  • Patent number: 10380635
    Abstract: A first user among a plurality of users is associated with a second user having an evaluation tendency similar to evaluation data of the first user for management. Further, a third user is selected by a terminal device of the first user as a user having preference information that suits preference of the first user. The third user is associated with the first user and the second user for management. This configuration makes it possible to select not only a user automatically selected by a system but also another user whom a targeted user is interested in as a similar user, allowing provision of information that better suits hobby and preference of the targeted user.

  • Publication number: 20190215252
    Abstract: An information management method collects log information of one or more home electrical apparatuses corresponding to service providers. Display screen data is generated which indicates a status of the log information. The display screen data includes groups of information which each contain information on an apparatus, a service provider corresponding to the apparatus, and log information output from the apparatus. Provision of the log information of each group is individually selectable. The display screen data is provided via a network to a display terminal that performs access to a server device. Information is received from the display terminal, which indicates that selection on whether or not provision of the log information is performed. Provision of the log information is not performed on the selected group when a determination is made that refusal of provision of the log information on the selected group is performed.

  • Publication number: 20180152472
    Abstract: An invalidity detection electronic control unit connected to a bus used by a plurality of electronic control units (ECUs) to communicate with one another in accordance with controller area network (CAN) protocol includes a receiving unit that receives a frame for which transmission is started and a transmitting unit that transmits an error frame on the bus before a tail end of the frame is transmitted if the frame received by the receiving unit meets a predetermined condition indicating invalidity and transmits a normal frame that conforms to the CAN protocol after the error frame is transmitted. Even when a reception error counter of the ECU connected to the bus is incremented due to the impact of the error frame, the reception error counter is decremented by the normal frame.
