Abstract: A heating part of this radiant heater has a plurality of heating wires. The plurality of heating wires are connected in parallel such that a plurality of parallel groups may be formed by electrodes. Further, the plurality of parallel groups are connected in series by the electrodes. The heating parts are set to reach a radiation temperature for emitting the heat radiation which makes a human to feel warmth. The heating parts have a thermal resistance in a longitudinal direction which is set, when an object contacts on the surface, a temperature of the part where the object touches falls to a suppressed temperature lower than the radiation temperature. The temperature of the heating part increases rapidly in response to electric supply. When there is a contact with an object, the temperature of the heating part decreases rapidly.

Abstract: A raindrop recognition device is configured to recognize a raindrop on a transparent panel. The raindrop recognition device includes a storage unit, an image input unit, and an image recognition unit. The storage unit stores a trained model that is a machine learning model trained using, as training data, images of the transparent panel with adhered raindrops and images of the transparent panel without adhered raindrops. Image data of the transparent panel taken by a camera is input to the input unit. The image recognition unit is configured to calculate a value representing a raindrop likeness of an object on the transparent panel in the image data by inputting the image data to the trained model. The trained model is trained by training data including images of the transparent panel with uniform background and images of the transparent panel with light source.
