Publication number: 20240146896Abstract: An imaging device includes a light source, a controller, and a camera. The camera generates a captured image by obtaining, in a first cycle, an image of infrared light. The camera also captures an image of infrared light (first light) transmitted through a windshield. The light source emits the infrared light in a second cycle. The second cycle for the emission is longer than the first cycle for the generation of the captured image. The controller generates a third image as a difference between a first image and a second image.Type: ApplicationFiled: March 1, 2022Publication date: May 2, 2024Inventors: Kaoru KUSAFUKA, Akinori SATOU, Masato HARA

Patent number: 10852308Abstract: The present invention addresses the problem of developing an analytical method which makes it possible to diagnose early or mild renal disorders. The method is based on calculating a disease-state index value for renal disorders on the basis of the quantities of D-form and/or L-form amino acids, from feces or intestinal content. By comparing the disease-state index value with a threshold value determined from the disease-state index values of a renal failure patient group and a healthy subject group, it is possible to diagnose a mild renal disorder patient group.Type: GrantFiled: June 10, 2016Date of Patent: December 1, 2020Assignees: Kanazawa University, Kagami, Inc.Inventors: Takashi Wada, Kengo Furuichi, Norihiro Sakai, Yasunori Iwata, Akinori Hara, Yusuke Nakade, Kenji Hamase, Yurika Miyoshi, Maiko Nakane, Masashi Mita
