Patent number: 11532401Abstract: A risk evaluation system is provided with an imager and a controller. The imager takes images at different times of equipment having zones that do not overlap each other, and outputs the images that are taken. The controller detects a contact count of a number of times a living body contacts each of the zones in accordance with the images, decides evaluation information about a contact infection risk in each of the zones in accordance with the contact count, and outputs the evaluation information.Type: GrantFiled: March 16, 2020Date of Patent: December 20, 2022Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventor: Yuki Kushida

Patent number: 11248249Abstract: The present invention provides a method for determining whether or not a sample contains at least one of Cercospora fungus and Pseudocercospora fungus. In the method, first, the sample is added an aqueous solution containing N,N,N?,N?-Tetramethyl-1,4-phenylenediamine and 5-(2,4-disulfophenyl)-3-(2-methoxy-4-nitrophenyl)-2-(4-nitrophenyl)-2H-tetrazolium to provide a mixture. The aqueous solution has a pH of not less than 5.1 and not more than 6.5. Then, the mixture is irradiated with light having a wavelength of 400 to 500 nanometers to measure a first absorbance Ay of the mixture, and the mixture is irradiated with light having a wavelength of 500 to 800 nanometers to measure a second absorbance Ax of the mixture. If the value of Ay/Ax is not less than 1.5 or the mixture is orangey, it is determined that the sample contains at least one of Cercospora fungus and Pseudocercospora fungus.Type: GrantFiled: September 5, 2019Date of Patent: February 15, 2022Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Yuki Kushida, Yosifumi Kariatumari
