By providing dummy pixels separately from effective pixels, the total number of pixel rows is equalized with the number of horizontal sync signals included in one frame interval. To verify the validity of a sheet of material, the edge code is read, the same physical property is measured and the measured value is compared with the previously stored value extracted from the measure database. A portion of the lower metal plate is exposed via the LED-receiving hole and an LED is mounted on the exposed portion of the lower metal plate and is electrically connected to both of the upper and lower metal plates. Removable snap-mounted flanges may also be included in the exit trough. The resulting regulation of such ocean water property profiles may then also indirectly affect the properties of the atmosphere above the ocean so that the system can be said to affect planetary properties both oceanic and atmospheric. The first andor second contour are at least partially circular with a radius of the outer radius of the gearwheel, and the teeth andor the pawl tooth have, in the area of the front tooth flank of the gearwheel or parking lock pawl, a crown tip relief relative to the outer radius of the gearwheel.
