Patent number: 11971721Abstract: To effectively enhance the operation efficiency of an autonomous mobile robot, an autonomous mobile robot control system includes a processor and a plurality of environmental cameras. The processor estimates a moving route of each of a plurality of moving bodies on the basis of characteristics of each of the plurality of moving bodies and sets a subset of the plurality of moving bodies whose moving routes overlap among the detected moving bodies as avoidance processing target moving bodies. The processor generates an avoidance procedure for the avoidance processing target moving bodies so the motion of the avoidance processing target moving bodies does not interfere with the motion of other avoidance target moving bodies.Type: GrantFiled: August 3, 2021Date of Patent: April 30, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tomohisa Takai, Yuhei Yamaguchi, Satoshi Toyoshima, Yuta Watanabe, Tetsuya Taira, Mikio Honda, Shiro Oda, Nobuhisa Otsuki

Patent number: 6098069Abstract: As the user inputs a URL (Uniform Resource Locator) specifying specific data, the data managing method in accordance with the present invention obtains the specific data and all the constituent data composing the specific data from the network according to the reference information. Thereafter, the obtained data is reconstructed into a data file and recorded as page data, and index information in which the URL is paired with a position of each piece of data on the page data is added to the page data. Since the obtained data is saved as a single data file, the user can process the obtained data easily. Besides, since the URL used on the network is used as the index information with no modification at all, the obtained data does not lose the relevance to the original data thereof.Type: GrantFiled: March 4, 1998Date of Patent: August 1, 2000Assignee: Sharp Kabushiki KaishaInventor: Tomohisa Yamaguchi
