  • Patent number: 10591922
    Abstract: Arrangements related to operating an autonomous vehicle in view-obstructed environments are described. At least a portion of an external environment of the autonomous vehicle can be sensed to detect one or more objects located therein. An occupant viewable area of the external environment can be determined. It can be determined whether one or more of the detected one or more objects is located outside of the determined occupant viewable area. Responsive to determining that a detected object is located outside of the determined occupant viewable area, one or more actions can be taken. For instance, the action can include presenting an alert within the autonomous vehicle. Alternatively or in addition, the action can include causing a current driving action of the autonomous vehicle to be modified.

  • Patent number: 10288303
    Abstract: A room air conditioning system includes a plurality of indoor units and a controller. Each of the plurality of indoor units includes: an air conditioner main body having a plurality of blow-off openings formed therein; a plurality of flaps rotatably that are disposed in the respective blow-off openings and that can independently change vertical angles of airflows; and a human body sensor that detects whether a person is present below a corresponding one of the plurality of indoor units. When at least one of the human body sensors in the plurality of indoor units detects the absence of a person in a state of selecting the airflow control, the controller causes a corresponding one of the indoor units that detects the absence to perform the temperature evenness control. This room air conditioning system successfully reduces unevenness of room temperature.
