Abstract: According to an embodiment, an optical inspection method includes: causing a wavelength selection portion to selectively pass light components including at least two different wavelength spectra from an object point and causing an imaging portion including at least two color channels configured to receive the light components of the wavelength spectra to capture the object point; defining the light components of the at least two different wavelength spectra as signal vectors having different directions based on light reception data in the at least two color channels for the object point; and estimating spread of a direction distribution of light at the object point based on the directions of the signal vectors.

Abstract: According to the embodiment, an optical inspection method for a surface state of a subject includes acquiring and discriminating. The acquiring includes acquiring a color vector of a color corresponding to a wavelength spectrum in a color coordinate system of n dimensions (n is a natural number equal to or larger than 1), which is equal to or smaller than a number of a plurality of color channels of pixels of an image sensor, with optical imaging using a wavelength spectrum selection portion that selectively allows a plurality of wavelength spectra different from one another from a surface of the subject to pass. The discriminating includes discriminating the surface state of the subject based on a direction of the color vector in the color coordinate system.

Abstract: According to one embodiments, a wearing detection apparatus includes a restraint device, an imaging device, a control unit, and an output device. The restraint device is to restrain a passenger seated in a seat, and includes a strap an exposed area of which changes when the strap is being worn and not worn. The imaging device captures an image of the restraint device including the strap. The control unit detects from the image captured by the imaging device, a recognition image corresponding to a recognition member provided in an area that is exposed when the strap is worn. The output device outputs a result of detection of the recognition image.

Abstract: A vehicle-mounted gateway apparatus according to an embodiment includes a communication device including an external communication interface for connection to the network outside the mobile body with each of a plurality of different external communication schemes and an internal communication interface for connection to each of the plurality of data sources within the mobile body; and a control device configured to transmit data collected from each of the data sources through the internal communication interface to the network outside the mobile body. The control device includes a communication channel selection section configured to select a communication channel from the plurality of external communication schemes for each of the data sources, and a monitoring control section configured to monitor data output from each of the data sources and to transmit the data to the network outside the mobile body over a selected one of the communication channels associated with the data source.

Abstract: A tunnel-expansion portion is provided at a front portion of a tunnel portion. The tunnel-expansion portion projects upward greatly and widely so as to provide components of an exhaust system that extend rearward from an exhaust manifold therein (outside a vehicle compartment). Accordingly, there can be provided a front structure of a vehicle, in which an engine is laterally disposed in an engine room at a front portion of the vehicle, an intake pipe is disposed in front of the engine, and an exhaust pipe is disposed in back of the engine, which can improve an exhaust efficiency and a vehicle safety against a vehicle crash, without providing an improperly-large longitudinal space between the engine and the dash panel.
