Abstract: An adhering matter determination portion includes an irradiation portion, a light receiving portion and a determination portion. The irradiation portion radiates a light to a plurality of different areas of a transparent plate. The light receiving portion converts reflected waves reflected at the different areas into electrical signals. The determination portion compares at least one of detection signals outputted from the light receiving portion with a determination threshold. When the detection signal is lower than the determination threshold, the determination portion determines that there is an adhering matter on the transparent plate. The determination portion compares the detection signals. When a difference of the detection signals is higher than a condensation determination value, the determination portion determines that the adhering matter is raindrops. When the difference of the detection signals is lower than the condensation determination value, the determination portion determines that the adhering matter is dewdrops.

Abstract: A driver is awakened by measuring a drowsiness level of the driver; detecting a behavior of the driver indicating that the drive is aware of drowsiness; setting an intensity of an awakening stimulus based on the drowsiness level and a detection result of the behavior; and generating the awakening stimulus according to the intensity. The intensity is set to be higher when the behavior of the driver is detected under a same drowsiness level than when the behavior of the driver is not detected.

Abstract: An optical component for reflecting incident light at a predetermined reflection angle, includes: a scan portion having a reflection surface and scanning the reflection angle; and a package accommodating the scan portion, and having a main body of a box shape with one open surface and a lid which covers the one open surface and transmits the incident light and reflected light. The lid includes at least one base portion having a counter surface facing the reflection surface and a back surface opposed to the counter surface, and a diffraction lens portion arranged on at least one of the counter surface and the back surface and having a periodic concavo-convex shape so as to widen the reflection angle.

Abstract: A seat reclining position control device includes: a seat on which an occupant of a vehicle sits; an adjustment part configured to adjust an angle of a backrest of the seat; a sleep state detection unit configured to detect a sleep state of the occupant; a control unit that operates the adjustment unit to control the angle; and a vehicle interior detection unit configured to detect a vehicle interior state of the vehicle. The control unit implements a seat angle control to adjust the angle of the backrest for the occupant in the sleep state based on the vehicle interior state to a suitable sleeping angle suitable for sleeping when the sleep state detection unit detects the sleep state of the occupant.
