Patent number: 11937024Abstract: A projection system includes a projection device that projects drawings individually onto a plurality of work spots in a work site. The projection device includes a driver that changes an orientation of the projection device. When drawings are individually projected onto a first work spot and a second work spot in a stated sequence, and the second work spot is outside a projection angle that is projectable by the projection device, the driver changes the orientation of the projection device to include the second work spot within the projection angle after work at the first work spot is finished. The first work spot and the second work spot are included in the plurality of work spots.Type: GrantFiled: January 23, 2020Date of Patent: March 19, 2024Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Yuki Hayashi, Tetsuya Nishi, Keisuke Hara

Patent number: 11812935Abstract: In an endoscope cleaning work support device, an operation reception unit received an input from a cleaner. A display control unit controls the display unit to display a procedure for manual cleaning of an endoscope on a display unit step by step. A measurement unit measures a first period of time from a start time of a procedure in a current step marked by reception of an input for displaying the procedure in the current step by the operation reception unit, to an end time of the procedure in the current step marked by reception of an input for displaying a procedure in a subsequent step by the operation reception unit. A comparison determination unit compares a reference period of time defined for each step for displaying the procedure with the first period of time. The display control unit displays information for alerting the cleaner when the first period of time is shorter than the reference period of time on the display unit.Type: GrantFiled: April 29, 2020Date of Patent: November 14, 2023Assignee: OLYMPUS CORPORATIONInventors: Tetsuya Nishi, Hikari Shimizu, Clarinda Kuan, Kaori Kitano, Yoshiko Ikeda, Takeshi Nishiyama
