  • Publication number: 20250139148
    Abstract: An information processing system includes an agent device and an information processing device. The agent device has an agent function. The information processing device generates dialogue sentence data for a user. The information processing system outputs the generated dialogue sentence data to the user using the agent function. The information processing device includes: a load estimation unit that estimates a load when the user recognizes the dialogue sentence data; and a data generation unit that generates the dialogue sentence data using response sentence information classified into positive sentences and negative sentences. When the load of the user is relatively high, the data generation unit increases a proportion of the positive sentences used in the dialogue sentence data as compared to when the load of the user is relatively low.

  • Patent number: 12280686
    Abstract: A charge-discharge control system is provided in which each of a plurality of charge-discharge elements autonomously controls charging-discharging. The charge-discharge control system includes an external control device that broadcasts a control signal to the charge-discharge elements that perform charging-discharging; and an authentication device that permits charging-discharging of each of the charge-discharge elements. The charge-discharge elements having received the control signal transmit, to the authentication device, a permission request signal, which is based on the received control signal.

  • Patent number: 12194991
    Abstract: An occlusion is identified in a vehicle transportation network. A visibility grid is identified on a second side of the occlusion for a vehicle that is on a first side of the occlusion. The visibility grid is identified with respect to a region of interest that is at least a predefined distance above ground. The visibility grid is used to identify first portions of roads sensed by a sensor positioned on the vehicle and second portions of the roads that are not sensed by the sensor. A driving behavior of the vehicle is altered based on the visibility grid.
