    摘要: A raindrop sensor includes an image sensor and an image processor. The image sensor captures an image of a windshield from inside a vehicle. The image processor performs a frequency analysis of the image to detect a high-frequency component in the image. When the high-frequency component is detected, the image processor detects a width of a change region where a change in gradation of the image occurs. When the width of the change region is within a predetermined range corresponding to a diameter of a raindrop, the image processor determines that the raindrop is on the windshield. Even when a foreign matter such as a water stain appears as the high-frequency component as a result of the frequency analysis, the raindrop and the foreign matter can be distinguished from each other based on the width of the change region.

    摘要: An illumination control unit includes an automatic control function for automatically controlling the turning on and off of vehicle head lights depending on brightness of an environment around a vehicle. A sensitivity adjuster is installed on a lever extending from a steering column in a vehicle compartment. The sensitivity to the brightness of the environment around the vehicle at the time when the auto-on and auto-off state of the vehicle lights is changed can be adjusted with the sensitivity adjuster.

    摘要: A radiator is provided with a looped radiation conductor, a capacitor, an inductor, a feed point on the radiation conductor, and a dielectric block provided in a portion where the radiation conductor and the ground conductor are close to each other. At a low-band resonance frequency, a current flows through a path extending along an inner perimeter of the loop of the radiation conductor and including the inductor and the capacitor. At a high-band resonance frequency, a current flows through a path including a section extending along an outer perimeter of the loop of the radiation conductor, including the capacitor but not including the inductor, and extending between the feed point and the inductor, and a parallel resonant circuit is formed from: a capacitance between the radiation conductor and the ground conductor between which the dielectric block is provided; and an inductance of the radiation conductor.

    摘要: An antenna apparatus includes a slit provided on an antenna element between first and second feed ports; and a series resonant circuit provided at a location along the slit, with a distance from an opening of the slit. When the antenna apparatus operates at a first isolation frequency identical to a resonance frequency of the series resonant circuit, the series resonant circuit is short-circuited, and only a section of the slit from its opening to the series resonant circuit resonates, thus providing isolation between the feed ports at the first isolation frequency. When the antenna apparatus operates at a second isolation frequency lower than the first isolation frequency, the series resonant circuit is open, and the entire slit resonates, thus providing isolation between the feed ports at the second isolation frequency.
