An ECU of a night vision system stores small obtained images of provisional targets as six templates depending on the distance from infrared cameras, and selects one of the templates depending on the distance up to an actual object. The present invention also relates to a method for treating neoplastic disease using a composition comprising a catechin compound, ascorbic acid, proline and lysine. There is no color change due to the use of the stroboscopic light and the image having natural color reproduction can be obtained. A fiberglass resin and cloth are applied to the structure. A soil moisture sensor, which is also useful as a leaf wetness sensor, incorporates a novel self calibrating capacitive sensor structure. Below the two tubular members a fluid outlet is provided with a connector for joining to a drainage system for draining the chemically treated condensate water from the cavity.
