Patent number: 11881304Abstract: A medical information processing apparatus according to an embodiment includes a processing circuitry. The processing circuitry is configured: to distribute, to an information processing apparatus provided at each of a plurality of medical institutions, a program for causing a machine learning process to be executed by using medical data held at the medical institution having the information processing apparatus; to receive, from each of the information processing apparatuses, a change amount in a parameter related to the machine learning process, regarding a change caused in conjunction with the execution of the machine learning process; to adjust a value of the parameter on the basis of the received change amount; and to transmit the adjusted parameter to each of the information processing apparatuses to cause the machine learning process to be executed on the basis of the parameter.Type: GrantFiled: June 4, 2020Date of Patent: January 23, 2024Assignee: CANON MEDICAL SYSTEMS CORPORATIONInventors: Keita Mitsumori, Yasuhito Nagai

Publication number: 20210379786Abstract: Provide a safer cutting machine. A front portion detection means that is spaced downward from the lower end of the clamp gauge by a first predetermined distance and is positioned near the front edge of the clamp gauge in die front-rear direction of the clamp gauge, and a first predetermined distance from the lower end of the clamp gauge. The rear portion detection means and the clamp gauge which arc spaced apart from each other by a second predetermined distance different from the above distance and which are arranged at the rear portion of the front portion detection means in the front-rear direction of the clamp gauge move in the vertical direction.Type: ApplicationFiled: June 10, 2019Publication date: December 9, 2021Inventors: Michio NAGAI, Yasuhito NAGAI
