Patent number: 10794708Abstract: A server system includes a communicator, a storage, and a controller. The controller is configured or programmed to receive positional information of a watercraft that a user of a wireless communication terminal is aboard and propulsion device information from the wireless communication terminal through the communicator. The propulsion device information indicates a type of a propulsion device on the watercraft. The controller creates cruise trajectory information and stores the created cruise trajectory information in the storage based on the positional information of the watercraft in association with the type of the propulsion device on the watercraft. The controller determines a frequency at which cruise trajectories of the watercraft match the cruise trajectories based on the cruise trajectory information in the storage. The controller creates cruise route information in association with the type of the propulsion device on the watercraft.Type: GrantFiled: March 29, 2018Date of Patent: October 6, 2020Assignee: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventors: Shu Akuzawa, Yoshimasa Kinoshita, Masaru Tamaki

Publication number: 20160006635Abstract: A monitoring method and system avoid the occurrence of waiting due to deadlock, and thereby avoid the occurrence of job delays. An information system includes a job scheduling device which receives a request, and an analyzing device which retains first information related to the exclusive relation between jobs and a load tendency of each of the jobs. The job scheduling device makes an inquiry to the analyzing device with respect to which business device the request should be transferred. The analyzing device notifies the job scheduling device of the business device to which the request should be transferred and, as needed, a standby time, and the job scheduling device transfers the request to the designated business device after standing by for the designated standby time, in case the standby time is designated, based on the notice from the analyzing device.Type: ApplicationFiled: December 25, 2013Publication date: January 7, 2016Applicant: HITACHI, LTD.Inventors: Shinichi YOKOTA, Masaru TAMAKI, Toshimichi SASAGE
