Abstract: A distance sensor for vehicles is provided which includes a sensor device and an electric connector for an electrical connection between the sensor device and a mating connector. The connector includes at least one first terminal pin and at least one second terminal pin. The first terminal pin has a first section leading to the sensor device and a second section extending toward an inlet opening of the connector. The second terminal pin has a first section leading to the sensor device and at least two branched second sections extending toward the inlet opening of the connector. Specifically, the second terminal pin is shaped to provide two-pin plugs, thereby permitting the size of the connector to be reduced, which facilitates ease of installation of the distance sensor to, for example, a bumper of the automotive vehicle.

Abstract: A vehicular ultrasonic sensor apparatus serving as a distance sensor apparatus is equipped with a sensor unit, a case body, a bezel, and a retainer. The retainer includes a pair of pawl members. The pair of pawl members is equipped with a stopper portion. The ultrasonic sensor apparatus is inserted into an attachment hole of the bumper such that a connector portion of the case body is first inserted. When the retainer passes through the attachment hole, the pair of pawl members are elastically deformed. After passing through the attachment hole, the pair of pawl members are elastically restored, and the stopper portion is caught at an inner circumference edge of an exit side of the attachment hole.

Abstract: An information obtaining method includes (1) presenting a first visual stimulus to a living body, (2) obtaining brain activity data in the primary visual cortex and a color vision related area during presentation of the first visual stimulus, (3) presenting a second visual stimulus different from the first visual stimulus to the living body, (4) obtaining brain activity data in the primary visual cortex and the color vision related area during presentation of the second visual stimulus, and (5) obtaining brain activity information on the basis of the ratio between the brain activity data in the primary visual cortex, obtained in (2), and the brain activity data in the primary visual cortex, obtained in (4), and the ratio between the brain activity data in the color vision related area, obtained in (2), and the brain activity data in the color vision related area, obtained in (4).

Abstract: A distance sensor equipped with a mount for mounting the sensor in a mount hole of a bumper of a vehicle. The mount includes a casing with a sensor holder, a bezel, and a resin-made retainer. The bezel is made up of a cylindrical member joined to the sensor holder and a flange having an outer diameter greater than an inner diameter of the mount hole. The retainer includes an annular base joined to the bezel, a plurality of arms, and a plurality of protrusions. The protrusions extend from ends of the arms radially outward of the base and serve to establish a snap-fit on a peripheral edge of the mount hole, thereby nipping a wall of the bumper between the protrusions and the flange tightly to secure the distance sensor to the bumper.
