Abstract: A gating camera divides a field of view in a depth direction into multiple slices, and generates multiple slice images that correspond to the multiple slices. An illumination apparatus emits illumination light. A camera controller controls a light emission timing of the illumination apparatus and an exposure timing of an image sensor so as to generate slice images from a near slice to a farther slice. An arithmetic processing device judges whether a road surface appears for each of the slice images generated in sequence. Processing for a row judged to include a road surface in a given slice is simplified at the time of sensing of a slice farther than the given slice.

Abstract: An attack status evaluation apparatus (100) that emulates a cyberattack that steals information includes a degree of goal achievement calculation unit (105) and an attack route change determination unit (106).

Abstract: A state detection system includes a server and an apparatus. The apparatus includes one or more internal devices, a first control module, a determination module, a first storage module, and a first communication module. The control module acquires signal information from each internal device.

Abstract: Provided are a method and an apparatus for resistance spot welding in which preliminary current application is executed and then main welding is executed in accordance with master patterns of various parameters obtained during the preliminary current application. The main welding is executed under welding conditions of the master patterns, and whether a welding abnormality has occurred and whether the welding abnormality is likely to occur are determined. When the welding abnormality is likely to occur, the welding conditions for the main welding are corrected so as to prevent the welding abnormality. When the welding abnormality is unlikely to occur, the welding conditions for the main welding are corrected so as to match the master patterns.

Abstract: While a laser-beam application position is moved along a locus which circularly or elliptically circles around a locus center so as to cross a weld line that is a boundary between a first metal plate and a second metal plate overlapped with each other, the locus center is moved in a direction parallel to a weld line.

The unmelted zone is located downstream of a range through which the laser beam has already passed in the direction parallel to the weld line.
