An inflator for an air-bag comprises at least one gas bottle containing pressurized gas. Each of the latch assemblies include an actuatable latch pin to release the rotatable hook, and upon release, the latch assemblies are gravity driven to return to a latching position in which the rotatable hooks are re-engageable. Further, relative positions and orientations of the capturing apparatus and the object relative to each other are calculated on the basis of the detected vertices, and a virtual camera in a virtual space is set on the basis of the positions and the orientations. For example, for those engines which utilize smoke limiting maps, when the injectors are not performing as expected, the injection adjustments that result from use of the smoke limiting maps can sometimes become fruitless.
