Abstract: An apparatus detecting driving incapability state of a driver includes: a head detection portion that detects a head of the driver based on an image of a driver's seat captured by an imaging device mounted on a vehicle; and a shake detection portion that detects the driver is incapable of driving when an amplitude of a shake of the head detected by the head detection portion is smaller than a first amplitude or larger than a second amplitude, which is larger than the first amplitude, before a shake determination time elapses after external force has been applied to the vehicle during travel of the vehicle.

Abstract: The display system includes a first storage unit storing standardized data composed chromaticity values and luminance values. An information acquirer acquires luminance values and chromaticity values of a visual target and luminance and chromaticity values of a background thereof. A standardization unit standardizes the chromaticity values and the luminance values of the visual target and the background based on these chromaticity values and the luminance values of the visual target and the background thereof and the standardized data stored in the first storage unit. A visual target contrast calculator calculates a contrast of a visual target to a background by measuring a distance in a color space between the visual target and the background each defined by the standardized luminance and chromaticity values. A second storage unit stores an expression defining a relation between the contrast thereof to the background and a size of the visual target.

Abstract: Apparatus detecting driving incapability state of a driver includes: a head detection portion that successively detects a head portion, which is higher than a neck of the driver, based on an image of a driver's seat captured by an imaging device mounted in a vehicle; and an out-of-frame state detection portion that detects that the driver is incapable of driving, when the head portion detected by the head detection portion is out of a predetermined scope in the image during travelling of the vehicle.

Abstract: A current sensor includes: a magneto electric conversion element; and a magnetic field concentrating core applying a magnetic field caused by a measurement object current to the magneto electric conversion element. A planar shape of the magnetic field concentrating core perpendicular to a current flowing direction is a ring shape with a gap. The magneto electric conversion element is arranged in the gap. A part of a conductor for flowing the current is surrounded by the magnetic field concentrating core. The magnetic field concentrating core includes two first magnetic members and at least one second magnetic member, which are stacked alternately in the current flowing direction. Parts of the two first magnetic members adjacent to each other via the one second magnetic member are opposed to each other through a clearance or an insulator.
