Patent number: 9212902Abstract: A range image obtaining system for a track includes a laser slit light source disposed within a plane perpendicular to a tread of a rail and emits laser slit light within the plane; a two-dimensional image imaging device which is disposed to have an angle with respect to the plane perpendicular to the tread of the rail and obtains a light sectioning image generated from the laser slit light; and an image signal processing device for generating a range image based on a distance from the two-dimensional image imaging device based on the light sectioning image.Type: GrantFiled: June 29, 2011Date of Patent: December 15, 2015Assignees: KAWASAKI JUKOGYO KABUSHIKI KAISHA, EAST JAPAN RAILWAY COMPANYInventors: Masayuki Enomoto, Tadao Shimada, Yohichi Nakamura, Keita Kataoka, Hiroyuki Matsuda, Masanobu Kozeki

Patent number: 9008406Abstract: Provided are a method capable of discriminating between a colony of differentiated pluripotent stem cells and a colony of undifferentiated pluripotent stem cells, and a method for automatically culturing undifferentiated pluripotent stem cells and a system thereof. A differentiated colony composed of differentiated pluripotent stem cells, an undifferentiated colony composed of undifferentiated pluripotent stem cells and a multilayered colony having pluripotent stem cells stacked in multiple layers are discriminated by processing a photo image of a colony including pluripotent stem cells in a culture vessel. Specifically, a colony having a luminance higher than a first threshold A is determined as a differentiated colony, a colony having a luminance equal to or lower than the first threshold A and equal to or higher than a second threshold B is determined as an undifferentiated colony, and a colony having a luminance lower than the second threshold B is determined as a multilayered colony.Type: GrantFiled: October 7, 2010Date of Patent: April 14, 2015Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Keizo Watakabe, Yohichi Nakamura, Osamu Ohji, Katsumi Nakashima
