on the object surface to produce unified color and luminance. On the object surface, light is simply added up, so that a pattern whose color and brightness correspond to distance and height appears. Hence, a distance to an object or a three-dimensional shape of an object can be highlighted by the color and brightness presented on the object for perception by human beings.Type: ApplicationFiled: June 7, 2010Publication date: March 29, 2012Applicant: National University Corporation Nagoya Institute of TechnologyInventors: Jun Sato, Fumihiko Sakaue, Masahiko Inagaki
