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.

Abstract: When it is confirmed that a user exists based on an image of the situation outside a vehicle which is captured using a camera and a proximity sensor detects a fact that the user is approaching based on, for example, a putting of a hand of the user over the proximity sensor, a control device causes a ramp to be extended. As such, a user sitting in a wheelchair can cause the ramp to be extended by approaching the proximity sensor, such as the putting of the user's hand over the proximity sensor such that the user sitting in the wheelchair does not have to press an extension/storage button provided on the vehicle to cause the ramp to be extended.
