Abstract: A raindrop detection device includes: a front monitoring camera for photographing a front of a vehicle through a windshield of the vehicle; a raindrop detection camera for photographing a raindrop adhering to the windshield; and an electronic control unit disposed away from the windshield, the front monitoring camera, and the raindrop detection camera, performing an image processing on an image data of a front image from the front monitoring camera, and performing an image processing on an image data of a windshield image from the raindrop detection camera.

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.

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 lens shape measuring apparatus measures a peripheral shape of a lens in order to measure the peripheral shape of the lens accurately according to a non-contact technique. The lens shape measuring apparatus includes: a lens holding mechanism section for holding the lens with the holding axis from the side of a lens surface; and a laser displacement meter for measuring a lens peripheral shape by irradiating a laser beam to the periphery of the lens and receiving a reflected light thereof. The laser displacement meter is installed such that a light projecting section for projecting a laser beam and a light receiving section for receiving a laser beam are aligned in a direction perpendicular to an axis line of the holding axis.
